5Motion Technology

SOX (NBR)-Rubber-Nitrile Butadiene (Buna N) Rubber

is a flexible elastomer material that is oil resistant,

resembles natural rubber in resilience and elasticity -40° to+100°C 1° .015 80A HIGH GOOD BLACK

and operates effectively in temperature range of -40°

to +100°C. Good resistance to oil.Standard elastomer.(Also applies to SXB Cushions.)

URETHANE LS Jaw-in-Shear (Split) is radially removable

meaning that neither hub (or driver/driven equipment) -34° to 93°C 2° .030 to .047 55D L O W GOOD BLUE

has to be moved to make replacements of spider.

This saves time and money in maintenance cost.URETHANE-Urethane has greater torque capability 55D

than NBR (1.5 times), provides less dampening effect, L050-L095

and operates at a temperature range of -34° to+71°C. -34° to+71°C 1° .015 40D L O W VERY GOOD BLUE

Good resistance to oil and chemicals. L099-L225

HYTREL-Hytrel is a flexible elastomer designed forhigh torque and high temperature operations. Hytrel

can operate in temperatures of -51°to+121°C and has

an excellent resistance to oil and chemicals. -51° to 121°C 1/2° .015 55D L O W EXCELLENT TAN

Not recommended for cyclic or start/stop applications.

BRONZE-Bronze is a rigid, porous oil-impregnatedmetal insert exclusively for slow speed (maximum -40° to +232°C 1/2° .010 .... NONE EXCELLENT BRONZE

250 RPM) applications requiring high torque

capabilities. Bronze operations are not affected by

extreme temperatures, water, oil, or dirt.

Note 1: NBR standard shore hardness is 80A+5A - Except L035=60A. Other softer or harder designs are available in NBR material; consult Lovejoy.

SHAFT COUPLINGS S-Flex Selection Data

Elastomer-in -Shear Type Couplings

The simple design of the S-Flex coupling ensures ease ofassembly and reliable performance. No special tools areneeded for installation or removal. S-Flex couplings canbe used in a wide variety of applications.

Features and Benefits:� Easy to Install.� Maintenance Free.� No Lubrication.� Dampens Vibration and Controls Shock.� Torsionally Soft.� Double Engagement.

The S-Flex coupling design is comprised of three parts.Two flanges with internal teeth engage an elastomeric flex-ible sleeve with external teeth. Each flange is attached tothe respective shaft of the driver and driven and torque istransmitted across the flanges through the sleeve. Mis-alignment and torsional shock loads are absorbed by sheardeflection in the sleeve. The shear characteristic of the S-Flex coupling is very well suited to absorb impact loads.

The S-Flex coupling from Lovejoy offers combinations offlanges and sleeves wihich can be assembled to suit yourspecific application. Thirteen sizes are available with torquecapabilities that range from 60 in-lb to 72,480 in-lb.

The S-Flex flanges are offered in four models which aremade from zinc die cast or cast iron. Sleeves are avail-able in EPDM rubbber, Neoprene, or Hytrel to address awide variety of application requirements.

Flange Types:Type J - Zinc Die Cast and Cast Iron, Bore Range... 3/8�-1-7/16�Type S - Cast Iron, Bore Range... 1/2�- 5-1/2�Type B - Cast Iron w/QD BushingType SC - Cast Iron SpacerType T - Cast Iron w/Taper-lock bushing

Hubs for Type SC Spacer Coupling:Type H - Powdered Metal or Cast Iron, Standard LengthType HS - Powdered Metal or Cast Iron, Short Length

Sleeves Types:JE - (EPDM) 1-piece solidJES - (EPDM) 1-piece splitJN - (Neoprene) 1-piece solidJNS -(Neoprene) 1-piece splitE - (EPDM) 2-piece with retaining ringN - (Neoprene) 2-piece with retaining ringH - (Hytrel) 1-pieceHS - (Hytrel) 2-piece split

Protection from misalignment, shock, and vibration:

PARALLEL:The S-Flex coupling ac-cepts up to 0.813mm ofparallel misalignmentwithout wear. The flex-ible coupling sleeve mini-mizes the radial loadsimposed on equipmentbearings, a problemcommonly associatedwith parallel misalign-ment.

ANGULAR:The flexing action of theelastomeric sleeve andthe locking feature of themating teeth allows theS-Flex coupling to effec-tively handle angularmisalignment up to 1°.

AXIAL:The S-Flex couplingscan be used in applica-tions which require a lim-ited amount of shaft en-float without transferringthrust loads to equip-ment bearings. Axialmovement of approxi-mately 3.175mm ac-cepted.

TORSIONAL:S-Flex couplings effec-tively dampen torsionalshock and vibration toprotect connectedequipment. The EPDMand Neoprene sleeveshave torsional wind-upflexibility of 15° at theirrated torque. Hytrel pro-vides 7° wind-up.

SHAFT COUPLINGS Service Factor OverviewGrid

Couplings Reduce Vibration, Absorb Shock andCompensate for Misalignment.

The Power of Torsional DampingThe Lovejoy G-Type Flexible Grid Coupling reduces vibra-tion by as much as 30%, and cushions shock loads tosafeguard your driving and driven equipment. The flex-ible nature of the spring-like grid absorbs impact energyby spreading it out over time, thus reducing the magni-tude of the peak loads. This is possible because of theprogressive contact that occurs between the curved pro-file of the hub teeth and the flexible grid. Therefore, as theload increases, more of the tooth comes into contact withthe grid, thus supplying superior protection and supremeperformance.

Lovejoy G-Type Flexible Grid Couplings are designed forversatility. Common hubs and grids are used within agiven size range for both horizontal and vertical split covermodels. Grid installation and replacement is a �snap� atonly a fraction of the complete coupling cost.

Benefits of the Grid Coupling include:� Our G2000 Series Tapered Grid coupling is fully interchangeable with industry standards.� Quick installation and easy maintenance reduces labor and downtime costs.� Torsionally flexible and resilient-reduces vibration, plus cushions shock and impact loads.� Versatile stock components can be used with either horizontal or vertical covers. Cover fasteners available in either Metric or Imperial sizes.� High tensile, shot-peened alloy steel grids and preci-

sion machined hubs ensure superior performance and long life.

Top Quality ManufacturingMade from a high tensile alloy steel, the grid spring iscarefully formed to shape, then hardened and temperedunder controlled conditions. Next, the grids are shot-peened, compressing the surface molecules and leavinga residually stressed surface. This process creates astronger surface in compression.

Any load applied on the coupling in operation must firstsurmount the compressive forces created by peeningbefore the tensile stress reaches the grid. This provides adramatic increase in rating over other coupling types, in-creases reserve strength for longer life and may permitselection of a smaller coupling, thus reducing cost.

The Lovejoy Grid spring/hub tooth arrangement has beenspecifically designed for optimum performance and su-preme reliability. Not only does the hub tooth profile per-mit progressive loading under torsional shock conditions,but unique root radii are incorporated to significantly im-prove the fatigue life of the teeth.

FULL SPACER DESIGN� Ideal for pump applications because drop-out section allows for pump servicing.

Misalignment Capacity:

Parallel: The movement of thegrid in the hub grooves accom-modates parallel misalignmentand still permits full functioningof the grid-groove action indamping out shock and vibra-tion.

Angular: Under angular mis-alignment, the grid-groove de-sign permits a rocking and slid-ing action of the grid and hubswithout any loss of powerthrough the resilient grid.

Axial: End float is permittedfor both driving and drivenmembers because the gridslides freely in the grooves.

Centaflex Coupling Design Types


15dMotion Technology


n Simple, compact, smooth-face

design.

n Low weight, low moment of

inertia.

n High performance, high-speed

range, large bores permitted,

ruptureproof.

n Large angle of twist with

progressive characteristic

curve (approx. 6° - 8° at

nominal torque).

n High elasticity and consider-

able flexibility in any direction

(radial, axial, angular) with low

counter forces on shafts and

bearings. The shafts do not,

therefore, have to be aligned

accurately.

n The action of the Centaflex

coupling is shock and vibra-

tion absorbing.

n The torque is transmitted

absolutely free from play,

uniformly, free from noise, and

electrically insulating.

n The coupling requires no

maintenance, the rubber parts

suffer no wear, providing long

useful life with no dirt pro-

duced by rubber particles.

n The rubber element is air

flushed all-round; the heat

generated is easily conducted

away and the rubber element

remains cool.

n The rubber element can easily

be fitted and dismantled

without the use of special tools

or tension bands.

n The coupling can be very

easily aligned, relying on line

of sight or with the aid of a

straight edge, without any

special templates or gauges.

n The elements can be disman-

tled transversely without any

axial displacement.

n By slackening the radial

screws, the drive can be easily

separated and rotated without

dismantling.

n No axial reaction forces are

imposed on shafts and bear-

ings due to the transmission of

torque.

n Rubber elements are available

in various shore hardness

grades. This permits variation

of the torsional stiffness within

wide limits an dits adaptation

to the vibrational requirements

of each drive system.

n The rubber elements are

available in various materials:

Standard: Natural Rubber

Special Materials: Perbunan,

Neoprene, etc.

CENTAFLEX(THE COUPLING WITH THE 5-WAY-FLEX)

Every good elastic coupling has 4-way flexibility:

1. Torsional elasticity

2. Radial flexibility

3. Axial flexibility

4. Angular flexibility

In addition, the Centaflex is uniquely flexible in application, i.e. capable of modification and adaption;

Centaflex therefore has 5-way flexibility.

The Lovejoy Miniature flexible couplings have provento be particularly suitable in all light duty and precisionapplications. The design objective of a Miniature flexiblecoupling is to transmit torque loads without permanentdistortion or damage and without imposing undue bend-ing or radial loads upon the driver or driven components.The specific characteristics of each application determinethe proper flexible coupling to use.

Characteristics such as torsional stiffness, absorption ofvibration, isolation, backlash, tolerance to chemicals andcorrosion and uniform velocity should all be considered inthe coupling selection. Typical operational requirementsfor Miniature flexible couplings include light duty, torqueratings less than 50 in-lbs., torsional rigidity, low inertia,constant velocity, low radial stiffness, zero backlash, cor-rosion resistance, and the capability of cyclic (repeatedstart/stop/reverse) activity.

Applications that normally use Miniature flexible couplingshave a fractional electrical motor driver. Examples of thesetypes of applications include shaft encoders, resolvers, allforms of servo devices, linear and ball screw actuators,robots, step motors, light duty pumps and metering de-vices, plotters, positioning tables, computers, and radar.

Lovejoy offers four distinct coupling designs; Beam,Oldham, Mini Soft, and Jaw. These designs provide awide range of alternatives in addressing fractional electricmotor applications.

Beam CouplingThe Lovejoy Beam Miniature cou-pling is formed from one piece ofaluminum rod. After sizing, boringand installing the clamping mecha-nism or set screw, the final step isto cut a spiral flexure or �coil� inthe coupling. The result is truly aflexible coupling that transmitstorque through the flexure while accommodating angular,parallel and axial misalignment.The Beam coupling provides zero backlash, high tor-sional stiffness, and high speed capability while being

Lovejoy

very lightweight. Its one piece construction makes in-stallation simple and the construction provides for heatand chemical resistance in environments that would beharmful to elastomeric couplings.

Oldham CouplingThe Lovejoy Oldham coupling is aprecision engineered, torsionallystiff, three part coupling suitablefor a great many applicationsranging from incremental controlof fluid valves to highly dynamicdrives in a closed loop servo sys-tem. It accommodates misalign-ment mechanically through a floating disc that engagestenons machined out of the hubs. As the coupling ro-tates, the disc aligns with each hub alternately to anextent demanded by the alignment error. The principleof operation should not be confused with that of theJaw coupling which accommodates misalignmentthrough compression of an elastomer.

Mini Soft CouplingThe Mini Soft Miniature coupling fromLovejoy provides protection from mis-alignment, vibration, and shock loads.The simple design of the couplingensures ease of assembly, installationand reliable performance. No specialtools are needed for installation orremoval. No lubrication is needed andonce installed and aligned correctly,no maintenance is required.

The Mini Soft Miniature coupling design is comprisedof three pads. Two hubs with internal teeth that engagean elastomeric flexible center with external teeth. Eachhub is attached to the respective shaft of the driver anddriven and torque is transmitted across the hubsthrough the center. Misalignment and torsional shockloads are absorbed by shear deflection in the centerelement. The shear characteristic of the coupling is verywell suited to absorb impact.

Jaw Type CouplingThe interlocking jaws of the three partLovejoy Miniature Jaw coupling pro-vide positive engagement resultingin great strength because of the largearea of contact of the elastomer withthe jaws.This Miniature coupling pro-vides �fail safe� operations and is theonly coupling that will continue torun, even if the elastomer center fails,through the metal to metal jaw contact that will con-tinue to transmit torque.

The figures in heavier type are for standard motor speeds. All these power ratings are calculated at constant torque.For speeds below 100 rev/ min and intermediate speeds use nominal torque ratings.

1. Service FactorDetermine the required service factor from Table 1 below.

2. Design PowerMultiply tne normal running power by the service factor. Thisgives Design Power which is used as a basis for selecting thecoupling.

3. Coupling SizeRefer to Table 2 and from the appropriate speed read acrossuntil a power greater than that required is found. The size ofTyre-flex coupling required is given in that column.

4. Bore SizeCheck from Table 3 that selected coupling can accomodaterequired bores.

BSC Part Number ExampleTL 65 1 C

Torque Limiter Size No of Disc Springs Coupling Type

The Torque Limiter is a protective device that limits the torque transmitted in a drive system byslipping when the torque demand exceeds a preset value as a result of shock loads, overloads,or machine jams. It automatically reengages when the overload is removed. No resetting isrequired. Torque Limiters prevent machine damage and eliminate costly downtime.

Torque Limiters utilize spring loaded friction surfaces for their operation and slip torque is presetby adjustment of the spring force using the adjustment nut or bolts.

Torque Limiters can be used with a sprocket, gear, sheave, or flange plate as the center member damaged between two friction facings.

The Torque Limiter ratings are realistic and consistent with optimum spring loads and face pressures that permit longer slip time, maintain re-engagement at preset torque, and providelong lasting protection. This is an important advantage over the shear-pin mechanism whichserves only as a one-shot remedy.

Torque LimitersSelection & Center Member

SELECTION

CENTER MEMBER

1. Determine the required slip torque from the loading conditions or from the design strength ofthe machine. If the loading conditions of the machine are unknown, set the required sliptorque of the torque limiter to 1.52 times the torque that the motor produces on the shaftwhere the torque limiter is mounted.

2. Select a torque limiter which has enough torque range and bore range.

3. Determine the proper bushing length from the thickness of the center member to be insertedbetween the friction facings.

Always choose the largest bushing which does not exceed the width of the center member.Maximum thickness of the center member is shown as “S max.” in the dimension table.

1. The center member should be machined on its rubbing surface to obtain the rated torque andbe flat, parallel, square with bore, and free from rust, scale and oil. Surface finish recom-mended is 3S~6S (63 microinches finish).

If the center member is not in accordance with these specifications, the slip torque will beerratic.

2. Bore of the center member to be machined is shown in the table below. Also, minimum num-ber of sprocket teeth to be used and bushing length to be chosen are listed in the table.

TORQUE SETTINGTorque setting of the torque limiter is achieved by tightening or loosening the adjustment boltsand/or the adjustment nut. For torque adjustment of TL50 through TL89, an adjustment nut isprovided, and for TL127 through TL20, adjustment bolts are provided. The torque setting can be made after mounting the torque liminter on the shaft. The procedure is as follows:

For TL50 through TL89:

First, rotate the adjustment nut tightly by hand so that the disk spring fits the plate. Then tenta-tively tighten the nut by 60° with a wrench.

For TL127 through TL20:

First, rotate the nut for fixing the disk spring to the plate, and then tighten each adjustment boltby about 60 degrees.

Then, if the torque limiter slips under normal loading conditions, tighten the nut (for TL50~TL82)or the bolts (for TL127~TL20) gradually until the torque limiter stops slipping. Always tighten (orloosen) the bolts equally. Try this adjustment several times to find the proper torque setting forthe machine. For your guidance, the chart on the next page shows the relation between theeffective rotated angle and preset torque.

For precise torque setting, run-in of the torque limiter is recommended, for example, 500 revolu-tions at 50~60 rpm with a rotated angle of 45° of the adjustment nut or the bolts.

2. Check parallel alignment by placing a straight edge acrossthe two hubs and measuring the maximum offset at vari-ous points around the periphery of the hubs without rotat-ing the coupling. If the maximum offset exceeds the paral-lel value in Table 3, realign the shafts.

3. Check angular alignment with a micrometer or caliper.Measure the “X” dimension from one hub to the other atintervals around the hubs. Determine the maximum andthe minimum dimensions without rotating the coupling. Thedifference of these two measurements must be less thanthe angular value in Table 3. If a correction is necessary,recheck the parallel alignment.

4. Position the spacer between the two hubs with collars looseon the hub or spacer. Install the snap-wrap spiders andfasten collars with cap screws. Proceed to Step 3.

2b. For RRC Type - Style 4.

1. Slide one adaptor hub onto each shaft, using keys whererequired. Position the hubs on the shafts to achieve a spacergap as in Figure 5. It is usally best to have an equal lengthof shaft extending into each hub. Tighten both hubs withthe set screw torque from Table 1.

2. Install the spacer section between the two hubs. The spacersection includes two jaw rings, the cushions, and a collar.Fasten the spacer section to the adaptor hubs with the axialmounting screws and torque them to 68-76 ft-lbs.

3. Slide collar off jaw ring and set on the adaptor hub. Somecushions at the bottom side of the coupling can fall outand may be set aside while checking shaft alignment.

4. Check parallel alignment by placing a straight edge acrossthe two hubs and measuring the maximum offset at vari-ous points around the periphery of the hubs without rotat-ing the coupling. If the maximum offset exceeds the paral-lel value in Table 3, realign the shafts.

5. Check angular alignment with a micrometer or caliper.Measure the “X” dimension from one hub to the other atintervals around the hubs. Determine the maximum andthe minimum dimensions without rotating the coupling.

The difference of these two measurements must be lessthan the angular value in Table 3. If a correction is neces-sary, recheck the parallel alignment.

6. Reinstall the cushions and fasten the collar with cap screws.Proceed to Step 3.

C. LC Type2c. For LC Type - Styles 1 and 2

1. Slide one hub onto each shaft using the keys where re-quired. Position the hubs on the shafts to approximatelyachieve the “G” dimension shown in Table 2.

It is usually best to have an equal length of shaft extendinginto each hub. Tighten both hubs in their final positionswith set screw torque from Table 1. Slide the collar to theedge of the hub and do not install the spider at this time.

2. Check parallel alignment by placing a straight edge acrossthe two hubs and measuring the maximum offset at vari-

A. L, AL, C and H Types

Jaw hubs and elastomers come in many sizes and types. First,determine the size and type of components being used. Re-move all components from their boxes and loosely assemblethe coupling on any convenient surface. Also check maximumRPM values in Table 2 against operating speed.

1. Inspect all coupling components and remove any protec-tive coatings or lubricants from bores, mating surfaces, andfasteners. Remove any existing burrs, etc., from the shafts.

2. Slide one coupling hub onto each shaft, using keys whererequired. Keys should fit snugly.

3. Position the hubs on the shafts to approximately achievethe “G” dimension shown in Table 2. It is usually best tohave any equal length of shaft extending into each hub.Tighten one hub in its final position.

For style 1 or style 2, if possible, slide the other hub farenough away to install elastomer. If hub cannot be slid back,or if “blind” assembly, tighten second hub on shaft andbring equipment together.

For style 3, tighten hubs on shafts, do not install cushionsand collar at this time. Tighten setscrews to the appropri-ate value shown in Table 1.

4. Check parallel alignment by placing a straight edge acrossthe two coupling hubs, and measuring the maximum off-set at various points around the periphery of the couplingwithout rotating the coupling. If the maximum offset exceedsthe figure shown under “Parallel” in Table 2, realign theshafts.

5. Check angular alignment with a micrometer, vernier, orcaliper. Measure “X” from one hub to the other at intervalsaround the coupling. Determine the maximum and mini-mum dimensions without rotating the coupling, the differ-ence of these two measurements must be less than theAngular value in Table 2. If a correction is necessary, besure to recheck the parallel alignment.

B. RES,RC, and LC TypesDetermine the size and type of coupling being used. also checkmaximum RPM values in Tables 2 and 3, against operatingspeed. Remove all components from their boxes and looselyassemble the coupling on any convenient surface.

Inspect all coupling components and remove any protec-tive coatings or lubricants from bores, mating surfaces, andfasteners. Remove any existing burrs from the shafts.

Step 2.

Use appropriate section for the type of coupling assembly.

2a. For RRS Type - Styles 1, 2 and 3

1. Slide one hub onto each shaft, using keys where required.Position the hubs on the shafts to achieve spacer gap as inFigures 3 and 4. It is usually best to have an equal lengthof shaft extending into each hub. Line up the jaws of bothhubs and tighten them with set screw torque from Table 1

ous points around the periphery of the hubs without rotat-ing the coupling. If the maximum offset exceeds the paral-lel value under NBR in Table 2, realign the shafts.

3. Check angular alignment with a micrometer or caliper.Measure the “X” dimension from one hub to the other atintervals around the hubs. Refer to Figures 1 and 2 forStyles 1 and 2, respectively. Determine the maximum and

the minimum dimensions without rotating the coupling. Thedifference of these two measurements must be less thanthe angular value under NBR in Table 2. If a correction isnecessary, recheck the parallel alignment.

4. Install the snap-wrap spider and fasten the collar with capscrews. Proceed to Step 3.

Note:Install coupling guards per OSHA or ASME 815.1 require-ments.
