FUNCTION:Multiplate slip clutches control torque for intermittent, continuous, or overload slip. It will drive in both directions, slip when the torque setting is reached, and resume driving as the load is reduced. These clutches are excellent as continuous or intermittent drag brakes, protection against overloads, for “soft starts,” slip at the end of a stroke, as friction hinges, for screwing on container caps, etc.
CONSTRUCTION:The clutch consists of two assemblies: a cartridge and a housing (see cutaway above). The cartridge is set-screwed or keyed to the input shaft. The housing is either set-screwed or keyed to the output shaft or, as shown, is attached to the output gear or pulley with a bronze bearing to allow relative motion between the input shaft and the output gear/pulley. Torque is transmitted from the flats on the hub to the mating flats on the inner plates, through the friction pads to the outer plates, through the torque pins to the housing and the output gear/pulley. The torque level is controlled by compressing the springs with the adjusting nut. For a fixed torque clutch, a collar is attached to the hub in a fixed position instead of the adjusting nut. In operation, either the input shaft or the housing can be the input member, with the other member being driven.
CAPACITY:The clutch capacity as noted in the catalog is based on continuous operation at 50 rpm for over 25 million cycles. Torque, rpm, duty cycle and life are interdependent. A reduction of any of these will allow an increase in any other. Running at 25 rpm will allow twice the torque, or running for only 10% of the cycle will allow higher rpm, etc.The limit is based on heat buildup measured in watts: English Unit Watts = Torque (lbf) x rpm x 0.0118 x % Duty CycleMetric Unit Watts = Torque (Nm) x rpm x 0.104 x % Duty Cycle
For typical applications, see examples on page 13-4.

SPRING-WRAPPED SLIP CLUTCHES
FEATURES:Long life under continuous slip conditions.Unidirectional or bidirectional operation.Same or different clockwise and counterclockwise torques.Precise and stable limit torque calibration (range: 1.0 to 480 ozf in.).Same torque at breakaway as at high slip velocities.Mounting provisions for gear, sprocket or pulley.Corrosion-resistant materials.
APPLICATIONS:Tension control of film or tape drivesTransmission overload protection
SPECIAL DESIGNS:
The standard line of slip elements provides a wide selection of limit torques, sizes and coupling arrangements. In addition, our engineers will modify designs to meet your specific requirements in such areas as: Configuration Driving arrangement Limit torques from a fraction of an ozf in. to several lbf ft. Calibration of torque to a tolerance of ± 5% Different limit torques for the two directions of rotation Spring windup and limit torque combination. The spring action of the slip element is useful for tensioning of tape and prevention of slack loops.
* Stock units are calibrated with equal clockwise and counterclockwise slip torques corresponding to the tabulated Upper Limit Torques. Other torques are readily available from full, down to 1/8 of the Upper Limit Torque for each model. Torque values are independent of each other for clockwise and counterclockwise rotation, and may be specified the same or different for the two directions.
** All clutches in this series have a pilot diameter “K” and three tapped holes “N” for mounting a gear, sprocket or pulley on the input hub. Screw penetration into the clutch housing must not exceed the depth specified in column “N”. Concentricity of pilot diameter “K” to bore “C” is .001 T.I.R. max.
All slip clutches are designed for long life under continuous slip conditions. The useful life of these elements is a function of the transmitted torque and slip speed.
The life of the slip couplings & clutches is defined as the number of hours of continuous slip required to cause a deviation of 10% from the initial calibrated torque value. Extensive life tests have been performed on a number of standard units. The “Life Expectancy Curves” are designed for approximating the life span of standard slip clutches and couplings.

SPRING-WRAPPED SLIP CLUTCHES
EXAMPLE: If a slip clutch is to provide a torque limit of 50 ozf in. at a continuous slip speed of 100 rpm for 500 hours, the smallest item which can be calibrated is from the S9940Y–SWC15A.. series.
The upper limit torque for this unit is 80 ozf in.
Limit Torque Ratio = Required TorqueUpper Limit Torque
= 50/80 = 0.63
From “Life Expectancy Curves” 100 rpm & 0.63 ratio:
Life = 2,800,000 Rev =2,800,000 Rev
100 Rev / Min. x 60 Min. / Hour= 466.7 Hrs.
The 466.7 hours life value is less than desired 500 hours.The next larger slip clutch belongs to the S9940Y–SWC18A series.The upper limit torque for this unit is 120 ozf in.
Limit Torque Ratio = 50/120 = 0.42
From “Life Expectancy Curves” for 100 rpm & 0.42 ratio:
Life = 4,800,000 Rev = 4,800,000 Rev100 Rev / Min. x 60 Min. / Hour
= 800 Hrs.
A S9940Y–SWC18A.. series clutch will provide the desired life.

SPRING-WRAPPED SLIP COUPLINGS
FEATURES:Long life under continuous slip conditions.Unidirectional or bidirectional operation.Same or different clockwise and counterclockwise torques.Precise and stable limit torque calibration (range: 1/2 to 88 ozf in.).Same torque at breakaway as at high slip velocities.Corrosion-resistant materials.
APPLICATIONS:Tension control of film or tapeTransmission overload protectionFriction loads for testing components
RECOMMENDED MOUNTING PROCEDURE:
Coupling is slipped over one shaft and applicable screws tightened.Second shaft is inserted into other end of coupling.Pull loose end of coupling back about .02 in. and tighten applicable screws.
The slip coupling serves as a torque limiter as well as a coupling for two colinear shafts. This coupling is equipped with hubs at both ends for pinning to the two shafts. When the load exceeds the limit torque of a slip coupling, the two shafts rotate relative to each other at the full limit torque. The standard coupling is designed to operate with 3° angular or linear misalignments of up to .010 in. between the two shafts. The mounting hole diameters of the slip couplings can differ for the two ends, so that different diameters of “in-line” shafts can be coupled together.
* Stock units are calibrated with equal clockwise and counterclockwise slip torques corresponding to the tabulated Upper Limit Torques. Other torques are readily available from full, down to 1/8 of the Upper Limit Torque for each model. Torque values are independent of each other for clockwise and counterclockwise rotation, and may be specified the same or different for the directions.
This series of slip couplings is designed for long life under continuous slip conditions. The useful life of these elements is a function of the transmitted torque and slip speed.

ADVANTAGES:No electricityNo breakaway torqueConstant torque independent of shaft (rotor) speedNo contacting or wearing partsNo friction elements – same smooth torque year after yearNo magnetic particles to leak or contaminate end productOperable in some of the most difficult environmentsBrake (with shaft) and clutch (with hollow shaft) availableCustom designs available
APPLICATIONS:Fig. 1 As a CouplingThis is for load protection or torque limiting. The coupling style unit is directly connected to a motor and turns at the same speed as the motor until the torque is reached. At this point it will slip and still generate the maximum torque.
Fig. 2 As a ClutchThe unit is connected to a motor by a timingbelt or gear. The housing is driven and theshaft is the output end.
Fig. 3 As a Payout BrakeBrake is stationary and the reel or materialis fitted to the output shaft. The tension onthe material will vary with the diameter.
HOW THEY OPERATE:For Maximum TorqueAll important internal clearances are ground to tolerances of less than .001 in. (0.025 mm). Magnet assemblies surround hysteresis assembly. When like poles face each other, they produce maximum magnetic saturation of the hysteresis disc, forcing lines of flux to travel circumferentially through the hysteresis disc.
For Minimum TorqueWhen opposite poles face each other they produce minimum saturation of the hysteresis disc. The lines of flux travel through the hysteresis disc.
Combinations of adjustment angles between the two extremesgive infinite adjustability. Because there are no contacting surfaces, the setting can be maintained indefinitely.

OPERATING CURVES
HOW TO USE THE CURVES:Find the slip rpm on the X-axis and the torque on the Y-axis. Notice the areas that represent safe, continuous duty; intermittent duty, such as five minutes on, five minutes off; and the area which is not recommended. Operating above that line for any period of time will cause overheating and possible damage to the unit.

TECHNICAL INFORMATION
FEATURES:Torque proportional to input current. Torque virtually independent of slip speed.Smooth stable, noise-free operation.Long-life no-wearing components.Maintenance-free.Infinitely adjustable.
APPLICATIONS:Tensioning of wire, cable, films, paper, etc.Positioning of fuel flow controls, film processorsBraking for motors and dereelingLoad simulation for motor testing, fuse testing, etc.
OPTIONS:Nonstandard coil voltages Special mounting configurationsModified shafts
Hysteresis clutches provide an efficient, smooth, electrically controllable link between a motor and a load. While pre-senting integral ball bearing supported input and output shafts, the clutch features a field (electromagnet) assembly that is prevented from rotating by fixing to a bulkhead. When the coil is energized, the input and output shafts are coupled by magnetic fluxes, thus driving the load. The torque transmitted is proportional to the current supplied to the device.
TORQUE AS A FUNCTION OF INPUT CURRENT:
When a field setting is approached from zero current, it will produce less torque than if approached from prior current because of residual magnetism. Accurate and repeatable torque outputs are delivered when the setting is approached from the same direction.

TECHNICAL INFORMATION
APPLICATION EXAMPLE:To select a brake to tension a 7-inch (178 mm) diameter pay-off reel in a system requiring total (web or strand) tension of 2 lbf (8.9 N) and a process speed of 600 FPM.
BRAKE TORQUE (T) = Force (F) X Radius (D/2) T = 2 lbf (8.9 N) X 3.5 in. (88.9 mm) = 7 lbf in. (791 Nmm) or T = 32 ozf X 3.5 in. (88.9 mm) = 112 ozf in.
SLIP SPEED (rpm) = linear velocity (V) (in./min.) / circumference (in.) or linear velocity (V) (mm/min.) /circumference (mm) rpm = 600 ft./min. X 12 / (π X 7 in.) or (183 m/min. X 1000) / (π X 178 mm) rpm = 327
ENERGY (W) = Energy Dissipation requirement is calculated using basic DISSIPATION horsepower formula X 746 watts/hp W = (T (lbf in.) X rpm / 63025) X 746 or (T (Nmm) X rpm / 7145221) X 746 W = (7 lbf in. X 327 rpm / 63025) X 746 = 27 watts or (791 Nmm X 327 rpm / 7145221) X 746 = 27 watts

HORSEPOWER
Quick Check: The curves to the leftcan be used as a quick check to verify the kinetic power calculation. Simply locate the required torque on the vertical axis, move horizontally until you intersect the appropriate speed line, and then read vertically (up or down) to obtain the resulting watts or horsepower.
Selection: From the data on the fol-lowing pages it can be seen that an S90HYB-120024 Hysteresis Brake which has a rated torque of 120 ozf in. (847 Nmm), a maximum speed capability of 12000 rpm, and an energy dissipation ca-pability of 75 watts continuous, would be the proper selection for this application.
Note: In a clutch application, slip speed is the difference in rotational speed between the input and output members of the clutch assembly. In the above example, tensioning was being accom-plished with a clutch inserted between a take-up reel and a motor driving at 500 rpm. The actual slip used to compute the energy dissipation requirements would be 500 rpm (clutch input speed) - 327 rpm (clutch output speed = 173 rpm). This dif-ference in speed would obviously impact the result for energy dissipation.

Determine clutch or brake torque valueWith the inertia value calculated, determine the torque requirement for the function.
A) For Overrunning and Start-Stop(random start-stop)
Where:T = Torque required from wrap spring, lbf in.WR2 = load inertia, lbf in.2 rpm = shaft speed at clutch locationt = time to engagement (.003 for clutch), sec.
Frictional (drag) torque is the torquenecessary to overcome static friction. It may be measured by a spring-scale or by dead-weights, applied to a known moment arm so gradually as to make inertia negligible. It is that torque found just sufficient to induce motion.
Calculate load inertia (WR2)Use the inertia chart to determine the inertia of the application components. To determine WR2
of a given shaft or disc, multiply the WR2 from the chart by the length of shaft or thickness of disc in inches.
NOTE: For hollow shafts, subtract WR2 of the I.D. from the WR2 of the O.D. and multiply by length.
In order to calculate the inertias of components which are made of material other than steel, use the multipliers found in the conversion chart (below) to establish the inertias of these components.

CHARACTERISTICS OF DISENGAGEMENTControl collar release time (ADT) is affected somewhat by speed, load, and the operational performance. The electrical circuit, however, has a major impact on the clutch disengagement performance. Voltage transients and bleed down time should be minimized. The optimum suppression network for an application using the clutch is represented
ShaftFlange
HubControlCollar
by circuit C which incorporates a 1N4004 series diode and a 12V zener. Omitting the zener (circuit B) would result in a less expensive circuit but at the expense of minor decrease in performance. Circuit A represents the quickest disengagement time but provides no protection for voltage transients.
MAGNETICALLY ACTUATED CLUTCHESPrinciples of Operation:
Clutch OperationThe inside diameterof the spring is larger than the outside diameter of the shaft hub. One end of the spring (control tang) is fastened to the control collar (or armature). When the coil is de-energized, the hubs rotate independently of each other. The free hub (affixed to the spring), the spring, and the collar rotate as a unit. The opposing shaft hub is not fastened to the spring and rotates as another unit. The coil housing is stationary and piloted on the shaft bearing. A ground pin placed in the retaining tab secures the coil hous-ing from rotating.
When the coil is energized, the control collar is pulled and heldagainst the shaft flange. The mo-mentary relative motion between spring and hubs "wraps" the spring, coupling the two hubs posi-tively. All torque is transmitted through the wrapped spring. Magnetic force is only necessary to maintain a tight spring grip for total torque transfer.

These units are positive drive slip clutches which provide accurate overload protection in many mechanical power transmission systems. When a jam-up or excess over-load occurs, these units disengage motor drives.
When load exceeds the rating determined by precision tem-pered torque springs, the unit's drive key pivots out of a slot to disengage the slip clutch. Once the overload is removed and speed reduced, the unit resets itself automatically.
Steel springs within the unit force metal slides against each side of a hardened cast steel pawl, holding it rigid with one end seated in a detent on the outer drive housing.
During normal machine operation, power transfers into the central assembly through the rigidly held pawl and then rotates the outer drive housing and the driven shaft to which it is connected. If a jam-up or some other malfunction causes an unacceptable load to occur, excessive torque on the pawl overpowers the springs and the pawl rotates out of its detent. Thus, the central assembly is disconnected from the outer drive housing.
Once the overload is removed and speed reduced, the torque springs automatically expand to force the pawlback in its detent. This automatic resetting action engagesyour drive shaft and puts the entire drive system back intomotion at its original angular position.
Instant Actuation
Fast, Automatic Resetting
The Actuating Pin Assembly is a simple pin which is forced out radially from the the main body when overload occurs. When using this option, it is important to note that the housing or external mounting hub end of the unit is the power source or input end. This part of the unit must continue to rotate for the extended pin to contact a customer-supplied limit switch for shutdown or warning.

MAGNETIC PARTICLE CLUTCHES & BRAKES
FEATURES:Magnetic engagement without movement ofmechanical parts.Smooth and silent.No backlash.Nearly linear torque vs. current.No friction surface to wear out.Ultrafast response.Low output inertia.High torque-to-size ratio.Infinitely adjustable torque.
APPLICATIONS:TensioningStepping and IndexingOverload ProtectionMotor TestingControlled Start / Stop
HOW THE UNITS WORK: The output disk/shaft assembly does not touch the housing. The gap in between is filled with a fine, dry stainless steel powder. The powder is free flowing, until a magnetic field is applied from the stationary coil. The powder particles form chains along the magnetic field lines, linking the disk to the housing. The torque is proportional to the magnetic field and, therefore, to the applied D.C. input current. Output torque is controlled by varying the D.C. input current. The torque vs. current curve is essentially linear, with a slight "S" shape.
While the input torque is less than the output torque, the brake or clutch won't slip. For brakes, the output shaft won't rotate. For clutches, the input shaft will be coupled to the output shaft, with no slip.
When the input torque is increased, the brake or clutch will slip smoothly at the torque level set by the coil input current. Output torque is independent of slip rpm.
NOTE: See Accessories and Power Supplies on page 13-50 thru 13-53.

FOLLOWER ARM POTENTIOMETER
Catalog Number
INCH COMPONENT
Supplied With
S90MPF-126Shaft Clamp, 12 in. Arm &
6 ft. Cable Included
DESCRIPTION: MAINTAIN CONSTANT TENSION - The follower arm potentiometer is used to maintain constant tension when using a brake for producing unwind (payout) tension, or when using a clutch for rewind tension.
APPLICATION:The arm rides on the roll, measuring the roll diameter. As the roll size decreases, the armmoves downward, rotating the potentiometer shaft. The power supply current automaticallydecreases, which decreases the brake (or clutch) torque to maintain constant tension.
SPECIFICATIONS: Resistance: 500 Ω Electrical Angle: 65° Mechanical Angle: 360° (No Stops) Maximum Drag Torque: 4 ozf in.

ULTRASONIC SENSOR
Catalog Number
INCH COMPONENT
S90MPU-BIP67
DESCRIPTION: MAINTAIN CONSTANT TENSION - The Ultrasonic Sensor is used for maintaining constant tension when using a brake for producing unwind (payout) tension, or when using a clutch for rewind tension. When the target is within range, the LED Status Indicator glows continuously.
MATERIAL:Housing - Polyester
VOLTAGE:24V DC
OPERATING TEMPERATURE:+14°F to +140°F (-10°C to 60°C)
APPLICATION: The sensor measures the diameter of the roll and sends a 0 – 10V DC signal to the power supply. Torque is automatically varied as roll size changes, to keep tension constant. The sensor measures distances by sending an ultrasonic pulse of sound, and then measuring the time for the return echo pulse.
SPECIFICATIONS: Power Input: 15 – 30V DC, 35 mA Max. * Range: 3.9 – 39.3 in.∆ Output Resolution: 0 – 10V DC Repeatability: .02 (0.5 mm) Resolution: .012 (0.3 mm)
