SHAFTLOC®

PATENTED

A SUPERIOR WAY TO FASTEN ROTATING COMPONENTSExcelling because of its simplicity, it contains all structural features in only two parts. This new development is the Shaftloc®

– a patented device (United States Patent No. 5,067,846 and No. 6,000,875), – manufactured and marketed by Stock Drive Products.

The usefulness of wedges and inclined surfaces for the lifting of heavy loads has been well-known for centuries.Similarly, the usefulness of tapered, conical surfaces has also been appreciated; in this case, for their ability to produce large forces.

An example of such an application is the use of a tapered cylindrical split bushing (see illustration) to fasten a rotating component to a shaft. The axial force, which results from tightening the bolts, is translated into amplified radial forces that close the split bushing.

In this way, fastening of the component to the shaft is achieved. A disadvantage of this particular method is that the component must have a tapered bore.

A modification of this method, so that it can be used to fasten components with cylindrical bores, involves the use of a transition plate which contains the tapered bore.

However, the Shaftloc® design is the ULTIMATE in fastening methods for the following reasons:

Shaftloc® has only two parts:A slotted outer sleeve and a slotted inner sleeve, both of which have hexagonal heads. The outer sleeve is cylindrical on its outside diameter, and threaded on its inside diameter. Conversely, the inner sleeve is threaded on its outside diameter, and cylindrical on its inside diameter. The thread is unique in that it is not symmetrical and that it creates a continuous inclined surface.

How Shaftloc® works:The shallow angle of the thread produces large amplifications of forces, resulting in substantial torque transmission capability between the component and the shaft.

Style 1: Double-EndedWhen the two sleeves are threaded into each other with a component placed between them, tightening the sleeves will cause the outer one to expand and the inner one to contract. Style 2: Single-EndedWhen the two sleeves are threaded into each other and slipped into the component, tightening the sleeves will cause the outer one to expand and the inner one to contract.

Style 3: Shaftloc® M-TypeTwo-piece construction consists of a slotted sleeve and a nut, both of hexagonal shape. Used as a locking device for rigidly mounting mechanical components on a shaft. Tightening the nut next to the component causes the slotted sleeve to contract by gripping the shaft and clamping the part to the sleeve at the same time.

Style 4: Shaftloc® A-TypeTwo-piece construction consists of a bolt and a nut which becomes a vibration-resistant fastener when the nut is tightened to embrace the component mounted to it. The two-piece unit uses the wedging action between the shallow thread inclines of the nut and bolt when the nut is tightened against the component mounted on the bolt.

PATENTEDSELF-LOCKINGVIBRATION-RESISTANTNONMARRING OF SHAFTINSTALLED WITH STANDARD TOOLSREUSABLE

MATERIAL:416 Stainless Steel, Passivated

SPECIFICATIONS:Used as a locking device for rigidly mountingmechanical components onto a shaft.Due to its asymmetric thread geometry,a large radial clamping force is producedwhen the nut is tightened. It is a precision,dynamically balanced product suitable forhigh-speed applications. This simpletwo-piece keyless fastener can beinstalled within seconds, reducingassembly costs. Tightening the nutcauses the slotted sleeve to contract,gripping the shaft and clamping thepart to the sleeve at the same time.Keyways and screws are now obsolete; can be installed on shafts with existingkeyways.

PATENTEDSELF-LOCKINGVIBRATION-RESISTANTINSTALLED WITH STANDARD TOOLSREUSABLE

MATERIAL: 416 Stainless Steel, Passivated

SPECIFICATIONS: These vibration-resistant fasteners employ asymmetric threads to self-lock. The two-piece unit uses the wedging action between the shallow thread inclines of the nut and bolt for self-locking when the nut encounters resistance. The nut turns freely until it contacts parts being clamped together and additional turns wedge them into a locked and vibration-resistant condition.

PRESSURE LOCKING HUB CONNECTORS

NO WEAR OR STRESS ON COMPONENTEASY TO USESPACE SAVER

MATERIAL: Hardened Steel

SPECIFICATIONS: These connectors are designed for fast and accurate repositioning of the hub. It has just one screw for pressurizing in radial position. No space is used along the shaft for mounting tools. They are made up of a double-walled sleeve and flange filled with a pressure medium. Pressure screw must not be tightened when not mounted or else pressure may deform the unit.

FEATURES: Fast and frequent mounting / dismantling with only one set screw. Redial screw positioning saves space along the shaft. Accurate positioning. No axial movement when mounted. Uniform surface pressure against shaft and hub prevents damage to surfaces and enables the use of small diameter hubs. Handles temperature range: -30°C to +82°C.

OPERATION: When the pressure screw is tightened to the recommended tightening torque, the double-walled sleeve expands uniformly against shaft and hub and creates a rigid joint. Dismantling is done by loosening the screw which returns the connector to its original dimensions. It can then easily be dismantled.

L = x 106

L = life expectancy expressed in number of revolutions

Ca = dynamic load rating (N), see specifications table

Fm = average axial load (N)

Example: For 10 mm pitch screw, Ca = 4200 N carrying an average axial load, Fm = 200 N (45 lbs.) the expected life is:

L = x 106 = 9.261 x 109 revolutions.

At an average of 1000 rpm this will result in:

x = 154,000 hours

of expected operational life. Note that the nature of the motion (jerky, smooth, etc.) will affect the life expectancy.
