Shaftlock Cone Clamping Elements

Cone clamping elements are a purely friction method of clamping components to a shaft. The internal components within a cone clamp operate on a taper, so as the cone clamp is tightened the internal diameter decreases while the outside diameter increases. This change in diameters creates the clamping force.

There are two main advantages of cone clamps. The first is that for machining your component (i.e. a sprocket), the bore needs to be plain rather than being keyed or tapped and tapered. The second advantage is that the cone clamp acts as an overload protector, with excessive loading causing the clamp to spin on the shaft.

RCK11 Suitable for assemblies where special, even heavy-duty conditions are required, achieving maximum friction clamping results. It incorporates the best features of all the models which have been presented. It operates with very high torque values.

To Install
1 Ensure the hub and shaft surfaces are clean and degreased.
2 Apply a thin coating of light machine oil to screw threads and conical surfaces (do not use any molybdenum disulphide based or E.P. oils.
3 Align all of the component slots and loosely assemble the clamping element into the required position.
4 Tighten the clamping screws in diagonal sequence to the requisite torque, Ts.
5 If the application is subject to corrosive environmental conditions, apply grease to protect screw heads etc.

To Remove
1 Loosen all of the clamping screws in the same diagonal sequence as assembly.
2 Remove some bolts and insert them into the threaded hole that passes through the front clamping element cone and the centre section plate to reach the surface of the rear cone.
3 Tighten the screws sequentially to release the rear cone.
4 Remove some bolts and insert them into the threaded hole in the front cone so that they reach the centre section plate.
5 Tighten the screws sequentially to release the front cone.
6 Lubricate all screws with a light machine oil for the future use of the Challenge Cone Clamping Element.
