Attachment by clamp assy

Principle

By tightening the screws, the user deforms a conical ring, and causes a strong force between the shaft and bore. The liasion obtained is complete and rigid (i.e. recoil-free) , and easily removed.

Advantages

By avoiding the manufacturing accidents which can be caused whilst cutting keyways etc… This system actually increases the sectional strength of the shaft and decreases both the concentration of stress points and the phenomenon of metal fatigue cracking.

For equal diameters, the transmissible torque with this method is much higher. Work to be done on the shaft and bore is limited to insuring an H8/h8 tolerance and a surface finish of at least Ra=1,6mm for self-centering assemblies (RT25 and RTL450).

A guide should be envisaged for the other assemblies. These locking assemblies are recommended for all types of toothed wheels, and especially for pulleys, sprockets and gears with large pitches or important modules.
