ABSTRACT:
The friction surfaces (4) of two essentially annular friction elements (1) which, through relative motion, can be arranged to transmit torque, are each approximately formed like the surface of a spherical layer whose center (M) is situated on the axis (5) of the annular frictional elements (1) outside the bottom plane of the spherical layer. This is a simple way to ensure a whole-surface, interlocking contact and a good friction performance over a large number of cycles even during a minor tilt of the two cooperating friction surfaces (4).
