ABSTRACT:
An annular friction gear includes a driving shaft, a driving disc connected to the driving shaft, a driven shaft, a driven disc connected to the driven shaft, the shafts discs being coaxially mounted rotatably. An annular friction element, radially displaceable mechanically or hydraulically, between the discs rests in frictional contact at one contact point on the driving disc and at a diametrically opposite contact point on the driven disc. The friction element is in the form of a ball bearing disposed obliquely with respect to the shaft axis so that its outer race rests at one contact point on the driving disc and at the contact point on the driven disc. The displacement device engages on the inner race of the ball bearing.
