ABSTRACT:
A hermetically sealed drive unit is provided in which a rotationally fixed face gear (27) is mounted within a spherical bore (29) on a bellows (47) so as to cause teeth (31) on the fixed face gear to (27) successfully engage teeth (24) on a rotatable face gear (23). The face gears (23, 27) have different numbers of teeth (24, 31) and therefore must rotate with respect to one another when the teeth (24, 31) engage each other successfully. The rotatable face gear (23) is mounted on one shaft (17), and another shaft (21) is provided with a cam (39). The shaft (21) with the cam rotates in order to cause the rotationally fixed face gear (27) to wobble within the spherical bore (29), causing the teeth (31) on the rotationally fixed face gear to engage the teeth (24) on the rotatable gear (23) in succession.
