Abstract: The stepping gear mechanism is provided in particular for motion control of a machine tool turret and comprises two cam plates adapted to be driven in rotation in the same sense about an axis of rotation each and arranged in such manner with respect to a roller supporting member that circular stop zones of both cam plates each engage a roller at the same time and in mutually counteracting fashion, whereby the roller supporting member is prevented from rotating. Subsequently, a projection of a cam plate engages one roller, while another roller dips into an indentation of the other cam plate so that the roller supporting member will be rotated. The cam plates are disposed adjacent each other and their projections are movable past each other in overlapping relationship such that, alternating with these conditions of engagement, the stop zones of both cam plates engage one and the same roller simultaneously and opposingly, whereby the roller supporting member once again is prevented from rotating.
