ABSTRACT:
A stepping gear includes an output member attached to a wheel which is provided with a number of rollers on both faces thereof. In driving contact with these rollers is a pair of cam members having contours which allow for driving in the forward direction as well as a standstill or dwell phase. In addition, reverse movement of the wheel is made possible by providing an undercut in one of the cams coupled with a superelevation on the other of the two cams. Form locking engagement between the cams and the rollers is maintained during the forward driving phase, and the standstill and return phases as well.
