ABSTRACT:
The invention relates to a transmission for driving a movable element, particularly a component in a machine tool, at high speed or creep speed, in the form of a divided drive having one branch for the transmission of high speed and one branch for the transmission of creep speed and at least one member in one of the two branches being locked when creep speed is selected. The invention provides that for high speed and creep speed a pulse motor is provided and that for compensating the error in the actual position of the movable element from its required position an adjusting clutch is provided.
