  • Drive device for several units of a machine
    Patent number: 6386057
    Abstract: The inventive drive device for several units of a machine has an inertia drive with an inertia drive spindle (1) driven by a motor, and several inertia drive nuts (2), the nuts being fitted on the inertia drive spindle (1) and being allocated to the units. The inertia drive nuts (2) are each arranged in the housings of the units in such a way that they can turn but cannot be displaced axially. During the rest phase of a particular unit, the inertia drive nut (2) is solidly connected to the inertia drive spindle (1) with a first positive and/or nonpositive fit. For the movement phase of the aggregate, the nut (2) is disconnected from the spindle (1) and is solidly connected to the housing with a second positive and/or nonpositive fit.
