Abstract
An auxiliary drive mechanism for use in association with a hydraulically actuated clutch has a gear wheel attached to the driven or output stage of the clutch, and a drive motor driving a pinion meshing with an intermediate gear. The intermediate gear protrudes into the casing which houses the clutch and can selectively engage the gear wheel. The auxiliary drive mechanism finds application where it is at times necessary to provide a drive at a speed lower than normal operating speed, for example to tension the chain of a scraper chain conveyor.
