ABSTRACT:
An adjustable, precision overload clutch device is disclosed as comprising a rotating driving member drivingly coupled by spring-urged detent plunger members to a driven member, in which bearings are provided for journalably mounting the head of each plunger member to the driving member, and spring adjusting members which permit pre-loading by the spring of each detent plunger and associated bearings. This combination allows the overload clutch to achieve a high locational accuracy upon each resetting after clearance of an obstruction. Elastomeric springs are preferably used for the detent plunger springs, so that by use of the adjusting member, the overload torque range for the precision overload clutch can be substantially adjusted (within limits) as desired for a given application. The clutch also includes structure to make it moisture resistant, including when coupled to an intermittent drive unit, such as a motor-driven indexer, for example.
