Abstract
A slip clutch of the friction type is described for interposition between a rotary shaft and a driven or driving element on the shaft, such as a gear, cam, pulley, crank or the like, the slip clutch including a split sleeve in engagement with the element or the shaft but retained against movement by a key carried in a keyway on the shaft or in the element, a split tolerance ring being interposed between the split retainer ring and the shaft or the element and retained against rotation with respect to each other and to the shaft or the element in the shaft by the key. The gear, cam, pulley and the like is retained against longitudinal movement along the shaft in any desired manner such as by a shoulder on the shaft and a split retainer ring in a groove on the shaft or by a pair of spaced retainer rings in grooves on the shaft.
