ABSTRACT:
An intermittent indexing apparatus has a simple structure of supporting portions for bearings without requiring complicated manufacturing processes. The intermittent indexing apparatus includes input shaft, an output shaft, and a housing. An indexing cam is provided on the input shaft and engages cam followers disposed on the peripheral surface of a turret fixed to the output shaft. Opposite ends of the input shaft and the output shaft are rotatably supported by respective first and second pairs of bearings in the housing. First and second openings are formed through opposite side walls of the housing. The second pair of bearings are enabled to slide in an axial direction of the output shaft for positioning. The first opening has a sufficient diameter for introducing therethrough the output shaft with the cam followers. Threaded holes having larger diameters than those of the openings are formed on the outer side portions of the openings so that retainers can be screwed thereinto from the outside of the housing.
