Abstract: A right angle indexer includes an internal torque limiter. The indexer includes an input shaft with a cam, and an output shaft. The cam on the input shaft rotates a hub on the output shaft. The hub is rotatable relative to the output shaft. The output shaft has a driven surface, and the hub has a drive surface. The drive surface includes a plurality of detents which are irregularly spaced about the drive surface. A plurality of rollers are spaced irregularly about the driven surface. The driven plate is biased into contact with the drive plate, and the rollers are received in the drive plate detents. As long as the rollers are engaged in the drive plate detents, rotation of the hub by the cam will cause the driven plate, and hence the output shaft, to rotate. However, if a predetermined torque load is exceeded, the driven plate will become disengaged from the drive plate, and continued rotation of the hub will not cause rotation of the driven plate or the output shaft.
