Abstract
An improved mounting means for the rollers of a roller conveyor apparatus comprising a tubular bushing having a body portion which extends through the polygonal-shaped holes in the adjacent support structure into the polygonal-shaped shaft opening or bore of a bearing assembly sitted within the end of a roller and a tubular pin having a shaft portion extending through the bushing. The bushing has longitudinal slots running from the remote end along the body portion forming a plurality of resilient members and internal radially extending knobs on the resilient members. The circumference of the bushing is sufficiently large within the bearing shaft opening to prevent rotational motion of the contacting element in the bearing assembly. The pin has a complimentary groove circumferentially disposed about the shank portion near the remote end which causes the knobs and therefore resilient members to expand outwardly against the bearing assembly when the pin is fully inserted into the bushing. The expansion of the resilient members prevents retrograde motion of the bushing and pin and also creates an additional frictional constraint against rotation.
