Conveyor noise isolation and wear prevention system
First Claim
1. A conveyor roller noise isolator system for mounting a conveyor roller to a conveyor system support frame, said noise isolator system comprising;
- a frame having an opening therein defined by a peripheral surface;
a conveyor roller axle;
a resilient unitary bushing insertable into the frame opening,said bushing having a body with an inside surface and an outside surface separated by a wall,said outside surface having a non-circular cross-section that is shaped and sized to be received by the opening in the frame,said inside surface defining an axle opening having a non-circular cross-section that is shaped and sized to receive the axle, andat least one of the axle opening and the outside surface cross sections of the bushing being shaped and sized for an interference fit between the bushing and the frame or between the bushing and the axle for deforming the wall to securely engage the bushing to the frame and to the axle when the bushing is inserted into the frame and the axle is inserted into the bushing.

Abstract
The invention is embodied in a conveyor roller noise-isolator and wear-prevention system for mounting a conveyor roller to a conveyor system support frame. An apparatus is provided in which a conveyor roller axle is mounted to a conveyor side frame by a resilient bushing which serves to isolate the noise generated at the roller, prevent the noise generated at the interface between the axle and the frame, and prevent wear on the axle and the frame. The bushing achieves these goals by eliminating metal-to-metal contact at the mount interface and by having interference fits with the axle and with the frame to prevent relative motion.
