Drive transmission for roller conveyors.

摘要

A roller conveyor drive chain is equipped with drive transmission elements (30) for frictionally contacting the rollers (12) of the conveyor (10). Each element (30) is secured to a respective link of the chain (15) and extends at each end beyond this link to overlap the adjacent chain link. The parts of the elements (30) which project beyond their own chain link are an assymetrical wedge shape, having one side extending at an acute angle to the length of the chain (15) so that two adjacent elements (30) overlap one another laterally and have a line of separation which is acutely inclined across the chain (15) to reduce transmission noise as the elements (30) pass in contact with the rollers (12).
