POWER TRANSMISSION MECHANISM WITH COGGED V-BELT

摘要

A power transmission mechanism (10) having a V-belt (11) provided with transverse reinforcing elements (22). The V-belt, in the illustrated embodiment, defines a cog belt wherein the reinforcing elements are disposed within the cogs (15) thereof to have opposite end surfaces (23) exposed at the side edge surfaces (21) of the belt. A thin film of lubricating fluid (27) is provided on the exposed end surfaces of the reinforcing elements for improved long troublefree operation of the mechanism. Different structures for providing the thin film of lubricating fluid are disclosed. In the illustrated embodiments, the thin film extends along the entire side edge surfaces of the V-belt.
