Shoe for guiding the running of a transmission chain

摘要

A shoe formed to relieve a sliding frictional resistance between a shoe for guiding the running of a transmission chain and the transmission chain, the cross-sectional shape of an incoming end and an outgoing end of a shoe (11) (11') for guiding a transmission chain is formed from a flat pressing-contact surface (12) for slidably guiding bottoms of all transmission chain plates. The flat surface extends longitudinally a short distance and transversely. The cross-sectional shape of an intermediate section between the incoming end and said outgoing end is formed with a convex pressing-contact surface (13A), (13B) for slidably guiding an bottom of less than all of the transmission chain plates, and has a transverse cross-section in which the pressing-contact surface or surfaces does not extend across the full width of the shoe to provide a recess for lubricant, and provide pressing-contact with less than all of the transmission chain plates.
