V-belt assembly for transmitting power

摘要

A V-belt assembly trained over U-belt wheels for transmitting power and which includes a flexible endless belt, a plurality of rigid suspension members secured fixedly to the endless belt perpendicularly to the longitudinal direction of the endless belt and rigid transmission pieces surrounding the respective suspension members in the section perpendicular to the longitudinal direction of the endless belt, supported pivotal projections projecting sideways from both sides of the suspension members and capable of engaging V-shaped grooves in the V-belt wheels. This rigid transmission piece is shaped in the generally rectangular form constituted from two generally U-shaped pieces. At least one of the pivotal projections of the suspension member and holes in the transmission piece located approximately in the center of a space between the top surface and the bottom surface of the transmission piece fitted on the pivotal projections of the suspension member is coated with an antifriction material layer. Two generally U-shaped pieces of the transmission piece are coupled with each other by a joint member in at least one of the top and bottom of these pieces.
