IPC: F16H55/36
Filed: 1993-04-28
Abstract: PURPOSE:To reduce the number of parts of a belt transmission device, and simplify manufacturing method of the installing member of a pulley. CONSTITUTION:A transmission device is provided in such constitution that a belt 45 is hooked around the pulley 44 and a driven member which are supported on the shaft 4 of a base 1 (a base seat 2). A shaft is inclined in direction which a belt is stretched and reverse direction. Force P applied on the pulley 44 is decomposited into force P1 for pushing down the pulley 44 on a base side and force P2 energizing in parallel direction on a pulley side. Even if force in upper direction is acted on the pulley 44, the force P1 for pushing down the pulley 44 on the base side is acted so as to prevent the pulley 44 from floating up. Since the noise prevention washer of the pulley 44 at the time of rotation is eliminated, it is thus possible to reduce the number of parts of the transmission device, and also reduce a cost. Since an inclining member 5 is formed on the base 1 and the base seat 2, and the base seat 2 is inclined by shrinkage at the time of forming thereof, it is possible to simplify manufacture of a metal mold shape and the base seat 2.
