INSTALLATION STRUCTURE OF POWER TRANSMIT FOR SUPER CHARGER

摘要

A power transmission installation structure for a super charger is provided to install the super charger easily at the side opposite from the power generating side of an engine by arranging a bracket and a driving pulley at one side of the engine. A power transmission installation structure for a super charger(70) includes a bracket(10), a driving pulley(20), and a power transmission unit(40). The bracket is tightened onto one side of an engine where a crank pulley(50) is positioned. The driving pulley is mounted on the bracket, and receives power from the crank pulley through a timing belt and rotates. The power transmission unit has one end connected to a center shaft of the driving pulley and the other end connected to a turbine shaft of the super charger through a belt. The bracket is equipped with an auxiliary pulley(30) connected to the crank pulley to ensure tensile force of the timing belt for rotating the driving pulley. The power transmission unit includes a cylindrical housing, and a shaft arranged in the housing to transmit power. The shaft has one end connected to the center shaft of the driving pulley and the other end equipped with a shaft pulley and connected to a fan shaft of the super charger through a belt. A flange(71) is arranged at one end of the housing and joined to one side of the super charger through a pin(72). The flange further includes a roller(73) for ensuring tension of the belt connected to the shaft pulley.
