摘要： An automatic tensioner for applying a tension to a belt of an engine for a vehicle comprises a shaft fixedly mounted on a part of the vehicle. An arm has a proximal section which is supported by the shaft for angular movement thereabout, and a free end section of the arm is located on the side opposite to the proximal section. A pulley is supported by the free end section of the arm for angular movement thereabout and is in contact with the belt. A plate element is provided which is fixedly mounted on the shaft. A plurality of rolling elements are arranged between the proximal section of the arm and the plate element. The rolling element rolls between the proximal section of the arm and the plate element to support the proximal section for angular movement. The arm is moved angularly by a spring about the shaft to bias the pulley toward the belt.

摘要： A method for manufacturing a poly-V pulley includes a process for slitting and compressing the peripheral edge portion of an essentially flat blank for forming a widened and thickened flange wall. A series of relatively narrow, deep, V-shaped grooves are cold rolled. The poly-V pulley thus produced has the flange wall with poly-V grooves, from the intermediate portion of which a web extends radially inward. This structure provides good dynamic balance of rotation for the pulley and thus prolongs the life not only of the pulleys per se but also the belt to be put around the pulley. Further, the manufacturing method allows the manufacture of relatively small diameter poly-V pulleys.
