Abstract
In a drive belt system, an idler pulleyis formed by an auto belt alignment pulley. For example, a pulley bodyis rotatably carried on a hollow cylindrical shaft member, a support rodis inserted in the shaft member, and the pulley bodyand the shaft memberare connected to each other via a pin(pivot axis C) for angular movement about the pin. The pinis inclined orthogonally to the shaft memberand forward in the direction of rotation of the pulley bodywith respect to the direction of a radial shaft load L. With this configuration, when a flat beltdeviates to one side, the pulley bodyinclines to create a level difference in the direction of the radial shaft load L and angularly moves orthogonally to the flat belt, thereby correcting the deviation of the flat belt. To fulfill the auto belt alignment function, belt span lengths Si and So between the idler pulleyand both the adjacent pulleysandare each set larger than the width of the flat belt
