Belt drive mechanism and its manufacturing method

摘要

The mechanism has a mount (10) defining a geometric reference plane (34) and provided with a strut (16) making projection perpendicular to the reference geometric plane. A shaft (30) traverses the strut and the geometric reference plane. A pulley drum is provided with a tread to cooperate with a driving belt and a face (66) axially supporting against a sub-assembly. A fixation stud (68) fixes the drum to the sub-assembly, and is arranged parallel to a geometric rotation axis (26), and a rotating unit e.g. blade wheel (36), is integrated to a shaft and located in a side of the reference plane. An independent claim is also included for a method for assembling of a driving mechanism.
