摘要

A pulley assembly having a body, a shaft mount and a plurality of bolts is disclosed. The body is aligned to the shaft mount by providing a tight tolerance between a shoulder portion of the bolt and a neck portion of a counter sunk hole formed in the body. Additionally, an outer surface of the body may have a pattern of friction lines or patches formed by fusing particulate matter to the outer surface with heat generated by a laser beam.

主权项

1. A method for increasing a coefficient of friction of surface of a pulley, the method comprising the steps of:
disposing a laser machine adjacent to the pulley so that a laser beam of the laser machine is applied to an area of the surface of the pulley; adjusting the laser machine to a roughing setting to emit a laser beam that vaporizes the surface of the area to increase a roughness of the pulley surface; applying the laser beam of the laser machine onto the pulley surface with the laser machine set to the roughing setting; adjusting the laser machine to a smoothing setting to emit the laser beam to reduce sharps peaks on the pulley surface caused by the applying the laser beam of the laser machine set to the roughing setting; applying the laser beam of the laser machine onto the pulley surface with the laser machine set to the smoothing setting.
