Abstract
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.
Claims1
A pulley for transmitting rotational motion between first and second rotating shafts with a belt on an automobile engine, the pulley being fixed to the first rotating shaft, the pulley comprising:
- a body having a cylindrical central hole for receiving the first rotating shaft and mounting the body onto the first rotating shaft on the automobile engine, the cylindrical central hole defining a central axis about which the body rotates, the body having at least one groove formed circumferentially about the central axis for receiving the belt;
- and
- a laser infused friction material bonded to an outer surface of the at least one groove.
Dependencies are inferred from the claim text.
