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.
Claims18
A pulley for transmitting rotational motion between first and second rotating shafts with a belt, the pulley being fixed to the first rotating shaft, the pulley comprising:
- a pulley body defining a belt engaging surface mountable onto the first rotating shaft;
- and a laser induced friction surface formed on the belt engaging surface,
- wherein the laser induced friction surface comprises patterned vaporized grooves formed in the belt engaging surface, and
- wherein recast material having a plurality of peaks and valleys is deposited in each of the patterned vaporized grooves.
A pulley for transmitting rotational motion between first and second rotating shafts with a belt on an 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 engine,
- the cylindrical central hole defining a central axis about which the body rotates, the body having at least one belt groove formed circumferentially about the central axis for receiving the belt,
- the body fabricated from a metallic material, the at least one belt groove defining a belt engaging surface;
- and
- a plurality of vaporized grooves forming a pattern in the belt engaging surface defining a laser induced friction surface for increasing a coefficient of friction of the belt engaging surface wherein each of the plurality of vaporized grooves has recast material having a plurality of peaks and valleys deposited in each of the plurality of vaporized grooves.
A pulley for transmitting rotational motion between first and second rotating shafts with a belt, the pulley being fixed to the first rotating shaft, the pulley comprising:
- a body having a cylindrical central hole that receives the first rotating shaft and the body has at least one belt groove formed circumferentially about a the central axis for receiving the belt,
- wherein the cylindrical central hole defines the central axis about which the body rotates,
- wherein the body comprises a metallic material,
- wherein the at least one belt groove defines a belt-engaging surface,
- wherein a plurality of laser vaporized grooves form a pattern across the at least one belt groove to define a laser induced friction surface for increasing a coefficient of friction between the belt-engaging surface of the body and a surface of the belt, and
- wherein recast material having a plurality of peaks and valleys comprising the metallic material is disposed in the plurality of laser vaporized grooves.
