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.
Claims24
A pulley for transmitting rotational motion between first and second rotating shafts of a continuously variable transmission with a belt, the pulley being fixed to the first rotating shaft, the pulley comprising:
- first and second parts being traversable closer to or further away from each other,
- each of the first and second parts mounted onto the first rotating shaft of the continuously variable transmission,
- each of the first and second parts having a skewed surface which interfaces with the belt and collectively forms a groove,
- a laser induced friction surface applied to a portion of the skewed surfaces of the first and second parts which engage the belt during operation of the continuously variable transmission,
- the first and second parts fabricated from a metallic material, and
- the laser induced friction surface comprising patterned kerfs applied to the skewed surfaces of the first and second parts,
- wherein each of the patterned kerfs comprise recast material deposited about the kerf to increase a coefficient of friction of the skewed surfaces compared to skewed surfaces without the laser induced friction surfaces,
- wherein the recast material comprises a plurality of peaks and valleys, and
- wherein the recast material deposited about each kerf is generated by a roughing laser beam vaporizing a portion of an outer surface of the skewed surface.
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 kerfs formed in a first outer surface of the first rotating shaft, and
- wherein each of the kerfs comprise recast material that extends outward above the first outer surface by a plurality of distances.
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 groove formed circumferentially about the central axis for receiving the belt, the at least one groove defining a valley and a peak,
- the body fabricated from a metallic material, the at least one groove defining a belt engaging surface between a peak and a valley of the at least one groove;
- and
- a plurality of kerfs 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 kerfs extends outward above an outer surface of the belt by a plurality of distances.
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 groove formed circumferentially about the central axis for receiving the belt,
- wherein the cylindrical central hole defines a central axis about which the body rotates,
- wherein the body comprises a metallic material,
- wherein the at least one groove defines a belt-engaging surface between a peak and a valley of the at least one groove,
- wherein a plurality of kerfs form a pattern across a peak and a valley of the at least one groove to define a laser induced friction surface for increasing a coefficient of friction between a surface of the body and a surface of the belt, and
- wherein recast material comprising the metallic material is disposed around the kerf and extends above the belt engaging surface by a plurality of distances.
