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.
Claims5
A pulley for transmitting rotational motion between first and second rotating shafts with a belt on an automobile engine, the pulley comprising:
- a shaft mount with a central hole that is sized and configured to the first rotating shaft of the automobile engine, the shaft mount having a plurality of threaded holes;
- a body having a plurality of countersunk through holes sized and configured to be aligned to the plurality of threaded holes of the shaft mount, the countersunk through holes defining a first inner diameter and a second inner diameter, the first inner diameter being less than the second inner diameter;
- a plurality of bolts defining a neck and a head, the neck defining a first outer diameter, the head defining a second outer diameter;
- wherein a difference between the first inner diameter and the first outer diameter is less than a difference between the second inner diameter and the second outer diameter;
- wherein the body has an inner cavity sized and configured to receive the shaft mount.
