ABSTRACT:
An adjustable pulley of the split-sheave type is formed of stamped sheet metal and is retained assembled by a Belleville spring engaging deformations on one sheave part and a tang struck from the other sheave part. One sheave part has a plurality of cam seats facing a mating portion on the other sheave part, the latter having a plurality of cam surfaces of varying heights thereon. The cam surfaces are deformed areas projecting a predetermined distance toward the cam seats. Rotation of one sheave part to position particular cam surfaces upon the cam seats places the sheaves a predetermined axial distance apart establishing a predetermined effective belt groove width permitting use of various belts.
