Stationary pulley and shaft assembly for a continuously variable transmission

摘要

A pulley shaft (10) and stationary pulley (20) assembly for a belt drive mechanism of a continuously variable transmission includes an inner surface of the pulley having metal-cutting serrations (26), a blocking surface (30), and a surface (28) for engaging a pilot guide surface (16) formed on the shaft (10). The shaft (10), formed of softer material than the hardened pulley (20), includes a shoulder (12) adapted to have serrations (32) formed in it during the assembly process, a pilot guide surface (16), and a blocking surface (14) adapted to contact the blocking surface (30) of the pulley (20).
