摘要

The shaft (1) has base bodies (10) separately manufactured and axially engaged on the shaft through sliding, and cams (2-9) fixed on the base bodies. A fixation (11) is formed by using a ball bearing (17) and provided on the bodies. The ball bearing comprises an exterior ring (18) and interior ring (20), which is axially fixed and integrated in rotation on the bodies for fixing an antifriction bearing (19) on the bodies of the shaft. An independent claim is also included for a method for manufacturing a base body axially engaged on a shaft.
