Tightening roller for traction mechanism drive, e.g. belt drive of internal combustion engine, comprises traction mechanism connecting driveshaft and connective, where tightening roller has radial outer running disk

摘要

The tightening roller (1) comprises a traction mechanism connecting a driveshaft and a connective, where the tightening roller has a radial outer running disk (3). A knurling (20,21) is formed axially and radially outside a lateral surface (14) of an outer bearing ring (5) in a spherical bevel (18,19). The bevel forms a transition from the radial outer lateral surface to the front side (16,17) of an outer bearing ring.
