Abstract

A shaft stop bushing (1) is proposed which is retained in a given position on a shaft (6) by means of a radially resilient stop ring (12). The stop bushing (1) has a longitudinal bore (4) with two circular grooves (7 and 11) of different diameters, between which a funnel-shaped section (10) is formed. The stop ring (12) is inserted in the larger groove (11) so that stops bushing (1) and stop ring (12) form a pre-assembled subassembly (1, 12). The preassembled subassembly (1, 12) can be slid onto the shaft (6) by a simple automatized process without the stop ring (12) touching the shaft (6). The stop ring (12) is retained in its axial position relative to an annular groove (16) of the shaft (6) and is pressed into the annular groove (16) by the stop bushing (1) upon further axial movement of the stop bushing. The entry funnel-shaped section (10) presses the stop ring (12) until, in the assembled state, the smaller-diameter circular groove (7) engages over the stop ring (12).
