FIELD: machine building.SUBSTANCE: proposed device comprises tubular case, preferably, rack case (1) of rack body (10) and at least one retention and/or thrust ring (2, 2') arranged at least partially inside case (1). Said retention and/or thrust ring (2, 2') is press-fitted by its expansion into case (1). It differs from know designs in that outer circular surface of said retention and/or thrust ring (2, 2') has toothed section (4, 4') abutting on case (1). Invention covers also the appropriate assembly process for fitting at least one retention and/or thrust ring (2, 2') inside case (1).EFFECT: higher hardness and quality, lower costs.14 cl, 2 dwg |
