摘要： A bearing arrangement for a turbocharger, including a bearing housing-which extends in an axial direction, an anti-friction bearing, situated within the bearing housing, having an outer bearing ring and a number of rolling bodies and an axially extending shaft which is rotatably mounted within the bearing housing. It is provided that the shaft includes a rolling body raceway for guiding the rolling bodies. Moreover, the invention relates to a turbocharger having such a bearing arrangement. A bearing arrangement of this type allows the secure mounting of a shaft in a turbocharger with simple assembly and low costs.

摘要： The invention proposes a switchable cam follower (1) for a valve train of an internal combustion engine, said cam follower comprising two elements (2, 3) telescoped into each other and, axially displaceable relative to each other. A bore (4) comprising at least one piston (5) extends in the inner element (2). The piston (5) has, on a portion of its outer peripheral surface (7), a stepped entraining surface (8) that starts from the first front end (6) of the piston (5) facing the outer element (3). For achieving coupling, the piston (5) can be displaced with this entraining surface (8) onto a flat counter surface (10) of the other element (3). The entraining surface (8) of the piston (5) extends, starting from the first front end (6), toward a second front end (11) of the piston (5) while tapering into a conical shape generally in the direction toward a longitudinal axis of the piston (5). Besides this, an edge region (12) of the entraining surface (8) on the first front end (6) is additionally provided with a cylindrical, outwards arched (with reference to a starting point of the radius (R)) contour (13) that extends orthogonally to the longitudinal axis of the piston (5). In this way, during the coupled state of the piston (5) and its inevitable tilting, the edge abrasion feared in the prior art does not occur any longer. The manufacturing tolerances in the region of coupling can be coarsened, i.e. slackened.

摘要： A method of grinding control edges of a control bush of a rotary slide valve for hydraulic steering of motor vehicles, includes placement of the control bush in a support in form of slide shoes or a V block and additionally securing the control bush in the support by pressure rollers. A precise angular positioning of the control bush is effected by press-fitting a mandrel into the interior of the control bush. After grinding the control bush to a predetermined outside diameter, the reference points commensurate with the angular position of the individual control edges are determined by a measuring system. Based on the determined reference points, an optimum reference point for the angular position of all control edges is computed and utilized for adjusting the mandrel in form of a zero point shift for grinding the control edges.
