The invention describes a device () for calibrating a sintered molded part () with an angular toothing () by means of a calibrating tool (), comprising a lower punch () for mounting the sintered molded part () with a lower punch external toothing (), a vertically movable and axially rotatably mounted upper punch () with an upper punch external toothing (), as well as an axially rotatably mounted die () with a die internal toothing (). The lower punch () is mounted to be moveable only in vertical direction.

Device and method for calibrating a sintered molded part

The invention describes a method of machining a toothing () on an outer circumference () or an inner circumference of a work piece () made of pressed and sintered powder metal, by means of a rolling process carried out on the toothing () with two rotating section rolling wheels () which section toothing () engaging in the toothing of work piece (). The two section rolling wheels () are rotatably arranged in a common support frame () with an at least approximately constant distance between their section rolling wheel axles ().

Method and device for machining a toothing on a sintered part

The invention relates to a vane pump (), in particular a regulatable oil pump for a lubricating system, with a pump housing () with at least one housing tank () and with a vane rotor () disposed in the housing tank () mounted so that it can be rotated by means of a drive shaft () in the pump housing () constituting an axis of rotation () which provides a mount for vanes () in approximately radially extending fitting slots (). An adjusting ring () is provided enclosing the vane rotor () and circumferentially bounding pump cells () which, by means of a cylindrical internal wall surface (), can be displaced between a concentric position with respect to the vane rotor () and an eccentric position relative thereto, to which pressured is applied by positioning torques caused by the medium pressure and a positioning mechanism () in order to regulate a pressure level.
