Abstract (en)

[origin: EP0962656A2] The pump or motor (10) has elements for bearing of the toothed gears (32,34) and for torque transmission. The elements are bearing studs (36,38) integral with one of the gears and on either side of it, forming hollow bodies with a hub (40) for positive connection. The hollow bodies are manufactured in a sinter process. Both studs have identical axial dimensions. The hub has an internal toothed profile meshing with a counter profile on a shaft (26) to form and axially moveable non-turnable connection. Each bearing stud is guided in a bearing body of plastic, esp. of injection molded carbon phenolic resin.
