Kind Code:
A
Abstract:
PCT No. PCT/EP91/02272 Sec. 371 Date Dec. 7, 1992 Sec. 102(e) Date Dec. 7, 1992 PCT Filed Dec. 2, 1991 PCT Pub. No. WO92/14927 PCT Pub. Date Sep. 3, 1992.In order to connect a pump (1) with an electric motor (2) quickly and form-fittingly, a hollow, tappet-shaped stud (6) is formed onto the pot-shaped motor housing (7), specifically onto the bottom of the pot (10). The stud engages an insertion recess (5) of the pump. A driving eccentric (4) of the driven shaft (3) is connected with the pump during the assembly of the pump. If the inside of the tappet-shaped stud (6) is to receive the first motor bearing, a fit is needed at the inside as well as at the outside of the stud. If the motor housing (7) is made from deep drawn sheet metal, the double fit is only possible, if, when viewed in the circumferential direction, the cross section of the wall of the stud (6) is formed like a wave. This facilitates the use of a plastic cover (18) in connection with the sheet metal housing (7) and the avoidance of a carbon brush support plate. In connection with a further embodiment, the lack of a support plate facilitates an automatic assembly of the motor (2) as well as the combination with plug connections and electronic housings.
