Definitions
- the invention relates to an electric motor in a closed design according to the preamble of claim 1; such an electric motor is known from EP-Bl 0 221 304.
- a brush bridge with a one-piece molded plug housing radially projecting beyond the opening of the motor housing, is inserted in a snug fit into an open-end axial longitudinal slot of the motor housing and can be fixed in its operating end position by the opposite end shield. Openings are provided in the part of the connector housing which extends through the motor housing and through which electrical connecting lines extend from the outside to the brush arrangement arranged inside the motor housing.
- a squeezable seal is interposed as an individual part.
- a further simplification of assembly by reducing the number of components to be assembled individually and thus reducing the number of assembly steps is possible according to one embodiment of the invention in that the insulating material bushing is held on the brush plate and the sealing ring outside of the insulating material bushing starts tangential course is held prepositionable on the brush plate by means of support webs, the insulating material bushing and the sealing ring with its support webs being expediently molded directly onto the brush plate.
- the brush plate thus serves as a load-bearing component both for the insulating material feedthrough with the connecting lines injected therein and for the entire sealing ring, which is already held in such a position that it is mounted on the motor housing and end shield reaches its sealing operating end position without additional handling measures.
- annular groove extending over the circumference and adapted to the profile of the sealing ring is provided for inserting the sealing ring, which is designed such that, on the one hand, the sealing ring in the bearing plate before it contacts the motor housing well held and, on the other hand, after the mounting of the bearing plate on the motor housing is pressed tightly against the motor housing;
- a bead elevation running around the foot of the annular groove can advantageously be used to prevent the Press the shield against the motor housing into the bottom part of the sealing ring that lies against the groove base and additionally squeeze it in the sense of a tight system.
- the brush plate with the insulating material feedthrough and the sealing ring on the end shield, in particular in the sense of a preassembled component unit; in this case, the insulating material feedthrough engages in a force-fitting manner in an insertion opening that is open at the end on an axially projecting contact edge of the bearing plate.
- FIG. 1 shows an axial longitudinal sectional view of a commutator motor with a brush plate with sealing ring and insulating material bushing fixed to the right end shield
- FIG. 2 shows a frontal top view of the brush plate with a pre-mounted sealing ring and pre-assembled insulating material bushing according to FIG. 1
- FIG. 3 shows a radial longitudinal section the brush plate according to FIG 2 in section III-III.
- FIG. 1 shows a permanently magnetically excited small DC motor with a cup-shaped motor housing 1 and partial shell magnets 9 held on its inner circumference and a rotor arranged on a rotor shaft 11 with a commutator 12.
- the right open end of the motor housing 1 is closed by a bearing plate 5 protrudes from the rotor shaft 1 with an eccentric drive shaft end 13, which is used, for example, to drive a tappet of a hydraulic pump flanged to the right axial end of the commutator motor.
- the motor housing 1 has at its right end a radially outwardly bent contact edge 14, which is used for the axial and radial fixing of the bearing plate 5 to the motor housing 1 and at the same time as a contact edge for a sealing ring 3 for moisture-tight closure between the motor housing 1 on the one hand and the end shield 5 on the other hand serves.
- Electrical connection lines 6, 7, which lead from the outside into the interior of the motor housing, and in particular serve for connection to electrical connection points on a brush plate 4 or a rotation detection 8 arranged between the tangential gaps of the partial shell magnets 9, are cast into an insulating bushing 2, which engages in an axially end-side insertion opening of an abutting edge 52 of the end shield 5 projecting axially against the motor housing.
- the insulating material bushing 2 with the injected electrical connecting lines 6, 7 is sprayed directly onto the brush plate 4.
- the circumferential sealing ring 3 is simultaneously cast in one piece, which is held in the tangential areas outside the insulating bushing 2 by means of support webs 31, 34 at a distance from the base plate of the brush plate 4 in such a way that the sealing ring 3 when the brush plate is installed - te 4 in the bearing plate 5 comes into contact with its final sealing position without major straightening work.
- a circumferential annular groove 52 is provided in the end shield 5 as a fixing aid for the sealing ring 3.
- Receptacles 42, 43 for hook-on brush holders and a receptacle for a plug connection of the rotation detector 8 are molded or cast onto the brush plate 4.
- the brush plate 4 expediently consist of a polyamide and the insulating material feedthrough 2 and the sealing ring 3 with its retaining webs 31-34 consist of an elastomer.
- the brush plate 4 with the parts of the insulating bushing 2 injection molded thereon with the injected connecting line 6, 7 and the sealing ring 3 molded over the support webs 31-34 can be fixed in the end shield 5 in the sense of a preassembled component unit, the insulating bushing 2 supports this fixation by its force-fitting insertion into the axial insertion opening of the contact edge 52 of the end shield 5.
- the insulating material bushing inserted into the insertion opening of the end shield 5 rests on the outside of the motor housing 1 with a sealing edge 21.
