Abstract
A motor/gear-train drive unit, and particularly a motor-vehicle power-window drive or the like, which can be manufactured and assembled at low cost, and which comprises a motor frame (1) enclosed in the circumferential direction and an adjacent gear case (2) at one of its axial ends and a closing bearing cap (3) at its other axial end, can be obtained by making the bearing cap (3) with a brush support plate (5) mounted therein and bonded therewith. Plug pins (41, 42) extend outwardly through the bearing cap (3). The preassembled subassembly that is axially displaceable, tightly sealed (seal ring [7]), relative to the motor frame (1) and can be secured in a given final operating position to the motor frame (1).
Claims16
A motor/gear-train drive unit, comprising:
- a motor frame having an inner surface;
- a commutator motor enclosed in said motor frame;
- a gear case disposed adjacent to said motor frame;
- and
- a preassembled subassembly including:
- a bearing cap;
- a brush support plate mounted in said bearing cap;
- and
- plug pins bonded to said brush support plate and extending outwardly, in a sealed manner, through said bearing cap;
- said subassembly having an outer surface which conforms to said inner surface of said motor frame so as to be continuously displaceable, by insertion, relative to said motor frame and able to be secured to the motor frame in a final operating position;
- and
- a peripheral seal ring tightly sealing said subassembly from said motor frame.
