Abstract
A housing for a motor-transmission unit with at least two housing sections which have in each case at least one accommodation segment for receiving a motor and an internally-toothed, internal ring gear segment for receiving a gear of a planetary gear unit, wherein the housing sections can be or are connected with each other and wherein, in the assembled state, the accommodation segments of the housing sections together form at least one accommodation compartment for holding the motor, and the internal ring gear segments of the housing sections together form an internal ring gear for mating with a gear on the planetary gear unit.
Claims17
A housing for a motor-transmission unit having a motor and a planetary gear unit having gears, the housing comprising:
- first and second housing sections each having at least one accommodation segment for a motor and an internally-toothed, internal ring gear segment for a planetary gear unit,
- wherein the first and second housing sections are configured to be connected with each other,
- wherein, in an assembled state, the accommodation segments of the first and second housing sections together form at least one accommodation compartment for the motor, and the internal ring gear segments of the first and second housing sections together form an accommodation compartment for the planetary gear unit including an internal ring gear for meshing with gears of the planetary gear unit,
- wherein the accommodation compartment for the motor is continuous with the accommodation compartment for the planetary gear unit at all radial positions of the planetary gear unit, and
- wherein the accommodation compartment for the motor is entirely closed on a first axial end thereof and is at least partially open on a second axial end thereof.
A motor-transmission unit comprising:
- a motor having a rotor shaft;
- a planetary gear unit having a first end for receiving the rotor shaft and a second end terminating in an output shaft;
- first and second housing sections each having at least one accommodation segment for receiving the motor and an internally-toothed, internal ring gear segment for operatively connecting to the planetary gear unit,
- wherein the first and second housing sections are connected with each other,
- wherein, in an assembled state, the accommodation segments of the first and second housing sections together form at least one accommodation compartment for the motor, and the internal ring gear segments of the first and second housing sections together form an accommodation compartment for the planetary gear unit including an internal ring gear for the planetary gear unit, and
- wherein the accommodation compartment for the motor is continuous with the accommodation compartment for the planetary gear unit at all radial positions of the planetary gear unit, and
- wherein the accommodation compartment for the motor is entirely closed on a first axial end thereof and is at least partially open on a second axial end thereof.
