Abstract
This drive device (1) comprises: a motor (2) including a cylindrical stator (23), a cylindrical rotor (24) facing the stator (23) in the radial direction, and a stator housing (25) in which the stator (23) and the rotor (24) are housed; a bevel gear (4) that is arranged on the axis of rotation of the motor (2) and to which the driving force of the motor (2) is transmitted; and a distribution mechanism (6) that transmits the driving force of the motor (2) via the bevel gear (4). At least part of the distribution mechanism (6) is arranged at a position overlapping with the outer circumferential lower surface of the stator housing (25).
Claims7
A drive device comprising:
- a motor including:
- a stator having a cylindrical shape;
- a rotor having a cylindrical shape, the rotor being radially opposed to the stator;
- and
- a stator housing that houses the stator and the rotor;
- a bevel gear that is disposed on a rotation axis of the motor and that a driving force of the motor is transmitted to;
- and
- a distribution mechanism that transmits the driving force of the motor via the bevel gear,
- wherein at least a part of the distribution mechanism is disposed at a position overlapping an outer peripheral lower surface of the stator housing.
A drive device comprising:
- a motor including:
- a stator having a cylindrical shape;
- a rotor having a cylindrical shape, the rotor being radially opposed to the stator;
- a stator housing that houses the stator and the rotor;
- and
- a rotor shaft having a cylindrical shape, the rotor shaft supporting the rotor and being rotatably supported by the stator housing via a bearing;
- a bevel gear that is disposed on a rotation axis of the motor and that a driving force of the motor is transmitted to, via a connection portion connected to the rotor shaft;
- and
- a distribution mechanism that transmits the driving force of the motor via the bevel gear,
- wherein an inner diameter of the rotor shaft is larger than an outer diameter of the bevel gear, and
- at least parts of the rotor shaft and the bevel gear are disposed at such positions that the at least parts of the rotor shaft and the bevel gear radially overlap each other.
