Detailed Description
The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.
The motor of the present invention is explained with reference to fig. 1, 2 and 3. The utility model discloses a motor includes motor housing 5, and housing 5 is at its inside vacuole formation, and stator module, rotor subassembly 4 etc. hold in this cavity. The housing may have various shapes such as a cylindrical shape, a prismatic shape, and the like. In the exemplary embodiment shown in fig. 1, the housing 5 has a cylindrical configuration. The housing 5 is open at both ends, closed at one end by the end cap 3 and at the other end by the flange portion 6.
The rotor assembly 4 comprises a rotor shaft, one end of which passes through the end cap 3 and is supported in the end cap 3, for example by means of a bearing 10, and the other end of which passes through the flange portion 6 and is supported in the flange portion 6, for example by means of a bearing 7. A connection to a reduction gear, which is shown in fig. 1 in the form of an output tooth 9, is provided on the rotor shaft. Preferably, a spacer 8 is also provided between the output dog 9 and the bearing 7.
In addition, a magnetic ring 1 is arranged outside the motor end cover 3. Preferably, a gasket 2 is further disposed between the magnetic ring 1 and the bearing 10.
As can be seen from fig. 3, as a possible embodiment, the motor end cover 3 and the flange 6 are both fixedly arranged on the motor housing 5. A hole is arranged at the opening edge close to the motor shell 5, and the hole forms a metal rib on the motor shell 5. Correspondingly, the corresponding strip-shaped grooves are respectively arranged on the motor end cover 3 and the flange part 6, and ribs on the motor shell 5 are riveted and pressed into the strip-shaped grooves during assembly, so that the motor end cover 3 and the flange part 6 are clamped and fixed at two ends of the motor shell 5.
Further, the magnetic rings 1 and the output teeth 9, which are respectively provided at both ends of the rotor shaft of the motor, may be firmly coupled to the rotor shaft by means of, for example, riveting or the like. In order to prevent the axial movement of the rotor shaft, on one hand, a boss is arranged on the axial end face of the motor end cover 3, and the end face of the boss is abutted with the end face of the magnetic ring 1, so that the axial movement of the rotor shaft in one direction is limited; on the other hand, a boss is also provided on an axial end face of the flange portion 6, and an end face of the boss abuts on an end face of the output dog 9 to restrict movement of the rotor shaft in the other axial direction. Therefore, the magnetic ring 1 and the output teeth 9 which are arranged at the same time can play a role of axially fixing the rotor shaft.
