Abstract
A motor includes a motor housing, a rotating shaft assembly including a rotating shaft, a rotor, and a bearing in which the rotor and the bearing are mounted to the rotating shaft. The motor further includes a stator installed in the motor housing, the stator surrounding the rotor, a bracket mounted to the motor housing, and an elastic mesh that defines a plurality of pores, that is disposed between the bracket and the bearing, and that contacts at least one of the bracket or the bearing.
Claims19
A motor comprising:
- a motor housing;
- a rotating shaft assembly including a rotating shaft, a rotor, and a bearing, wherein the rotor and the bearing are mounted to the rotating shaft;
- a stator installed in the motor housing, the stator surrounding the rotor;
- a bracket mounted to the motor housing;
- and
- an elastic mesh that defines a plurality of pores, that is disposed between the bracket and the bearing, and that contacts the bracket and the bearing,
- wherein the elastic mesh has a hollow cylindrical shape and comprises a metal wire mesh comprising at least one metal wire,
- wherein the at least one metal wire has one or more curved portions, is irregularly tangled, and contacts both the bracket and the bearing,
- wherein the bearing comprises:
- an inner rim fixed to the rotating shaft,
- an outer rim spaced apart from the inner rim, and
- a rolling member disposed between the inner rim and the outer rim,
- wherein an internal diameter of the elastic mesh is less than or equal to an external diameter of the outer rim of the bearing, and
- wherein an inner circumference of the elastic mesh is in contact with an outer circumference of the outer rim of the bearing.
