Problems solved by technology
Among them, the cooling bushing is a plastic part. Although the cost of the cooling bushing made of plastic is relatively low, the cooling bushing has the following problems: 1. When the matching size of the plastic cooling bushing and the rotor shaft is too loose, the plastic cooling bushing Relative movement with the rotor shaft produces noise; 2. When the matching size of the plastic heat dissipation sleeve and the rotor shaft is too tight, the plastic heat dissipation sleeve will be pressed down with greater pressure, resulting in lower production efficiency of the motor and increased Labor cost

The invention discloses a rotor assembly and a motor comprising the same, the rotor assembly comprises: a rotor shaft, a rotor which is arranged on the rotor shaft and can rotate with the rotor shaft synchronously, a radiating shaft sleeve which is sleeved the rotor shaft and is arranged on at least one side of the rotor, wherein a first limiting member is arranged on the radiating shaft sleeve, a second limiting member is arranged on the rotor or the rotor shaft, and the first limiting member is cooperated with the second limiting member to prevent the rotation of the radiating shaft sleeve relative to the rotor. Therefore, the radiating shaft sleeve can rotate with the rotor shaft synchronously, so that the motor noise can be reduced, and the production efficiency of the motor can be improved.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a rotor assembly and a motor with the rotor assembly. Background technique [0002] In the related art, in order to dissipate heat for the rotor, the rotor shaft of the motor is provided with a heat dissipation sleeve, and the heat dissipation sleeve is arranged on one or both sides of the motor, and the heat dissipation sleeve can rotate with the rotor shaft. Among them, the cooling bushing is a plastic part. Although the cost of the cooling bushing made of plastic is relatively low, the cooling bushing has the following problems: 1. When the matching size of the plastic cooling bushing and the rotor shaft is too loose, the plastic cooling bushing Relative movement with the rotor shaft produces noise; 2. When the matching size of the plastic heat dissipation sleeve and the rotor shaft is too tight, the plastic heat dissipation sleeve will be pressed down with greater pressure, re...
