Abstract

The invention is applicable to the field of motors, and discloses a rotor assembly and an oil bearing motor, wherein the rotor assembly includes a rotating shaft, a rotor installed on the rotating shaft, a first oil bearing installed on the rotating shaft and located on one side of the rotor, and a first oil bearing installed on the rotating shaft On the second oil bearing on the other side of the rotor, where the first and second clamps are installed on the rotating shaft, the first clamp is located between the first oil bearing and the rotor, and the second clamp is located between the first oil bearing and the rotor. 2 Between the oil bearing and the rotor. In the present invention, the positioning structure of the shaft sleeve is replaced by a double circlip positioning structure, and the setting of parts such as rubber gaskets, nylon gaskets and steel balls in the rear end cover is cancelled, thus effectively simplifying the structure, processing procedures and The assembly process; and completely eliminate the impact of steel balls, greatly reducing the vibration noise of the oil-impregnated bearing motor; at the same time, it also greatly reduces the axial movement defect rate of the oil-impregnated bearing motor.

Description

technical field

[0001] The invention belongs to the field of motors, in particular to a rotor assembly and an oil bearing motor with the rotor assembly. Background technique

[0002] Such as Figure 4 As shown, in an existing oil-impregnated bearing motor of a pulsator washing machine, a shaft sleeve 6' positioning structure is arranged between the front oil-impregnated bearing 200' and the rotor core 5', and a positioning structure is provided between the rear end surface of the rotating shaft 1' and the rear surface of the rotating shaft 1'. A steel ball 7', a nylon washer 8' and a rubber washer 9' are arranged between the end caps 300'. The oil-bearing motor has the following disadvantages in specific applications: 1) its structure is complex, the parts and shaft 1' have many processing steps, and the assembly process is complicated; 3) By the stretching depth of the end cover, the thickness of the rubber gasket 9', the thickness of the nylon gasket 8', the steel ball so...
