Reed structure for preventing axial drifting of motor, motor and household appliance

Abstract

The invention belongs to the technical field of motor damping devices, and discloses a reed structure for preventing axial drifting of a motor, the motor and a household appliance. A ship-shaped spring piece is arranged on a primary gear or between the primary gear and a central gear. The ship-shaped spring piece installed on the primary gear is of a concave structure. The ship-shaped spring pieceinstalled between the primary gear and the central gear is of a protruding structure. The length of the ship-shaped spring piece of the concave structure is smaller than the diameter of the gear. Thelength of the spring piece is smaller than the diameter of the gear, and pressure is larger than a radial force. The spring piece structure is additionally arranged on the gear, so that axial force borne by the gear in the rotating process is reduced, and all the gears are prevented from colliding with a gear plate (or the surface cover).

Description

technical field [0001] The invention belongs to the technical field of shock absorbing devices for electric motors, and in particular relates to a reed structure for preventing axial movement of electric motors, electric motors and household appliances. Background technique [0002] At present, the commonly used existing technology in the industry is as follows: the permanent magnet synchronous motor has broad application prospects in the field of household appliances because of its advantages such as simple structure, high efficiency, and low production cost. Among them, the noise caused by the collision between the gear and the gear plate (or cover) due to the axial force is a kind of phenomenon, and the noise phenomenon is a quality problem that is extremely important in synchronous motors. [0003] In the prior art, the problem of the noise caused by the axial force of the permanent magnet synchronous motor is seldom solved. Although the shock-absorbing rubber is added i...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the problem of the noise caused by the axial force of the permanent magnet synchronous motor is seldom solved. Although the shock-absorbing rubber is added in the cavity of the working component to avoid the shaking of the shock-absorbing rubber, it cannot effectively solve the problem of gear hitting the gear. The noise problem induced by the plate (or face cover) cannot solve the problem of excessive axial force during the rotation of the gear
