A reed structure for preventing axial movement of motors, motors, and household appliances

Abstract

The invention belongs to the technical field of shock absorbing devices for motors, and discloses a reed structure for preventing axial movement of motors, electric motors, and household appliances, which are provided with boat-shaped springs; the boat-shaped springs are installed on primary gears or installed on primary gears between the sun gear. The boat-shaped spring piece installed on the primary gear is a concave structure; the boat-shaped spring piece installed between the primary gear and the sun gear is a convex structure. The length of the boat-shaped spring piece of the concave structure is smaller than the diameter of the gear. The length of the spring leaf is smaller than the diameter of the gear, and the pressure is greater than the radial force. By adding a spring sheet structure to the gears, the axial force on the gears during rotation is reduced, and the collision between each gear and the gear plate (or face cover) is avoided.

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
