Variable-speed motor with damping structure and convenient for automatic torque adjustment

Abstract

The invention discloses a variable speed motor with a damping structure and convenient for automatic torque adjustment, and relates to the technical field of variable speed motors. The variable speedmotor in particular comprises a base and an initial rotating shaft assembly, a damping rubber pad is arranged at one side of the surface of the base, fixing bolts penetrate through the periphery of the bottom of a motor body, and the initial rotating shaft assembly is connected to one end of the motor body. A connecting rotating shaft penetrates through one side of the inner wall of a torque adjusting box, and a first torque gear is fixed to the outer wall of the connecting rotating shaft. According to the variable speed motor with the damping structure and convenient for automatic torque adjustment, by controlling a miniature electric telescopic rod to stretch out and draw back, a first gear and a first torque gear are meshed with each other or a second gear and a second torque gear are meshed with each other, so that the torque adjusting effect is achieved; moreover, only the miniature electric telescopic rod needs to be controlled to stretch out and draw back, operation is convenient for people, and parts do not need to be miniaturized and refined in the mode; the production and processing difficulty is reduced, and manufacturer production is facilitated.

Description

technical field [0001] The invention relates to the technical field of variable-speed motors, in particular to a variable-speed motor with a shock-absorbing structure that can facilitate automatic torque adjustment. Background technique [0002] Variable speed motor, also known as speed regulating motor or double speed motor, is a motor that can adjust its own speed to make the motor achieve higher performance. Due to its excellent performance, speed regulating motor has been widely used in steel, Power station, cable, chemical industry, petroleum, cement, textile, printing and dyeing, papermaking, machinery and other industrial sectors are used for constant torque or decreasing torque load mechanical stepless speed regulation, especially suitable for pumps and fans with large flow changes It is used for supporting the load and can obtain a good energy-saving effect. [0003] In the existing variable speed motor, the torque adjustment mechanism and the motor are co-located ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a variable speed motor with a shock absorbing structure that can facilitate automatic torque adjustment, which solves the problem that the torque adjustment mechanism and the motor of the variable speed motor proposed in the background technology are co-located inside a casing. As a result, the volume of the parts is miniaturized, which increases the difficulty of processing, requires high precision, and the casing is not easy to disassemble, which is not convenient for later maintenance and repair.
