Abstract

The invention belongs to the technical field of motors, and particularly relates to an overload protection motor for load-carrying machinery, which comprises a driving motor, a fixed seat, a movable seat, a first connecting piece, a second connecting piece, a first convex block, a second convex block, an output shaft, a stop block, a first spring and a second spring. When the output shaft is locked, the driving motor drives the first connecting piece to rotate relative to the second connecting piece, so that teeth on the first connecting piece are meshed with the tooth surface, provided with the first convex block, of the second connecting piece, the first convex block is compressed into the pressure cavity, and the second convex block at the other end of the pressure cavity is extruded out; the stop block completely enters the sliding groove in the output shaft, then the output shaft and the second connecting piece are not restrained in the rotating direction, then the motor is separated from a force transmission path of the load end through a mechanical structure, overload protection of the motor is achieved, the structure is simpler, the number of needed parts is smaller, and cost is lower.

Description

technical field [0001] The invention belongs to the technical field of electric motors, in particular to an overload protection electric motor for heavy-duty machinery. Background technique [0002] Motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machines; it can be divided into DC according to the type of working power supply: Motor and AC motor; can be divided according to structure and working principle: can be divided into DC motor, asynchronous motor, synchronous motor; can be divided according to starting and running mode: capacitor starting type single-phase asynchronous motor, capacitor running single-phase asynchronous motor, capacitor Start-up and running single-phase asynchronous motors and split-phase single-phase asynchronous motors; can be divided by us...
