A motor coupling with protection function

Abstract

A motor shaft coupling with a protective function, which relates to the technical field of electromechanical equipment, includes a housing, the inner side of the housing is provided with evenly distributed card slots, the middle part of the housing is sleeved with an output shaft, and the outer side of the output shaft is The swivel connection has evenly distributed stops. The motor coupling with protective function is used through the cooperation of the stopper and the clamping block. The stopper is clamped with the housing in the initial state. When the motor is stuck, the stopper will be squeezed and shrunk into the output shaft. And the piston rod 2 protrudes under the hydraulic principle of the hydraulic tank, and pushes the rotary block to rotate clockwise. The rotary block drives the block to move to the inner side of the output shaft through the limit groove, so that the block shrinks into the output shaft, so that the There is no clamping connection between the output shaft and the housing. At this time, the output shaft can rotate normally in the middle of the housing, and the pulley on the stopper can reduce the friction force, thereby achieving the function of protecting the motor and reducing the friction. The load of the motor prolongs the service life of the motor.

Description

technical field [0001] The invention relates to the technical field of electromechanical equipment, in particular to a motor shaft coupling with protection function. Background technique [0002] Electromechanical equipment refers to automation equipment such as machinery or tools. Most electromechanical equipment is automated through motors, such as transmission devices. The motor drives the conveyor belt through the coupling to achieve the effect of automatic transmission. [0003] Most of the current couplings for motors convert the rotation of the output shaft into the rotation of gears or rotating rods in all directions, and the transmission efficiency is high. However, most of the current couplings do not have protection devices. When the motor rotates to the maximum displacement, the motor Most of them cannot rotate due to the limitation of displacement, but the motor is still in working condition, which causes the temperature of the motor to rise and the load to mult...

[0003] Most of the current couplings for motors convert the rotation of the output shaft into the rotation of gears or rotating rods in all directions, and the transmission efficiency is high. However, most of the current couplings do not have protection devices. When the motor rotates to the maximum displacement, the motor Most of them will not be able to rotate due to the limitation of displacement, but the motor is still in working condition, which will cause the temperature of the motor to rise and the load to multiply, resulting in a greatly shortened service life of the motor and an increase in the maintenance cost of electromechanical equipment.
