Explosion-proof and dust-proof stepping motor

Abstract

The invention discloses an explosion-proof and dust-proof stepping motor, and relates to the technical field of stepping motors, the explosion-proof and dust-proof stepping motor comprises a central shaft, the middle of the outer wall of the central shaft is fixedly sleeved with a stepping motor main body assembly, and a front end assembly is arranged on the outer wall of the central shaft and located on the left side of the stepping motor main body assembly; a rear end assembly is arranged on the right side of the outer wall of the center shaft and located on the right side of the stepping motor body assembly. Under the action of the front end explosion-proof cover and the fixed end cover, the front end of the stepping motor is protected, the explosion-proof performance of the front end of the stepping motor is improved, the problem of explosion of the front end of the stepping motor is prevented, under the action of the first explosion-proof rear end cover, the explosion-proof lengthened shell and the second explosion-proof rear end cover, the rear end piece of the stepping motor is protected, and the safety of the stepping motor is improved. The explosion-proof performance of the rear end of the stepping motor is improved, and the problem of explosion of the rear end of the stepping motor is prevented, so that the overall explosion-proof performance of the stepping motor is improved, the problem of explosion of the stepping motor during working is prevented, and the service life of the stepping motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of stepping motors, in particular to an explosion-proof and dust-proof stepping motor. Background technique [0002] Stepper motor is an open-loop control motor that converts electrical pulse signals into angular displacement or linear displacement. It is the main executive element in modern digital program control systems. The dust-proof tail of the stepper motor is an important factor affecting the service life of the stepper motor. , A good dust-proof structure can isolate the dust in the outside air and ensure that there is no impurities on the grating encoder inside the stepping motor, thereby protecting the normal operation of the stepping motor. [0003] The following problems exist for the prior art: [0004] 1. The explosion-proof performance of the existing explosion-proof and dust-proof stepping motor is poor, and the problem of damage to the stepping motor often occurs, thereby reducing the serv...

AI Technical Summary

Problems solved by technology

[0004] 1. The explosion-proof performance of the existing explosion-proof and dust-proof stepping motor is poor, and the problem of stepping motor damage often occurs, thereby reducing the service life of the stepping motor, which is not conducive to the long-term work of the stepping motor;

[0005] 2. The dust-proof effect of the existing explosion-proof and dust-proof stepper motors is poor, and it is not convenient to disassemble the dust-proof structure inside the stepper motor. Long-term use will cause the problem of blockage of the dust-proof structure, so that the guide post will not step. The air in the motor cannot flow normally, causing damage to the stepper motor;

[0006] 3. For the existing explosion-proof and dust-proof stepping motor, long-term work will cause the internal temperature of the stepping motor to rise, and the temperature inside the stepping motor will be too high to cause damage to the stepping motor
