A motor housing with good protective performance

Abstract

The invention discloses a motor housing with good protective performance. The structure comprises a housing, a heat dissipation fin, junction box, circulating cooling pipes and support legs are mounted on the housing, the heat sink is fixedly connected with the outer surface of the housing, the junction box is fixedly connected with the upper part of the housing, The circulating cooling pipe is fixedly connected with the outer surface of the housing, the support leg is movably connected with the lower surface of the housing, and the support leg is provided with a fixing hole, a built-in groove, a vibration damping spring and a limiting plate, the fixing hole is located at the middle of the support leg, and the built-in groove is located at the inner surface of the support leg. The invention can effectively reduce the transmission effect of the vibration amplitude in the working process of the motor through the increase of the vibration damping spring and the position limiting plate, enhance the protection function of the motor housing to the internal parts thereof, reduce the probability of friction between the rotating shaft and the motor housing due to the excessive vibration amplitude, and prolong the service life of the motor.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor casing with good protection performance. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. It is represented by the letter M in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. The generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy. At present, the most commonly used is to use heat energy, water energy, etc. to drive the rotor of the generator to generate electricity. [0003] At present, there are still some deficiencies in the existing motor casings. For example, the existing motor casings are generally directly fixed on the base by bolts, which cannot reduce the transmission effect of the vibration amp...

AI Technical Summary

Problems solved by technology

[0003] At present, there are still some deficiencies in the existing motor casings. For example, the existing motor casings are generally directly fixed on the base by bolts, which cannot reduce the transmission effect of the vibration amplitude during the working process of the motor, and weaken the impact of the motor casing on the motor. The protective function of its internal parts increases the chance of friction between the rotating shaft and the motor casing due to excessive vibration amplitude, shortening the service life of the motor, and the existing motor casings generally have cooling fans to dissipate heat from the motor. The method is relatively slow, and it is easy to burn the rotor wire group due to excessive heat accumulation inside the motor, which reduces the stability of the internal parts of the motor shell
