Problems solved by technology

[0004] (1) When the motor needs to be repaired, the power may not be turned off in time during the disassembly of the moving motor, causing the motor to run during the moving process, resulting in secondary damage to the motor. Secondly, when the motor shaft rotates at high speed, the lubrication in the bearing sleeve The oil provides sufficient lubrication for the bearing sleeve at the current speed, which will intensify the wear in the bearing sleeve, and when the motor shaft is excessively fatigued or worn, the shaft cannot be replaced quickly;
[0005] (2) When the motor is running, the inside will heat up. If the motor cannot be cooled in a timely and effective manner, the motor may explode due to the high-temperature and high-pressure gas gradually generated inside, causing serious property losses.

Embodiment 1

[0027] see Figure 1-5, an explosion-proof motor for mining new energy vehicles, including a motor case 1, the bottom of the motor case 1 is connected with a base 4 through bolts, the right side of the motor case 1 is connected with a protective case 1 through bolts, and the bottom of the motor case 1 Stator windings 51 are installed on the inner wall, and the outer wall on the right side of the motor housing 1 is sleeved with a bearing sleeve 41 that penetrates and extends into the motor housing 1. The bearing sleeve 41 can avoid the friction between the motor shaft 26 and the motor housing 1. The bearing sleeve The inner ring of 41 is sleeved with the motor shaft 26, the left end of the motor shaft 26 is clamped with the rotor 15, and the right side of the stator winding 51 is fixedly connected with the zero line 25 that runs through and extends to the outside of the protective case 3, and the cooling pipe 2 communicates with the outside world. The temperature is exchanged t...

Embodiment 2

[0029] see Figure 1-5 , on the basis of Embodiment 1, the top of the motor shaft 26 is welded with a stopper 49, the bottom of the motor shaft 26 is connected with an L-shaped block 32 through bolts, and the outer ring of the motor shaft 26 is sleeved with a second pulley 31 and a pressing Disk 29, the second pulley 31 can be fixed on the motor shaft 26 through the L-shaped block 32 and the stopper 49. The inner ring of the second pulley 31 is provided with an L-shaped clamping hole, and the inner ring of the pressing disk is provided with a first Through holes, the left side of the pressure plate 29 is welded with the first spring 30 sleeved on the outer ring of the motor shaft 26, and the end of the first spring 30 away from the pressure plate 29 is welded with the second pulley 31, and the left side of the second pulley 31 The side is welded with a fixed block 33, the second pulley 31 drives the fixed block 33 to rotate, the top of the fixed block 33 is welded with a secon...

Embodiment 3

[0031] see Figure 1-5 , on the basis of the second embodiment, a cavity is opened inside the motor shaft 26, and there is hydraulic oil in the cavity. The inner ring of the through hole is sleeved with a pressure block 48, and the top and bottom of the motor shaft 26 are provided with a third through hole, the third through hole is sleeved with a limit post 28, and the hydraulic oil in the cavity and the limit block 27 and the limit block 27 are passed through the third through hole. The cooperation of the limit post 28 can realize the clamping and loosening of the motor shaft 26, which makes the motor shaft 26 easy to replace and prevents the motor shaft 26 from breaking due to excessive fatigue or wear and causing danger.

Abstract

The invention discloses a mining new energy automobile explosion-proof motor, relates to the technical field of new energy motors, and aims to solve the problems of motor explosion and the like caused by the fact that a motor in operation cannot be timely and effectively cooled. The explosion-proof motor comprises a motor shell, and the bottom of the motor shell is connected with a base through bolts; and the right side of the motor shell is connected with a protective shell through the bolt. When the motor is damaged and needs to be detached from an automobile for maintenance, the live wire can be automatically disconnected, safety accidents caused by mistaken touch of a switch of the motor by workers in the moving process of the motor are prevented, the motor rotating shaft of the motor can be quickly replaced, and the maintenance time is saved. When the motor operates normally, corresponding lubricating oil can be added into the bearing sleeve according to the current rotating speed of the motor, the lubricating effect of the bearing sleeve is improved, meanwhile, the interior of the motor which operates normally is cooled all the time, and short-circuit explosion of the motor caused by damage of electrical elements due to a too high temperature of the motor is prevented.

Description

technical field [0001] The invention relates to the field of storage battery technology, in particular to an explosion-proof motor for a mine-used new energy vehicle. Background technique [0002] Motor (English: Electric machinery, commonly known as "motor") refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor is represented by the letter M (the old standard uses D) in the circuit. Its main function is Generate driving torque, as the power source of electrical appliances or various machinery, the generator is represented by the letter G in the circuit, and its main function is to convert mechanical energy into electrical energy. [0003] When the motor is working, the motor shaft will rotate, and the inside of the motor will generate heat, but the existing motor: [0004] (1) When the motor needs to be repaired, the power may not be turned off in time during the disa...
