Technical Field

[0002] The motor rotor is also a rotating part in the motor. The motor consists of two parts: the rotor and the stator. It is a device used to realize the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy. The motor rotor is divided into the motor rotor and the generator rotor, and the rotating support is the part where the rotor is installed.

The utility model sets the rotating shaft to both sides of the casing and the cover, so that the rotating shafts with shafts at both ends can carry loads. The outer rotor brushless motor adopts a double shaft, and the two supports can be directly fixed in the whole machine on the circumference of the seat body, reducing the need to add a mounting bracket to fix the motor.
[0004] With respect to the above-mentioned related technologies, the applicant believes that the current and above-mentioned mounting brackets are all installed on the outer surface of the rotor, and the bracket contains a bearing inside, which is sleeved on the outer surface of the rotor to reduce the friction of the rotor during rotation. The bearing is usually located inside the motor housing. The bearing needs to be lubricated after a certain period of use, usually once every two to three months to avoid severe wear of the bearing. The motor is usually disassembled and overhauled every six months to one year, so it is far from enough to just add lubricating oil during maintenance. Therefore, some of the time, the staff needs to disassemble the motor housing to lubricate the bearing, and the operation of disassembling the housing is relatively cumbersome. For this reason, we propose a motor with a motor rotor rotating bracket. Utility Model Content

[0034] The following is combined with Figure 1-6 This application is described in further detail.
[0035] See also Figure 1-6 A motor with a motor rotor rotating support includes a main body module 100 and two support modules 200. The main body module 100 includes a shell 110. A rotor 120 is arranged inside the shell 110. One end of the rotor 120 extends to the outside of the shell 110. The two support modules 200 are arranged between the outer surface of the rotor 120 and the inner wall of the shell 110. The outer surface of the rotor 120 is provided with a stator 130 located between the two support modules 200. The outer surface of the shell 110 is connected to two insertion tubes 140. The outer surfaces of the two insertion tubes 140 are both threadedly connected with a first sealing cover 150. The support module 200 includes a bearing 210 sleeved on the outer surface of the rotor 120. The outer surface of the bearing 210 is fixedly sleeved with a set block 2 20.

[0036] When it is necessary to add softening oil to the bearing 210, the staff opens the first sealing cover 150, and then inserts the screwdriver into the oil tank 240 through the insertion tube 140, and then repeatedly presses the injection assembly 260 with the screwdriver. When the injection assembly 260 is pressed down, the lubricating oil inside the oil tank 240 will be pressed into the inside of the diverter groove 250 through the penetration, and the lubricating oil inside the diverter groove 250 will pass through the two bearings 210. The subsequent injection assembly 260 is reset, and the injection assembly 260 is repeatedly pressed to make the lubricating oil repeatedly sprayed onto the bearing 210, and the bearing 210 is driven to rotate by the rotor 120, so that the balls inside the bearing 210 roll, and the lubricating oil flows evenly, thereby completing the oiling. After the oiling is completed, the screwdriver is pulled out and the first sealing cover 150 is re-covered, so that the staff can complete the lubrication of the bearing 210 without disassembling the outer shell 110. Each time the outer shell 110 is disassembled to repair the motor, the lubricating oil is added to the oil tank 240.

At the same time, the sealing annular block 265 is withdrawn from the annular groove. The lubricating oil inside the oil groove 240 will be pressed into the inside of the diverter groove 250 through the penetration. The lubricating oil inside the diverter groove 250 will be sprayed toward the bearing 210 through the two injection tubes 270. The subsequent reset spring 263 drives the piston plate 261 to reset. The two limit blocks 266 can limit the range of movement of the piston plate 261 each time, and control the amount of lubricating oil ejected. By repeatedly pressing the piston plate 261, the lubricating oil is repeatedly sprayed toward the bearing 210. By setting the end of the two injection tubes 270 away from the diverter groove 250 to be conical, the lubricating oil is pressurized, which facilitates the injection of the lubricating oil into the bearing 210.

[0040] The support module 200 can be installed by setting up multiple mounting bolts. Each time the housing 110 is disassembled to maintain and overhaul the motor, the second sealing cover 290 is opened and lubricating oil is added to the oil tank 240 through the oil filling pipe using a syringe, thereby avoiding the need for staff to frequently disassemble the housing 110 to lubricate the bearing 210.
[0041] The implementation principle of the embodiment of the present application is as follows: when it is necessary to add softened oil to the bearing 210, the staff opens the first sealing cover 150, then inserts a screwdriver into the oil groove 240 through the insertion tube 140, and then repeatedly presses the piston plate 261 with the screwdriver. When the piston plate 261 is pressed down, the sealing block 264 will be driven down through the pressure rod 262, and the sealing annular block 265 will be withdrawn from the annular groove. The lubricating oil inside the oil groove 240 will be pressed into the inside of the diverter groove 250 through the penetration, and the lubricating oil inside the diverter groove 250 will be sprayed toward the bearing 210 through the two injection tubes 270. The subsequent reset spring 263 drives the piston The plate 261 is reset, and the two limit blocks 266 can limit the range of movement of the piston plate 261 each time, and control the amount of lubricating oil injected. By repeatedly pressing the piston plate 261, the lubricating oil is repeatedly sprayed to the bearing 210, and the bearing 210 is driven to rotate by the rotor 120, so that the balls inside the bearing 210 roll, and the lubricating oil flows evenly, thereby completing the oiling. After the oiling is completed, the screwdriver is pulled out and the first sealing cover 150 is re-covered, so that the staff can complete the lubrication of the bearing 210 without disassembling the outer shell 110. Each time the outer shell 110 is disassembled to repair the motor, the lubricating oil can be added to the oil tank 240.
[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
