[0033] Working principle: Before using this long-service-life motor bearing, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 -Figure 7 As shown in the figure, a lubrication assembly 2 is provided on one side of the front housing 1. When lubricating the bearing body 102, lubricating oil is added inside the housing 201, the end cover 202 is covered on the top of the housing 201, and the end cover 202 is tightened by the threaded connection between the fixing ring 204 and the annular groove 203. Then, rotating the screw rod 208 can push the piston 209 to move. The piston 209 can eject the lubricating oil inside the housing 201 out of the discharge pipe 205, so as to push the conical rubber block 215 to move. Furthermore, the sliding rod 211 can be driven by the fixing rod 212 to slide on the fixing block 210 and compress the telescopic spring 213, so that the discharge pipe 205 is no longer blocked, and the lubricating oil can enter the oil outlet pipe 207 through the sealing shell 206. The lubricating oil enters the inside of the bearing body 102 through the oil outlet pipe 207 and the lubricating hole on the bearing body 102, so that the bearing body 102 can be lubricated with lubricating oil. Furthermore, the bearing body 102 can be lubricated. The lubrication assembly 2 facilitates the addition of lubricating oil to the bearing body 102, facilitates the later maintenance of the bearing body 102, is convenient for the user to use, reduces the wear of the bearing body 102, and improves the service life of the bearing body 102;

[0034] A positioning assembly 3 is provided inside and outside the front housing 1. When installing the bearing body 102, the outer ring of the bearing body 102 can be positioned through the keyway and the flat key. The bearing body 102 is placed in the installation groove 101, so that the bearing body 102 can push the positioning block 304 to move. Furthermore, the movable rod 303 can be pushed to slide on the support block 302 and compress the return spring 305, so that one side of the bearing body 102 is attached to the support ring 103. Under the action of the return spring 305, the positioning block 304 is reset and attached to the other side of the bearing body 102, so that the bearing body 102 is positioned. Then, the knurled screw 314 can be tightened to prevent the positioning rod 312 from moving. Furthermore, the movable rod 303 can be prevented from moving, and the positioning block 304 can be prevented from accidentally moving to affect the reliability of the positioning of the bearing body 102. When disassembling the bearing body 102, loosen the knurled screw 314 and pull the L-shaped rod 308 on one side to move. After the L-shaped rod 308 on one side moves, the rotating part 310 can be pulled to rotate through the connecting rod 311 on one side. After the rotating part 310 rotates, the L-shaped rod 308 on the other side can be pushed to move, so that when the L-shaped rod 308 on one side is pulled to move, the two L-shaped rods 308 can move away from each other at the same time. Furthermore, the movable rod 303 can be driven to move through the mounting rod 306, so that the movable rod 303 drives the positioning block 304 to move, and the positioning block 304 retracts into the connecting groove 301, so that the bearing body 102 loses its limit, and then the bearing body 102 can be removed. The positioning assembly 3 facilitates the installation and disassembly of the bearing body 102, which not only facilitates the positioning and installation of the bearing body 102, but also facilitates the later replacement of the bearing body 102, improving the practicability.

[0035] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
