DETAILED DESCRIPTION

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figures 1-4 As shown, this utility model provides a wear-resistant bearing, including a central shaft 1, and an external wear-resistant auxiliary device 2 is provided on the outer wall of the central shaft 1; the external wear-resistant auxiliary device 2 includes: an oiling lubrication component 22 and a heat dissipation wear-resistant protection component 21, the heat dissipation wear-resistant protection component 21 being provided on the outer wall of the central shaft 1.

[0021] The heat dissipation and wear-resistant protection assembly 21 includes: a heat dissipation pipe 211, a heat dissipation aluminum plate assembly 212, a wear-resistant reinforced shaft 213, a first rotating groove 214, a second rotating groove 217, a rotating ball assembly 215, and an outer shaft 216. The second rotating groove 217 is formed inside the outer shaft 216, the first rotating groove 214 is formed on the upper outer wall of the wear-resistant reinforced shaft 213, the inner wall of the wear-resistant reinforced shaft 213 is installed on the outer wall of the heat dissipation aluminum plate assembly 212, and the inner wall of the heat dissipation aluminum plate assembly 212 is installed on the outer wall of the central shaft 1. Two sets of heat pipes 211 are provided, and the two sets of heat exhaust pipes 211 are respectively installed at the front and rear ends of the central shaft 1. The rotating ball assembly 215 is rotatably installed inside the first rotating groove 214 and the second rotating groove 217. The inner and outer walls of the outer shaft body 216 are the same size and model. The outer wall of the wear-resistant and reinforced shaft body 213 is rotatably set inside the outer shaft body 216. The inner size and model of the outer shaft body 216 are compatible with the outer wall size and model of the wear-resistant and reinforced shaft body 213.

[0022] The lubrication assembly 22 includes: a lubricating oil storage chamber 221, an oil dispensing valve port 222, and an oil inlet groove 223. Two sets of oil inlet grooves 223 are provided, and the two sets of oil inlet grooves 223 are respectively provided. Two sets of oil dispensing valve ports 222 are provided, and the two sets are respectively installed inside the lower end of the two sets of lubricating oil storage chambers 221. The inner side of the lubricating oil storage chambers 221 is respectively installed on the outer wall of the two sets of oil inlet grooves 223. The lubricating oil storage chamber 221 is annular, and the size of the lubricating oil storage chamber 221 is compatible with the size of the two sets of oil inlet grooves 223.

[0023] The specific implementation method is as follows: When using this utility model, lubricating oil needs to be added into the lubricating oil storage tank 221 through the oil inlet valve 222. After the oil is added, the lubricating oil can be automatically dispensed in a metered manner through the lubricating oil storage tank 221. When the device is in use, a lot of heat will be generated inside. If the heat cannot be dissipated in time, it will accelerate the loss of lubricating oil poured into the first rotating groove 214 and the second rotating groove 217, reduce the lubricating performance of the lubricating oil, and cause wear and tear on the rotating ball assembly 215, resulting in a rapid reduction in the service life of the rotating ball assembly 215. This device can conduct the heat generated inside the first rotating groove 214 and the second rotating groove 217 through the heat dissipation aluminum plate assembly 212. After the heat inside the first rotating groove 214 and the second rotating groove 217 is dissipated, the heat is then dissipated through the air circulation at both ends. This device achieves rotational heat dissipation through simple heat conduction, which greatly improves the service life of the entire device.

[0024] The working principle of this utility model is as follows: When using this utility model, lubricating oil needs to be added into the lubricating oil storage tank 221 through the oil inlet valve 222. After the oil is added, the lubricating oil can be automatically dispensed in a metered manner through the lubricating oil storage tank 221. When the device is in use, a lot of heat will be generated inside. If the heat cannot be dissipated in time, it will accelerate the loss of lubricating oil poured into the first rotating groove 214 and the second rotating groove 217, reduce the lubricating performance of the lubricating oil, and cause wear and tear on the rotating ball assembly 215, resulting in a premature reduction in the service life of the rotating ball assembly 215. This device can dissipate the heat generated inside the first rotating groove 214 and the second rotating groove 217 through the heat dissipation aluminum plate assembly 212.
