Description

[0002] When bearing is running at high speed, a large amount of heat will be generated, so that the temperature of the bearing rises too high, and a reasonable lubrication mode and device can effectively take away the heat generated by the bearing to reduce the temperature rise of the bearing. When the bearing is running at high speed, due to the action of centrifugal force, the lubricating oil injected into the bearing will be thrown to the outer ring raceway of the bearing under the action of centrifugal force, so that the amount of lubricating oil in the inner ring of the bearing is reduced or even insufficient, and the inner ring of the bearing is rotating at high speed, which makes the temperature of the inner ring of the bearing much higher than that of the outer ring, and the temperature of the inner ring of the bearing rises too high, which is easy to cause the inner ring to wear and scorch, thereby damaging the service performance of the bearing, and further affecting the working performance of the entire transmission system. Therefore, it is necessary to start from the lubricating device of the bearing to improve the lubrication state of the bearing, reduce the temperature rise of the bearing, and improve the reliability and durability of the bearing and the entire system.

The bearing lubricating device is provided with a special lubricating oil channel on one side of the bearing, so that the lubricating oil entering the lubricating system can not only realize oil injection lubrication, but also can keep a certain amount of lubricating oil in the bearing inner ring to avoid the lubricating oil in the bearing inner ring being too little and the temperature of the bearing inner ring rising too high under the action of high-speed centrifugal force. The oil storage cavity on one side of the bearing inner ring can also cool the bearing.

A pneumatic push rod 2202 is fixedly installed at the bottom of the push rod 224. A fixed column 2203 is fixedly connected to the output end of the pneumatic push rod 2202. A mounting groove 226 is opened at the bottom of the fixed column 2203. Rollers 227 are rotatably connected to the front and rear sides of the inner wall of the mounting groove 226. A cam 228 is movably connected to the outer wall of the roller 227. A turntable 229 is fixedly connected to both the front and rear ends of the cam 228. The outer wall of the rear turntable 229 is rotatably connected to the inner wall of mounting groove 216. A fixed sleeve 3 220 is movably connected to the outer wall of the front turntable 229. Fixed sleeve 3 220 and fixed sleeve 220 are movably connected to the inner wall of mounting groove 216. 25. The outer wall of the fixing sleeve 223 is fixedly connected to the inner wall of the mounting groove 216. A gear 2201 is fixedly connected to the front end of the turntable 229. The outer wall of the gear 2201 meshes with the outer wall of the gear ring 17. The sealing and draining assembly 23 includes a connecting plate 231. A sealing plate 232 is fixedly connected to the bottom of the connecting plate 231. An oil outlet hole 236 extending from the front to the rear of the sealing plate 232 is provided. The outer walls of the connecting plate 231 and the sealing plate 232 are movably connected to the inner wall of the mounting groove 217. A connecting plate 233 is fixedly connected to the upper right side of the connecting plate 231. The outer wall of the connecting plate 233 is movably connected to the inner wall of the mounting groove 215. The bottom of the connecting plate 233 is fixedly connected to the top of the limiting post 221.A trapezoidal plate 234 is fixedly connected to the right side of the connecting plate 231 and the sealing plate 232. The outer wall of the trapezoidal plate 234 is movably connected to the inner wall of the dovetail groove 219. A trapezoidal plate 235 is fixedly connected to the left side of the connecting plate 231 and the sealing plate 232. The outer wall of the trapezoidal plate 235 is movably connected to the inner wall of the dovetail groove 210. By activating the pneumatic push rod 2202, the fixed column 2203 pushes the roller 227 to contact the outer wall of the cam 228. As a result, when the inner ring 15 of the bearing rotates, it will drive the gear ring 17 to rotate synchronously. The rotation of the gear ring 17 is transmitted through gears. 2201 transmits the signal to the turntable 229, causing the cam 228 to rotate. The rotation of the cam 228 applies pressure to the roller 227, causing the push rod 224 and the limit post 221 to reciprocate up and down under the guidance of the second fixed sleeve 225 and the first fixed sleeve 223. The movement of the push rod 224 further drives the second connecting plate 233 to move synchronously, thereby realizing the up and down movement of the sealing plate 232. When the sealing plate 232 moves upward, the oil outlet hole 236 aligns with the oil outlet hole 218 of the mounting groove 217, and the lubricating oil in the oil storage cavity 212 will flow through the oil outlet hole 218. The lubricant flows into the oil outlet hole 236 and eventually into the oil inlet groove 14 of the high-speed bearing 1, providing lubrication for the rolling elements 13 and the rolling groove 12. When the protrusion of the cam 228 slides past the outer wall of the roller 227, the elastic force of the spring 222 will reset the limit post 221, thereby driving the sealing plate 232 to move downward and re-seal the oil outlet hole 218, realizing intermittent supply of lubricating oil and effectively avoiding excessive consumption of lubricating oil. When the trapezoidal pneumatic push rod 2202 reverses and causes the roller 227 to disengage from the outer wall of the cam 228, the sealing plate 232 will remain in the downward position, and the oil outlet hole 23... The misalignment of the 6th sealing plate with the oil outlet 218 stops the supply of lubricating oil. This not only allows for flexible control of the lubricating oil flow according to actual needs but also effectively prevents leakage and waste of lubricating oil during equipment shutdown or low-speed operation. Furthermore, dovetail grooves 219 and 210 ensure the stability of trapezoidal plates 234 and 235 during movement, preventing the sealing plate 232 from shifting. Simultaneously, the symmetrical distribution of the two sealing and draining components 23 ensures that the lubricating oil is evenly distributed to both sides of the high-speed bearing 1, thereby effectively improving lubrication and extending the bearing's service life.

[0023] like Figures 8-10As shown, the collecting structure 3 includes an oil storage assembly 31. A limit assembly 32 is provided on the front side of the oil storage assembly 31. The oil storage assembly 31 includes an arc-shaped plate 311. An inclined oil inlet plate 312 is fixedly connected to the rear side of the inner wall of the arc-shaped plate 311. A protective plate 313 is fixedly connected to the front side of the inner wall of the arc-shaped plate 311. The outer walls of the arc-shaped plate 311, the inclined oil inlet plate 312, and the protective plate 313 are movably connected to the inner wall of the semi-annular through hole 2101. An inserter is fixedly connected to the front side of the protective plate 313. Frame 314, limiting assembly 32 includes a double-hole plate 321, the rear side of the double-hole plate 321 is fixedly connected to the rear end of the mounting ring 211, the inner wall of the double-hole plate 321 is movably connected to a limiting rod 322, the lower side of the outer wall of the limiting rod 322 is fitted with a spring 323, the bottom of the two limiting rods 322 is fixedly connected to a fixing plate 324, the bottom of the fixing plate 324 is fixedly connected to an insert plate 325, the outer wall of the insert plate 325 is movably connected to the inner wall of the frame 314, the fixing plate 324... A lifting block 326 is fixedly connected to the front side. By moving the lifting block 326 upward, the fixed plate 324 drives the insert plate 325 to move upward. At this time, the spring 323 is compressed, and the insert plate 325 gradually disengages from the interior of the insert frame 314, thereby releasing the limiting effect on the oil storage component 31. Then, the arc-shaped plate 311, together with the inclined oil inlet plate 312 and the protective plate 313, can be removed from the semi-annular through hole 2101 to facilitate the cleaning or recovery of the collected lubricating oil. 312 can effectively guide the lubricating oil into the interior of the arc-shaped plate 311, and can recycle and reuse the lubricating oil, reducing resource waste. When the oil storage component 31 needs to be reinstalled, the arc-shaped plate 311, the inclined oil inlet plate 312, and the protective plate 313 are inserted into the interior of the semi-annular through hole 2101, the insert frame 314 is aligned with the insert plate 325, the lifting block 326 is released, and under the elastic force of the second spring 323, the insert plate 325 will automatically insert into the insert frame 314 to achieve quick fixation.

[0024] Working principle of this invention: By activating the pneumatic push rod 2202, the fixed column 2203 pushes the roller 227 to contact the outer wall of the cam 228. When the inner ring 15 of the bearing rotates, it drives the gear ring 17 to rotate synchronously. The rotation of the gear ring 17 is transmitted to the turntable 229 through the gear 2201, causing the cam 228 to rotate. The rotational motion of the cam 228 applies pressure to the roller 227, causing the push rod 224 and the limiting column 221 to move under the guidance of the second fixed sleeve 225 and the first fixed sleeve 223. The reciprocating motion of the push rod 224 further drives the connecting plate 233 to move synchronously, thereby realizing the up-and-down movement of the sealing plate 232. When the sealing plate 232 moves upward, the oil outlet hole 236 aligns with the oil outlet hole 218 of the mounting groove 217. The lubricating oil in the oil storage cavity 212 will flow into the oil outlet hole 236 through the oil outlet hole 218, and finally enter the oil inlet groove 14 of the high-speed bearing 1, providing lubrication for the rolling elements 13 and the rolling groove 12. When the protrusion of the cam 228... When the roller 227 slides over the outer wall of the roller 227, the elastic force of the spring 222 will reset the limit pin 221, thereby driving the sealing plate 232 to move downward and re-seal the oil outlet 218, realizing the intermittent supply of lubricating oil and effectively avoiding excessive consumption of lubricating oil. When the trapezoidal pneumatic push rod 2202 is activated in the reverse direction, the sealing plate 232 will remain in the downward state when the roller 227 disengages from the outer wall of the cam 228, and the oil outlet through hole 236 will be misaligned with the oil outlet 218, thereby stopping the supply of lubricating oil. This not only allows for the intermittent supply of lubricating oil according to the oil outlet hole 236 but also ensures the intermittent supply of lubricating oil according to the oil outlet hole 218. The lubricating oil flow can be flexibly controlled according to actual needs, and the lubricating oil leakage and waste can be effectively prevented when the equipment is stopped or running at low speed. In addition, dovetail groove 1 219 and dovetail groove 210 ensure the stability of trapezoidal plate 1 234 and trapezoidal plate 235 during movement, and prevent the sealing plate 232 from shifting. At the same time, the symmetrical distribution of the two sealing and draining components 23 ensures that the lubricating oil can be evenly distributed to both sides of the high-speed bearing 1, thereby effectively improving the lubrication effect and extending the service life of the bearing. By moving the lifting block 326 upward, the fixing plate 324 causes the insert plate 325 to move upward. At this time, the second spring 323 is compressed, and the insert plate 325 gradually separates from the interior of the insert frame 314, thereby releasing the limiting effect on the oil storage component 31. Then, the arc plate 311, together with the inclined oil inlet plate 312 and the protective plate 313, can be taken out from the semi-annular through hole 2101, which facilitates the cleaning or recycling of the collected lubricating oil. The inclined oil inlet plate 312 can effectively guide the lubricating oil into the interior of the arc plate 311, enabling the recycling and reuse of the lubricating oil and reducing resource waste. When it is necessary to reinstall the oil storage component 31, the arc plate 311, the inclined oil inlet plate 312, and the protective plate 313 are inserted into the interior of the semi-annular through hole 2101, the insert frame 314 is aligned with the insert plate 325, the lifting block 326 is released, and under the elastic force of the second spring 323, the insert plate 325 will automatically insert into the insert frame 314, achieving quick fixation.
