Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, specifically to a sliding bearing oil supply mechanism for an integrated structure of bearing housing and base plate. Background Technology

[0002] Currently, traditional bearing housings and base plates are mostly designed as separate units. During installation and use, not only are cumbersome positioning and fixing steps required, which consumes a lot of manpower and time, but the separate structure is also prone to relative displacement between the two due to long-term vibration or installation errors, affecting the stability and operational accuracy of the overall structure.

[0003] For example, patent number CN219911531U discloses a self-lubricating bearing housing, including a bearing housing body with an installation groove in which the bearing body is installed and confined; a lubrication assembly including an oil guide hole on the bearing body, an oil guide pipe connected to the upper end of the oil guide hole, and an oil reservoir connected to the other end of the oil guide pipe, the oil reservoir having an oil filling port; and a sealing assembly including a sealing plug disposed inside the oil reservoir. This utility model, through its lubrication assembly, allows for lubrication of the bearing body without disassembling the movable seat. Furthermore, the threaded rod allows for easy adjustment of the oil reservoir's open and closed state, enabling the sealing plug to be opened and closed as needed, preventing excessive lubrication or oil leakage during bearing body disassembly that would be difficult to clean.

[0004] For example, patent number CN 222963195 U discloses a bearing housing lubrication device, including a bearing housing mechanism and a lubrication filling mechanism. The lubrication filling mechanism is fixedly connected to the top of the bearing housing mechanism. The bearing housing mechanism includes a bearing housing body, and a bearing top cover is provided on the top of the bearing housing body. A filling port is provided on the top of the bearing top cover. The lubrication filling mechanism includes a lubrication box, which is fixedly connected to the top of the bearing top cover. A lubrication base is fixedly connected to the bottom of the inner wall of the lubrication box. A folding oil storage tank is connected to the top of the lubrication base, and a filling pipe is connected to the left side of the folding oil storage tank. This utility model adds the functionality of setting up a lubrication device for quick and convenient lubrication, enabling it to quickly add lubricating oil to the bearing housing and preventing the need to fill the bearing housing by aligning a lubricating oil bottle with the filling port.

[0005] While both patents include lubrication mechanisms, there is room for improvement in terms of automation and efficiency. Neither patent can automatically adjust the lubricant supply based on the spindle speed or operating status; they typically require manual periodic checks and addition of lubricant. This not only increases maintenance costs but also makes precise control of the lubricant supply difficult. When the spindle is running at high speed, insufficient or untimely lubrication can easily lead to overheating and accelerated wear of the sliding bearings, affecting the equipment's lifespan and operational safety. Conversely, if lubrication continues to be supplied when the spindle is running at low speed or stopped, it will waste lubricant, and excessive lubricant may overflow from the bearing housing, contaminating the equipment and the working environment.

[0016] Please see Figure 1-6This utility model provides a technical solution: a sliding bearing oil supply mechanism for an integrated bearing housing and base plate structure, including a bearing housing 1, an oil supply mechanism 2 connected to the upper end of the bearing housing 1, a bearing base 11 provided on the bearing housing 1, a bearing cover plate 12 connected to the upper end of the bearing base 11, a positioning pin 13 connected between the bearing cover plate 12 and the two sides of the bearing base 11, a bearing bottom shell 14 provided between the bearing base 11 and the main shaft 16, and a bearing cover shell 15 provided between the bearing cover plate 12 and the main shaft 16. An oil guide groove 151 is provided below the bearing 15. A driven shaft bracket 211 is connected to the upper end of the bearing cover plate 12. A driven shaft 215 is connected to the driven shaft bracket 211. A driven pulley 210 is connected to the rear end of the driven shaft 215. A second transmission belt 209 is connected between the driven pulley 210 and the driving pulley 208. A main shaft 16 is provided between the bearing base 11 and the bearing cover plate 12. A connecting plate 201 is connected to the front end of the bearing cover plate 12 and the bearing base 11. Two power wheels 202 are connected to the front end of the connecting plate 201. A rubber wheel 203 is connected to the front half of the drive wheel 202. The rubber wheel 203 is in close contact with the main shaft 16. A shaft bracket 206 is connected to the upper end of the connecting plate 201. Drive shafts 207 are connected to the left and right sides of the shaft bracket 206. A drive pulley 205 is connected to the front end of the drive shaft 207. A first drive belt 204 is connected to the drive pulley 205. The other end of the first drive belt 204 is connected to the rear half of the drive wheel 202. A drive pulley 208 is connected to the rear end of the drive shaft 207. A power supply pulley 208 is connected to the upper end of the bearing cover plate 12. The fuel tank 213 has a cam 212 inside, and an opening and closing frame 214 is provided on the upper side of the cam 212. An oil storage tank 216 is provided at the upper end of the fuel tank 213. The oil outlet at the bottom of the oil storage tank 216 is normally closed by the opening and closing frame 214. A guide frame 217 is provided at the bottom inside the oil storage tank 216. The guide frame 217 is connected to the upper end of the opening and closing frame 214. A compression spring 218 is connected between the guide frame 217 and the opening and closing frame 214. An oil tank cover 219 is provided at the upper end of the oil storage tank 216.

[0017] During operation, the main shaft 16 begins to rotate. Because the rubber wheel 203 is in close contact with the main shaft 16, the rotation of the main shaft 16 drives the rubber wheel 203 to rotate synchronously, which in turn drives the power wheel 202 connected to the rubber wheel 203 to rotate. The rear half of the power wheel 202 is connected to the transmission pulley 205 via a first transmission belt 204. Therefore, the rotational power of the power wheel 202 is transmitted to the transmission pulley 205 via the first transmission belt 204, causing the transmission pulley 205 to drive the transmission shaft 207 to rotate on the shaft holder 206. The drive pulley 208 connected to the rear end of the transmission shaft 207 rotates accordingly and transmits power to the driven pulley 210 via a second transmission belt 209. The driven pulley 210 drives the driven shaft 215 to rotate on the driven shaft holder 211, which in turn causes the cam 212 connected to the driven shaft 215 to begin rotating. When the cam 212 rotates, its protruding part periodically pushes the opening and closing frame 214 upwards. Under the pushing action of cam 212, the opening and closing frame 214 overcomes the elastic force of compression spring 218 and moves upward along guide frame 217. At this time, the oil outlet at the bottom of oil reservoir 216 is opened, and the lubricating oil stored in oil reservoir 216 flows into oil supply tank 213 through the oil outlet. Subsequently, the protruding part of cam 212 rotates away from the opening and closing frame 214, and the opening and closing frame 214 moves downward under the restoring force of compression spring 218, re-closing the oil outlet at the bottom of oil reservoir 216 and stopping the oil supply. This cycle repeats to achieve intermittent supply of lubricating oil. The lubricating oil flowing into oil supply tank 213 gradually permeates and flows through the relevant channels on bearing cover plate 12 to bearing cover 15, and is evenly distributed along the oil guide groove 151 provided under bearing cover 15, ultimately lubricating the friction pair between spindle 16, bearing cover 15, and bearing bottom plate 14. When the spindle 16 rotates at a higher speed, the rotation speeds of the rubber wheel 203, drive wheel 202, transmission pulley 205, transmission shaft 207, drive pulley 208, driven pulley 210, and cam 212 all increase accordingly. The number of times the cam 212 lifts the opening and closing frame 214 per unit time increases, which increases the frequency of opening the oil outlet of the oil reservoir 216 and the amount of lubricating oil supplied per unit time, in order to meet the higher lubrication requirements of the bearing under high-speed operation. Conversely, when the spindle 16 rotates at a lower speed, the rotation speed of the cam 212 also decreases, the frequency of the opening and closing frame 214 being lifted decreases, and the amount of oil supplied decreases accordingly.

[0018] In summary, this mechanism, through the close contact between the rubber wheel and the spindle, can directly sense changes in the spindle's rotational speed, achieving precise matching between lubricant supply and spindle operating status. It eliminates the need for regular manual checks and lubrication, as the lubrication mechanism automatically starts, stops, and adjusts the oil supply based on the actual operating conditions of the spindle. This reduces manual intervention, minimizes issues of untimely or excessive lubrication due to human error, saves labor costs, and makes equipment maintenance more convenient and efficient.
