Description

Technical Field

[0001] This utility model relates to the field of bearings, and more specifically, to a lubrication device for an upper bearing component. Background Technology

[0002] Bearings are essential components in modern machinery. Their main function is to support rotating shafts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Based on the different frictional properties of the moving elements, they can be classified into rolling bearings and sliding bearings, and are widely used in many fields such as mechanical transmission, automobiles, and aerospace.

[0003] The prior art disclosed in patent publication (announcement) number CN213576747U is a lubrication device for an upper bearing component, including a base plate, a support leg provided at the bottom of the base plate, an oil receiving groove provided in the middle of the base plate, a rotating shaft provided in the middle of the oil receiving groove, a drive motor provided at the bottom of the rotating shaft, a support plate provided at the top of the rotating shaft, and fixing components provided on both sides of the support plate.

[0004] The aforementioned patent document discloses a lubrication device for upper bearing components. While it solves the problems of lubricant waste and the fact that existing devices are only suitable for lubricating a single type of bearing, its shortcomings are: When the aforementioned patented device is in use, the fixing component relies on an electric push rod and a fixing block to fix the bearing component, which depends on linear motion and is a single method. When dealing with components of different shapes and sizes, especially irregular parts, it is difficult to achieve a perfect fit and fixation, which can easily cause the components to shake and shift during lubrication, affecting the lubrication effect and equipment operation.

[0005] Furthermore, although the aforementioned patent includes an oil collection trough to collect leaked lubricating oil, the filter screen is located above the oil collection trough. Impurities such as metal shavings and dust that may be mixed in with the lubricating oil can easily accumulate and clog the filter screen, leading to a further decrease in filtration efficiency and even affecting the normal circulation of the lubricating oil.

[0006] Therefore, we have made improvements to this and proposed a lubrication device for upper bearing components. Utility Model Content

[0025] To address the technical problems in the background art, the following lubrication device for the upper bearing component is provided: Combination Figure 1 - Figure 5As shown, the present invention provides a lubrication device for an upper bearing component, including a base box 1. A groove 2 is formed on the upper surface of the base box 1, and a fixing mechanism 3 is provided inside the groove 2. A fixing rod 4 is fixedly installed on one side of the upper surface of the base box 1, and an electric push rod 5 is fixedly installed on one side of the fixing rod 4. A fixing block 6 is fixedly installed on the telescopic end of the electric push rod 5. A lubrication mechanism 7 is provided on the lower side of the fixing block 6. A filtering mechanism 8 is provided on the surface of the groove 2. The fixing mechanism 3 includes a rotating rod 301, which is rotatably connected to the surface of the groove 2. A sliding groove 302 is formed inside the rotating rod 301, and sliding blocks 303 are slidably connected to the upper and lower sides of the sliding groove 302. Support rods 304 are hinged to the two sides of the two sliding blocks 303, and support plates 305 are hinged to the other ends of the two support rods 304 on the same side. The support plates 305 are L-shaped, and rubber pads 306 are fixedly connected to the outer surface of the support plates 305.

[0026] In this embodiment: the base box 1 serves as the basic support structure of the device, and the groove 2 on its upper surface facilitates the collection of lubricating oil. In the recessed fixing mechanism 3, the rotating rod 301 can rotate on the surface of the groove 2, facilitating the rotation of the bearing component and lubrication. The sliding groove 302 inside the rotating rod 301, and the sliding blocks 303 slidably connected on both sides therein, constitute an adjustable moving structure. The support rods 304 hinged on both sides of the two sliding blocks 303 cooperate with the L-shaped support plate 305 hinged on the same side. When the sliding blocks 303 move in the sliding groove 302, they can drive the support plate 305 to move, thereby adapting to upper bearing components of different sizes. The rubber pad 306 fixedly connected to the outer surface of the support plate 305 not only increases the friction between the support plate and the upper bearing component, but also plays a buffering and protective role, preventing damage to the component during the fixing process and ensuring that the upper bearing component remains stable during lubrication.

[0027] In a preferred embodiment, a threaded rod 307 is rotatably connected inside the slide groove 302, and the thread directions at both ends of the threaded rod 307 are opposite. Both sliding blocks 303 are threadedly connected to both ends of the threaded rod 307.

[0028] In this embodiment, a threaded rod 307 with opposite thread directions is provided inside the slide groove 302. Two sliding blocks 303 are threadedly connected to both ends of the threaded rod 307. When the threaded rod 307 is rotated, the two sliding blocks 303 will move synchronously in opposite directions along the slide groove 302 due to the opposite thread directions, thereby driving the support plate 305 to extend and retract, thus fixing bearing components of different sizes.

[0029] In a preferred embodiment, a cavity 308 is provided inside the bottom end of the rotating rod 301, and a first motor 309 is fixedly installed inside the cavity 308. The output end of the first motor 309 is fixedly connected to one end of the threaded rod 307.

[0030] In this embodiment, a first motor 309 fixedly installed inside the cavity 308 serves as the power source, with its output end tightly connected to one end of the threaded rod 307. When the first motor 309 is started, the motor output end drives the threaded rod 307 to rotate. Based on the opposite threads at both ends of the threaded rod 307 engaging with the threads of the sliding blocks 303, the two sliding blocks 303 are driven to move synchronously in opposite directions, ultimately achieving the extension and retraction of the support plate 305 to accommodate and fix upper bearing components of different sizes, thus improving the ease of operation of the device.

[0031] In a preferred embodiment, a sealing box 310 is fixedly installed on the top of the bottom box 1, and a second motor 311 is provided inside the sealing box 310. The second motor 311 is fixedly installed on the top of the bottom box 1, and the output end of the second motor 311 is fixedly connected to the lower end of the rotating rod 301.

[0032] In this embodiment, the sealing box 310 provides a reliable installation and protective environment for the second motor 311, effectively isolating it from external dust, lubricating oil, and other impurities, ensuring stable motor operation. When the second motor 311 starts, power is transmitted to the rotating rod 301 through the output end, driving the rotating rod 301 to rotate in a set direction and speed, thereby causing the upper bearing component fixed on the rotating rod 301 to rotate, so that the lubricating oil can evenly and comprehensively cover the bearing component, greatly improving the lubrication effect and the degree of automation of the device.

[0033] In a preferred embodiment, the lubrication mechanism 7 includes a connector 701, which is fixedly installed on the lower surface of the fixing block 6. An oil injector 702 is fixedly installed inside the connector 701. A submersible pump 703 is fixedly installed at the bottom of the base box 1. An oil suction pipe 704 and an oil delivery pipe 705 are respectively connected to the two sides of the submersible pump 703. The other end of the oil delivery pipe 705 is connected to the oil injector 702, and the oil delivery pipe 705 is a flexible hose.

[0034] In this embodiment: the connector 701 is installed on the lower surface of the fixing block 6, providing a reliable fixing base for the nozzle 702. The submersible pump 703 is fixed to the bottom of the base box 1, and draws lubricating oil from a suitable position through the oil extraction pipe 704, and then delivers the lubricating oil to the nozzle 702 through the oil delivery pipe 705, so that the nozzle 702 can spray the lubricating oil onto the upper bearing component. At the same time, the use of the electric push rod 5 makes it easy to adjust the position of the nozzle 702 according to the different sizes of the upper bearing component.

[0035] In a preferred embodiment, the filter mechanism 8 includes an oil leakage hole 801, which is formed on the surface of the groove 2. The upper surface of the groove 2 is provided with an installation groove 802, and an installation ring 803 is threadedly connected to the inside of the installation groove 802. A filter screen bag 804 is fixedly installed on the lower surface of the installation ring 803.

[0036] In this embodiment: the oil leakage hole 801 on the surface of the groove 2 provides a channel for the return of lubricating oil, allowing excess lubricating oil to flow smoothly back into the bottom box 1 for collection; the mounting groove 802 on the upper surface of the groove 2 cooperates with the mounting ring 803 with internal thread connection to form a convenient detachable structure; the filter bag 804 fixedly installed on the lower surface of the mounting ring 803 can effectively intercept bearing debris, impurities and other contaminants carried in the lubricating oil, preventing these impurities from re-entering the lubrication system and affecting the lubrication effect and the service life of the bearing.

[0037] When the filter bag 804 accumulates a lot of impurities, simply unscrew the mounting ring 803 from the mounting groove 802 to easily clean or replace the filter bag 804, ensuring that the filter mechanism 8 always maintains good filtration performance.

[0038] In a preferred embodiment, the upper surface of the mounting ring 803 is provided with a groove 805, and a handle 806 is rotatably connected inside the groove 805.

[0039] In this embodiment: when the filter bag 804 needs to be cleaned or replaced, simply rotate the handle 806 out of the slot 805. By rotating the handle 806, the mounting ring 803 can be easily rotated out, and the filter bag 804 can be processed accordingly, which greatly improves the maintenance efficiency of the filter mechanism 8. When not in use, the handle 806 can be hidden in the slot 805.

[0040] Specifically, the working principle of this solution is as follows: In use, first, the upper bearing component is fitted onto the support plate 305 of the fixing mechanism 3. Then, the first motor 309 is started, and its output drives the threaded rod 307 to rotate. Because the threads at both ends of the threaded rod 307 are opposite, the two sliding blocks 303 move synchronously in opposite directions. This movement, via the support rod 304, moves the support plate 305, providing internal support and fixation for the bearing component. This also allows for the fixing of components of different sizes. The rubber pad 306 increases friction and provides cushioning protection. Next, the second motor 311 is started, and its output drives the rotating rod 301 to rotate, causing the upper bearing component to rotate.

[0041] Meanwhile, the submersible pump 703 draws lubricating oil from the bottom tank 1 through the oil extraction pipe 704, and delivers it to the oil spray nozzle 702 via the oil delivery pipe 705, spraying it evenly onto the rotating bearing components for comprehensive lubrication. Excess lubricating oil flows back to the bottom tank 1 through the oil leakage hole 801 on the surface of the groove 2, where the filter bag 804 intercepts bearing debris and impurities. When the filter bag 804 accumulates a lot of impurities, the handle 806 is turned out of the groove 805 on the upper surface of the mounting ring 803, and the mounting ring 803 is turned out of the mounting groove 802, allowing the filter bag 804 to be cleaned or replaced, ensuring filtration performance. The entire device has a high degree of automation and good lubrication effect.

[0042] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
