Description

Technical Field

[0001] This utility model relates to the field of floating bearings, specifically a floating bearing lubrication structure and a floating bearing. Background Technology

[0002] A floating bearing is a specially designed bearing whose core function is to allow the shaft to move freely in a specific direction to accommodate thermal expansion, vibration, or misalignment during equipment operation. Cylindrical roller bearings are a type of floating bearing. They are rolling bearings with cylindrical rollers as rolling elements, mainly used to bear radial loads, but can also bear a certain amount of axial load.

[0003] In existing technology, floating bearings are widely used in the mechanical field due to their lateral movement capability. They can adapt to thermal expansion during equipment operation and have good performance. Generally, after a certain period of use, floating bearings require internal lubrication. Lubrication is usually achieved by applying lubricating oil directly to the ball surface or by injecting lubricating oil into the bearing through pre-drilled holes. Floating bearings that inject lubricating oil through pre-drilled holes typically have internal lubrication channels, allowing lubricating oil to enter the bearing smoothly. While this effectively lubricates the floating bearing, the lubricating oil quickly enters and is used up after being injected into the channels, failing to provide a continuous and effective lubrication. This increases the frequency of lubrication and maintenance. Furthermore, the lubricating oil is prone to evaporation during bearing use, further increasing the frequency of lubrication required for the floating bearing. Summary of the Invention

[0004] To overcome the shortcomings of existing technology, after the lubricating oil is injected into the lubrication channel, it quickly enters the bearing and is used, which cannot effectively and continuously inject the lubricating oil, increasing the frequency of lubrication and maintenance required. At the same time, the lubricating oil is easily evaporated during the use of the bearing, which further increases the frequency of lubrication required for the floating bearing. This utility model proposes a floating bearing lubrication structure and a floating bearing.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a floating bearing lubrication structure, including an inner ring block, an oil inlet hole is opened in the inner cavity of the inner ring block, and a lubrication mechanism is provided in the inner cavity of the inner ring block;

[0006] The lubrication mechanism includes a lubricating oil passage, which is formed in the inner cavity of the inner ring block. The inner cavity of the lubricating oil passage is connected to the inner cavity of the oil inlet hole. An expansion groove is formed in the inner cavity of the inner ring block, and the inner cavity of the expansion groove is connected to the inner cavity of the lubricating oil passage. Two annular inclined plates are fixedly connected to the inner cavity of the lubricating oil passage. The two annular inclined plates are symmetrically arranged with the central axis of the inner ring block as the center. A partition plate is fixedly connected to the inner cavity of the lubricating oil passage.

[0007] Preferably, multiple partition plates are provided, the diameters of the multiple partition plates are different, the diameters of the multiple partition plates increase sequentially from the inside to the outside, and the multiple partition plates are arranged in an alternating manner.

[0008] Preferably, each of the partition plates has a first connecting groove on its surface, and a heat sink is fixedly connected to the inner cavity of each of the first connecting grooves. The thickness and width of the heat sinks are the same.

[0009] Preferably, each of the multiple partition plates has an oil outlet filter hole on one side surface. The multiple oil outlet filter holes are arranged in a circumferential array with the center of the inner ring block as the center, and the multiple oil outlet filter holes are arranged in a honeycomb pattern.

[0010] Preferably, the inner ring block has a second connecting groove in its inner cavity, the inner cavity of the second connecting groove is connected to the inner cavity of the oil inlet hole, and a first spring is fixedly connected to the inner cavity of the second connecting groove. There are two first springs, which are staggered. A rubber sealing block is fixedly connected to the bottom of one of the first springs, and the surface of the rubber sealing block is movably engaged with the inner cavity of the oil inlet hole.

[0011] A floating bearing includes an outer ring block, an inner cavity of which is fitted with a floating bearing lubrication structure, a cage is provided in the inner cavity of the outer ring block, a flange is provided on the surface of the cage, a plurality of cylindrical rollers are rotatably connected to the inner cavity of the flange, and a mounting groove is formed on the surface of the cage, with a second spring plate fixedly connected to the inner cavity of the mounting groove.

[0012] Preferably, the inner cavity of the outer ring block is provided with a hollow groove, and a ball bearing is movably connected to the inner cavity of the hollow groove.

[0013] The advantages of this utility model are:

[0014] This invention achieves greater lubricant storage by connecting the lubricating oil channel and the expansion groove. Simultaneously, the partition plate restricts the outflow of lubricant, allowing it to flow out gradually and slowly, reducing over-lubrication caused by excessive lubricant flow at once. Furthermore, the partition plate blocks the lubricant within the lubricating oil channel, enabling long-term storage and reducing excessive evaporation of moisture. This solves the problem that lubricant, after being injected into the lubricating oil channel, quickly enters the bearing and is used, failing to provide effective and continuous lubrication and increasing the frequency of lubrication and maintenance. It also addresses the issue of lubricant easily evaporating during bearing use, further increasing the frequency of lubrication required for floating bearings. Attached Figure Description

[0023] 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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a lubrication structure for a floating bearing. (Refer to...) Figure 1 and Figure 4 A floating bearing lubrication structure and a floating bearing, including an inner ring block 1, an oil inlet hole 16 is provided in the inner cavity of the inner ring block 1, and a lubrication mechanism 6 is provided in the inner cavity of the inner ring block 1.

[0026] The lubrication mechanism 6 includes a lubrication channel 601, which is formed in the inner cavity of the inner ring block 1. The inner cavity of the lubrication channel 601 is connected to the inner cavity of the oil inlet hole 16. An expansion groove 602 is formed in the inner cavity of the inner ring block 1. The inner cavity of the expansion groove 602 is connected to the inner cavity of the lubrication channel 601. An annular inclined plate 603 is fixedly connected to the inner cavity of the lubrication channel 601. Two annular inclined plates 603 are provided. The two annular inclined plates 603 are symmetrically arranged with the central axis of the inner ring block 1 as the center. A partition plate 604 is fixedly connected to the inner cavity of the lubrication channel 601.

[0027] The oil inlet hole 16 inside the inner ring block 1 makes it convenient for workers to inject lubricating oil into the inner cavity of the inner ring block 1. Simultaneously, the expansion groove 602 is connected to the lubricating oil channel 601, and the expansion groove 602 and the lubricating oil channel 601 cooperate in a T-shape, allowing the lubricating oil channel 601 and the expansion groove 602 to store more lubricating oil. The annular inclined plate 603 installed inside the lubricating oil channel 601 allows the lubricating oil inside the expansion groove 602 to flow more smoothly out of the lubricating oil channel 601. When the lubricating oil flows out of the lubricating oil channel 601, it will... Due to the difference in the smoothness of lubricating oil flow between the lubricating oil channel 601 and the expansion groove 602, the lubricating oil is not likely to flow out too much from the lubricating oil channel 601 at once. At the same time, two annular inclined plates 603 are provided, which can effectively improve their effectiveness when in use. The partition plate 604 can further impede the lubricating oil flowing out from the lubricating oil channel 601, so that the lubricating oil can flow out gradually in multiple times and in small amounts when it flows out from the lubricating oil channel 601. It is not easy for too much lubricating oil to flow out at once due to the centrifugal force generated by the rotation of the inner ring block 1.

[0028] Reference Figure 3 and Figure 4 Multiple partition plates 604 are provided, each with a different diameter, which increases sequentially from the inside out. These partition plates are staggered, effectively obstructing the flow of lubricating oil. The lubricating oil can only flow through the gaps between the partition plates, further limiting its outflow. Furthermore, the partition plates prevent excessive oil loss at once, allowing the lubricating oil to be effectively stored within the lubricating oil channels 601 and the expansion groove 602. The partition plates also effectively reduce the rapid evaporation of moisture inside the lubricating oil, increasing its service life.

[0029] Reference Figure 4 Each of the multiple partition plates 604 has a first connecting groove 7 on its surface. Each of the multiple first connecting grooves 7 has a heat sink 8 fixedly connected to its inner cavity. The heat sink 8 has the same thickness and width. The multiple partition plates 604 can be connected to the heat sink 8 through the first connecting groove 7. The heat sink 8 can provide a certain heat dissipation effect for the lubricating oil, thereby reducing the temperature of the lubricating oil during use. The heat sink 8 can be made of nano-carbon aluminum foil, so as to reduce the impact on the inner ring block 1 during use while providing a heat dissipation effect.

[0030] Reference Figure 4 and Figure 6 Multiple oil outlet filter holes 9 are provided on one side surface of the multiple partition plates 604. The multiple oil outlet filter holes 9 are arranged in a circumferential array with the center of the inner ring block 1 as the center. The multiple oil outlet filter holes 9 are arranged in a honeycomb pattern. The arrangement of the oil outlet filter holes 9 can not only effectively prevent the partition plates 604 from excessively obstructing the flow of lubricating oil, but also the diameter of the oil outlet filter holes 9 is less than 1.5 mm. This allows the oil outlet filter holes 9 to effectively filter some impurities in the lubricating oil. At the same time, the honeycomb pattern of the oil outlet filter holes 9 can ensure that the partition plates 604 still have high strength while having oil outlet filter holes 9.

[0031] Reference Figure 4 The inner ring block 1 has a second connecting groove 17 in its inner cavity, which is connected to the inner cavity of the oil inlet hole 16. A first spring piece 10 is fixedly connected to the inner cavity of the second connecting groove 17. There are two first spring pieces 10, which are staggered. A rubber sealing block 11 is fixedly connected to the bottom of one of the first spring pieces 10. The surface of the rubber sealing block 11 is movably engaged with the inner cavity of the oil inlet hole 16. The inner ring block 1 can install and fix the first spring piece 10 through the second connecting groove 17. The rubber sealing block 11 installed at the bottom of one of the first spring pieces 10 can block and close the oil inlet hole 16, so that the oil inlet hole 16 can be in a closed state when lubricating oil is not needed. At the same time, the setting of the first spring piece 10 can apply elastic pressure to the rubber sealing block 11, so that the rubber sealing block 11 can be used smoothly and has an elastic reset function.

[0032] Working principle: When lubricating oil needs to be injected into the inner ring block 1, the operator can insert the lubricating oil injection pipe into the oil inlet 16, and lift the first spring plate 10 during insertion. After the oil injection pipe is successfully inserted into the oil inlet 16, lubricating oil can be injected into the lubricating oil passage 601. After the oil injection is completed, the oil injection pipe can be removed from the oil inlet 16. At this time, the first spring plate 10 can reset itself through its own elasticity, and the rubber sealing block 11 can be reinserted into the oil inlet 16. Afterwards, when the inner ring block 1 is used... The lubricating oil inside the lubricating oil channel 601 and the expansion groove 602 will flow out from the inside of the lubricating oil channel 601 due to the centrifugal force generated when the inner ring block 1 rotates. When flowing out, it will pass through multiple partition plates 604 and be blocked by the partition plates 604. At the same time, it will be filtered by the oil outlet filter hole 9, so that the lubricating oil can flow out from the inside of the inner ring block 1 gradually and slowly, reducing the situation of excessive lubricating oil flowing out at one time and causing lubricating oil waste. At the same time, the partition plates 604 can also reduce the excessive water vapor evaporation of lubricating oil inside the lubricating oil channel 601 and the expansion groove 602.

[0033] A floating bearing includes an outer ring block 2, a floating bearing lubrication structure installed in the inner cavity of the outer ring block 2, a cage 3 provided in the inner cavity of the outer ring block 2, a retainer 4 provided on the surface of the cage 3, a cylindrical roller 5 rotatably connected to the inner cavity of the retainer 4, a plurality of cylindrical rollers 5 are provided, and a mounting groove 12 is opened on the surface of the cage 3, and a second spring piece 13 is fixedly connected to the inner cavity of the mounting groove 12.

[0034] The inner ring block 1 can be connected to the flange bracket 4 via the cage 3. The cylindrical rollers 5 connected inside the flange bracket 4 can cooperate with the inner ring block 1 and the outer ring block 2, allowing the inner ring block 1 and the outer ring block 2 to be used smoothly. The inner ring block 1, the outer ring block 2, the cage 3, the flange bracket 4, and the cylindrical rollers 5 can form the cylindrical roller bearing body. Cylindrical roller bearings are existing technology in this field, so they will not be described in detail here. The cage 3 can be connected to the second spring plate 13 via the mounting groove 12. When the flange bracket 4 is connected to the surface of the cage 3, it can compress the second spring plate 13. After the flange bracket 4 is connected to the cage 3, the second spring plate 13 can be reset by its own elasticity, which plays a limiting role on the flange bracket 4, making the flange bracket 4 stable enough during use and increasing the stability and stability of the flange bracket 4 after the cage 3 and the flange bracket 4 are connected.

[0035] Reference Figure 3 and Figure 5 The inner cavity of the outer ring block 2 is provided with a hollow groove 14, and a ball 15 is movably connected to the inner cavity of the hollow groove 14. The outer ring block 2 can connect the ball 15 through the hollow groove 14. The setting of the ball 15 can reduce the friction between the ball 15 and the inside of the outer ring block 2 when the cylindrical roller 5 is rotating and in use, thereby increasing the effect of the cylindrical roller 5 in use.

[0036] Working principle: When the side guard 4 is connected to the retainer 3, the side guard 4 can be inserted into the surface of the retainer 3 first. At this time, the side guard 4 will press the second spring 13. When the side guard 4 is connected to the retainer 3, the second spring 13 will reset through its own elasticity, and at the same time, it will restrict and reinforce the side guard 4.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
