[0001] This utility model relates to the field of bearing assembly technology, and specifically to a bearing sleeve that is easy to assemble. Background Technology

[0002] A bearing sleeve, also known as a bearing housing or bushing, is a housing specifically designed to house and secure a bearing. It does not contain rolling elements itself, but rather provides a precise, stable, and robust mounting environment for standard rolling bearings.

[0003] Utility model patent CN221347637U discloses a bearing housing that facilitates lubrication. It includes a base plate with mounting holes on both the front and rear sides of the top of the base plate. A lower bearing housing is fixedly mounted on the top of the base plate. A limiting component is fixedly mounted on the top right side of the lower bearing housing. An upper bearing housing is movably mounted on the top of the lower bearing housing via a rotating shaft. A bearing body is movably mounted on the top of the lower bearing housing. A lubrication component is fixedly mounted inside the upper bearing housing.

[0004] Although the above technical solution can facilitate the rotation of the bearing in the bearing housing by injecting lubricating oil on the bearing surface, the bearing is the important connecting component. The method of injecting lubricating oil on the bearing surface cannot allow the lubricating oil to enter the bearing. As a result, the bearing cannot maintain lubrication and rotation during long-term use, which leads to wear and damage due to lack of lubrication. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a bearing sleeve that is easy to assemble, which can effectively solve the problem that the method of filling the bearing surface with lubricating oil in the existing technology does not allow the lubricating oil to enter the bearing, resulting in the bearing not being able to maintain lubrication and rotate during long-term use, causing the bearing to lack lubrication and resulting in wear and damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a bearing sleeve that is easy to assemble, including an upper bearing sleeve and a lower bearing sleeve. The upper bearing sleeve is disposed at the bottom of the lower bearing sleeve. A transmission rod is inserted between the upper bearing sleeve and the lower bearing sleeve. A first extension plate is installed on both sides of the upper bearing sleeve and the lower bearing sleeve. Fastening bolts are provided on both sides of the top of the first extension plate. The fastening bolts extend to the bottom of the first extension plate. A baffle plate is installed on both the front and back of the lower bearing sleeve. A fitting block is installed between the two sets of baffle plates. A liquid storage cavity is opened inside the fitting block. A first connecting pipe is connected to the bottom of the inner wall of the liquid storage cavity. A squeezing frame is slidably installed on the bottom of the inner wall of the liquid storage cavity.

[0007] Furthermore, a fixing ring is installed on the front of the baffle plate, and a second connecting pipe is connected to the top of the fixing ring. The end of the second connecting pipe is connected to the liquid storage chamber, and a guide plate is installed on the inner wall of the liquid storage chamber. The guide plate is located at the bottom of the second connecting pipe.

[0008] Furthermore, a first notch is formed on the surface of the transmission rod, a connecting ring is installed on the inner wall of the blocking plate, a second notch is formed on the inner wall of the connecting ring, a spline is inserted into the inner wall of the first notch, and the spline is engaged inside the second notch.

[0009] Furthermore, a second extension plate is installed between the two sets of the blocking plates, and a through hole is provided at the top of the second extension plate, the through hole being located at the bottom of the fastening bolt.

[0010] Furthermore, the inner wall of the fixed ring is provided with a movable groove, and a pressing block is inserted into the movable groove, with the top of the pressing block being inclined.

[0011] Furthermore, a first tension spring is installed on the inner wall of the movable groove, and a first mounting plate is installed on the side of the extrusion block, with the end of the first tension spring fixedly connected to the bottom of the first mounting plate.

[0012] Furthermore, a squeezing plate is inserted into the interior of the movable groove, the end of the squeezing plate extends into the interior of the liquid storage chamber, and the end of the squeezing plate is fixedly connected to the side of the squeezing frame.

[0013] Furthermore, a second mounting plate is installed on the surface of the extrusion plate, and a first spring is installed on the inner wall of the movable groove, with the end of the first spring fixedly connected to the second mounting plate.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art: I. This utility model, by setting up components such as a first extension plate, fastening bolts, a blocking plate, a bonding block, a liquid storage chamber, a first connecting pipe, and a squeezing frame, allows the first extension plate to be connected using fastening bolts, thereby enabling the upper bearing sleeve and the lower bearing sleeve to cooperate in installing the bearing. When the squeezing frame moves, it can squeeze the lubricating oil in the liquid storage chamber, allowing the lubricating oil to enter the interior of the bearing through the bearing's sealing lip, thus adding lubricating oil to the bearing. This reduces bearing friction and improves the bearing's service life.

[0015] II. By setting up components such as a second connecting pipe, spline, extrusion block and extrusion plate, the present invention can deliver lubricating oil through the second connecting pipe, so that when the spline is driven to rotate by the transmission rod, it will squeeze the extrusion block, which can squeeze the extrusion plate, and the extrusion plate can push the extrusion frame, so that the extrusion frame can push the lubricating oil when it moves, and can squeeze out the lubricating oil for lubrication.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] See attached document Figures 1-4 A bearing sleeve for easy assembly includes an upper bearing sleeve 1 and a lower bearing sleeve 2. The upper bearing sleeve 1 is located at the bottom of the lower bearing sleeve 2. A transmission rod 3 is inserted between the upper bearing sleeve 1 and the lower bearing sleeve 2. A first extension plate 4 is installed on both sides of the upper bearing sleeve 1 and the lower bearing sleeve 2. Fastening bolts 5 are provided on both sides of the top of the first extension plate 4, extending to the bottom of the first extension plate 4. A baffle plate 6 is installed on both the front and back of the lower bearing sleeve 2. A fitting block 7 is installed between the two sets of baffle plates 6. A liquid storage cavity 8 is opened inside the fitting block 7. The bottom of the inner wall of the liquid storage cavity 8 is... The first connecting pipe 9 is connected to the bearing. A squeezing frame 10 is slidably installed at the bottom of the inner wall of the liquid storage chamber 8. After the bearing is placed on top of the lower bearing sleeve 2, the upper bearing sleeve 1 is fitted with the lower bearing sleeve 2 and the fastening bolt 5 is installed to restrict the first extension plate 4. The bearing can be installed, and the moving squeezing block 20 squeezes the lubricating oil in the liquid storage chamber 8 and discharges it from the first connecting pipe 9 to the side of the bearing. This allows the lubricating oil to enter the bearing through the bearing's sealing lip, thereby adding lubricating oil to the bearing so that it can be kept lubricated.

[0022] See attached document Figures 1-4A fixing ring 11 is installed on the front of the baffle plate 6. The top of the fixing ring 11 is connected to a second connecting pipe 12. The end of the second connecting pipe 12 is connected to the liquid storage chamber 8. A guide plate 13 is installed on the inner wall of the liquid storage chamber 8. The guide plate 13 is located at the bottom of the second connecting pipe 12. The second connecting pipe 12 is installed through the fixing ring 11 so that lubricating oil can be transported to the liquid storage chamber 8 through the second connecting pipe 12 for temporary storage of lubricating oil. The guide plate 13 can guide the lubricating oil entering the liquid storage chamber 8. A first notch 14 is opened on the surface of the transmission rod 3. A connecting ring 15 is installed on the inner wall of the baffle plate 6. The inner wall of the connecting ring 15 is provided with a second notch 16, and a spline 17 is inserted into the inner wall of the first notch 14. The spline 17 is snapped into the inside of the second notch 16. By placing the spline 17 into the first notch 14 and the second notch 16, the connecting ring 15 can be connected to the transmission rod 3 through the spline 17, so as to facilitate the installation of the baffle plate 6. It is worth noting that the surfaces of the first connecting pipe 9 and the second connecting pipe 12 are both unidirectional, so that the lubricating oil is delivered to the bearing through the first connecting pipe 9, and the unidirectional setting of the second connecting pipe 12 can prevent the lubricating oil in the liquid storage chamber 8 from being squeezed out through the second connecting pipe 12.

[0023] In addition, a second extension plate 18 is installed between the two sets of baffle plates 6. The top of the second extension plate 18 has a through hole located at the bottom of the fastening bolt 5. The fastening bolt 5 can be passed through the through hole of the second extension plate 18, and the second extension plate 18 can be installed on the surface of the first extension plate 4, thereby facilitating the installation of the baffle plate 6.

[0024] See attached document Figures 1-4 The inner wall of the fixed ring 11 is provided with a movable groove 19, and a pressing block 20 is inserted into the movable groove 19. The top of the pressing block 20 is inclined. A first tension spring 21 is installed on the inner wall of the movable groove 19. A first mounting plate 22 is installed on the side of the pressing block 20. The end of the first tension spring 21 is fixedly connected to the bottom of the first mounting plate 22, which can press the pressing block 20 when the spline 17 rotates, so that the pressing block 20 can move upward into the movable groove 19. The installed first tension spring 21 can drive the pressing block 20 downward through the first mounting plate 22 after the pressing block 20 is separated from the spline 17, so as to reset the pressing block 20 downward.

[0025] See attached document Figures 1-4An extrusion plate 23 is inserted into the interior of the movable groove 19. The end of the extrusion plate 23 extends into the interior of the liquid storage chamber 8. The end of the extrusion plate 23 is fixedly connected to the side of the extrusion frame 10. A second mounting plate 24 is installed on the surface of the extrusion plate 23. A first spring 25 is installed on the inner wall of the movable groove 19. The end of the first spring 25 is fixedly connected to the second mounting plate 24. This allows the extrusion block 20 to extrude the extrusion plate 23 when it moves upward. When the extrusion plate 23 is extruded and moved, it drives the extrusion frame 10 to move, thereby facilitating the extrusion frame 10 to extrude the lubricating oil in the liquid storage chamber 8. This facilitates the extrusion of the lubricating oil from the first connecting pipe 9 to the side of the bearing, thus facilitating the lubrication of the bearing.

[0026] Working principle: The rear-side blocking plate 6 is fitted onto the surface of the transmission rod 3. Then, the bearing is fitted onto the surface of the transmission rod 3, positioned in front of the blocking plate 6. The transmission rod 3 is placed on top of the lower bearing sleeve 2, with the bearing positioned on top of the lower bearing sleeve 2. Next, the upper bearing sleeve 1 is placed on top of the lower bearing sleeve 2, aligning the first extension plate 4 with the second extension plate 18. The rear-side blocking plate 6 is then moved forward, bringing its front surface into contact with the back surfaces of the lower bearing sleeve 2 and the upper bearing sleeve 1. The contact block 7 is then placed into contact with the back surface of the bearing, causing the second extension plate 18, located on the front surface of the rear blocking plate 6, to extend to both sides of the first extension plate 4. This initially restricts the first extension plate 4 and... The through hole on the surface of the extension plate 18 is aligned with the hole on the surface of the first extension plate 4 for mounting the fastening bolt 5. After the fastening bolt 5 is installed, the second extension plate 18 is restricted, thereby installing the rear blocking plate 6. Then, the front blocking plate 6 is fitted onto the surface of the transmission rod 3, so that the front blocking plate 6 moves to the front of the bearing. The back of the front blocking plate 6 and the mating block 7 can contact the front of the bearing. The front blocking plate 6 is then installed using the fastening bolt 5. By installing the spline 17 into the first notch 14 and the second notch 16, the front and rear blocking plates 6 can be installed so that the two sets of mating blocks 7 cooperate to install the bearing, which facilitates the assembly of the bearing.

[0027] When the transmission rod 3 is driven to rotate, it will drive the spline 17 to rotate. When the spline 17 rotates, it will squeeze the extrusion block 20, causing the extrusion block 20 to move into the mounting groove. When the extrusion block 20 moves upward, it will squeeze the extrusion plate 23, which can push the extrusion frame 10. The extrusion frame 10 can push the lubricating oil in the liquid storage chamber 8 to squeeze, so that the lubricating oil can be delivered to the side of the bearing through the first connecting pipe 9, so that the lubricating oil can enter the bearing through the bearing's sealing gasket, thereby facilitating the lubrication of the bearing. After the second connecting pipe 12 is connected to the external oil source, the first spring 25 and the first tension spring 21 will drive the extrusion plate 23 and the extrusion block 20 to reset. When the extrusion frame 10 resets, a negative pressure can be generated in the liquid storage chamber 8, which will draw the lubricating oil from the external pipe through the second connecting pipe 12, thereby facilitating the lubrication of the bearing.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
