Description

Technical Field

[0001] The present invention relates to the technical field of two-way thrust tapered roller bearings with inner liners, and specifically to a two-way thrust tapered roller bearing with an inner liner and a manufacturing method thereof. Background Art

[0002] A two-way thrust tapered roller bearing is a rolling bearing used to bear axial loads. Its design features make it perform excellently in many industrial applications. A two-way thrust tapered roller bearing is mainly designed to bear axial loads, which usually act on the axis of the bearing rather than radially. They are particularly suitable for occasions that need to bear axial forces from two directions simultaneously. Due to their structural characteristics, such bearings have high rigidity and can maintain stability and precision under heavy loads and impact conditions. A two-way thrust tapered roller bearing has a certain self-aligning ability, which means it can work normally when the shaft has a slight deviation. This is an important advantage for installation and maintenance. When running at high speed, the cage is usually made of copper alloy material, which has good thermal conductivity and can quickly dissipate heat, thereby reducing hydrodynamic losses. The two-way thrust tapered roller bearing with a cage is of a split design, enabling the washer, roller, and cage assembly to be easily separated for installation, facilitating maintenance and replacement of parts. Generally speaking, two-way thrust tapered roller bearings are an indispensable part of modern mechanical equipment, and their design and functions are crucial for ensuring the efficient and reliable operation of mechanical systems.

[0003] In the use of existing two-way thrust tapered roller bearings, their free clearance rings are generally fixedly matched. This makes it that when the bearing instantaneously bears an excessive load force during operation, it will affect the normal use of the bearing and also reduce the service life of the bearing. During operation, additional stress and heat will be generated inside the bearing, leading to unstable operation of the equipment. Then, during the operation of the bearing, lubricating oil needs to be added regularly to ensure that the bearing can reduce friction and dissipate heat better when rotating. However, when adding the lubricating oil, the bearing often needs to be disassembled, which will affect the normal operation of the equipment. At the same time, disassembling the bearing is rather cumbersome, time-consuming, and laborious. Therefore, we have proposed a two-way thrust tapered roller bearing with an inner liner and a manufacturing method thereof. Summary of the Invention

A free clearance ring is installed on the inner wall of the outer ring. Finally, cover and fix the inner ring, and then perform assembly. The assembled bearing needs to be strictly inspected and tested to ensure that it meets the actual design requirements and usage standards.

[0022] Compared with the prior art, the present invention provides a two-way thrust tapered roller bearing with a lining sleeve and a manufacturing method, having the following beneficial effects:

[0023] 1. A bidirectional thrust tapered roller bearing with an inner sleeve and a manufacturing method thereof, wherein a rotating shaft, a tapered roller bearing assembly, an outer ring, an adjusting assembly, etc. are arranged. When in use, the rotating shaft is connected to the equipment, and then two sets of tapered roller bearing assemblies are installed on the inner wall of the outer ring. The inner wall of the outer ring is provided with a first free gap ring and a second free gap ring, wherein the first free gap ring is fixed on the inner wall of the outer ring, and the second free gap ring is slidably arranged in the inner wall of the annular groove in the first free gap ring. Then, four sets of through holes are equidistantly opened on the outer wall of the outer ring, wherein A first slider is provided for sliding on the inner wall, and a second free gap ring is connected to one end of the first slider.

A pressure block is provided at the other end of the first slider, and is connected to the third spring through the second slider. Therefore, when the load borne by the bearing suddenly increases, the two groups of tapered roller bearings will absorb a part of it first, and the rest will be absorbed by the sliding of the second free gap ring.

[0024] 2. The bidirectional thrust tapered roller bearing with an inner sleeve and the manufacturing method thereof are provided with a rotating shaft, a tapered roller bearing assembly, an outer ring, an oil replenishing assembly, etc. When the bearing needs to be lubricated during use, the operator can quickly add the lubricating oil stored in the first oil tank and the second oil tank to the inside of the bearing by moving the first lever and the second lever. Specifically, when the first lever and the second lever are moved, the first rack and the second rack will slide. When sliding, the second push plate and the first push plate fixed at both ends of the first rack and the second rack will generate suction force, thereby sucking the second oil suction pipe and the baffle in the first oil suction pipe apart. At this time, the lubricating oil in the first oil tank and 90 will flow into the first oil delivery pipe and the second oil delivery pipe. Then, the second lever and the first lever are released. At this time, under the rebound of the first spring and the second spring, the lubricating oil in the first oil delivery pipe and the second oil replenishing pipe will be added to the inside of the bearing and lubricated. Through the above design, it is possible to quickly add lubricant, which is convenient, fast, time-saving and labor-saving.

[0025] 3. A bidirectional thrust tapered roller bearing with an inner sleeve and a manufacturing method thereof, by setting a first oil tank and a second oil tank, can store lubricating oil therein when in use. When the bearing needs to be lubricated, the lubricating oil can be quickly added to the bearing by moving the first lever and the second lever. When the lubricating oil does not need to be added, the lubricating oil will be stored in the first oil tank and the second oil tank. The above design can realize rapid extraction and storage of the lubricating oil, which is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a two-way thrust tapered roller bearing with a lining sleeve.

[0039] In a typical implementation manner of the present application, as Figures 1-10 shown, a two-way thrust tapered roller bearing with a lining sleeve includes a rotating shaft 1, which is mechanically connected to the equipment, two sets of tapered roller bearing assemblies 2, which are symmetrically installed on the outer wall of the rotating shaft 1 to bear the load, an outer ring 3, in which the tapered roller bearing assemblies 2 are installed to fix and separate the tapered roller bearings, and an adjusting assembly 4, which is used to adaptively adjust the free clearance ring inside to meet the requirements of different working conditions;

[0040] When in use, first install the rotating shaft 1 on the equipment, and then sequentially place the two sets of tapered roller bearing assemblies 2 into the outer ring 3. There is a first free clearance ring 6 and a second free clearance ring 29 inside the outer ring 3. Here, it should be mentioned that the main function of the free clearance ring in the two-way thrust tapered roller bearing is to adjust the free clearance of the two sets of tapered roller bearing assemblies 2 to ensure flexibility during the operation of the bearing, thereby reducing friction and wear. In the present invention, the second free clearance ring 29 is slidably arranged on the inner wall of the first free clearance ring 6, and the width of the free clearance ring is adaptively adjusted through the adjusting assembly 4 to facilitate achieving a suitable clearance;

[0041] As a preferred implementation manner in this embodiment, the adjusting assembly 4 includes four through holes 7 equidistantly opened on the right side of the outer wall of the outer ring 3. The inner walls of the four through holes 7 are all slidably provided with first sliders 30. The right outer walls of the four first sliders 30 are all fixed with pressing blocks 31. The right sides of the four pressing blocks 31 are all fixed with second sliders 32. Four fixing blocks 34 are equidistantly fixed on the left side of the outer wall of the outer ring 3. The inner walls of the four fixing blocks 34 are all hollow-designed. The inner walls of the four fixing blocks 34 are all fixedly connected with third springs 33. The left ends of the four third springs 33 are all connected to the right outer wall of the second slider 32;

[0042] Further, in the above solution, after connecting the rotating shaft 1 to the device, at this time, two sets of tapered roller bearing assemblies 2 are assembled inside the outer ring 3. Four sets of through holes 7 are equidistantly formed in the outer wall of the outer ring 3. A first slider 30 is fixed to the outer wall of the inner ring of a set of tapered roller bearings. The first slider 30 is slidably arranged on the inner wall of the through hole 7. At the same time, four sets of fixing blocks 34 are equidistantly fixed on the outer wall of the outer ring 3 at the positions of the through holes 7. The main purpose is to cooperate with the first slider 30. A third spring 33 is arranged inside the fixing block 34. Its main material is steel. At the same time, the left end of the third spring 33 is connected to a second slider 32. The second slider 32 is connected to the first slider 30 through the rotating shaft 1. When the stress borne by the tapered roller bearing reaches the maximum, at this time, the tapered roller bearing inside the tapered roller bearing assembly 2 will apply pressure to the second free clearance ring 29. Note that the pressure is the remaining stress after the tapered roller bearing absorbs the maximum stress. When the second free clearance ring 29 receives the stress from the tapered roller bearing, it will slide to the right at this time. At the same time, the four sets of pressing blocks 31 will gradually compress the third spring 33 until the free clearance ring reaches the ideal thickness, so as to reduce the impact force directly acting on the tapered roller bearing and the raceway, thereby extending the service life of the tapered roller bearing. At the same time, this design can ensure that when the tapered roller bearing bears the ultimate load, the structure of the bearing itself remains stable, avoiding damage to the internal parts of the bearing due to excessive stress, and thus affecting the normal operation of the device;

[0043] In this embodiment, the tapered roller bearing assembly 2 includes two sets of bases 26 rotatably and coaxially fixed on the outer wall of the rotating shaft 1. An inner ring 27 is fixed to the inner wall of the base 26. A number of tapered rollers 28 are rotatably connected equidistantly inside the inner ring 27. A first free clearance ring 6 is fixed to the left side of the inner wall of the outer ring 3. An annular groove is formed on the right outer wall of the first free clearance ring 6. A second free clearance ring 29 is slidably arranged on the inner wall of the annular groove. The four sets of first sliders 30 pass through the through holes 7 and are fixed to the second free clearance ring 29;

[0044] In the above structural design, the tapered roller bearing assembly 2 is a conventional structural design. In the present invention, the original design is still adopted without any change. Therefore, it will not be described in detail here.

[0045] Embodiment 2. In the present invention, an oil replenishing component 5 is arranged on the outer wall of the outer ring 3. Its main function is to reduce the friction and wear of the tapered roller bearing during use. Because the lubricating oil can form an oil film on the contact surface between the rolling elements and the raceway of the bearing, thus separating the contact surfaces, reducing the direct contact between metals, and further reducing the friction and wear. At the same time, the lubricating oil can take away most of the frictional heat inside the bearing, preventing the tapered roller bearing from being damaged due to overheating, and thus affecting the normal operation of the device. The specific structure of the oil replenishing component 5 in the present invention is as follows;

[0046] As a preferred implementation manner in this embodiment, the oil replenishing assembly 5 is used to lubricate the two sets of tapered roller bearing assemblies 2 inside the outer ring 3, so as to reduce the frictional force and enhance the heat dissipation effect. The oil replenishing assembly 5 includes an arc-shaped fixing block 14 fixed to the outer wall of the outer ring 3. The inner wall of the arc-shaped fixing block 14 is designed to be hollow. A first oil tank 8 is fixed to the upper side of the inner wall of the arc-shaped fixing block 14, and a second oil tank 9 is fixed to the lower side of the inner wall of the arc-shaped fixing block 14. Two sets of rectangular through holes are symmetrically formed in the front and rear outer walls of the arc-shaped fixing block 14. A connecting rod is fixed in the center of the inner wall of the arc-shaped fixing block 14. A gear 35 is rotatably connected to the outer wall of the connecting rod. A first oil delivery pipe 11 is fixedly connected to the inner wall of the rectangular through hole on the front side, and a second oil delivery pipe 16 is fixedly connected to the inner wall of the rectangular through hole on the rear side. A first rack 21 is slidably arranged in the first oil delivery pipe 11, and a second rack 22 is slidably arranged in the inner wall of the second oil delivery pipe 16. An elastic assembly for realizing their sliding is installed at the tops of the first rack 21 and the second rack 22. The elastic assembly includes a second toggle lever 19 fixed to the top of the first rack 21, a first toggle lever 13 fixed to the top of the second rack 22. A second spring 18 is fixed to the rear side of the second toggle lever 19. One end of the second spring 18 away from the second toggle lever 19 is fixed to the inner wall of the arc-shaped fixing block 14. A first spring 12 is fixed to the front end of the first toggle lever 13. One end of the first spring 12 away from the first toggle lever 13 is fixed to the inner wall of the arc-shaped fixing block 14. The first rack 21 meshes with the gear 35, and the second rack 22 meshes with the gear 35. A second oil suction pipe 20 is fixedly connected to the right side of the first oil tank 8, and the right side of the second oil suction pipe 20 is connected to the first oil delivery pipe 11. A first oil suction pipe 15 is fixed to the left side of the second oil tank 9, and the left side of the first oil suction pipe 15 is connected to the second oil delivery pipe 16. A first oil replenishing pipe 10 is fixed to the bottom of the first oil delivery pipe 11, and a second oil replenishing pipe 17 is fixed to the bottom of the second oil delivery pipe 16. A second oil delivery hole 35 is formed in the outer wall of the outer ring 3 at the position of the first oil replenishing pipe 10, and a first oil delivery hole 23 is formed in the outer wall of the outer ring 3 at the position of the second oil replenishing pipe 17. A first push plate 24 is fixed to the right side of the second rack 22, and a second push plate 25 is fixed to the left side of the first rack 21. The second rack 22 is slidably arranged in the inner wall of the second oil replenishing pipe 17, and the first rack 21 is slidably arranged in the inner wall of the first oil delivery pipe 11;

[0047] Specifically, when lubrication is required for two sets of tapered roller bearings, the operator can then move the second lever 19 and the first lever 13. When moving the second lever 19 and the first lever 13, the first rack 21 fixed to the bottoms of the second lever 19 and the first lever 13 will drive the second rack 22 to slide through the gear 36. Note that a first spring 12 is fixed to the front side of the first lever 13, and a second spring 18 is fixed to the rear side of the second lever 19. Their main function is that when the first lever 13 and the second lever 19 slide to the maximum distance, releasing the first lever 13 and the second lever 19 at this time will quickly return to their original positions under the resilience of the first spring 12 and the second spring 18, facilitating the operator to add lubricating oil multiple times;

[0048] Next, a first oil pipe 11 and a second oil pipe 16 are respectively fixed to the front and rear sides of the arc-shaped fixing block 14, and a first oil replenishing pipe 10 and a second oil replenishing pipe 17 are respectively fixed to their bottoms. First oil holes 23 and second oil holes 35 are provided in the outer wall of the outer ring 3 at the positions of the first oil replenishing pipe 10 and the second oil replenishing pipe 17. Their main function is to facilitate adding lubricating oil into the outer ring 3, and then infiltrating the two sets of tapered roller bearings to achieve the desired effect. A first oil tank 8 and a second oil tank 9 are respectively fixed to the inner walls on both sides of the arc-shaped fixing block 14. Their main function is to store lubricating oil, facilitating quickly releasing the lubricating oil into the outer ring 3 when needed;

[0049] It should be mentioned here that the first fuel tank 8 and the second fuel tank 9 are respectively connected to the first oil delivery pipe 11 and the second oil delivery pipe 16 through the second oil suction pipe 20 and the first oil suction pipe 15. The fixing position of the arc-shaped fixing block 14 is on the outer wall of the outer ring 3. Among them, the first fuel tank 8 and the second fuel tank 9 are fixed at both ends of the inner wall of the arc-shaped fixing block 14. Between the first fuel tank 8 and the second fuel tank 9 is a fuel supplement toggle rod. Then, it should be explained here that there is only space for the first push plate 24 and the second push plate 25 to move inside the first oil delivery pipe 11 and the second oil delivery pipe 16 to ensure the airtightness of the space, and they move driven by the first rack 21 and the second rack 22. It should be noted here that on the inner walls of the second oil suction pipe 20 and the first oil suction pipe 15, there is a one-way rotating baffle, which is connected internally by a torsion spring. The rotating direction of this baffle is the same as the oil outlet direction. Similarly, at both ends of the first oil delivery pipe 11 and the second oil delivery pipe 16, there are also two groups of rotating baffles, and the other ends are connected by torsion springs. The rotating directions of these two groups of baffles are the same as the oil outlet direction. Therefore, when the first rack 21 and the second rack 22 move, a suction and a push action will be generated. Therefore, this action can supplement oil to the tapered roller bearing assembly 2. When the second toggle rod 19 and the first toggle rod 13 are not stressed, the first rack 21 and the second rack 22 just fit with the second oil suction pipe 20 and the first oil suction pipe 15. At the same time, the baffles in the second oil suction pipe 20 and the first oil suction pipe 15 will prevent the oil in the first fuel tank 8 and the second fuel tank 9 from leaking. Similarly, the baffles in the first oil delivery pipe 11 and the second oil supplement pipe 17 will fit tightly with their inner walls under the action of the torsion springs, blocking the oil supplement to the tapered roller bearing assembly 2. At this time, the oil supplement to the tapered roller bearing assembly 2 ends. By repeating this process, rapid oil supplement to the inside of the tapered roller bearing assembly 2 can be achieved;

[0050] Finally, when the second toggle rod 19 and the first toggle rod 13 are toggled, the first push plate 24 and the second push plate 25 are respectively fixed on both sides. Note that the first push plate 24 and the second push plate 25 fit completely with the first oil delivery pipe 11 and the second oil delivery pipe 16 and will form a certain negative pressure space. That is, when the first toggle rod 13 and the second toggle rod 19 are toggled, at this time, the oil blocking plates of the second oil suction pipe 20 and the first oil suction pipe 15 will be opened, and the inner side panels of the oil discharge pipes, the first oil supplement pipe 10 and the second oil supplement pipe 17, will be closed due to the suction force. When the first toggle rod 13 and the second toggle rod 19 are released, at this time, due to the resilience of the first spring 12 and the second spring 18, the oil inlet panels in the second oil suction pipe 20 and the first oil suction pipe 15 will be closed, and the oil delivery panels in the first oil supplement pipe 10 and the second oil supplement pipe 17 will be opened. By repeating this process, quantitative and rapid oil supplement and lubrication can be achieved for the two groups of tapered roller bearings inside the outer ring 3, thereby reducing the friction force and absorbing a certain amount of heat.

[0051] A two-way thrust tapered roller bearing with a lining sleeve and a manufacturing method. Specifically, the material of the tapered roller bearing assembly 2 is high-carbon chromium steel, the materials of the base 26 and the shaft ring 27 are carburized and quenched steel, and the material of the outer ring 3 is copper alloy. The base 26 is forged and then machined into the required shape and size by turning. Next, the tapered rollers 28 are carburized and quenched to improve their hardness and wear resistance. The surfaces of the shaft ring 27 and the base 26 are precisely ground and polished to ensure their accuracy and surface finish. The tapered rollers 28 are installed in the pockets of the shaft ring 27, and then the base 26 is installed on the inner wall of the outer ring 3. A free clearance ring is installed on the inner wall of the outer ring 3. Finally, the inner ring cover is covered and fixed, and then assembled. The assembled bearing needs to be strictly inspected and tested to ensure that it meets the actual design requirements and usage standards.

[0052] Working principle of the present invention: When in use, first connect the rotating shaft 1 to the equipment, then assemble the two groups of tapered roller bearing assemblies 2 in the outer ring 3, and open four groups of through holes 7 at equal intervals on the outer wall of the outer ring 3. A first slider 30 is fixed to the outer wall of the inner ring of one group of tapered roller bearings, and the first slider 30 is slidably arranged on the inner wall of the through hole 7. At the same time, four groups of fixing blocks 34 are fixed at equal intervals on the outer wall of the outer ring 3 at the through hole 7, and their main purpose is to cooperate with the first slider 30. A third spring 33 is arranged inside the fixing block 34, and its main material The third spring 33 is made of steel. The left end of the third spring 33 is connected to the second slider 32. The second slider 32 is connected to the first slider 30 through the rotating shaft 1. When the stress on the tapered roller bearing reaches the maximum, the tapered roller bearing in the tapered roller bearing assembly 2 will apply pressure to the second free gap ring 29. Note that the pressure is the remaining stress of the tapered roller bearing after absorbing the maximum stress. When the second free gap ring 29 is subjected to the stress from the tapered roller bearing, it will slide to the right. At the same time, the four groups of pressure blocks 31 will gradually compress the third spring 33. Spring 33 is used until the free clearance ring reaches the ideal thickness, so as to reduce the impact force directly acting on the tapered roller bearing and the raceway, thereby extending the service life of the tapered roller bearing. At the same time, this design can ensure that the structure of the tapered roller bearing itself remains stable when the tapered roller bearing is subjected to the ultimate load, avoiding damage to the parts inside the bearing due to excessive stress, thereby affecting the normal operation of the equipment. When the two sets of tapered roller bearings need to be lubricated, the staff can toggle the second lever 19 and the first lever 13. When the second lever 19 and the first lever are toggled 13, the first rack 21 fixed on the second lever 19 and the bottom of the first lever 13 will drive the second rack 22 to slide through the gear 36. Note that the first spring 12 is fixed on the front side of the first lever 13, and the second spring 18 is fixed on the rear side of the second lever 19. The main function of the first spring 12 and the second lever 18 is that when the first lever 13 and the second lever 19 slide to the maximum distance, the first lever 13 and the second lever 19 are released, and the lever 19 will quickly recover under the rebound force of the first spring 12 and the second spring 18, so that the staff can add lubricating oil multiple times.
