Description

Technical Field

[0001] This application relates to the field of tapered roller bearing technology, and more specifically, to a combined tapered roller bearing. Background Technology

[0002] Tapered roller bearings are a common type of rolling bearing. They have tapered inner and outer raceways, and the rollers are frustum-shaped. This design allows tapered roller bearings to simultaneously withstand radial and axial loads and provides good self-aligning performance. The larger the contact angle of the bearing, the higher its axial load capacity.

[0003] In related technologies, combined tapered roller bearings are separable, meaning the inner ring assembly (comprised of an inner ring with rollers and a cage) can be installed separately from the outer ring. Firstly, during transport, the separate components of a combined tapered roller bearing are prone to loss. By assembling the combined bearing and ensuring the stability of each component, the risk of loss during transport can be reduced. Secondly, during installation, the inner ring is typically fitted onto the shaft with a tight fit, and the outer ring is fitted into the bearing housing with a tight fit. The conventional installation method for combined tapered roller bearings is manual hammering, which is labor-intensive, especially for large tapered roller bearings. Furthermore, tapered roller bearings are easily damaged or scratched by hammering. Therefore, the design of bearings that incorporate appropriate installation aids is a necessary consideration. Given these two situations, combining a single tool for both transport and installation assistance is also a problem that needs to be addressed. Summary of the Invention

Detailed Implementation

[0021] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The following description, with reference to the accompanying drawings, describes a combined tapered roller bearing according to an embodiment of this application.

[0024] Please see Figures 1 to 18The combined tapered roller bearing according to the embodiments of this application includes: a tapered roller bearing outer ring 100, a tapered roller inner ring assembly 200, an outer ring clamping and stabilizing assembly 300, an inner ring clamping and stabilizing assembly 400, a layered clamping and stabilizing assembly 500, a clamping screw assembly 600, a shaft 700, and a bearing housing 800.

[0025] Please see Figures 1 to 5The tapered roller inner ring assembly 200 includes two inner rings 210, two cages 220, and rollers 230. The two cages 220 are symmetrically arranged between the two inner rings 210 and the outer ring 100 of the tapered roller bearing. The rollers 230 are evenly spaced on the two cages 220. The rollers 230 roll along the outer wall of the inner ring 210 and the inner wall of the outer ring 100 of the tapered roller bearing. The outer ring clamping and stabilizing assembly 300 can be connected to the left side wall of the outer ring 100 of the tapered roller bearing. The inner ring clamping and stabilizing assembly 400 is clamped to the right side wall of the right inner ring 210. The inner ring clamping and stabilizing assembly 400 can press against the side of the bearing housing 800 near the shaft 700. The outer ring clamping and stabilizing assembly 300 can extend into the bearing housing 800 along with the outer ring 100 of the tapered roller bearing. The layered clamping and stabilizing assembly 500 is arranged on the right side wall and the left side wall of the outer ring 100 of the tapered roller bearing. Between the left side walls of the inner ring 210, the layered clamping stabilizing assembly 500 can be connected to the left side wall of the outer ring 100 of the tapered roller bearing. The clamping screw assembly 600 is configured as four sets, and the four sets of clamping screw assemblies 600 pass through the outer ring clamping stabilizing assembly 300, the inner ring clamping stabilizing assembly 400 and the layered clamping stabilizing assembly 500 in sequence. The four sets of clamping screw assemblies 600 are evenly distributed around the outer ring clamping stabilizing assembly 300, the inner ring clamping stabilizing assembly 400 and the layered clamping stabilizing assembly 500, and the clamping screw assembly 600 is clamped to the outer ring clamping stabilizing assembly 300 and the inner ring clamping stabilizing assembly 400. One end of the clamping screw assembly 600 can be connected to the end of the shaft 700. Both the outer ring clamping stabilizing assembly 300 and the layered clamping stabilizing assembly 500 can push the inner ring 210 to be fitted onto the outer wall of the end of the shaft 700 by a tight fit. During transportation, the outer ring clamping and stabilizing assembly 300 is connected to the left side wall of the outer ring 100 of the tapered roller bearing. Two cages 220 and rollers 230 are mounted on two aligned inner rings 210 to form the tapered roller inner ring assembly 200. The inner ring clamping and stabilizing assembly 400 and the layered clamping and stabilizing assembly 500 are used to position the tapered roller inner ring assembly 200. The clamping screw assembly 600 passes through the outer ring clamping and stabilizing assembly 300, the outer ring 100 of the tapered roller bearing, the layered clamping and stabilizing assembly 500, the two aligned inner rings 210, and the inner ring clamping and stabilizing assembly 400, and is then clamped by the clamping screw assembly 600. The outer ring clamping and stabilizing assembly 300 and the inner ring clamping and stabilizing assembly 400 are mutually clamped together, which stabilizes the outer ring 100 and the inner ring 200 of the tapered roller bearing. The cage 220 and the rollers 230 are stabilized on the inner ring 210. The outer ring 100, the two inner rings 210, the two cages 220 and the rollers 230 are mutually stabilized, reducing the possibility of loss of components during transportation.

[0026] During installation, the outer ring clamping and stabilizing assembly 300 is connected to the left side wall of the tapered roller bearing outer ring 100, with the left sides of the tapered roller bearing outer ring 100 and bearing housing 800 aligned. The inner ring clamping and stabilizing assembly 400 is pressed against the right side of the bearing housing 800. The clamping screw assembly 600 passes through the outer ring clamping and stabilizing assembly 300, the tapered roller bearing outer ring 100, the bearing housing 800, and the inner ring clamping and stabilizing assembly 400. The clamping screw assembly 600 then clamps the outer ring clamping and stabilizing assembly 300 and the inner ring clamping and stabilizing assembly 400. As the four clamping screw assemblies 600 are adjusted, the outer ring clamping and stabilizing assembly 300 drives the tapered roller bearing outer ring 100 to be pressed into the bearing housing 800. The four clamping screw assemblies 600 are simultaneously... To minimize the chance of the outer ring 100 of the tapered roller bearing getting stuck in the bearing housing 800, the tapered roller bearing outer ring 100 is slowly and synchronously inserted into the bearing housing 800 in four directions. The clamping screw assembly 600 is then removed, and one end of the clamping screw assembly 600 is connected to the end of the shaft 700. The assembled tapered roller inner ring assembly 200 is then installed inside the tapered roller bearing outer ring 100 mounted on the bearing housing 800. Finally, the tapered roller bearing outer ring 100, the assembled tapered roller inner ring assembly 200, and the bearing housing 800 are fitted onto the clamping screw assembly 600. The layered clamping stabilizing assembly 500 is then installed on the clamping screw assembly 600. The clamping screw assembly 600 is adjusted to ensure the layered clamping stabilizing assembly... The inner ring 210 is pressed onto the shaft 700 by component 500. The clamping screw assembly 600 is then adjusted, causing the outer ring 100 of the tapered roller bearing, the inner ring assembly 200, and the bearing housing 800 to move along the shaft 700 with the inner ring 210 and engage with it. Once the layered clamping stabilizing assembly 500 abuts against the end of the shaft 700, it is replaced with the outer ring clamping stabilizing assembly 300. The outer ring clamping stabilizing assembly 300 continues to clamp and drive the inner ring 210 to continue moving along the shaft until both inner rings 210 are fully installed on the shaft 700. This installation method requires less manual labor and reduces damage or abrasion to the outer ring 100 and inner ring assembly 200 caused by impact. This combined tapered roller bearing features a protective mechanism to prevent loss of components during transportation. Furthermore, during installation, it utilizes the outer ring clamping and stabilizing assembly 300, inner ring clamping and stabilizing assembly 400, layered clamping and stabilizing assembly 500, and clamping screw assembly 600—all components that were protected during transportation—for auxiliary installation. This improves the utilization rate of the transportation tool and allows for the completion of both auxiliary transportation and installation with a single set of tools. It should be noted that the outer ring clamping and stabilizing assembly 300, inner ring clamping and stabilizing assembly 400, layered clamping and stabilizing assembly 500, and clamping screw assembly 600 are recyclable and reusable.

[0027] Please see Figures 1 to 6The tapered roller bearing outer ring 100 includes an outer ring body 110. A threaded hole 120 is provided on the left side wall of the outer ring body 110. An outer ring clamping and stabilizing assembly 300 and a layered clamping and stabilizing assembly 500 can be detachably connected to the threaded hole 120 of the outer ring body 110. The outer ring clamping and stabilizing assembly 300 and the layered clamping and stabilizing assembly 500 are connected through the threaded hole 120 on the outer ring body 110. An oil groove 130 is provided on the outer wall of the outer ring body 110, and an oil hole 140 is provided on the oil groove 130, extending to the inner wall of the outer ring body 110. The oil groove 130 corresponds to the oil cup on the bearing housing 800, allowing lubricating oil to enter the inner wall of the outer ring body 110 through the oil groove 130 and the oil hole 140. This facilitates the lubricating oil to enter the roller 230 between the outer ring body 110 and the inner ring 210, thereby facilitating the lubrication of the roller 230, reducing friction, and minimizing damage to the roller 230.

[0028] Please see Figures 1 to 7 The outer ring clamping and stabilizing assembly 300 includes an outer ring clamping frame 310, an inner ring mounting ring 330, an outer ring mounting ring 340, and a connecting bolt 360. The outer ring mounting ring 340 and the inner ring mounting ring 330 are fixedly connected to the right side wall of the outer ring clamping frame 310. The outer ring clamping frame 310 has four first through holes 320 around its perimeter. The inner ring mounting ring 330 is located inside the outer ring mounting ring 340. The four first through holes 320 are located inside the inner ring mounting ring 330. The clamping screw assembly 600 can pass through the first through holes 320 and can clamp the outer ring clamping frame 310. The outer ring mounting ring 340 has a first mounting hole 350. The connecting bolt 360 can pass through the first mounting hole 350 and be connected to the threaded hole 120. The inner ring mounting ring 330 can clamp the right side wall of the inner ring 210. The connecting bolt 360 can pass through the layered clamping and stabilizing assembly 500 and be connected to the threaded hole 120. During transportation, the outer ring mounting ring 340 is connected to the threaded hole 120 of the outer ring body 110 via connecting bolts 360, maintaining the stability of the outer ring body 110. When the outer ring clamping stabilizing assembly 300 assists in the installation of the inner ring 210 and the shaft 700, the outer ring mounting ring 340 is reconnected to the threaded hole 120 of the outer ring body 110 via connecting bolts 360, and the inner ring mounting ring 330 clamps the inner ring 210, pressing the inner ring 210 onto the shaft 700, thus assisting in the installation of the inner ring 210 and the shaft 700. When assisting in the installation of the inner ring 210 and the shaft 700, the layered clamping stabilizing assembly 500 is connected to the threaded hole 120 of the outer ring body 110 via connecting bolts 360, maintaining the stability of the layered clamping stabilizing assembly 500 and facilitating the layered clamping stabilizing assembly 500 to push the inner ring 210 onto the shaft 700.

[0029] Please see Figures 1 to 8The layered clamping and stabilizing assembly 500 includes a second inner retaining ring 510, a second inner cross 520, a second connecting plate 540, and a second outer retaining bracket 550. The second inner cross 520 is fixedly connected to the inner wall of the second inner retaining ring 510. A third through hole 530 is provided around the second inner cross 520, through which the clamping screw assembly 600 can pass and clamp the left side wall of the second inner cross 520. The second connecting plate 540 is fixedly connected to the outer wall of the second inner retaining ring 510 at equal intervals. The inner wall of the second outer retaining bracket 550 is fixedly connected to the outer end of the second connecting plate 540. A second mounting hole 560 is provided on the second outer retaining bracket 550, which allows the connecting bolt 360 to pass through. After passing through the second mounting hole 560, the connecting bolt 360 can be connected to the threaded hole 120. The second inner cross 520 is used to strengthen the second inner retaining ring 510 and provides a fulcrum for adjusting the clamping screw assembly 600. During transportation, the second outer retaining bracket 550 clamps the outer ring body 110 away from the threaded hole 120, keeping the outer ring body 110 stable in conjunction with the outer ring mounting ring 340. The second inner retaining ring 510 clamps one of the inner rings 210 of the assembled tapered roller inner ring assembly 200, and in conjunction with the inner ring clamping stabilizing assembly 400 clamping the other inner ring 210, stabilizes the assembled tapered roller inner ring assembly 200, reducing the occurrence of component loss. Furthermore, the layered clamping stabilizing assembly 500 separates the tapered roller bearing outer ring 100 and the tapered roller inner ring assembly 200, reducing the impact between the tapered roller bearing outer ring 100 and the tapered roller inner ring assembly 200 during transportation, and reducing wear and damage to the rollers 230. When the layered clamping stabilizing assembly 500 is installed on the auxiliary inner ring 210 and the shaft 700, the second outer retainer 550 is connected to the threaded hole 120 of the outer ring body 110 by the connecting bolt 360, stabilizing the layered clamping stabilizing assembly 500. The clamping screw assembly 600 is adjusted, and the clamping screw assembly 600 drives the second inner cross 520. The second inner cross 520 drives the second inner retaining ring 510 to clamp the inner ring 210, so that the inner ring 210 is pressed into the shaft 700. The outer ring 100 of the tapered roller bearing and the bearing seat 800 move with the second outer retainer 550.

[0030] Please see Figures 1 to 10 In related technologies, during transportation, the outer ring body 110 is stabilized by the connecting bolts 360 on the outer ring mounting ring 340 in conjunction with the second outer retainer 550. However, due to the bumps during transportation, the connecting bolts 360 are easily subjected to shearing forces by the impact force of the outer ring body 110. Therefore, how to reduce the shearing force on the connecting bolts 360 caused by the bumps during transportation and reduce the connection failure between the outer ring mounting ring 340 and the outer ring body 110 has become a technical problem that needs to be solved.

[0031] Specifically, the second outer retaining ring 550 includes a second outer retaining ring 551, a positioning sleeve 552, and a rubber sleeve 553. The positioning sleeve 552 is fixedly connected to the left side wall of the second outer retaining ring 551. The rubber sleeve 553 wraps around the outer wall of the positioning sleeve 552 and can be inserted into and fit against the inner wall of the inner ring 210. One side of the outer ring body 110 is connected by an outer ring mounting ring 340 and a connecting bolt 360. The positioning sleeve 552 of the second outer retaining ring 551 is inserted into the other side of the outer ring body 110, forming stability on the other side of the outer ring body 110, reducing the shear force generated by the impact of transportation bumps on the outer ring body 110 on the connecting bolt 360, and reducing the possibility of connection failure between the outer ring mounting ring 340 and the outer ring body 110 connecting bolt 360. The positioning sleeve 552 and the inner wall of the outer ring body 110 are protected by a rubber sleeve 553 to reduce wear between the positioning sleeve 552 and the inner wall of the outer ring body 110 during transportation.

[0032] Please see Figures 1 to 11 The inner ring clamping and stabilizing assembly 400 includes a first inner retaining ring 410, a first inner cross 420, a first connecting plate 440, a first outer retaining ring 450, and an outer stop block 460. The first inner cross 420 is fixedly connected to the inner wall of the first inner retaining ring 410. The first connecting plate 440 is evenly spaced on the outer wall of the first inner retaining ring 410. The inner wall of the first outer retaining ring 450 is fixedly connected to the outer end of the first connecting plate 440. The outer stop block 460 is evenly spaced on the outer wall of the first outer retaining ring 450. The left side walls of the first outer retaining ring 450 and the outer stop block 460 can clamp the right side wall of the bearing seat 800. The first inner cross 420 has a second through hole 430 around its perimeter. The clamping screw assembly 600 can pass through the second through hole 430 and can clamp the first inner cross 420. During transportation, the first inner retaining ring 410 presses against the inner ring 210 of the assembled tapered roller inner ring assembly 200. The first inner retaining ring 410, in conjunction with the second inner retaining ring 510, presses against the assembled tapered roller inner ring assembly 200. The first outer retaining ring 450, in conjunction with the outer ring mounting ring 340, secures the outer ring body 110, stabilizing it. When the inner ring clamping and stabilizing assembly 400 assists in the installation of the outer ring body 110 and the bearing housing 800, the first outer retaining ring 450 presses against the right side wall of the bearing housing 800. The first inner cross 420 provides another fulcrum for the clamping screw assembly 600, enabling the clamping screw assembly 600 to clamp and drive the outer ring mounting ring 340. The outer stop block 460 increases the contact area between the first outer retaining ring 450 and the right side wall of the bearing housing 800.

[0033] Please see Figures 1 to 11In related technologies, when the assembled tapered roller inner ring assembly 200 is transported, it is pressed and stabilized by the second inner retaining ring 510 in conjunction with the first inner retaining ring 410. However, the assembled tapered roller inner ring assembly 200 is also easily affected by the bumps during transportation, causing displacement and unilateral offset. This can easily cause the inner ring 210 to press against the clamping screw assembly 600, and cause the assembled tapered roller inner ring assembly 200 to protrude from the second inner retaining ring 510 and the first inner retaining ring 410. How to reduce the unilateral offset of the assembled tapered roller inner ring assembly 200 caused by the bumps has become a technical problem that needs to be solved.

[0034] In specific implementation, the first positioning cylinder 470 is fixedly connected to the left side wall of the first inner retaining ring 410, and the second positioning cylinder 580 is fixedly connected to the right side wall of the second inner retaining ring 510. The first positioning cylinder 470 is sleeved on the end of the second positioning cylinder 580. After the first positioning cylinder 470 and the second positioning cylinder 580 are connected, the length is equal to the thickness of the two inner rings 210. During transportation, the first positioning cylinder 470 of the first inner retaining ring 410 and the second positioning cylinder 580 of the second inner retaining ring 510 are both inserted into the inner ring 210 of the assembled tapered roller inner ring assembly 200. The positions of the two inner rings 210 are defined by the first inner retaining ring 410 and the second inner retaining ring 510, reducing the movement of the two inner rings 210 on the first positioning cylinder 470 and the second positioning cylinder 580. The positions of the assembled tapered roller inner ring assembly 200 are defined by the first positioning cylinder 470 and the second positioning cylinder 580, reducing the occurrence of unilateral displacement of the assembled tapered roller inner ring assembly 200 due to bumps.

[0035] Please see Figures 1 to 13The first positioning shaft cylinder 470 includes a first cylinder body 471 and a first wrapping rubber cylinder 472. The first wrapping rubber cylinder 472 is fixedly wrapped around the outer wall of the first cylinder body 471. The first cylinder body 471 is located at one end away from the first inner retaining ring 410. The second positioning shaft cylinder 580 includes a second cylinder body 581, a snap-fit ​​cylinder body 582, and a second wrapping rubber cylinder 583. The snap-fit ​​cylinder body 582 is fixedly connected to the second cylinder body 581 at one end away from the second inner retaining ring 510. One end of the snap-fit ​​cylinder body 582 extends out of the second cylinder body 581. The second wrapping rubber cylinder 583 is fixedly wrapped around the outer wall of the second cylinder body 581. The first cylinder body 471 is sleeved on the outer wall of the snap-fit ​​cylinder body 582. The outer diameter of the first wrapping rubber cylinder 472 is the same as the outer diameter of the second wrapping rubber cylinder 583. The outer walls of the first wrapping rubber cylinder 472 and the second wrapping rubber cylinder 583 are attached to the inner walls of the two inner rings 210. The positions of the first cylinder 471 and the second cylinder 581 are defined by the snap-fit ​​cylinder 582, so that the first cylinder 471 and the second cylinder 581 are connected to each other. The outer diameter of the first wrapping rubber cylinder 472 and the second wrapping rubber cylinder 583 respectively wrap the first cylinder 471 and the second cylinder 581, reducing the contact between the first cylinder 471 and the second cylinder 581 and the inner wall of the two inner rings 210, thereby reducing the occurrence of damage to the inner wall of the inner ring 210 caused by the first cylinder 471 and the second cylinder 581.

[0036] Please see Figures 1 to 14The clamping screw assembly 600 is configured in four groups. The clamping screw assembly 600 includes a screw 610, a first clamping nut 620 and a second clamping nut 630. The screw 610 passes through the outer ring clamping stabilizing assembly 300, the inner ring clamping stabilizing assembly 400 and the layered clamping stabilizing assembly 500 in sequence. The first clamping nut 620 and the second clamping nut 630 are threadedly connected to both ends of the screw 610. The first clamping nut 620 is clamped to the outer ring clamping stabilizing assembly 300 and the second clamping nut 630 is clamped to the inner ring clamping stabilizing assembly 400. During transportation, the screw 610 passes through the first through hole 320 on the outer ring clamping frame 310, the third through hole 530 on the second inner cross 520, and the second through hole 430 on the first inner cross 420. The first clamping nut 620 and the second clamping nut 630 are screwed into the two ends of the screw 610 respectively. The first clamping nut 620 clamps the outer ring clamping frame 310, and the second clamping nut 630 clamps the first inner cross 420. Through the mutual clamping action of the first clamping nut 620 and the second clamping nut 630 on the screw 610, the outer ring of the tapered roller bearing 100, the outer ring clamping and stabilizing assembly 300, the layered clamping and stabilizing assembly 500, the assembled tapered roller inner ring assembly 200, and the inner ring clamping and stabilizing assembly 400 are mutually clamped to form a stable whole, reducing the occurrence of loose or lost parts during transportation. When installing the outer ring body 110 and the bearing housing 800, the outer ring mounting ring 340 is connected to the outer ring body 110. The screw 610 passes through the first through hole 320 on the outer ring clamping frame 310, the outer ring body 110, the bearing housing 800, and the second through hole 430 on the first inner cross 420. The first clamping nut 620 clamps the outer ring clamping frame 310, and the second clamping nut 630 clamps the first inner cross 420. As the first clamping nut 620 and the second clamping nut 630 are continuously screwed into the screw 610, the outer ring clamping frame 310 drives the outer ring body 110 to gradually press into the interior of the bearing housing 800 until the installation of the outer ring body 110 and the bearing housing 800 is completed. This reduces the consumption of manpower and also reduces the occurrence of damage to the outer ring body 110 caused by impact installation.During the installation of the inner ring 210 and the shaft 700, one end of the screw 610 is screwed into the end of the shaft 700 (it should be noted that if installing on an existing shaft 700, a connection hole can be pre-drilled at the end of the shaft 700. Since the connection hole is located at the end of the shaft 700, and the inner ring 210 will extend beyond the end of the shaft 700 after installation, the impact on the strength of the connection between the inner ring 210 and the shaft 700 is minimal). The layered clamping and stabilizing assembly 500 is connected to the outer ring body 110. The other end of the screw 610 passes through the assembled tapered roller inner ring assembly 200 pre-installed in the outer ring body 110, and then passes through the third through hole 530 on the second inner cross 520. The first inner cross 420 is clamped by the first clamping nut 620. As the first clamping nut 620 is screwed into the screw 610, the second inner retaining ring 510 is clamped and drives the inner ring 210 to gradually press into the shaft 700. When the shaft 700... After the end blocks the layered clamping and stabilizing assembly 500, remove the first clamping nut 620, disconnect the layered clamping and stabilizing assembly 500 from the outer ring body 110, pull out the layered clamping and stabilizing assembly 500, replace the layered clamping and stabilizing assembly 500 with the outer ring clamping and stabilizing assembly 300, connect the outer ring clamping and stabilizing assembly 300 to the outer ring body 110, and screw the first clamping nut 620 back on. Through the clamping of the first clamping nut 620, the inner ring mounting ring 330 continues to clamp and drives the two inner rings 210 to be fully pressed into the shaft 700. The outer ring body 110, bearing housing 800, cage 220 and roller 230 move with the two inner rings 210. Then, remove the screw 610 and disconnect the outer ring clamping and stabilizing assembly 300 from the outer ring body 110 to complete the installation of the entire bearing, reducing manpower consumption and reducing the occurrence of damage to the inner ring 210 caused by impact installation.

[0037] Please see Figures 1 to 16 In related technologies, when installing the inner ring 210 and shaft 700 of a tapered roller bearing, the inner ring 210 is first assisted by the layered clamping stabilizing assembly 500 in conjunction with the clamping screw assembly 600, and then the inner ring 210 is assisted by the outer ring clamping stabilizing assembly 300 in conjunction with the clamping screw assembly 600. However, during the installation of the inner ring 210 assisted by the outer ring clamping stabilizing assembly 300, the size of the bearing clearance directly affects the bearing's load capacity, stiffness, temperature rise, and lifespan. Therefore, it is necessary to control the clearance between the inner ring 210, the outer ring body 110, and the rollers 230 to reduce the occurrence of excessive pressure from the inner ring 210 on the rollers 230 or excessive clearance between the rollers 230 and the inner ring 210. Therefore, how to control the clearance between the inner ring 210, the outer ring body 110, and the rollers 230 during the installation of the inner ring 210 assisted by the outer ring clamping stabilizing assembly 300 has become a technical problem that needs to be solved.

[0038] It should be noted that the right side walls of the outer ring mounting ring 340 and the inner ring mounting ring 330 are located on the same plane. The right side wall of the outer ring mounting ring 340 is fixedly connected to the first limiting ring 380. The thickness of the first limiting ring 380 is equal to the distance from the left side wall of the outer ring 100 of the tapered roller bearing to the left side wall of the left inner ring 210. The first mounting hole 350 passes through the outer ring mounting ring 340 and the first limiting ring 380. The first limiting ring 380 can be fixed to the outer ring 100 of the tapered roller bearing by the connecting bolt 360. The outer ring mounting ring 340 can press against the left side wall of the left inner ring 210. When the outer ring clamping and stabilizing assembly 300, in conjunction with the clamping screw assembly 600, assists in the installation of the inner ring 210, the connecting bolt 360 passes through the first mounting hole 350 and connects to the threaded hole 120 of the outer ring body 110, connecting the outer ring mounting ring 340 and the outer ring body 110 together. The first limiting ring 380 is pressed between the outer ring body 110 and the outer ring mounting ring 340. When the inner ring mounting ring 330 presses against the left side wall of the left inner ring 210, and the inner ring mounting ring 330 pushes the inner ring 210 into the shaft 700, the outer ring body 110 is driven by the outer ring mounting ring 340 to move synchronously, while the two inner rings 210 move in tandem. Since they do not interact directly, there is no direct force between the outer ring body 110 and the inner ring 210. The distance between the left side wall of the left inner ring 210 and the left side wall of the outer ring body 110 is controlled by the thickness of the first limiting ring 380. Because the distance between the left side wall of the left inner ring 210 and the left side wall of the outer ring body 110 remains unchanged, the gap between the inner ring 210, the outer ring body 110, and the roller 230 will not change with the installation of the inner ring 210. Therefore, the purpose of controlling the gap between the inner ring 210, the outer ring body 110, and the roller 230 is achieved during the installation process of the outer ring pressing and stabilizing component 300 assisted by the inner ring 210. A positioning retaining ring 480 is fixedly connected to the left side wall of the first outer retaining ring 450, and the positioning retaining ring 480 is inserted into the interior of the left side wall of the bearing seat 800. The positioning retaining ring 480 stabilizes the position of the first outer retaining ring 450 on the left side wall of the bearing housing 800, thereby reducing the occurrence of movement of the first outer retaining ring 450 on the left side wall of the bearing housing 800.

[0039] Please see Figures 1 to 17 The outer ring clamping bracket 310 includes an outer cross-shaped body 311 and raising pads 312. The raising pads 312 are fixedly connected at equal intervals to the periphery of the right side wall of the outer cross-shaped body 311. The outer ring mounting ring 340 and the inner ring mounting ring 330 are fixedly connected to the right side wall of the raising pads 312. The end of the shaft 700 can pass through the inner ring mounting ring 330 and extend into the space between the raising pads 312. When the outer ring clamping stabilizing assembly 300 cooperates with the clamping screw assembly 600 to assist in the installation of the inner ring 210, after the inner ring 210 is fully installed on the shaft 700, the end of the shaft 700 passes through the inner ring mounting ring 330 and extends into the space between the raising pads 312. The raising pads 312 reduce the interference between the outer cross-shaped body 311 and the shaft 700 during installation, thus reducing the possibility of the inner ring 210 not being installed properly.

[0040] Please see Figures 1 to 18 In related technologies, when installing the inner ring 210 of a tapered roller bearing and the shaft 700, the inner ring 210 is first assisted in the installation by using a layered clamping and stabilizing assembly 500 in conjunction with a clamping screw assembly 600. During the installation process assisted by the layered clamping and stabilizing assembly 500, it is also necessary to control the clearance between the inner ring 210, the outer ring body 110, and the rollers 230 to reduce the occurrence of excessive pressure from the inner ring 210 on the rollers 230 or excessive clearance between the rollers 230 and the inner ring 210. Therefore, how to control the clearance between the inner ring 210, the outer ring body 110, and the rollers 230 during the installation process assisted by the layered clamping and stabilizing assembly 500 becomes a technical problem that needs to be solved.

[0041] Specifically, a second limiting ring 570 is fixedly connected to the right side wall of the second outer retainer 550. The second inner retainer 510 and the right side wall of the second outer retainer 550 are located on the same plane. The thickness of the second limiting ring 570 is equal to the distance from the left side wall of the outer ring 100 of the tapered roller bearing to the left side wall of the left inner ring 210. The second mounting hole 560 passes through the second outer retainer 550 and the second limiting ring 570. The second limiting ring 570 can be fixed to the outer ring 100 of the tapered roller bearing by connecting bolts 360. The second inner retainer 510 can press against the left side wall of the left inner ring 210. When the layered clamping stabilizing assembly 500, in conjunction with the clamping screw assembly 600, assists in the installation of the inner ring 210, the connecting bolt 360 passes through the second mounting hole 560 and connects to the threaded hole 120 of the outer ring body 110, connecting the second outer retainer 550 and the outer ring body 110 together. The second limiting ring 570 is pressed between the outer ring body 110 and the second outer retainer 550. When the second inner retainer 510 presses against the left side wall of the left inner ring 210, the second inner retainer 510 pushes the inner ring 210 into the shaft 700. The outer ring body 110 is driven to move synchronously by the second outer retainer 550, while the two inner rings 210 are... Since they do not interact, there is no direct force between the outer ring body 110 and the inner ring 210. The distance between the left side wall of the left inner ring 210 and the left side wall of the outer ring body 110 is controlled by the thickness of the second limiting ring 570. Since the distance between the left side wall of the left inner ring 210 and the left side wall of the outer ring body 110 does not change, the gap between the inner ring 210, the outer ring body 110 and the roller 230 will not change with the installation of the inner ring 210. Therefore, the purpose of controlling the gap between the inner ring 210, the outer ring body 110 and the roller 230 is achieved during the installation of the inner ring 210 assisted by the layered pressing and stabilizing component 500.

[0042] See Figures 1 to 18The length of the second positioning cylinder 580 is less than the thickness of one and a half inner rings 210, and both inner rings 210 can be fitted onto the second positioning cylinder 580, with the outer wall of the second positioning cylinder 580 fitting against the inner wall of the inner rings 210. When the layered clamping and stabilizing assembly 500, together with the clamping screw assembly 600, assists in the installation of the inner rings 210, both inner rings 210 are fitted onto the second positioning cylinder 580, and the length of the second positioning cylinder 580 is less than the thickness of one and a half inner rings 210. The second positioning cylinder 580 can simultaneously position both inner rings 210. When the end of the second positioning cylinder 580 abuts against the end of the shaft 700, the inner ring 210 on the right side is supported and stabilized by the shaft 700.

[0043] Please see Figures 1 to 18 A positioning cylinder 370 is fixedly connected to the right side wall of the inner ring mounting ring 330. The outer wall of the inner ring 210 can be inserted into the positioning cylinder 370, and the outer wall of the inner ring 210 fits against the inner wall of the positioning cylinder 370. When the layered pressing and stabilizing component 500 is replaced with the outer ring pressing and stabilizing component 300 to assist in the installation of the inner ring 210, the inner ring 210 on the right side is supported and stabilized by the shaft 700, and the inner ring 210 on the left side is inserted into the positioning cylinder 370 for positioning. As the pressing screw assembly 600 is tightened, the inner ring mounting ring 330 drives the inner ring 210 on the right side to continue pressing into the shaft 700. After the inner ring 210 on the right side is fully pressed into the shaft 700, the inner ring 210 on the left side is fixed into the shaft 700 by the positioning cylinder 370, reducing the consumption of manual assistance in positioning the inner ring 210.

[0044] Specifically, the working principle of this combined tapered roller bearing is as follows: During transportation, the outer ring mounting ring 340 is connected to the threaded hole 120 of the outer ring body 110 via connecting bolts 360, maintaining the stability of the outer ring body 110. The second outer retainer 550 presses against the side of the outer ring body 110 away from the threaded hole 120, maintaining the stability of the outer ring body 110. This, combined with the fixation of the outer ring mounting ring 340, achieves the purpose of stabilizing the outer ring body 110. After the second inner retainer ring 510 is pressed and assembled... One of the inner rings 210 of the tapered roller inner ring assembly 200 is pressed by a first inner retaining ring 410 after assembly. The first inner retaining ring 410, together with a second inner retaining ring 510, presses the assembled tapered roller inner ring assembly 200. A first outer retaining ring 450, together with an outer ring mounting ring 340, secures the outer ring body 110, stabilizing the outer ring body 110. A screw 610 passes through the first through hole 32 on the outer ring clamping bracket 310. 0. The third through hole 530 on the second inner cross 520 and the second through hole 430 on the first inner cross 420, the first clamping nut 620 and the second clamping nut 630 are respectively screwed into the two ends of the screw 610 by threads. The first clamping nut 620 clamps the outer ring clamping frame 310, and the second clamping nut 630 clamps the first inner cross 420. Under the mutual clamping action of the first clamping nut 620 and the second clamping nut 630 on the screw 610, the outer ring mounting ring 340, the outer ring body 110 and the second outer retainer 550 are pressed together. The first inner retainer ring 410 cooperates with the second inner retainer ring 510 to press the assembled tapered roller inner ring assembly 200. The outer ring clamping stabilizing assembly 300, the layered clamping stabilizing assembly 500, the assembled tapered roller inner ring assembly 200 and the inner ring clamping stabilizing assembly 400 are pressed together to form a stable whole, reducing the occurrence of loose or lost parts during transportation. The first positioning cylinder 470 of the first inner retaining ring 410 and the second positioning cylinder 580 of the second inner retaining ring 510 are both inserted into the inner ring 210 of the assembled tapered roller inner ring assembly 200. The positions of the two inner rings 210 are defined by the first inner retaining ring 410 and the second inner retaining ring 510, reducing the movement of the two inner rings 210 on the first positioning cylinder 470 and the second positioning cylinder 580. The positions of the assembled tapered roller inner ring assembly 200 are defined by the first positioning cylinder 470 and the second positioning cylinder 580, reducing the occurrence of unilateral displacement of the assembled tapered roller inner ring assembly 200 due to bumps. The positions of the first cylinder 471 and the second cylinder 581 are defined by the snap-fit ​​cylinder 582, so that the first cylinder 471 and the second cylinder 581 are connected to each other. The outer diameter of the first wrapping rubber cylinder 472 and the second wrapping rubber cylinder 583 respectively wrap the first cylinder 471 and the second cylinder 581, reducing the contact between the first cylinder 471 and the second cylinder 581 and the inner wall of the two inner rings 210, thereby reducing the occurrence of damage to the inner wall of the inner ring 210 caused by the first cylinder 471 and the second cylinder 581.

[0045] When the outer ring body 110 is installed with the bearing housing 800, the outer ring mounting ring 340 is reconnected to the threaded hole 120 of the outer ring body 110 by the connecting bolt 360. The screw 610 passes through the first through hole 320 on the outer ring clamping frame 310, the outer ring body 110, the bearing housing 800, and the second through hole 430 on the first inner cross 420. The first clamping nut 620 clamps the outer ring clamping frame 310, the second clamping nut 630 clamps the first inner cross 420, and the first outer retaining ring 450 is clamped against the right side wall of the bearing housing 800. As the first clamping nut 620 and the second clamping nut 630 are continuously screwed into the screw 610, the outer ring clamping frame 310 drives the outer ring body 110 to gradually press into the interior of the bearing housing 800 until the installation of the outer ring body 110 and the bearing housing 800 is completed, reducing the consumption of manpower and reducing the occurrence of damage to the outer ring body 110 caused by impact installation.

[0046] During the installation of the inner ring 210 and the shaft 700, one end of the screw 610 is screwed into the end of the shaft 700. The connecting bolt 360 passes through the second mounting hole 560 and is then connected to the threaded hole 120 of the outer ring body 110, connecting the second outer retainer 550 and the outer ring body 110 together. The second limiting ring 570 is pressed between the outer ring body 110 and the second outer retainer 550. The other end of the screw 610 passes through the assembled tapered roller inner ring assembly 200 pre-installed in the outer ring body 110. Both inner rings 210 are fitted onto the second positioning shaft sleeve 580, and then pass through the third through hole 530 on the second inner cross 520. The first inner cross 420 is pressed by the first clamping nut 620. As the first clamping nut 620 is screwed into the screw 610, the second... The inner retaining ring 510 pushes the inner ring 210 into the shaft 700. The outer ring body 110 is driven to move synchronously by the second outer retaining bracket 550. Since the two inner rings 210 abut against each other, there is no direct force between the outer ring body 110 and the inner ring 210. The distance between the left side wall of the left inner ring 210 and the left side wall of the outer ring body 110 is controlled by the thickness of the second limiting ring 570. Because the distance between the left side wall of the left inner ring 210 and the left side wall of the outer ring body 110 remains unchanged, the gap between the inner ring 210, the outer ring body 110, and the roller 230 will not change with the installation of the inner ring 210. Therefore, during the installation process assisted by the layered pressing stabilizing component 500, the gap between the inner ring 210, the outer ring body 110, and the roller 230 is controlled. The purpose of the gap between the 30 and the outer ring is that when the end of the shaft 700 blocks the second positioning shaft cylinder 580, the layered clamping and stabilizing assembly 500 is replaced by the outer ring clamping and stabilizing assembly 300 to assist the installation of the inner ring 210. The connecting bolt 360 passes through the first mounting hole 350 and is connected to the threaded hole 120 of the outer ring body 110, connecting the outer ring mounting ring 340 and the outer ring body 110 together. The first limiting ring 380 is pressed between the outer ring body 110 and the outer ring mounting ring 340. The inner ring 210 on the right side is supported and stabilized by the shaft 700, and the inner ring 210 on the left side is inserted into the positioning cylinder 370 for positioning, reducing the consumption of manual assistance in positioning the inner ring 210. The inner ring mounting ring 330 presses against the left side wall of the left inner ring 210, and the inner ring mounting ring 330 pushes the inner ring. The outer ring 210 is pressed onto the shaft 700. The outer ring body 110 is driven to move synchronously by the outer ring mounting ring 340, while the two inner rings 210 abut against each other. Therefore, there is no direct force between the outer ring body 110 and the inner ring 210. The distance between the left side wall of the left inner ring 210 and the left side wall of the outer ring body 110 is controlled by the thickness of the first limiting ring 380. Since the distance between the left side wall of the left inner ring 210 and the left side wall of the outer ring body 110 does not change, the gap between the inner ring 210, the outer ring body 110, and the roller 230 will not change with the installation of the inner ring 210. Therefore, the purpose of controlling the gap between the inner ring 210, the outer ring body 110, and the roller 230 is achieved during the installation process of the inner ring 210 assisted by the outer ring pressing and stabilizing component 300.After the inner ring 210 is fully installed on the shaft 700, the end of the shaft 700 passes through the inner ring mounting ring 330 and extends into the space between the riser pads 312. The riser pads 312 reduce interference between the outer cross-shaped body 311 and the shaft 700 during installation, preventing the inner ring 210 from being improperly installed. Then, the screw 610 is removed, and the connection between the outer ring clamping and stabilizing assembly 300 and the outer ring body 110 is disconnected, completing the entire bearing installation. This reduces manpower consumption and the possibility of damage to the inner ring 210 due to impact during installation.
