Description

Technical Field

[0001] The utility model relates to the technical field of tapered roller bearings, in particular to a tapered roller bearing assembly which is convenient to disassemble. Background Technique

[0002] Tapered roller bearings belong to separable bearings, and both the inner and outer rings of the bearings have tapered raceways. Such bearings are divided into different structural forms such as single-row, double-row, and four-row tapered roller bearings according to the number of rows of the installed rollers.

[0003] Since the thicknesses on both sides of the outer ring of the bearing are different, there is no support point for the disassembly tool when the outer ring of the bearing is disassembled, and the disassembly tool is likely to slip when contacting the outer ring of the bearing. The slipping is likely to cause damage to the inner wall of the outer ring of the bearing and cannot be used again, thus increasing the maintenance cost. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a tapered roller bearing assembly which is convenient to disassemble, has the advantages of convenient and practical disassembly of the outer ring of the bearing, and solves the problems raised in the above background technique.

[0005] The utility model provides the following technical scheme: a tapered roller bearing assembly which is convenient to disassemble, includes a shaft body, an inner ring is installed on the outer edge of the shaft body, an outer ring is arranged on the outer wall of the inner ring, tapered rollers are rotatably connected between the outer ring and the inner ring, a positioning ring is arranged on the outer edge of the tapered rollers, a fixing steel ring is sleeved on the outer wall of the outer ring, a chute is opened on the outer wall of the fixing steel ring, a support block is slidably connected to the inner wall of the chute, and a sleeve is arranged on the outer wall of the fixing steel ring.

[0006] As a preferred technical scheme of the utility model, a threaded hole is fixedly opened on the outer edge of the fixing steel ring, and a threaded rod is threadedly connected to the inner wall of the threaded hole.

[0007] As a preferred technical scheme of the utility model, a hexagonal hole is opened at one end of the threaded rod, and a contact round block is fixedly assembled at the other end of the threaded rod.

[0008] As a preferred technical scheme of the utility model, a vertical long groove is opened on the outer edge of the support block, and the outer edge of the contact round block is slidably connected to the inner wall of the vertical long groove.

[0009] As a preferred technical scheme of the utility model, an anti-slip ring is closely attached to the inner wall of the vertical long groove, and a rubber gasket is fixedly equipped on the outer wall of the support block.

[0010] As a preferred technical scheme of the utility model, there are four chutes, support blocks, threaded rods and rubber gaskets respectively, and the four chutes, support blocks, threaded rods and rubber gaskets are evenly distributed on the fixing steel ring.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. For the easily detachable tapered roller bearing assembly, by rotating the threaded rod counterclockwise, the threaded rod rotates to pull the support block, and the support block is gradually driven into the chute. The rubber gasket is separated from the sleeve. At this time, the fixing steel ring can be taken out, and taking out the fixing steel ring will bring out the outer ring, thus solving the problem that the thicknesses on both sides of the outer ring of the bearing are different, there is no support point for the disassembly tool when disassembling the outer ring of the bearing, the disassembly tool is likely to slip when contacting the outer ring of the bearing, and the slipping is likely to cause damage to the inner wall of the outer ring of the bearing, resulting in an increase in maintenance costs.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1 - Figure 5 , a tapered roller bearing assembly that is easy to disassemble, including a shaft body 1. An inner ring 2 is installed on the outer edge of the shaft body 1. An outer ring 3 is provided on the outer wall of the inner ring 2. Tapered rollers 4 are rotatably connected between the outer ring 3 and the inner ring 2. A positioning ring 5 is provided on the outer edge of the tapered rollers 4. A fixed steel ring 7 is sleeved on the outer wall of the outer ring 3. A chute 8 is opened on the outer wall of the fixed steel ring 7. A support block 10 is slidably connected to the inner wall of the chute 8. A sleeve 6 is provided on the outer wall of the fixed steel ring 7. Through the setting of the support block 10, the support block 10 can slide in the chute 8. During disassembly, the support block 10 can be retracted into the chute 8, so that the support block 10 and the fixed steel ring 7 form a circle. At this time, the support block 10 does not protrude from the fixed steel ring 7. At this time, the fixed steel ring 7 and the outer ring 3 can be removed from the sleeve 6, making it more convenient to remove the outer ring 3. During installation, the support block 10 slides in the chute 8, so that the support block 10 contacts the inner wall of the sleeve 6. At this time, the support block 10 protrudes from the fixed steel ring 7, positioning the outer ring 3 in the inner cavity of the fixed steel ring 7 and facilitating the installation and fixation of the outer ring 3.

[0022] In a preferred embodiment, a threaded hole 9 is fixedly opened on the outer edge of the fixed steel ring 7. A threaded rod 15 is threadedly connected to the inner wall of the threaded hole 9. By rotating the threaded rod 15, the threaded rod 15 can push the support block 10 to move, so that the support block 10 slides in the chute 8 and contacts the inner wall of the sleeve 6. Reversing the threaded rod 15 can drive the support block 10 to retract, and the support block 10 does not contact the sleeve 6.

[0023] In a preferred embodiment, a hexagonal hole 16 is opened at one end of the threaded rod 15. The hexagonal hole 16 facilitates the use of tools. By inserting a hexagonal long rod into the hexagonal hole 16 and rotating it to drive the threaded rod 15 to rotate, the threaded rod 15 can be rotated. A contact round block 14 is fixedly assembled at the other end of the threaded rod 15. The cooperation between the contact round block 14 and the anti - detachment ring 13 plays a pulling role. When the threaded rod 15 rotates in the reverse direction, the threaded rod 15 drives the contact round block 14 to rotate. Gradually, the contact round block 14 pulls the anti - detachment ring 13 and the support block 10 to slide, so that the support block 10 retracts, improving the rationality of the device.

[0024] In a preferred embodiment, a vertical long groove 12 is provided on the outer edge of the support block 10. Due to the arrangement of the vertical long groove 12, when the threaded rod 15 rotates, the length of the threaded rod 15 located in the chute 8 will become longer. At this time, the threaded rod 15 will cause the support block 10 to move. Since the shape of the chute 8 is inclined, the support block 10 will move upward, and the threaded rod 15 above the vertical long groove 12 will become below the vertical long groove 12, improving the rationality of the device. The outer edge of the contact round block 14 is slidably connected to the inner wall of the vertical long groove 12, and the contact round block 14 slides in the vertical long groove 12, enabling the support block 10 to slide. The protruding fixed steel ring 7 of the support block 10 contacts the sleeve 6.

[0025] In a preferred embodiment, an anti - detachment ring 13 is closely attached to the inner wall of the vertical long groove 12, and a rubber gasket 11 is fixedly equipped on the outer wall of the support block 10. Due to the elastic property of the rubber gasket 11, when the threaded rod 15 supports the support block 10, the elasticity of the rubber gasket 11 provides reverse support for the support block 10 and the threaded rod 15, making the threads on the threaded rod 15 fit more tightly with the threads in the threaded hole 9 and improving the stability of the device.

[0026] In a preferred embodiment, there are four chutes 8, support blocks 10, threaded rods 15, and rubber gaskets 11 respectively, and the four chutes 8, support blocks 10, threaded rods 15, and rubber gaskets 11 are evenly distributed on the fixed steel ring 7. Due to the arrangement of the four chutes 8, support blocks 10, threaded rods 15, and rubber gaskets 11, by tightening the threaded rods 15 in sequence, the four support blocks 10 and rubber gaskets 11 contact the sleeve 6 more stably, making the outer ring 3 receive more uniform force.

[0027] Working principle: When in use, the inner ring 2, tapered rollers 4, and positioning ring 5 are installed on the shaft body 1. Then the outer ring 3 is installed in the fixed steel ring 7, and then the fixed steel ring 7 is inserted into the sleeve 6. Then the threaded rod 15 is turned. As the threaded rod 15 rotates in the threaded hole 9, the length of the threaded rod 15 located in the chute 8 becomes longer, and gradually the support block 10 slides out of the chute 8, and the rubber gasket 11 contacts the inner wall of the sleeve 6. When the threaded rod 15 cannot be rotated, the installation is completed. The elastic force of the rubber gasket 11 makes the threaded rod 15 fit more tightly with the threaded hole 9. When disassembling, by rotating the threaded rod 15 in the reverse direction, the length of the threaded rod 15 located in the chute 8 becomes shorter, and at this time the support block 10 is gradually driven by the threaded rod 15 into the chute 8, separating the rubber gasket 11 from the sleeve 6. At this time, the fixed steel ring 7 can be taken out, and when the fixed steel ring 7 is taken out, the outer ring 3 is taken out.

[0028] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
