Description

Technical Field

[0001] This utility model belongs to the field of bearing technology, specifically relating to an inner ring split double row asymmetric self-lubricating tapered bearing. Background Art

[0002] Split-ring bearings typically consist of a single outer ring, with an inner ring housed within it. Split-ring bearings offer advantages such as ease of on-site installation and the ability to replace individual bearing components. Currently, most split-ring bearings typically have two inner rings mounted inside the outer ring, positioned at opposite ends of the outer ring and using a tapered surface contact method. This allows them to simultaneously withstand radial and axial forces. However, during operation, the bearing experiences a greater axial force on one side, which can easily lead to severe wear on that side, affecting the overall service life of the bearing. Utility Model Content

[0003] This utility model provides an inner ring split double-row asymmetric self-lubricating tapered roller bearing, which aims to solve the problem that the service life of the existing split bearing is affected when it is subjected to a large axial force on one side.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an inner ring split type double row asymmetric self-lubricating tapered roller bearing, comprising:

[0005] The outer ring has a first tapered hole and a second tapered hole at its two ends, respectively. The first tapered hole and the second tapered hole are coaxially arranged. The taper of the first tapered hole is greater than that of the second tapered hole, and the smaller inner diameter of the first tapered hole and the second tapered hole is located inside the outer ring.

[0006] The first inner ring is rotatably disposed inside the first conical hole, and the outer wall of the first inner ring is a conical structure adapted to the first conical hole;

[0007] The second inner ring is rotatably disposed inside the second conical hole, and the outer wall of the second inner ring is a conical structure adapted to the second conical hole.

[0008] In one possible implementation, an adjustment ring is further installed between the first inner ring and the second inner ring, with the ends of the first inner ring and the second inner ring respectively abutting against the two ends of the adjustment ring.

[0009] In one possible implementation, the outer ring has a mounting hole in the middle for mounting the adjustment ring, and the mounting hole is connected to the first tapered hole and the second tapered hole respectively.

[0010] In one possible implementation, the inner diameters of the first inner ring and the second inner ring are the same and coaxially arranged, and the inner diameter of the adjusting ring is greater than the inner diameters of the first inner ring and the second inner ring.

[0011] In one possible implementation, the outer diameter of the adjusting ring is smaller than the inner diameter of the mounting hole on the outer ring.

[0012] In one possible implementation, the outer surface of the outer ring is coaxially arranged with the inner holes of the first inner ring and the second inner ring.

[0013] In one possible implementation, a first tapered gasket is slidably connected between the first inner ring and the first tapered hole, and a second tapered gasket is slidably connected between the second inner ring and the second tapered hole.

[0014] In one possible implementation, the first conical pad is entirely located inside the first conical hole, and the second conical pad is entirely located inside the second conical hole.

[0015] The solution shown in this application, compared with the prior art, features an outer ring with a first tapered hole and a second tapered hole inside. The first and second tapered holes are coaxially arranged, with the larger inner diameter ends of the first and second tapered holes located at opposite ends of the outer ring. This allows the first and second inner rings to be installed into the first and second tapered holes, respectively. Furthermore, after the first and second inner rings are installed into the outer ring, the inner holes of the first and second inner rings are coaxial and have the same dimensions. This application, by providing first and second tapered holes with different tapers at both ends of the outer ring, increases the axial load-bearing capacity at one end of the outer ring within a limited size range. In use, the end with the first tapered hole can be placed against the end subjected to greater force. Because the first tapered hole has a larger taper, it can withstand a larger axial load, reducing wear on the side of the bearing subjected to greater force and thus stabilizing the bearing's service life.

[0019] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please see Figure 1 The present invention provides a split-type double-row asymmetric self-lubricating tapered bearing with an inner ring. The split-type double-row asymmetric self-lubricating tapered bearing includes an outer ring 1, a first inner ring 2, and a second inner ring 3. The outer ring 1 has a first tapered hole and a second tapered hole at its two ends, respectively. The first and second tapered holes are coaxially arranged, with the taper of the first tapered hole being greater than that of the second tapered hole. The smaller inner diameter end of the first and second tapered holes is located inside the outer ring 1. The first inner ring 2 is rotatably disposed inside the first tapered hole, and its outer side wall is a tapered structure adapted to the first tapered hole. The second inner ring 3 is rotatably disposed inside the second tapered hole, and its outer side wall is a tapered structure adapted to the second tapered hole.

[0021] The inner ring split-type double-row asymmetric self-lubricating tapered bearing provided in this embodiment, compared with the prior art, features an outer ring 1 with a first tapered hole and a second tapered hole inside. The first and second tapered holes are coaxially arranged, with the larger inner diameter ends of the first and second tapered holes located at opposite ends of the outer ring 1. This allows the first inner ring 2 and the second inner ring 3 to be installed into the first and second tapered holes, respectively. Furthermore, after the first inner ring 2 and the second inner ring 3 are installed inside the outer ring 1, the inner holes of the first inner ring 2 and the second inner ring 3 are coaxial and have the same dimensions. This application, by providing first and second tapered holes with different tapers at opposite ends of the outer ring 1, increases the axial load capacity at one end of the outer ring 1 within a limited size range. In use, the end with the first tapered hole can be placed against the end subjected to greater force. Because the first tapered hole has a larger taper, it can withstand a larger axial load, reducing wear on the side of the bearing subjected to greater force and thus stabilizing the bearing's service life.

[0022] Specifically, in this embodiment, during on-site installation, the outer ring 1 can be installed first.

[0023] In some embodiments, the first inner ring 2 and the second inner ring 3 may be adopted as follows: Figure 1 The structure shown. See also Figure 1An adjusting ring 4 is installed between the first inner ring 2 and the second inner ring 3, with the ends of the first inner ring 2 and the second inner ring 3 respectively abutting against the two ends of the adjusting ring 4. The adjusting ring 4 is located inside the outer ring 1 and in its middle. When the first inner ring 2 and the second inner ring 3 are installed inside the outer ring 1, the ends of the first inner ring 2 and the second inner ring 3 abut against the two ends of the adjusting ring 4, thus limiting the position of the first inner ring 2 and the second inner ring 3. This ensures the clearance between the first inner ring 2, the second inner ring 3 and the first and second tapered holes. When the clearance needs to be adjusted, the thickness of the adjusting ring 4 can be changed to adjust the position of the first inner ring 2 and the second inner ring 3 inside the first and second tapered holes along the axis of the outer ring 1, thereby achieving the purpose of adjusting the clearance.

[0024] In some embodiments, the outer ring 1 described above can be as follows: Figure 1 The structure shown. See also Figure 1 The outer ring 1 has a mounting hole in its center for installing the adjusting ring 4. This mounting hole communicates with both the first and second tapered holes. The mounting hole is coaxial with both the first and second tapered holes. When the first inner ring 2 and the second inner ring 3 are installed into the first and second tapered holes respectively, the ends of the first inner ring 2 and the second inner ring 3 can slide into the mounting hole. This provides a buffer for the positions of the first inner ring 2 and the second inner ring 3, facilitating adjustment of the clearance between the first inner ring 2, the second inner ring 3, and the outer ring 1.

[0025] Specifically, in this embodiment, the mounting hole is designed to facilitate the installation of the adjustment ring 4, so that the adjustment ring 4 can be installed between the first inner ring 2 and the second inner ring 3.

[0026] In some embodiments, the first inner ring 2 and the second inner ring 3 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 The first inner ring 2 and the second inner ring 3 have the same inner hole size and are coaxially arranged, and the inner diameter of the adjusting ring 4 is larger than the inner diameters of the first inner ring 2 and the second inner ring 3. The identical inner hole size of the first inner ring 2 and the second inner ring 3 allows them to be installed on the same shaft, thus facilitating various installation conditions. Simultaneously, the larger inner diameter of the adjusting ring 4 prevents interference with the shaft installation during the installation of the first inner ring 2 and the second inner ring 3.

[0027] In some embodiments, the adjustment ring 4 described above can be adopted as follows: Figure 1 The structure shown. See also Figure 1The outer diameter of the adjusting ring 4 is smaller than the inner diameter of the mounting hole on the outer ring 1. When the adjusting ring 4 is installed inside the mounting hole, there is a gap between the outer surface of the adjusting ring 4 and the inner wall of the mounting hole. When the first inner ring 2 and the second inner ring 3 rotate relative to the outer ring 1, the adjusting ring 4 can be clamped between the first inner ring 2 and the second inner ring 3 and rotate with the first inner ring 2 and the second inner ring 3. This avoids increased friction caused by the outer surface of the adjusting ring 4 contacting the inner wall of the mounting hole, thus improving the smoothness of the bearing during use.

[0028] In some embodiments, the outer ring 1 described above can be as follows: Figure 1 The structure shown. See also Figure 1 The outer surface of the outer ring 1 is coaxially arranged with the inner holes of the first inner ring 2 and the second inner ring 3. When the first inner ring 2 and the second inner ring 3 are installed inside the first tapered hole and the second tapered hole, the outer surface of the outer ring 1 is coaxially arranged with the first inner ring 2 and the second inner ring 3. The outer ring 1 can be directly installed into the mounting hole at the installation position, and the shaft can be installed into the first inner ring 2 and the second inner ring 3. The structure is simple and facilitates the installation of the bearing.

[0029] In some embodiments, the first inner ring 2 and the second inner ring 3 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 A first conical gasket 5 is slidably connected between the first inner ring 2 and the first conical bore, and a second conical gasket 6 is slidably connected between the second inner ring 3 and the second conical bore. Both the first conical gasket 5 and the second conical gasket 6 are conical sleeves. The inner bore of the first conical gasket 5 is slidably engaged with the outer wall of the first inner ring 2, and the outer wall of the first conical gasket 5 is slidably engaged with the inner wall of the first conical bore. The use of the first conical gasket 5 and the second conical gasket 6 reduces the overall size of the bearing. It also facilitates the subsequent connection between the first inner ring 2, the second inner ring 3, and the outer ring 1.

[0030] Specifically, in this embodiment, the second conical gasket 6 is installed in the same way as the first conical gasket 5.

[0031] Specifically, in this embodiment, the first conical gasket 5 and the second conical gasket 6 are made of PTFE material or copper sleeve.

[0032] In some embodiments, the first conical pad 5 and the second conical pad 6 described above can be adopted as follows: Figure 1 The structure shown. See also Figure 1The first conical gasket 5 is entirely located inside the first conical hole, and the second conical gasket 6 is entirely located inside the second conical hole. When the first conical gasket 5 is installed inside the first conical hole, its outer surface is entirely fitted against the inner wall of the first conical hole. When the first inner ring 2 is installed inside the first conical gasket 5, its outer surface is entirely fitted against the inner wall of the first conical gasket 5. Furthermore, the fact that the first conical gasket 5 is entirely located inside the first conical hole provides protection for it.

[0033] Specifically, in this embodiment, the second conical gasket 6 is installed in the same way as the first conical gasket 5.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
