[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0022] Example

[0023] This utility model provides a device for installing pressure roller bearings, such as... Figures 1-4 As shown, the bearing mounting base 1 is U-shaped and integrally formed, made of cast iron. Mounting holes 4 are provided on both horizontal sections of the bearing mounting base 1. A pressure roller 3 is installed within the U-shaped area 2 of the bearing mounting base 1. A rotating hole is provided on the end face of the pressure roller 3, with its central axis coaxial with the central axis of the circle containing the pressure roller 3, and also coaxial with the mounting hole 4. A first bearing structure 11 is installed within the rotating hole, and a rotating shaft 8 passes through the mounting hole 4. The rotating shaft 8 is detachably connected to the first bearing structure 11. To disassemble the structure, the rotating shaft 8 must first be pulled out of the rotating hole on the bearing mounting base 1. At this point, the pressure roller 3 separates from the bearing mounting base 1; simply remove the pressure roller 3 from the bearing mounting base 1. Then, the first bearing structure 11 can be removed from the rotating hole using specialized bearing disassembly tools. The operator can then reverse the process to install the pressure roller 3 within the U-shaped area of ​​the bearing mounting base 1. The first bearing structure 11 is installed inside the pressure roller 3 by the above structure, which facilitates disassembly later. When maintaining the pressure roller 3, it is not necessary to disassemble the bearing mounting seat 1 together with the pressure roller 3, simplifying the disassembly process and improving disassembly efficiency. The above structure, by installing the first bearing structure 11 inside the pressure roller 3, avoids the problem of the rotating shaft 8 directly contacting the inner wall of the pressure roller 3, which would aggravate the wear of the pressure roller 3, and can effectively extend the service life of the pressure roller 3.

[0024] In some technical schemes of the utility model, the first bearing structure 11 includes bearing inner ring 5 and bearing outer ring 6. The bearing inner ring 5 and the bearing outer ring 6 are annular structures, the bearing inner ring 5 is installed in the bearing outer ring 6, and the bearing inner ring 5 is installed with ball structure 12 between the bearing outer ring 6. The bearing formed by the above structure can be a load bearing or a ball bearing, and the first bearing structure 11 is a conventional technical means. The bearing inner ring 5 is detachably connected with the rotating shaft 8, and the bearing outer ring 6 is detachably connected with the rotating hole.

[0025] In some technical schemes of the utility model, a limiting hole is formed in the outer side wall of the bearing mounting seat 1, the limiting hole is communicated with the mounting hole 4, a limiting shaft 9 is installed in the limiting hole, and the limiting shaft 9 is partially embedded in the rotating shaft 8. The limiting shaft 9 is in interference fit with the limiting hole. After the rotating shaft 8 is inserted into the mounting hole 4, the outer wall of the rotating shaft 8 is attached to the inner wall of the mounting hole 4, the limiting shaft 9 installed on the outer side wall of the bearing mounting seat 1 can be used to prevent the rotating shaft 8 from rotating, and the rotating shaft 8 can be prevented from retreating in the mounting hole 4, thereby ensuring the stability of the compression roller 3 when the compression roller 3 relies on the rotating shaft 8 and the first bearing structure 11 to run on the bearing mounting seat 1.

[0026] In some technical schemes of the utility model, the limiting shaft 9 is in threaded connection with the limiting hole. The limiting effect of the limiting shaft 9 on the rotating shaft 8 can be further improved, that is, the rotation and axial retreat of the rotating shaft 8 are inhibited, the running stability is ensured, and the connection strength of the limiting shaft 9 and the bearing mounting seat 1 is improved.

[0027] In some technical schemes of the utility model, an external thread is formed in the outer side wall of the bearing outer ring 6, and an internal thread in threaded connection with the external thread is formed in the inner wall of the rotating hole. In this way, the bearing outer ring 6 can be prevented from rotating in the rotating hole, and the stability of the compression roller 3 when the compression roller 3 relies on the rotating shaft 8 and the first bearing structure 11 to run on the bearing mounting seat 1 is ensured.

[0028] In some technical schemes of the utility model, a prismatic sleeve 7 is sleeved on the outer side wall of the rotating shaft 8, and the outer cross section of the prismatic sleeve 7 is a hexagonal prism or a triangular prism or a pentagonal prism. A groove structure adapted to the prismatic sleeve 7 is formed in the inner side wall of the bearing inner ring 5. The relative rotation is prevented through non-circular cross section geometric locking; the bearing outer ring 6 is fixed through threads and the rotating hole, and the double anti-rotation mechanism enhances the stability. The bearing outer ring 6 can be prevented from rotating in the rotating hole, and the stability of the compression roller 3 when the compression roller 3 relies on the rotating shaft 8 and the first bearing structure 11 to run on the bearing mounting seat 1 is ensured.

[0029] In some technical schemes of the utility model, the bearing mounting seat 1 is provided with a limiting sleeve 10 in the " " shaped area, and a second bearing structure is detachably connected with the limiting sleeve 10 in the rotating hole. The limiting sleeve 10 can support the bottom of the compression roller 3, prevent the compression roller 3 from moving up and down on the outer side wall of the rotating shaft 8, balance the load distribution, prolong the service life of the bearing, and ensure the stability of the compression roller 3 when relying on the rotating shaft 8 and the first bearing structure 11 to run on the bearing mounting seat 1.

[0030] Preferably, the second bearing structure is the same as the first bearing structure 11. The second bearing structure is standardized (bearing or ball bearing), which can be quickly replaced and maintained, and the maintenance cost is reduced.

[0031] In some technical schemes of the utility model, two dustproof rings are sleeved on the outer side wall of the rotating shaft 8. The installation of the dustproof ring is not shown in the figure. The two dustproof rings are located on both sides of the compression roller 3, and the local dustproof ring is embedded in the rotating hole. The material of the dustproof ring is rubber material, and the dustproof ring can prevent dust from entering the rotating hole, which can prolong the service life of the first bearing structure 11 and the second bearing structure.
