[0002] A bearing that has been in operation for a long time needs to be replaced due to wear and tear and damage. Before replacement, the bearing needs to be dismounted first. In the process of dismounting the bearing, the rolling elements, inner ring and retainer of the bearing are relatively easy to dismount, while the outer ring is difficult to dismount because of the interference fit between the outer ring and the mounting hole of the bearing seat.

[0003] In the related art, the outer ring of the bearing is usually dismounted by violent means, i.e. the outer ring is cut and disassembled for removal. This method not only damages the outer ring of the bearing, but also easily damages the hole wall of the mounting hole on the bearing seat. CONTENT OF THE UTILITY MODEL

In addition, the character " / " in this paper generally represents that the front and rear associated objects have an "or" relationship.

[0059] The bearing that has been in operation for a long time will be replaced due to wear, damage, etc. For example, the bearing that has an abnormality is replaced during maintenance. For another example, the bearing that reaches a predetermined service life is replaced preventively during periodic maintenance, to ensure the working reliability of the bearing. Before replacement, the bearing needs to be disassembled first. In the process of disassembling the bearing, the rolling elements, the inner ring and the cage of the bearing are relatively easy to disassemble. However, the outer ring of the bearing is difficult to disassemble because there is an interference fit between the mounting hole of the bearing and the bearing seat.

[0060] In the related art, the bearing outer ring is usually cut and disassembled for removal by violent disassembly. This method not only damages the bearing outer ring, but also easily damages the hole wall of the mounting hole on the bearing seat.

[0061] To solve the above technical problems, the application provides a bearing outer ring dismounting device. The bearing outer ring dismounting device provided by the application is described in detail below with reference to the accompanying drawings.

[0062] Reference Figures 1 to 5 The application provides a bearing outer ring dismounting device 1, which comprises a support 100, a lifting screw 200, a clamping mechanism 300, and a locking mechanism 400. The lifting screw 200 is threadedly connected with the support 100 and can move along a preset direction X relative to the support 100. The clamping mechanism 300 is connected with the lifting screw 200. The clamping mechanism 300 comprises two clamping arms 310 that are cross-connected and rotatably connected. The clamping arm 310 comprises a force applying segment 311 and a clamping segment 312 that are connected. The clamping segment 312 has a clamping jaw 3120. The locking mechanism 400 is detachably connected with the force applying segment 311 to lock the clamping segment 312.

[0063] The support 100 is used to support the lifting screw 200, the clamping mechanism 300, and the locking mechanism 400. The lifting screw 200 is threadedly connected with the support 100 and rotates relative to the support 100 under the action of an external force and moves along the preset direction X. For example, the lifting screw 200 can move upward or downward along the up-down direction in the figure. Figure 1 The clamping mechanism 300 is connected with the lifting screw 200 and can move along the preset direction X relative to the support 100 together with the lifting screw 200.

[0064] The two clamping arms 310 of the clamping mechanism 300 are cross-connected and rotatably connected. Each clamping arm 310 is provided with a clamping segment 312 and a force applying segment 311. Each clamping segment 312 is provided with a clamping jaw 3120. The two clamping jaws 3120 can be arranged on two opposite sides of the two clamping segments 312, respectively. In the clamping mechanism 300, the two clamping jaws 3120 are used to hook the end face of the bearing outer ring. The two force applying segments 311 can rotate relative to each other, thereby driving the two clamping segments 312 and the clamping jaws 3120 thereon to rotate relative to each other.

[0065] The locking mechanism 400 is at least partially arranged between the two force applying segments 311. The locking mechanism 400 acts on the two force applying segments 311 and can drive the two force applying segments 311 to drive the two clamping segments 312 and the clamping jaws 3120 thereon to rotate relative to each other, so that the clamping jaws 3120 tightly hook the end face of the bearing outer ring, thereby achieving the locking of the clamping jaws 3120.

[0066] When using the bearing outer ring removal device 1, first fix the bracket 100; then, use the locking mechanism 400 to act on the two force-applying sections 311 to lock the two clamping jaws 3120, so that the two clamping jaws 3120 always tightly hook the end face of the bearing outer ring during the removal of the bearing outer ring; then, by rotating the lifting screw 200, the lifting screw 200 drives the clamping mechanism 300 and the bearing outer ring to move along the preset direction X, and finally the bearing outer ring is separated from the mounting hole of the bearing seat, completing the removal of the bearing outer ring.

[0067] The solution provided in the embodiment of the present application is to lock the clamping jaws 3120 of the clamping section 312 by means of the locking mechanism 400 acting on the force-applying sections 311 of the two clamping arms 310 in the clamping mechanism 300, so that the two clamping jaws 3120 tightly hook the end face of the bearing outer ring. Furthermore, by rotating the lifting screw 200, the lifting screw 200 drives the clamping mechanism 300, in which the clamping jaws 3120 tightly hook the end face of the bearing outer ring, and the bearing outer ring to move along a preset direction X, thereby enabling the bearing outer ring to be separated from the mounting hole of the bearing seat. Because violent disassembly of the bearing outer ring is avoided, there is no need to cut and disassemble the bearing outer ring, and the wall of the mounting hole of the bearing seat will not be damaged during cutting and disassembly. Therefore, the solution of the present application can avoid damaging the bearing outer ring and the wall of the mounting hole of the bearing seat during disassembly, thereby achieving non-destructive disassembly of the bearing outer ring.

[0068] See also Figure 2 In some implementations, the bracket 100 includes a support member 120 and at least two support rods 110; the support member 120 is fixedly arranged at one end of the support rod 110, and the support member 120 is provided with a first threaded hole 121 threadedly connected to the lifting screw 200. Considering the complex environment and limited space at the work site, in order to facilitate the disassembly of the outer ring of the bearing, the embodiment of the present application adopts the form of supporting the support member 120 by the support rod 110, one end of the support rod 110 is connected to the support member 120, and the other end can be fixed by manual pressing or spot welding. The rod-shaped structure of the support rod 110 has the advantages of taking up little space and being easy to obtain and manufacture. The number of support rods 110 can be as follows Figure 2 The two shown are, of course, three, four, and so on. Support rod 110 can be made of a high-strength metal material, such as rebar, steel pipe, etc. Furthermore, a magnetic element or suction cup (not shown) can be provided at the other end of support rod 110. This allows the magnetic element or suction cup to be conveniently and quickly attached to the mounting location before removing the bearing outer ring, enabling rapid installation of the bearing outer ring removal device 1 of the present application.

[0069] See also Figure 3 In some implementations, a clamping portion 210 is provided at one end of the lifting screw 200 away from the clamping mechanism 300. Figure 3As shown, the clamping portion 210 can be a prism with a hexagonal cross-section. The six parallel edges of the prism facilitate gripping with tools such as wrenches and pliers, making it easier for workers to apply external force to the lifting screw 200. By gripping and rotating the clamping portion 210 with a tool, the lifting screw 200 can be rotated and moved in a predetermined direction X.

[0070] Considering that the lifting screw 200 is threadedly connected to the bracket 100, it is necessary to rotate the lifting screw 200 to achieve the movement of the lifting screw 200 along the preset direction X. In order to prevent the lifting screw 200 connected to the clamping mechanism 300 from rotating while driving the clamping mechanism 300 to rotate, causing the clamping claw 3120 to move relative to the outer ring of the bearing, the embodiment of the present application adopts a movable connection to connect the lifting screw 200 and the clamping mechanism 300. For example, see Figure 3 and Figure 4 In some embodiments, a stop portion 220 may be provided at one end of the lifting screw 200 close to the clamping mechanism 300; the bearing outer ring disassembly device 1 may further include a connecting frame 500, one end of the connecting frame 500 is connected to the clamping mechanism 300, and the other end of the connecting frame 500 is sleeved on the lifting screw 200 and overlapped on the stop portion 220. In this way, the connecting frame 500 sleeved on the lifting screw 200 can overlap on the stop portion 220. Since the connecting frame 500 and the stop portion 220 are not fixedly connected, when the lifting screw 200 rotates, the lifting screw 200 can rotate relative to the connecting frame 500, and will not drive the clamping mechanism 300, and further will not cause relative movement between the clamping claw 3120 and the bearing outer ring. Among them, the stop portion 220 may be a separate structural component. For example, the stop portion 220 may be the head at one end of the lifting screw 200, such as Figure 3 As shown, the head can be a hexagonal head, or a round head. In this case, the outer dimensions of the stopper 220 are larger than the diameter of the lifting screw 200. The portion of the stopper 220 that protrudes beyond the lifting screw 200 can form a step that provides support. Alternatively, the stopper 220 can be at least one protruding structure on the circumference of the lifting screw 200, which itself can serve as a step that provides support.

[0071] The connecting frame 500 can have various structural forms. Figure 5 As shown, in some embodiments, the connecting frame 500 may include a connecting plate 520 and two vertical plates 510. The two vertical plates 510 are spaced apart on both sides of the clamping mechanism 300, and the vertical plates 510 are connected to the clamping mechanism 300; the connecting plate 520 is connected to the two vertical plates 510, and a through hole 521 is opened in the middle of the connecting plate 520. The connecting plate 520 is sleeved on the lifting screw 200 through the through hole 521 and overlapped with the stopper 220. The vertical plate 510 and the clamping mechanism 300 can be fixedly connected by welding or other methods. In addition, seeFigure 5 The stand plate 510 can also be provided with a plug hole 511. The threaded stud is inserted into the plug hole 511 and locked with the nut to fix the clamping mechanism 300. When the stopper 220 is provided with a hexagonal head as shown in Figure 3 , the diameter of the through hole 521 of the connecting plate 520 is larger than the diameter of the lifting screw 200 but smaller than the outer dimension of the stopper 220. When the stopper 220 is provided with a protruding structure around the lifting screw 200, there is no gap between the protruding structure and the hole wall of the through hole 521. In this way, the connecting plate 520 is connected to the lifting screw 200 and can rotate relative to the lifting screw 200 under the block of the stopper 220, realizing the movable connection between the lifting screw 200 and the clamping mechanism 300.

[0072] In order to improve the firmness of the rotating connection of the two clamping arms 310 of the clamping mechanism 300, referring to Figure 4 , in some embodiments, the clamping arm 310 can also include a reinforcing section 313 fixedly arranged between the force applying section 311 and the clamping section 312, and the reinforcing section 313 is provided with a connecting hole 3130; the two clamping arms 310 are rotatably connected by the rotating shaft 320 inserted into the connecting hole 3130. Compared with the force applying section 311 and the clamping section 312, the structural strength of the reinforcing section 313 is strengthened by selecting a higher strength material and optimizing the structural design of the reinforcing section 313. For example, the reinforcing section 313 can be made of high-strength steel. As shown in Figure 4 , the reinforcing section 313 can also adopt a disc structure to reduce stress concentration.

[0073] In order to improve the compactness of the structure of the clamping mechanism 300, referring to Figure 1 and Figure 4 , in some embodiments, the two opposite sides of the reinforcing section 313 are provided with a thinning area 3131; one reinforcing section 313 fills the thinning area 3131 of the other reinforcing section 313. Among them, the thickness of the reinforcing section 313 can be set to be smaller than the thickness of the force applying section 311 and the thickness of the clamping section 312, so that the thinning area 3131 of the reinforcing section 313 forms a recessed area between the force applying section 311 and the clamping section 312. When the two opposite sides of the two reinforcing sections 313 are provided with the thinning area 3131, the two reinforcing sections 313 can fill each other's thinning area 3131, effectively reducing the thickness of the clamping mechanism 300 and improving the compactness of the structure of the clamping mechanism 300.

[0074] As described above, the locking mechanism 400 acts on the force applying section 311 of the two clamping arms 310, which can make the two clamping jaws 3120 on the two clamping sections 312 tightly hook the end face of the bearing outer ring. Referring to Figure 1 and Figure 4In some embodiments, one of the two force applying segments 311 is provided with a second threaded hole 3110, the axis of the second threaded hole 3110 extending towards the other force applying segment 311; the locking mechanism 400 comprises a locking screw 410, which is threadedly connected with the second threaded hole 3110. Part of the locking screw 410 is located between the two force applying segments 311. The locking screw 410 is movable along the axis of the second threaded hole 3110 and abuts against the other force applying segment 311. When the locking screw 410 cannot continue to move along the axis of the second threaded hole 3110 towards the other force applying segment 311, it is considered that the two clamping jaws 3120 have been tightly hooked to the end face of the bearing outer ring under the pressing action of the locking screw 410, and the locking of the two clamping jaws 3120 is achieved.

[0075] In other embodiments, the locking mechanism 400 can further comprise a compression spring (not shown in the figure) on the basis of the above-mentioned locking screw 410, or can only comprise a compression spring. In either case, the compression spring is fixedly arranged between the two force applying segments 311. Moreover, one end of the compression spring can be fixedly connected with one force applying segment 311, and the other end of the compression spring can be fixedly connected with the other force applying segment 311. When the locking mechanism 400 further comprises a compression spring on the basis of the above-mentioned locking screw 410, the compression spring can press against the two force applying segments 311 in a free state, providing certain assistance force to facilitate the tightening of the locking screw 410 by the worker. When the locking mechanism 400 only comprises a compression spring, the specification size and the elastic coefficient of the compression spring are relatively large, and the compression spring can generate relatively large spring force. In this case, the spring force generated by the compression spring acts on the force applying segments 311 of the two clamping arms 310, so that the two clamping jaws 3120 on the two clamping segments 312 can be tightly hooked to the end face of the bearing outer ring. In either case, the designer can determine the specification size, the elastic coefficient and the specific mounting position of the compression spring through simulation, test and the like, and the present application embodiments do not make specific limitations thereon.
