[0032] When maintaining the equipment for manufacturing wet diaphragms, in order to reduce the difficulty of bearing disassembly, improve the replacement efficiency, and reduce the maintenance cost, as Figure 1 - Figure 2 shown, the present utility model provides a bearing quick disassembly device. The bearing quick disassembly device includes a bottom plate 1, at least two groups of pull rod assemblies 3, and a telescopic quick disassembly assembly 2.

[0033] Among them, the pull rod assembly 3 is slidably arranged on the bottom plate 1. The pull rod assembly 3 includes a pull rod body 31 and a clamping part 32. One end of the pull rod body 31 is connected to the bottom plate 1, and the other end of the pull rod body 31 is detachably connected to the clamping part 32. The pull rod body 32 can pass through the bearing clearance between the inner ring and the outer ring of the bearing 5, and the clamping part 32 abuts against the side of the bearing 5 away from the bottom plate 1. The telescopic quick-release assembly 2 is arranged on the bottom plate 1, and the telescopic quick-release assembly 2 can abut against the end of the mounting shaft 4 on which the bearing 5 is installed.

[0034] When disassembling the bearing 5, the clamping part 32 is abutted against the side of the bearing 5 away from the bottom plate 1, and then the telescopic quick-release assembly 2 can extend to push the bottom plate 1 away from the mounting shaft 4. The bottom plate 1 drives the pull rod assembly 3 to move during this process, so as to remove the bearing 5 from the mounting shaft 4. By using the present bearing quick-disassembly device to disassemble the bearing 5, the difficulty of disassembling the bearing 5 can be reduced, the replacement efficiency can be improved, and the maintenance cost of the equipment can be reduced.

[0035] In some embodiments, the pull rod assembly 3 can rotate relative to the bottom plate 1 with its own axis as the center; when the pull rod assembly 3 rotates to the first position, the width of the end of the clamping part 32 away from the bottom plate 1 in the radial direction of the bearing 5 is smaller than the bearing clearance, so that the clamping part 32 can pass through the bearing clearance; when the pull rod assembly 3 rotates to the second position, the width of the end of the clamping part 32 away from the bottom plate 1 in the radial direction of the bearing 5 is larger than the bearing clearance, so that the clamping part 32 can be clamped with the bearing 5. Through the above settings, it is convenient for the pull rod assembly 3 to pass through the bearing clearance and then rotate to the second position to abut against the side of the bearing 5 away from the bottom plate 1. By adopting the above method, the operation difficulty is reduced, and it is convenient for the pull rod assembly 3 to quickly abut against or disengage from the bearing 5.

[0036] In some embodiments, the included angle between the first position and the second position is 5°-30°. The pull rod body 31 is inserted into the bearing clearance at the first position, and then rotated to the second position at a small angle, and the clamping part 32 can be abutted against the bearing.

[0037] In some embodiments, two barbs 322 extend from the end of the clamping part 32 away from the bottom plate 1 to both sides. When the pull rod assembly 3 rotates to the second position, the two barbs 322 can respectively abut against the outer ring and the inner ring of the bearing 5. By arranging the barbs 322, it can be ensured that when the clamping part 32 is in the second position, it can stably cooperate with the inner ring and the outer ring of the bearing 5, so as to facilitate the subsequent removal of the bearing 5.

[0038] In some embodiments, the pull rod body 31 is detachably connected to the clamping part 32. By adopting the form of detachable connection, the corresponding clamping part 32 can be selected according to the model of the bearing 5, so that the replacement of the clamping part 32 can be quickly completed according to the actual needs, and the efficiency of disassembling the bearing 5 is ensured.

[0039] In some embodiments, the base plate 1 is provided with a movable plate 11 which can slide out from the base plate 1. The pull rod assembly 3 is installed on the movable plate 11, and the pull rod assembly 3 can rotate from the first position to the second position. By providing the movable plate 11, it can be flexibly adjusted according to the model of the bearing 5. With the cooperation of the base plate 1 and the movable plate 11, it can adapt to the disassembly work of bearings 5 with different diameters, improving the flexibility of the use of this bearing quick disassembly device.

[0040] In some embodiments, a locking member is provided on the base plate 1, and the locking member is used to lock the relative position between the movable plate 11 and the base plate 1. Specifically, the locking member can be a screw, which is screwed to the base plate 1 and can abut against the movable plate 11. When disassembling the bearing 5, first adjust the extending length of the movable plate 11 relative to the base plate 1 according to the diameter of the bearing 5, and then use the locking member to lock the position of the movable plate 11 relative to the base plate 1. By providing the locking member, the relative position between the movable plate 11 and the base plate 1 can be ensured to be stable, thus ensuring the accuracy of the position for installing the pull rod assembly 3 subsequently, and further ensuring the smooth progress of the disassembly work of the bearing 5.

[0041] In some embodiments, an installation groove 311 is formed on the pull rod body 31, and the pull rod body 31 is installed on the base plate 1 through the installation groove 311. Specifically, in this embodiment, the installation groove 311 is located at one end of the pull rod body 31 away from the clamping portion 32, and the depth of the installation groove 311 is half of the diameter of the pull rod body 31, which can ensure that the pull rod body 31 is stably hung on the floor through the installation groove 311. The diameter of the pull rod body 31 can be determined according to the clearance between the inner ring and the outer ring of the bearing 5, as long as it can be inserted between the inner ring and the outer ring of the bearing 5, and no more restrictions are made here.

[0042] In some embodiments, the pull rod body 31 is threadedly connected or snap-connected to the clamping portion 32. In this embodiment, a threaded hole is formed on one of the pull rod body 31 and the clamping portion 32, and a connecting screw rod 321 is provided on the other of the pull rod body 31 and the clamping portion 32, and the connecting screw rod 321 is screwed to the threaded hole. Specifically, a threaded hole is formed at one end of the pull rod body 31 facing the clamping portion 32, and a connecting screw rod 321 is provided at one end of the clamping portion 32 facing the pull rod body 31. By adopting the form of threaded connection, it can ensure the quick disassembly and assembly between the pull rod body 31 and the clamping portion 32, so as to meet the needs of disassembling different models of bearings 5. Moreover, through the form of threaded connection, the connection strength between the pull rod body 31 and the clamping portion 32 can be ensured. In other embodiments, the clamping portion 32 and the pull rod body 31 can also adopt the form of plug connection, and no more restrictions are made here.

[0043] In some embodiments, the telescopic quick-release assembly 2 includes a hydraulic cylinder 21 fixedly arranged on the bottom plate 1, and the piston rod of the hydraulic cylinder 21 can abut against the end of the mounting shaft 4. During the disassembly of the bearing 5, it is only necessary to adjust the extension length of the piston rod to disassemble the bearing 5 from the mounting shaft 4. Moreover, since the hydraulic cylinder 21 can output a large force, it can effectively remove the bearing 5 from the mounting shaft 4. In this embodiment, the hydraulic cylinder 21 is an electronically controlled hydraulic cylinder, which is convenient for controlling the extension and retraction of the piston rod of the hydraulic cylinder 21. In other embodiments, an air cylinder or an electric cylinder can also be used instead of the hydraulic cylinder 21, which will not be limited here too much.

[0044] In some embodiments, a contact member 22 is fixedly arranged at the end of the piston rod of the hydraulic cylinder 21, and the area of the contact member 22 is larger than the cross-sectional area of the piston rod. By providing the contact member 22, the contact area between the end of the piston rod of the hydraulic cylinder 21 and the end of the mounting shaft 4 can be increased. Thus, during the disassembly of the bearing 5, the pressure acting on the end of the mounting shaft 4 can be dispersed, avoiding the end of the mounting shaft 4 from being crushed or damaged.

[0045] In some embodiments, the materials of the bottom plate 1 and the pull rod assembly 3 are stainless steel. By using stainless steel, the bottom plate 1 and the pull rod assembly 3 can be prevented from being corroded, ensuring the service life of the bearing quick-disassembly device. In other embodiments, an anti-rust paint can also be applied to the bottom plate 1 and the pull rod assembly 3 to protect the bottom plate 1 and the pull rod assembly 3.

[0046] The use process of this bearing quick-disassembly device is as follows:

[0047] First, adjust the extension length of the movable plate 11 relative to the bottom plate 1 according to the diameter of the bearing 5 and lock it with the locking member. Then, suspend the pull rod assembly 3 at the first position, and make the clamping portion 32 of the pull rod assembly 3 pass through the bearing clearance from the damaged part of the cage of the bearing 5, and rotate the pull rod assembly 3 to the second position so that the clamping portion 32 abuts against the outer ring and the inner ring of the bearing 5. Start the hydraulic cylinder 21 so that the piston rod of the hydraulic cylinder 21 abuts against the mounting shaft 4 and continues to extend, so that the bottom plate 1 moves away from the mounting shaft 4. Driven by the bottom plate 1, the pull rod assembly 3 drives the bearing 5 to be removed from the mounting shaft 4, completing the disassembly work of the bearing 5.

[0048] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
