[0028] All terms used in the present disclosure have the same meanings as those understood by those of ordinary skill in the art to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined as such herein.

[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0030] like Figures 1 to 4 As shown, the present disclosure provides an assembled locking nut disassembly tool, comprising: a plurality of cylinders 1 of different lengths; a force-applying assembly 2; a gear ring 3; wherein the force-applying assembly and the gear ring 3 can be selectively and detachably connected to the two ends of one of the cylinders 1, the cylinder 1 can transmit the torque of the force-applying assembly 2 to the gear ring 3, and the gear ring 3 can fit the locking nut.

[0031] Specifically, in the actual process of disassembling the locking nut, when the cylinder 1 is too short, the disassembly tool cannot be close to the locking nut inside the bearing box, and the fitting surface of the toothed ring 3 and the locking nut is unevenly stressed, which causes the locking nut to deform or break, and also reduces the service life of the disassembly tool; when the cylinder 1 is too long, the excess length of the disassembly tool beyond the bearing box will cause it to be easily unstable and damaged under the action of external force, increasing the risk of the operator. When the disassembly tool of the present disclosure is used to disassemble or lock the locking nuts at different depths inside the equipment, a cylinder 1 of a suitable length can be selected from a plurality of cylinders 1 of different lengths, and the force-applying component 2 and the toothed ring 3 are respectively installed at both ends of the cylinder 1, so that the force-applying component 2 extends to a suitable position outside the bearing box, which is convenient for operation. During operation, the staff applies a torsional torque to the force-applying component 2, and at the same time, the toothed ring 3 is close to the surface of the disassembled locking nut, and the cylinder 1 transmits the torsional torque applied by the staff to the toothed ring 3, and the toothed ring 3 drives the locking nut to twist to achieve the purpose of disassembly or locking.

[0032] like Figures 1 to 4 As shown, in some embodiments, threaded holes parallel to the central axis of the cylinder 1 along the length direction are provided on the top of one end of the cylinder 1 and the gear ring 3, and the gear ring 3 and the cylinder 1 are connected by bolts.

[0033] Specifically, the gear ring 3 is installed on the top of one end of the cylinder 1, and a plurality of threaded holes are distributed on the gear ring 3 around the central axis of the cylinder 1. Similarly, a plurality of corresponding threaded holes are distributed on the top of the cylinder 1 connected to one end of the gear ring 3. The cylinder 1 transmits the torsional torque to the gear ring 3 through bolts.

[0034] In other embodiments, in order to handle locking nuts of different diameters, threaded holes relative to the center axis direction are provided on the cylinder 1 and the gear ring 3. At this time, the larger gear ring 3 can be sleeved on the outside of the cylinder 1 or the smaller gear ring 3 can be sleeved on the inside of the cylinder 1, and the cylinder 1 and the gear ring 3 are connected by bolts.

[0035] In other embodiments, the gear ring 3 and the cylinder body 1 may be detachably connected by means of a snap connection or the like, which can also achieve the purpose of replacing accessories to adapt to different working conditions.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the gear ring 3 is provided with a plurality of teeth 301 distributed circumferentially around the central axis. In order to distribute the torsional moment on the contact surface between the gear ring 3 and the locking nut and avoid stress concentration, the contact surface between the gear ring 3 and the locking nut is provided with a plurality of teeth 301, and each tooth 301 can bite the locking nut. Figure 1 As shown, in some embodiments, eight teeth 301 are evenly distributed on the surface where the gear ring 3 and the locking nut fit together, which can evenly distribute the torsional torque on the fitting surface of the gear ring 3 and the locking nut, making the force more dispersed and further enhancing the stability of the connection.

[0037] like Figures 1 to 4 As shown, in some embodiments, the force applying assembly 2 further includes at least one force applying handle 202 detachably connected to the barrel 1. The force applying handle 202 can be directly mounted on the barrel 1, for example, directly inserted into the barrel 1, or arranged on the barrel 1 through other components.

[0038] Specifically, the staff can use the force applying handle 202 disposed outside the flange ring 201 to apply a torsional torque to the locking nut more effortlessly, thereby improving the efficiency of removing the locking nut.

[0039] like Figures 1 to 4 As shown, in some embodiments, the force-applying assembly 2 includes a flange ring 201 that can be sleeved on the cylinder 1 , the force-applying assembly 2 and the cylinder 1 are connected by bolts, and the force-applying handle 202 is disposed outside the flange ring 201 .

[0040] Specifically, the cylinder 1 is provided with circumferentially distributed threaded holes on the side wall connected to one end of the force-applying component 2, and the flange ring 201 is provided with corresponding threaded holes, so that the force-applying component 2 and the cylinder 1 can be bolted together. In order to facilitate the staff to apply external force, the force-applying component 2 is sleeved on the outside of the cylinder 1 with the help of the flange ring 201, and the force-applying handle 202 is arranged on the outside of the flange ring 201, which effectively increases the arm length from the external force application point to the central axis of the cylinder 1, so that the staff can save more effort and further improve the disassembly efficiency. In other embodiments, the force-applying component 2 can also be detachably connected to the cylinder 1 by means of snap-on connection, etc., which can also achieve the purpose of replacing accessories to adapt to different working conditions.

[0041] like Figure 4 As shown, in some embodiments, the force applying handle 202 is rotatably hinged to the flange ring 201. The force applying handle 202 is rotatably hinged to the flange ring 201 through a hinge axis, and the extension direction of the hinge axis is the tangential direction of the flange ring 201. In the use state, the force applying handle 202 rotates around the hinge axis to the radial direction of the flange ring 201, and the force applying handle 202 is perpendicular to the cylinder 1. Under the action of external force, the length of the force arm is the largest. At this time, the force applying assembly 2 is in the most labor-saving state; in the unused state, the force applying handle 202 can be rotated around the hinge axis to any position between the radial and axial directions of the flange ring 201. When a plurality of force applying handles 202 are provided on the force applying assembly 2, during the process of removing the locking nut, due to the limited space in the bearing box or the obstruction of surrounding equipment, one of the force applying handles 202 is rotated to the use state within the limited working space, and at the same time, the other force applying handles 202 are rotated to the unused state to avoid blocking the rotation of the force applying assembly 2 (such as Figure 4 As shown, the other force applying handles 202 can be rotated to a position along the axial direction of the flange ring 201 to avoid collision). When the force applying handle 202 within the working space is rotated to the edge of the working space, at this time, since multiple force applying handles 202 are provided, the multiple force applying handles 202 can be operated in turn, ultimately achieving the purpose of removing the locking nut.

[0042] In other embodiments, a plurality of circumferentially distributed embedding grooves may be provided on the outside of the flange ring 201, and a single force applying handle 202 may be respectively fixed in the plurality of embedding grooves and drive the cylinder 1 to rotate, thereby improving the operating efficiency of the disassembly tooling in a limited working space.

[0043] like Figures 1 to 4 As shown, in some embodiments, the force applying assembly 2 includes three force applying handles 202, and the three force applying handles 202 are evenly distributed on the outside of the flange ring 201 along the circumferential direction, so that the staff can evenly and effectively apply torque to the locking nut, which is more convenient to use.

[0044] like Figure 2As shown, in some embodiments, the force applying handle 202 is provided with a force applying groove 203 which passes through in a direction parallel to the central axis of the cylinder body 1 .

[0045] Specifically, in order to facilitate the application of a greater torque, the force application groove 203 is located at the end of the force application handle 202 away from the barrel 1, and the staff embeds the torque wrench inside the force application groove 203. In order to meet the requirements that the torque wrench can be embedded inside the force application groove 203 and prevent slipping, the force application groove 203 can be a rectangular groove, a hexagonal groove, or an octagonal groove. During operation, the staff embeds the torque wrench inside the force application groove 203 to apply torque, which can complete the disassembly work more efficiently.

[0046] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, a sealing plate 204 is fixed to the force applying handle 202 , and the sealing plate 204 is used to seal the opening of the force applying groove 203 close to the gear ring 3 . The sealing plate 204 is provided with a fixing hole 205 parallel to the center axis direction.

[0047] Specifically, since the torque required to remove the locking nut is relatively large, in order to prevent the inner wall of the force application slot 203 from being deformed and damaged by the repeatedly applied torque, a sealing plate 204 is provided on the side of the force application slot 203 close to the gear ring 3, and the sealing plate 204 is fixed on the force application handle 202. The torque wrench is fixed to the sealing plate 204 by screwing or riveting using the fixing holes 205 on the sealing plate 204, so that the connection between the sealing plate 204 and the force application handle 202 can bear the torque, thereby reducing the torque borne by the inner wall of the force application slot 203. When the torque wrench and the force application handle 202 rotate relative to each other due to the repeatedly applied torque, the sealing plate 204 fixed on the force application handle 202 will be damaged and deformed before the inner wall of the force application slot 203. At this time, only the sealing plate 204 needs to be replaced, and the force application handle 202 does not need to be replaced, thereby saving the maintenance cost of the tooling.

[0048] In some embodiments, the sealing plate 204 is welded and fixed to the force-applying handle 202. When the sealing plate 204 rotates relative to the force-applying handle 202 under the action of the torque wrench, if only the solder between the sealing plate 204 and the force-applying handle 202 is damaged, the damaged position can be repaired by welding without replacing the sealing plate 204, thereby saving the maintenance cost of the tooling. In other embodiments, the sealing plate can also be fixed to the force-applying handle 202 by riveting, clamping, etc.
