Alternatively, as shown in fig. 1, the mounting structure 1 is an annular plate-like structure, and the inner hole of the annular plate-like structure is larger than the diameter of the bearing hole of the gear box for mounting the target bearing. When the whole supporting tool is installed on the outer wall of the box body of the gearbox, the annular plate-shaped structure and the bearing hole are concentrically arranged, and then the installing structure 1 is fixed on the outer wall of the box body by adopting a fastener. Specifically, as shown in fig. 1, a plurality of mounting holes 101 through which fasteners are inserted are provided along the circumferential direction of the annular plate-like structure. Of course, in other embodiments, the mounting structure 1 may also be other structures, such as a semi-circular or semi-annular plate-like structure.
The supporting shaft assembly 2 and the bottom supporting assembly 3 are matched to stably support the gear shaft when the target bearing is disassembled and assembled, so that the gear shaft can stably and precisely rotate. Specifically, as shown in fig. 1 and 2, the support shaft assembly 2 includes a support shaft 201 and a bearing seat 202, the bearing seat 202 is provided with a through hole along an axial direction, the support shaft 201 is located in the through hole, and one end of the support shaft 201 is connected with a gear shaft in the gear box, on which a target bearing is mounted.

Specifically, as shown in fig. 1 to 3, the bottom support assembly 3 includes a support plate 301 and at least two support bodies 302, one end of the support plate 301 is connected to the bottom of the mounting structure 1, and the connection manner is not limited, and may be a connection member, a welding or an integral molding. At least two supporting bodies 302 are disposed on the supporting plate 301 at intervals along the dismounting path of the target bearing, and each supporting body 302 is detachably connected between the supporting shaft assembly 2 and the bearing housing 202. In the present embodiment, the number of the supporting bodies 302 is two, and the two supporting bodies 302 are respectively disposed at two ends of the bearing seat 202, and for convenience of description, the supporting body 302 close to the mounting structure 1 is named as a first supporting body, and the supporting body 302 far from the mounting structure 1 is named as a second supporting body.
When the target bearing is detached from the gear shaft, the use method of the support tool comprises the following steps:
firstly, after a support shaft assembly 2 of a support tool is aligned with a target bearing of a gear box, a mounting structure 1 is connected with a box body of the gear box, and a support shaft 201 is connected with a gear shaft; then the first support body is detached from between the support plate 301 and the bearing seat 202 (at this time, the second support body is supported between the support plate 301 and the bearing seat 202), and the bearing is detached from the gear shaft by using a bearing detaching tool (such as a clamp or other mechanisms) and then pulled to the second support body; finally, the first support body is installed between the support plate 301 and the bearing seat 202 again, after the first support body is installed in place, the second support body is detached from the space between the support plate 301 and the bearing seat 202, and the bearing can be smoothly separated from the support tool at the moment, so that the detachment of the target bearing is completed.
The supporting tool can also be used for mounting a target bearing. When the target bearing is installed, the second support body needs to be detached from between the support plate 301 and the bearing seat 202 (at this time, the first support body is supported between the support plate 301 and the bearing seat 202), and the target bearing is moved to the first support body; then, the second support body is installed between the support plate 301 and the bearing seat 202 again, after the second support body is installed in place, the first support body is detached from the position between the support plate 301 and the bearing seat 202, and at the moment, the target bearing can be moved to a bearing hole of the gear box; and finally, the bearing can be mounted on the gear shaft by using the bearing mounting tool, so that the target bearing is mounted.
In the whole bearing dismounting or mounting process, as the support body 302 is always positioned between the support plate 301 and the bearing seat 202, the bearing seat 202 can be always stably supported, and further the gear shaft can be stably supported. When the gear shaft rotates accidentally, due to the existence of the supporting shaft 201 and the bearing seat 202, the rotation precision of the gear shaft is high, the stability is good, and therefore the gear inside the gear box and the bearing at the other end of the gear shaft cannot be damaged, and the safety of the gear box is guaranteed. In addition, the bearing is disassembled and assembled by the support tool, and the box body of the gear box does not need to be disassembled, so that the shutdown time and the maintenance and replacement time of the bearing can be effectively shortened, and the maintenance cost is favorably reduced.

Further optionally, a limiting shaft sleeve 204 is further disposed between the two support bearings 203, and the relative position of the two support bearings 203 is limited by the limiting shaft sleeve 204.
In order to facilitate the connection between the support shaft 201 and the gear shaft, a flange 2011 is arranged at one end of the support shaft 201, the size of the flange 2011 is larger than the shaft diameter of the support shaft 201, and the flange 2011 is connected with the gear shaft, so that the operation is facilitated. Specifically, as shown in fig. 1 and 2, a plurality of first coupling holes 2012 are provided along a circumferential direction of the flange 2011, and a plurality of second coupling holes (not shown) are provided at opposite positions of the gear shaft, and the support shaft 201 and the gear shaft are coupled by passing the first coupling members through the first coupling holes 2012 and the second coupling holes. Optionally, the first connecting hole 2012 and the second connecting hole are both threaded holes, and the first connecting member is a screw.
Further, in order to reduce the difficulty of detaching and mounting the supporting body 302 between the supporting plate 301 and the bearing housing 202, in the present embodiment, the rotating method employs a rotating detaching and rotating method. Specifically, as shown in fig. 1, the top surface of the supporting body 302 is set as a first arc-shaped surface, and the bottom surface of the supporting body 302 is set as a fourth arc-shaped surface. Correspondingly, the outer wall surface of the bearing housing 202 is set to be a second arc surface, and the surface of the support plate 301 abutting against the support body 302 is set to be a third arc surface. The first arc surface abuts the second arc surface, the third arc surface abuts the fourth arc surface, and each support 302 is configured to be rotatable around the bearing housing 202 to have a first state located between the support plate 301 and the bearing housing 202 to support the bearing housing 202 and a second state not located between the support plate 301 and the bearing housing 202 to avoid a disassembly and assembly path of the target bearing.
Optionally, the first arc surface, the second arc surface, the third arc surface, and the fourth arc surface are concentrically disposed to further improve the smoothness of the rotation of the support 302. Of course, in other embodiments, the first arc surface, the second arc surface, the third arc surface, and the fourth arc surface may also be set to be planar structures, but compared with the planar structures, the arc surface structures are more favorable for the detachment and installation of the support body 302, and therefore, in this embodiment, the arc surface structures are preferably adopted.
Further, in order to improve the stability of the supporting body 302 in the first state and avoid the accidental rotation, a second connecting member is further disposed between the supporting plate 301 and the supporting body 302, and the second connecting member is used to detachably connect the supporting plate 301 and the supporting body 302. Specifically, the support plate 301 is provided with a third connection hole 3011, the bottom of the support body 302 is provided with a fourth connection hole 3021, and the second connector is disposed through the third connection hole 3011 and the fourth connection hole 3021.
