[0027] It should be noted that the bracket 1 of the present embodiment is assembled on the housing of the gear box by two bolts and two connecting pins 33, so that the tooling for rotating the connecting shaft of the driving gear box is detachably connected to the housing. When the connecting shaft needs to be rotated to clean the gear box or to make the gear box run without load, the bracket 1 of the tooling for rotating the connecting shaft of the driving gear box is installed on the housing, and after cleaning or running without load, the tooling for rotating the connecting shaft of the driving gear box is removed from the housing.

[0028] Furthermore, when the gearbox is a rolling bearing gearbox, if the rolling bearing gearbox cannot operate normally, the tooling for driving the connecting shaft of the gearbox to rotate in this embodiment can also drive the connecting shaft of the gearbox to rotate, thereby achieving normal rotation of the gearbox.

[0029] The tooling for driving the connecting shaft of the gearbox to rotate provided in this embodiment, when the power component drives the rotating wheel 4 to drive the coupling 3 and the connecting shaft to rotate, the bracket 1 and the bearing 2 can bear the fixed-direction force generated by the power component on the rotating wheel 4, so that the wear of the connecting shaft on the bearing is reduced, the probability of repairing the gearbox due to bearing damage is reduced, and the maintenance cost of the gearbox is reduced.

[0030] like Figure 1 As shown, the coupling 3 of this embodiment includes a flange 31, a flange shaft 32, a connecting pin 33 and two first baffles 34. One end of the flange 31 is fixedly arranged on the connecting shaft, one end of the flange shaft 32 is fixedly arranged on the other end of the flange 31, a rotating wheel 4 is arranged on the other end of the flange shaft 32, and a bearing 2 is sleeved on the middle part of the flange shaft 32. One of the first baffles 34 is fixedly arranged on the flange 31, and the other first baffle 34 is fixedly arranged on the flange shaft 32. The connecting pin 33 is arranged through the flange 31 and the flange shaft 32 and is sandwiched between the two first baffles 34.

[0031] Specifically, the connecting pin 33 of this embodiment is a nylon pin, and the number of the connecting pins 33 is at least two, and at least two connecting pins 33 are distributed along the circumference of the flange 31. The first baffle 34 fixed on the flange 31 is fixed to the end surface of the flange 31 by means of screws or other locking members, and the other first baffle 34 fixed on the flange shaft 32 is fixed to the end surface of the flange shaft 32 by means of screws or other locking members, and the two first baffles 34 are respectively abutted against the two ends of the connecting pin 33 to prevent the connecting pin 33 from jumping out along the axial direction of the coupling 3, so as to ensure that the flange 31 and the flange shaft 32 are firmly connected together. In other embodiments, the connecting pin 33 can also be a connecting pin 33 made of other materials, which is selected according to actual needs.

[0032] Furthermore, a gap is set between the flange 31 and the connecting shaft in this embodiment, a first positioning member (not shown in the figure) is provided on the flange 31, the length of the first positioning member screwed into the flange 31 is adjustable, and a first abutment member (not shown in the figure) is clamped between the flange 31 and the connecting shaft, and the locking end of the first positioning member abuts against the first abutment member to enable the flange 31 to rotate synchronously with the connecting shaft.

[0033] The first positioning member of the present embodiment is a set screw, the first abutment member is a copper washer, the connecting shaft is a steel connecting shaft, and the length of the first positioning member screwed into the flange 31 is adjustable, so that the first positioning member abuts against the first abutment member and the first abutment member is pressed against the connecting shaft by the first positioning member. Since the copper washer is softer, the damage to the connecting shaft by the first abutment member is reduced, that is, the connecting shaft and the flange 31 are connected by the first positioning member and the first abutment member, which ensures that the flange 31 and the connecting shaft can rotate synchronously. This installation method ensures the synchronous rotation of the flange 31 and the connecting shaft without changing the structure of the connecting shaft. In other embodiments, the first positioning member and the first abutment member are not limited to the limitations of the present embodiment, and the first positioning member can also be a screw, a bolt, etc., and the first abutment member can also be made of other materials with softer hardness, which are selected according to actual needs.

[0034] The rotating wheel 4 of this embodiment is interference fitted on the flange shaft 32, and a second positioning piece (not shown in the figure) is provided on the rotating wheel 4. The length of the second positioning piece screwed into the rotating wheel 4 is adjustable, and a second abutment piece (not shown in the figure) is clamped between the rotating wheel 4 and the flange shaft 32. The locking end of the second positioning piece abuts against the second abutment piece to ensure that the rotating wheel 4 and the flange shaft 32 rotate synchronously.

[0035] The second positioning member of the present embodiment is a set screw, the second abutting member is a copper washer, the flange shaft 32 is a stainless steel flange shaft 32, and the length of the second positioning member screwed into the rotating wheel 4 is adjustable, so that the second positioning member abuts against the second abutting member and the second abutting member is pressed against the flange shaft 32 by the second positioning member. Since the copper washer is softer, the damage to the flange shaft 32 by the second abutting member is reduced, that is, the flange shaft 32 and the rotating wheel 4 are connected by the second positioning member and the second abutting member, which ensures that the flange shaft 32 and the rotating wheel 4 can rotate synchronously. This installation method ensures the synchronous rotation of the flange shaft 32 and the rotating wheel 4 without changing the structure of the flange shaft 32. In other embodiments, the second positioning member and the second abutting member are not limited to the limitation of the present embodiment, and the second positioning member can also be a screw, a bolt, etc., and the second abutting member can also be made of other materials with softer hardness, which are selected according to actual needs.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, the tooling for rotating the connecting shaft of the driving gear box in this embodiment also includes a pressure plate 5 and a second baffle 6. The pressure plate 5 is fixedly arranged at the end of the flange shaft 32 away from the flange disk 31. The rotating wheel 4 is clamped between the pressure plate 5 and the bearing 2. The second baffle 6 is fixedly arranged on the bracket 1 and the second baffle 6 is spaced apart from the first baffle 34. The second baffle 6 abuts against the outer ring of the bearing 2. The pressure plate 5 and the second baffle 6 can limit the axial movement of the rotating wheel 4 to prevent the rotating wheel 4 from moving along its own axial direction.

[0037] Specifically, Figure 1 and Figure 2 As shown, the tooling for driving the connecting shaft of the gear box of this embodiment to rotate further includes a first distance ring 71 and a second distance ring 72, the first distance ring 71 is loosely mounted on the flange shaft 32, the first distance ring 71 is sleeved on the coupling 3, and the first distance ring 71 is sandwiched between the inner ring of the bearing 2 and the rotating wheel 4. There are two bearings 2 in this embodiment, both of which are rolling bearings, and the bearings 2 are lubricated with grease, the second distance ring 72 is loosely mounted on the flange shaft 32, the second distance ring 72 is sleeved on the coupling 3, and the second distance ring 72 is sandwiched between the inner rings of the two bearings 2.

[0038] Specifically, the rotating wheel 4, the first distance ring 71, a bearing 2, the second distance ring 72 and another bearing 2 of this embodiment are sandwiched between the pressure plate 5 and the second baffle 6 in sequence, that is, the pressure plate 5 and the second baffle 6 play an axial limiting role on the bearing 2, the second distance ring 72, another bearing 2, the first distance ring 71 and the rotating wheel 4. The pressure plate 5 and the second baffle 6 press the rotating wheel 4, the first distance ring 71, a bearing 2, the second distance ring 72 and another bearing 2 in sequence to prevent the rotating wheel 4 from generating axial movement relative to the flange shaft 32, thereby ensuring that the torque output by the power assembly is transmitted to the connecting shaft through the coupling 3.

[0039] like Figure 1 and Figure 2 As shown, a through hole 3201 is provided at the center of the flange shaft 32 of the present embodiment, that is, the flange shaft 32 is a hollow structure, and a plurality of heat dissipation holes 3202 are provided on the flange shaft 32, each heat dissipation hole 3202 is connected to the through hole 3201, and the heat dissipation holes 3202 are located between the first baffle plate 34 and the second baffle plate 6. The heat dissipation holes 3202 can dissipate heat for the flange shaft 32, thereby reducing the temperature of the flange shaft 32 with a higher temperature, and ultimately improving the actual operating condition of the bearing 2.

[0040] When the tooling for rotating the connecting shaft of the driving gear box of this embodiment is installed on the connecting shaft of the gear box, firstly, the various parts of the tooling for rotating the connecting shaft of the driving gear box are assembled together to form an integral structure, and then the bracket 1 of the tooling for rotating the connecting shaft of the driving gear box is fixedly installed on the housing of the gear box, and then the flange 31 is fixed on the connecting shaft using the first positioning member and the first abutting member. It can be seen that the tooling for rotating the connecting shaft of the driving gear box of this embodiment is easy to install and simple to operate, and the installation time is greatly shortened compared with the prior art.

[0041] In other embodiments, the flange 31 can be first installed on the connecting shaft through the first positioning member and the first abutment member, and then the remaining structures of the tooling for rotating the connecting shaft of the driving gear box are assembled together and fixedly installed on the housing of the gear box. Finally, the flange 31 and the flange shaft 32 are fixedly connected by a connecting pin 33, and two first baffles 34 are used to axially limit the connecting pin 33. The installation method of installing the tooling for rotating the connecting shaft of the driving gear box on the gear box can be adjusted according to actual needs and is not limited to this limitation of the present embodiment.

[0042] The tooling structure for rotating the connecting shaft of the driving gear box in this embodiment is simple, the production cost is low, and the applicability is strong. The bracket 1 and the bearing 2 can both bear the fixed-direction force generated by the power component on the rotating wheel 4, so that the wear of the connecting shaft on the bearing is reduced, and the probability of repairing the gear box due to bearing damage is reduced.
