[0054] A roadheader is a sophisticated piece of equipment integrating multiple technologies such as machinery, electricity, hydraulics, optics, and remote sensing. It can complete functions such as drilling, mucking, and lining in one go and is widely used in tunnel projects such as municipal, mountain, and undersea tunnels. The main drive system is the key core component of the roadheader and is the power source of the roadheader. During the working process of the roadheader, it provides the rotary torque for the cutter head of the roadheader and bears complex loads and overturning moments, etc. Since the main drive system directly faces working conditions such as complex construction situations and variable loads, the safety and reliability of the main drive system are the key to ensuring the normal and efficient construction of the roadheader.

[0055] Reference Figure 1 , the main drive system may include a gearbox 10, a gear 20, and an internal gear ring 30. The gearbox 10 is usually connected to a driving device, such as an electric motor, etc. The gear 20 can be installed inside the gearbox 10 and serves to transmit the rotary torque. The internal gear ring 30 meshes with the gear 20, and the internal gear ring 30 is also connected to the cutter head. The driving device can drive the gear 20 to rotate through the gearbox 10, thereby driving the internal gear ring 30 to rotate, and further driving the cutter head to rotate for operations such as excavation and rock breaking. The internal gear ring 30 is used to bear working conditions such as high impact, large thrust, large eccentric load, and large torque generated during the excavation and rock breaking of the cutter head, and its performance and lifespan play a key role in the working and lifespan of the roadheader.

[0056] The gearbox 10 has a positioning surface 110, and the positioning surface 110 is used to position the gearbox 10 during the assembly process of the gear 20 and the internal gear ring 30. The gearbox 10 is also provided with an installation opening 120, and a part of the gear 20 protrudes from the installation opening 120 to mesh with the internal gear ring 30. Exemplarily, the number of gears 20 can be multiple, and the multiple gears 20 can be arranged at intervals in the circumferential direction of the gearbox 10, and the multiple gears 20 are all meshed with the internal gear ring 30. The driving device can drive the multiple gears 20 to rotate through the gearbox 10, and the multiple gears 20 drive the internal gear ring 30 to rotate simultaneously. The assembly accuracy of the gear 20 and the internal gear ring 30 directly affects the meshing situation of the gear 20 and the internal gear ring 30, thereby affecting the power transmission efficiency and load-bearing capacity of the main drive system, and further affecting the performance and service life of the roadheader.

[0057] In the related art, when assembling the gear 20 and the internal gear ring 30 in the main drive system, the following steps are usually included:

[0058] (1) Place the internal gear ring 30 horizontally;

[0059] (2) Assemble the gear 20 into the gearbox 10;

[0060] (3) Use a crane to lift the gearbox 10 to an appropriate position above the internal gear ring 30;

[0061] (4) Take multiple measurement points along the positioning surface 110 of the transmission 10, use a straightedge to measure the distances between the multiple measurement points and the upper end surface of the internal gear ring 30, and continuously adjust the chain block of the overhead crane to adjust the attitude of the transmission 10 so that the distances between the multiple measurement points and the upper end surface of the internal gear ring 30 are all equal, so as to make the transmission 10 in a horizontal position;

[0062] (5) Control the overhead crane to lower the transmission 10 to an appropriate position, use tools such as a flashlight for illumination, and insert an endoscope camera into the internal gear ring 30 to observe the tooth condition of the internal gear ring 30;

[0063] (6) The staff inserts the arm between the transmission 10 and the internal gear ring 30 and rotates the gear 20 to align the teeth of the gear 20 with the tooth grooves of the internal gear ring 30;

[0064] (7) Control the overhead crane to lower the transmission 10 so that the gear 20 meshes with the internal gear ring 30.

[0065] However, when assembling the gear 20 and the internal gear ring 30 in the main drive system in the related art, the staff needs to insert the arm between the transmission 10 and the internal gear ring 30 to adjust the gear 20, which has a high risk of work injury, is time-consuming and laborious, and has low assembly and adjustment efficiency.

[0066] In view of this, the embodiment of the present application provides a main drive assembly tooling. The main drive assembly tooling includes a first assembly and adjustment member, a second assembly and adjustment member, and an adjustment rod. The first assembly and adjustment member has a connecting tooth that can be inserted into the tooth groove of the internal gear ring. The second assembly and adjustment member has a connecting groove that can be sleeved on the tooth of the gear, and an adjustment hole for the adjustment rod to pass through. During the assembly process, the second assembly and adjustment member abuts against the first assembly and adjustment member, and the staff can apply a rotational force to the second assembly and adjustment member through the adjustment rod inserted into the adjustment hole, so that the second assembly and adjustment member and the gear rotate relative to the transmission until the teeth of the gear correspond to the tooth grooves of the internal gear ring. With such a setting, it is possible to avoid the staff from putting their hands between the internal gear ring and the transmission to adjust the gear, thereby reducing the risk of work injury, reducing manpower and time, and improving the efficiency of assembling the gear and the internal gear ring.

[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts shall fall within the scope of protection of the present application.

[0068] The embodiment of the present application provides a main drive assembly tooling for assembling the gear 20 and the internal gear ring 30 installed in the transmission 10 in the main drive system of a roadheader. Refer to Figure 2, Figure 3 , Figure 4 , Figure 5 and Figure 6 , the main drive assembly tooling 40 includes a first adjustment part 410, a second adjustment part 420 and an adjustment rod 430. The first adjustment part 410 includes an adjustment plate 411 and a connecting tooth 412, and the connecting tooth 412 is connected to the surface of the adjustment plate 411. The second adjustment part 420 is provided with a connecting groove 421, and the second adjustment part 420 is further provided with an adjustment hole 422. The adjustment rod 430 can be inserted into the adjustment hole 422.

[0069] When assembling the adjustment gear 20 and the internal gear ring 30, the connecting tooth 412 is inserted into the tooth groove of the internal gear ring 30, the connecting groove 421 is sleeved on the tooth of the gear 20, the second adjustment part 420 abuts against the surface of the first adjustment part 410 facing away from the connecting tooth 412, and the adjustment rod 430 is inserted into the adjustment hole 422, so that the second adjustment part 420 and the gear 20 rotate relative to the gearbox 10 until the teeth of the gear 20 correspond to the tooth grooves of the internal gear ring 30. With such a setting, it can prevent the staff from putting their hands between the internal gear ring 30 and the gearbox 10 to adjust the gear 20, thereby reducing the risk of work-related injuries, saving manpower and time, and improving the efficiency of assembling the gear 20 and the internal gear ring 30.

[0070] In addition, when assembling the gear 20 and the internal gear ring 30 in the main drive system in the related art, in step (6), if the staff manually adjusts the gear 20, it is very easy to generate errors, resulting in the teeth of the gear 20 not corresponding to the tooth grooves of the internal gear ring 30. In step (7), when the gearbox 10 drops, the teeth of the gear 20 and the teeth of the internal gear ring 30 interfere with each other. At this time, tools such as copper bars are needed to strike the gear 20 to make the gear 20 rotate, so that the teeth of the gear 20 are opposite to the tooth grooves of the internal gear ring 30, and then the gear 20 can be meshed with the internal gear ring 30. However, when striking the gear 20, it is easy to damage the teeth of the gear 20 and the internal gear ring 30, reducing the assembly accuracy and transmission accuracy between the gear 20 and the internal gear ring 30.

[0071] In the embodiment of the present application, when the teeth of the gear 20 and the teeth of the internal gear ring 30 interfere with each other, the adjustment rod 430 can be rotated, and the gear 20 is rotated through the second adjustment part 420, so that the teeth of the gear 20 are opposite to the tooth grooves of the internal gear ring 30, avoiding striking the gear 20, thereby avoiding damaging the teeth of the gear 20 and the internal gear ring 30, and ensuring the assembly accuracy and transmission accuracy between the gear 20 and the internal gear ring 30.

[0072] Exemplarily, referring to Figure 2 and Figure 3 , the first adjustment part 410 may include an adjustment plate 411 and a connecting tooth 412, and the connecting tooth 412 is connected to the surface of the adjustment plate 411. For exampleFigure 3 As shown, the connecting teeth 412 are connected to the lower surface of the adjustment plate 411. The lower surface of the adjustment plate 411 can be adapted to the end face of the internal gear ring 30. For example, the lower surface of the adjustment plate 411 can be the first plane 414 adapted to the end face of the internal gear ring 30. With such a setting, the contact area between the adjustment plate 411 and the internal gear ring 30 can be increased, thereby improving the stability of the adjustment plate 411. During the assembly process of the gear 20 and the internal gear ring 30, the first adjustment part 410 can be prevented from shaking or tilting, and thus the assembly accuracy of the gear 20 and the internal gear ring 30 can be guaranteed. It can be understood that the lower surface of the adjustment plate 411 can also be a surface of other surface types adapted to the end face of the internal gear ring 30, which will not be elaborated in this embodiment of the present application. The upper surface of the adjustment plate 411 can be the second plane 415. During the assembly process of the gear 20 and the internal gear ring 30, the second plane 415 can be in contact with the second adjustment part 420, and the second adjustment part 420 can be enabled to rotate on the second plane 415.

[0073] The connecting teeth 412 can be inserted into the tooth grooves of the internal gear ring 30 to mesh with the teeth of the internal gear ring 30. Exemplarily, the module of the connecting teeth 412 is the same as that of the internal gear ring 30. In some possible implementation manners, the number of the connecting teeth 412 can be multiple, and the multiple connecting teeth 412 can be respectively inserted into multiple adjacent tooth grooves of the internal gear ring 30 to increase the contact area between the first adjustment part 410 and the internal gear ring 30, improve the stability of the first adjustment part 410, and thus prevent the first adjustment part 410 from shaking or tilting during the assembly process of the gear 20 and the internal gear ring 30, and further guarantee the assembly accuracy of the gear 20 and the internal gear ring 30.

[0074] Reference Figure 2 And Figure 4 As shown in, the second adjustment part 420 is provided with a connecting groove 421, and the connecting groove 421 can be sleeved on the teeth of the gear 20. Exemplarily, two adjustment teeth 426 can be provided on the second adjustment part 420, and the connecting groove 421 is formed between the two adjustment teeth 426. In some possible implementation manners, the module of the adjustment teeth 426 can be the same as that of the gear 20, so that the adjustment teeth 426 can mesh with the teeth of the gear 20, improve the connection strength between the second adjustment part 420 and the gear 20, and prevent the second adjustment part 420 from shaking or tilting during the adjustment process of the gear 20 and the internal gear ring 30, thereby guaranteeing the assembly accuracy of the gear 20 and the internal gear ring 30.

[0075] Optionally, the shape of the connecting groove 421 can also be adapted to the shape of the teeth of the gear 20, so that the connecting groove 421 and the gear 20 have the largest contact area, thereby further increasing the connection strength between the second adjustment part 420 and the gear 20.

[0076] ​Exemplarily, the number of the connecting grooves 421 can be multiple, and the multiple connecting grooves 421 can be respectively sleeved on multiple teeth of the gear 20, so as to increase the contact area between the second adjustment part 420 and the gear 20, improve the stability of the second adjustment part 420, and thus avoid the shaking or tilting of the second adjustment part 420 during the assembly process of the gear 20 and the internal gear ring 30, and further ensure the assembly accuracy of the gear 20 and the internal gear ring 30.

[0077] The second adjustment part 420 is further provided with an adjustment hole 422. The adjustment rod 430 can be inserted into the adjustment hole 422. Exemplarily, the number of the adjustment holes 422 can be multiple, and the multiple adjustment holes 422 can be arranged at different positions of the second adjustment part 420. During the assembly process of the gear 20 and the internal gear ring 30, the staff can select the adjustment hole 422 suitable for inserting the adjustment rod 430, so as to improve the convenience when rotating the gear 20.

[0078] Exemplarily, referring to Figures 2 to 4 , the adjustment plate 411 can be provided with a first alignment groove 413. The second adjustment part 420 can be provided with a second alignment groove 423. When the teeth of the gear 20 and the tooth grooves of the internal gear ring 30 correspond to each other, the second alignment groove 423 is aligned with the first alignment groove 413. During the assembly process of the gear 20 and the internal gear ring 30, by aligning the second alignment groove 423 with the first alignment groove 413, the teeth of the gear 20 and the tooth grooves of the internal gear ring 30 can be made to correspond to each other, so as to improve the corresponding accuracy between the teeth of the gear 20 and the tooth grooves of the internal gear ring 30, and further improve the assembly accuracy of the gear 20 and the internal gear ring 30.

[0079] Exemplarily, the center line of the first alignment groove 413 can be aligned with the center line of the connecting tooth 412. The center line of the second alignment groove 423 can be aligned with the center line of the connecting groove 421. With such a setting, when manufacturing the first alignment groove 413 and the second alignment groove 423, the difficulty of determining the positions of the first alignment groove 413 and the second alignment groove 423 can be reduced. It can be understood that the first alignment groove 413 can be located at other positions of the first adjustment part 410, and the second alignment groove 423 can be located at other positions of the second adjustment part 420, as long as the second alignment groove 423 is aligned with the first alignment groove 413 when the teeth of the gear 20 and the tooth grooves of the internal gear ring 30 correspond to each other, and the embodiments of the present application will not elaborate on this anymore.

[0080] Exemplarily, referring to Figure 2 、 Figure 4 and Figure 6, the top surface of the second adjustment part 420 facing away from the adjustment plate 411 can be the third plane 424, and the third plane 424 is used to abut against the positioning surface 110 of the transmission 10. During the assembly process of the gear 20 and the internal gear ring 30, it is possible to determine whether the transmission 10 is in a horizontal position by judging whether the positioning surface 110 of the transmission 10 abuts against the third plane 424 of the second adjustment part 420. If the positioning surface 110 of the transmission 10 abuts against the third plane 424 of the second adjustment part 420, the transmission 10 is in a horizontal position. If the positioning surface 110 of the transmission 10 does not abut against the third plane 424 of the second adjustment part 420, the transmission 10 is not in a horizontal position, and the attitude of the transmission 10 is adjusted until the positioning surface 110 of the transmission 10 abuts against the third plane 424 of the second adjustment part 420, so that the transmission 10 is in a horizontal position.

[0081] Regarding step (4) in the related art, since the volume of the transmission 10 is usually large, taking the main drive system with a diameter of 8.6 m as an example, the circumference of the transmission 10 is about 27 m. During the process of adjusting the transmission 10 to a horizontal position, the staff needs to walk back and forth around the transmission 10 when selecting the measurement points and adjusting the chain hoist, which takes a long time and is cumbersome to operate, time-consuming and laborious, resulting in low assembly efficiency of the main drive system. Compared with the related art that judges whether the transmission 10 is in a horizontal position by measuring the distances between multiple measurement points and the upper end surface of the internal gear ring 30 with a straight ruler, the embodiment of the present application does not need to use a straight ruler for measurement, simplifies the operation steps for detecting the position of the transmission 10, reduces the detection difficulty, and improves the assembly efficiency of the main drive system.

[0082] The lower surface of the second adjustment part 420 can be the fourth plane 425. The fourth plane 425 can abut against the second plane 415 of the adjustment plate 411, so that the second adjustment part 420 can rotate on the fourth plane 425, improving the smoothness of the second adjustment part 420 during rotation.

[0083] Exemplarily, referring to Figure 6 , along the axial direction of the gear 20, there is a first thickness H1 between the end surface of the gear 20 facing the internal gear ring 30 and the positioning surface of the transmission 10. The second adjustment part 420 and the adjustment plate 411 have a second thickness H2, and the second thickness H2 is greater than the first thickness H1. Such a setting is to avoid interference between other parts of the transmission 10 and the internal gear ring 30 when the positioning surface 110 of the transmission 10 abuts against the third plane 424.

[0084] Exemplarily, the number of the first adjustment members 410 may be greater than or equal to the number of the second adjustment members 420. During the assembly process of the gear 20 and the internal gear ring 30, when adjusting the gear 20, the second adjustment members 420 can be reused. That is to say, after adjusting a gear 20 with a second adjustment member 420, the second adjustment member 420 can be detached from the gear 20, and then the second adjustment member 420 can be sleeved on another gear 20. With such a setting, the number of the second adjustment members 420 can be reduced, and the structure of the main drive assembly tooling can be simplified.

[0085] Exemplarily, the number of the second adjustment members 420 may be greater than or equal to three. When detecting and adjusting the position of the transmission 10 through the third plane 424 of the second adjustment member 420, three or more second adjustment members 420 can improve the accuracy of detecting and adjusting the position of the transmission 10, thereby improving the position accuracy of the transmission 10 and the gear 20, and further ensuring the assembly accuracy of the gear 20 and the internal gear ring 30.

[0086] Reference Figure 2 and Figure 5 , the adjusting rod 430 may be in a rod shape for easy gripping by the staff. It can be understood that the adjusting rod 430 may also be tools such as a crowbar or a wrench, as long as it can be inserted into the adjusting hole 422 to rotate the second adjustment member 420, which will not be elaborated in this embodiment of the present application.

[0087] Exemplarily, the materials of the first adjustment member 410, the second adjustment member 420, and the adjusting rod 430 may be light, flexible, and wear-resistant materials. Optionally, the materials of the first adjustment member 410, the second adjustment member 420, and the adjusting rod 430 may be polymer materials, such as polytetrafluoroethylene, polyether ether ketone, or nylon. Optionally, the materials of the first adjustment member 410, the second adjustment member 420, and the adjusting rod 430 may also be metal materials, such as steel or brass. Optionally, the materials of the first adjustment member 410, the second adjustment member 420, and the adjusting rod 430 may also be other materials, such as wood.

[0088] Reference Figure 7 , a second aspect of the embodiment of the present application provides a main drive assembly method, using the main drive assembly tooling 40 provided in the first aspect of the embodiment of the present application. The main drive assembly method includes:

[0089] S1. Provide an internally toothed ring placed horizontally.

[0090] Exemplarily, the internally toothed ring 30 can be placed horizontally on the ground or an assembly platform. The axis of the internally toothed ring 30 is arranged in the vertical direction.

[0092] Exemplarily, the gear 20 can be installed inside the transmission 10. The number of gears 20 can be multiple. Part of the gears 20 can be exposed through the installation opening 120 of the transmission 10 for assembly with the internal gear ring 30.

[0093] S3. Lift the transmission to a first preset height above the internal gear ring.

[0094] Lifting devices such as overhead cranes can be used to lift the transmission 10 and the gear 20 to a first preset height above the internal gear ring 30, so as to facilitate the installation of the first adjustment part 410 and the second adjustment part 420 between the internal gear ring 30 and the gear 20. Exemplarily, when the transmission 10 is at the first preset height, the distance between the end face of the internal gear ring 30 and the positioning surface 110 of the transmission 10 can be made greater than the height of any one of the first adjustment part 410 and the second adjustment part 420, so as to facilitate the installation of the first adjustment part 410 and the second adjustment part 420 on the internal gear ring 30 and the gear 20 during the subsequent assembly process.

[0095] S4. Insert the connecting teeth of the first adjustment part into the tooth grooves of the internal gear ring.

[0096] Then, insert the connecting teeth 412 of the first adjustment part 410 into the tooth grooves of the internal gear ring 30 to connect the first adjustment part 410 with the internal gear ring 30. Exemplarily, the connecting teeth 412 can be inserted into the tooth grooves of the internal gear ring 30 directly below the gear 20 to avoid the need to horizontally rotate the transmission 10 subsequently, simplifying the steps of assembling the gear 20 and the internal gear ring 30. Exemplarily, the number of the first adjustment parts 410 can be equal to the number of the gears 20.

[0097] Exemplarily, when inserting the connecting teeth 412 of the first adjustment part 410 into the tooth grooves of the internal gear ring 30, the first plane 414 of the adjustment plate 411 can be made to abut against the end face of the internal gear ring 30 to improve the stability of the first adjustment part 410.

[0098] S5. Sleeve the connecting groove of the second adjustment part onto the gear teeth and place the second adjustment part on the adjustment plate of the first adjustment part.

[0099] Exemplarily, the connecting groove 421 of the second adjustment part 420 can be first sleeved onto the gear teeth of the gear 20, and then the second adjustment part 420 can be placed on the adjustment plate 411. For example, the position of the second adjustment part 420 can be adjusted by adjusting the length of the connection between the connecting groove 421 and the gear teeth of the gear 20, so that the fourth plane 425 of the second adjustment part 420 abuts against the second plane 415 of the adjustment plate 411.

[0100] Exemplarily, after the connection groove 421 of the second adjustment part 420 is sleeved on the tooth of the gear 20 and the second adjustment part 420 is placed on the adjustment plate 411, the transmission 10 can be lowered and the attitude of the transmission 10 can be adjusted so that the positioning surface of the transmission 10 abuts against the third plane 424 of the second adjustment part 420, thereby adjusting the transmission 10 to a horizontal position. If the positioning surface 110 of the transmission 10 does not abut against the third plane 424 of the second adjustment part 420, the transmission 10 is not in a horizontal position, and the attitude of the transmission 10 can be adjusted by the chain block of the overhead crane until the positioning surface 110 of the transmission 10 abuts against the third plane 424 of the second adjustment part 420, so that the transmission 10 is in a horizontal position.

[0101] Then, the transmission 10 is lifted to have a gap between the positioning surface 110 of the transmission 10 and the third plane 424 of the second adjustment part 420, so as to avoid that in the subsequent assembly process, the gear 20 cannot be rotated by the second adjustment part 420 due to the contact between the second adjustment part 420 and the positioning surface 110 of the transmission 10. Exemplarily, the gap between the positioning surface 110 of the transmission 10 and the third plane 424 of the second adjustment part 420 can be 20 - 50 cm.

[0102] S6. Insert the adjustment rod into the adjustment hole of the second adjustment part, and apply a rotational force to the second adjustment part through the adjustment rod to rotate the second adjustment part and the gear relative to the transmission until the teeth of the gear correspond to the tooth grooves of the internal gear ring.

[0103] Exemplarily, before the adjustment rod 430 is inserted into the adjustment hole 422 of the second adjustment part 420, along the axial direction of the gear 20, the length of the connection groove 421 fitting with the tooth of the gear 20 can be greater than or equal to one - quarter of the total length of the tooth of the gear 20, so as to ensure that there is sufficient contact area between the second adjustment part 420 and the gear 20, so that the second adjustment part 420 can drive the gear 20 to rotate and improve the assembly efficiency.

[0104] Then, the adjustment rod 430 is inserted into the adjustment hole 422 of the second adjustment part 420. The staff can apply a rotational force to the second adjustment part 420 through the adjustment rod 430 to rotate the second adjustment part 420 and the gear 20 relative to the transmission 10 until the teeth of the gear 20 correspond to the tooth grooves of the internal gear ring 30.

[0105] Exemplarily, when rotating the second adjustment part 420 and the gear 20, the second alignment groove 423 of the second adjustment part 420 can be aligned with the first alignment groove 413 of the first adjustment part 410, so that the teeth of the gear 20 correspond to the tooth grooves of the internal gear ring 30. With such a setting, it is possible to judge whether the teeth of the gear 20 correspond to the tooth grooves of the internal gear ring 30 by determining whether the second alignment groove 423 and the first alignment groove 413 are aligned, which improves the convenience of adjusting the gear 20.

[0106] When there are multiple gears 20, the above steps can be sequentially performed on the multiple gears 20 to make the teeth of the multiple gears 20 all correspond to the tooth grooves of the internal gear ring 30.

[0107] S7. Pull out the adjustment rod to raise the transmission to the second preset height, and take out the second adjustment part and the first adjustment part.

[0108] Exemplarily, first pull out the adjustment rod 430 from the adjustment hole 422. Then, control the overhead crane to raise the transmission 10 to the second preset height, so as to facilitate taking out the second adjustment part 420 and the first adjustment part 410 from between the gear 20 and the internal gear ring 30. Exemplarily, when the transmission 10 is at the second preset height, the distance between the bottom surface of the transmission 10 and the end surface of the internal gear ring 30 can be made greater than the height of either the first adjustment part 410 or the second adjustment part 420, so that the second adjustment part 420 and the first adjustment part 410 can be taken out from between the gear 20 and the internal gear ring 30 and avoid interference between the second adjustment part 420 and the first adjustment part 410 and the transmission 10.

[0109] It should be noted that during the process of raising the transmission 10 to the second preset height, although the transmission 10 and the gear 20 will vibrate slightly, the gear 20 will not rotate relative to the transmission 10 due to its own gravity. That is to say, there is no need to align the teeth of the gear 20 and the tooth grooves of the internal gear ring 30 again.

[0110] S8. Lower the transmission and place the teeth of the gear into the tooth grooves of the internal gear ring.

[0111] Exemplarily, the transmission 10 can be lowered by controlling a hoisting device such as an overhead crane to place the teeth of the gear 20 into the tooth grooves of the internal gear ring 30, thereby completing the assembly of the gear 20 and the internal gear ring 30.

[0112] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
