[0030] The following are detailed descriptions of specific embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0031] The following refers to the attached Figure 1 to the attached Figure 3 to describe the disassembly and assembly tool for a gear transmission mechanism of the present utility model.

[0032] The present utility model provides a disassembly and assembly tool for a gear transmission mechanism, wherein the disassembly and assembly tool for a gear transmission mechanism includes:

[0033] a positioning plate 1;

[0034] a positioning end cover 2, which is arranged on the positioning plate 1 and is used to cover the end of the main gear shaft of the gear transmission mechanism;

[0035] The card mounting seat 3 is connected to the positioning plate 1 and forms a clamping portion 31 spaced relative to the positioning plate 1. The clamping portion 31 is arranged on the same side as the positioning end cover 2 and has a clamping opening 310 through which the secondary gear shaft of the gear transmission mechanism can pass. Moreover, the clamping portion 31 is also used to carry the gears in the gear transmission mechanism in the picking and placing state.

[0036] When using the disassembly and assembly tooling for the above gear transmission mechanism, the operator covers the positioning end cover 2 on the end of the main gear shaft of the transmission mechanism to position the entire disassembly and assembly tooling on the gear transmission mechanism. Then, the operator horizontally inserts the clamping portion 31 of the card mounting seat 3 into the tooth gap on the secondary gear shaft, so that the shaft body of the secondary gear shaft enters the clamping opening 310 of the clamping portion 31, and the secondary gear at the upper end of the secondary gear shaft is placed between the clamping portion 31 and the positioning plate 1. Then, through this disassembly and assembly tooling for the gear transmission mechanism, the operator can use a hoisting device to hoist the pre-assembled gear transmission mechanism as a whole into the box, or hoist the gear transmission mechanism in the box to the maintenance platform and then disassemble it. The disassembly and assembly process of the gear transmission mechanism is no longer limited by the space size of the box, which is convenient for the operator to carry out disassembly and maintenance, especially for tooth alignment and assembly of all gears during the maintenance process, and can effectively improve the disassembly and assembly efficiency of the gear transmission mechanism.

[0037] It should be noted that the disassembly and assembly tooling provided by the present invention is applicable to a variety of gear transmission mechanisms, and is particularly applicable to the gear transmission mechanism of a gearbox. The gear transmission mechanism of the gearbox includes a main gear shaft, a secondary gear shaft, and a connecting member for connecting the main and secondary gear shafts. The number of secondary gear shafts can be single or two or more. A number of gears are correspondingly arranged on each gear shaft to achieve different transmission ratios. There are gaps between some vertically adjacent gears. The clamping portion 31 of the card mounting seat 3 can correspondingly extend into the gap to realize clamping with the secondary gear shaft, and cooperate with a hoisting device to hoist and transport the gear transmission mechanism.

[0038] The gear transmission mechanism of the gearbox generally has one main gear shaft and two secondary gear shafts. The two secondary gear shafts are symmetrically arranged on both sides of the main gear shaft. For this type of gear transmission mechanism, in some embodiments of the present invention, the number of card mounting seats 3 is two. The two card mounting seats 3 are spaced from the positioning end cover 2 along the length direction of the positioning plate 1, so that the secondary gear shafts on both sides of the main gear shaft can be correspondingly clamped one by one, and the two card mounting seats 3 are used to respectively carry the gears of the gear transmission mechanism from opposite ends.

[0039] Specifically, the two clamping seats 3 are arranged opposite to each other along the width direction of the positioning plate 1, and the two clamping seats 3 can be clamped to the two secondary gear shafts one by one from two opposite directions, so as to limit the front and rear sides and the left and right sides of the gear transmission mechanism at the same time. Compared with the solution of arranging the two clamping seats 3 on the same side of the positioning plate 1, it can prevent the gear transmission mechanism from falling out of the clamping seats 3 due to shaking during the lifting process. Of course, the utility model is not limited to this. If the space between the gear transmission mechanism and its box in the width direction is small and there is more space in the length direction, it is also possible for the two clamping seats to be arranged opposite to each other along the length direction of the positioning plate 1.

[0040] In addition, the card seat 3 can also be set as a single card seat, and two card openings 310 are provided on the single card seat 3. The two card openings 310 correspond to two auxiliary gear shafts respectively, so as to realize the support on both sides of the gear transmission mechanism.

[0041] In the embodiment of the utility model, the card seat 3 also includes a connecting portion 32, which is arranged on the side of the card connection portion 31 away from the card connection opening 310, and the end of the connecting portion 32 away from the card connection portion 31 is detachably connected to the positioning plate 1. The operator first sets the positioning end cover 2 on the end of the main gear shaft, then snaps the positioning seat with the secondary gear shaft, and finally assembles the snap seat with the positioning plate 1. The detachable setting facilitates the operator to snap the transmission mechanism in a box with limited space.

[0042] In the embodiment of the utility model, the connecting portion 32 includes a vertical section 321 and a horizontal plate section 322. The horizontal plate section 322 is detachably arranged on the side of the positioning plate 1 away from the positioning end cover 2, and one end of the horizontal plate section 322 horizontally extends out of the positioning plate 1 along the width direction of the positioning plate 1, and the vertical section 321 extends from the end of the horizontal plate section 322 extending out of the positioning plate 1 toward the side provided with the positioning end cover 2 and connects the clamping portion 31. The horizontal plate section 322 overlaps the upper side of the positioning plate 1. Compared with the solution of connecting the connecting portion 32 to the lower side of the positioning plate 1, the gravity of the gear transmission mechanism is directly transmitted to the positioning plate 1 through the clamping seat, and the horizontal plate section 322 has a large area, so the gravity can be more evenly dispersed to the positioning plate 1, reducing the contact stress per unit area. The fastener 4 between the clamping seat and the positioning plate 1 is only used for connection and does not bear the gravity of the gear transmission mechanism.

[0043] In the embodiment of the present utility model, the positioning plate 1 is formed with a first through hole, the connecting portion 32 is formed with a second through hole 320, the clamping seat 3 further includes a fastener 4 passing through the first through hole and the second through hole 320. The first through hole extends along the width direction of the positioning plate 1, and the second through hole 320 extends along the length direction of the positioning plate 1. That is, the first through hole and the second through hole 320 form a cross-shaped adjustment space, so as to change the distance between the clamping seat and the positioning end cover 2 according to different models of the gear transmission mechanism, and improve the versatility of the disassembly and assembly tooling.

[0044] Furthermore, since the two sub-gears of the gear transmission mechanism are symmetrically arranged on both sides of the main gear shaft, the positioning end cover 2 is arranged at the center position of the positioning plate 1. By sleeving the upper end portion of the main gear shaft with the positioning end cover 2, the two clamping seats are positioned, ensuring that the positions of the two clamping seats to the center point of the positioning end cover 2 are the same after the position adjustment through the above-mentioned first through hole and the second through hole 320, so as to ensure that the torques on both sides of the positioning plate 1 are the same, and further ensure the balance of both sides of the tooling and the transmission mechanism during the hoisting project, so as to achieve the purpose of reducing shaking.

[0045] In the embodiment of the present utility model, a supporting portion 33 protruding upward is further provided on the side of the clamping portion 31 facing the positioning plate 1. The supporting portion 33 is used to support the main gear on the main gear shaft upward. In the gear transmission mechanism, there are differences in the thickness between the meshing main gear and the sub-gear. Usually, the thickness of the sub-gear is greater than that of the main gear. The setting of the supporting portion 33 can provide a supporting point for the main gear to improve the stability of the gear transmission mechanism during hoisting. Specifically, the number of clamping seats is two, and the above-mentioned supporting portions are provided on the sides of the two clamping seats close to the main gear shaft. The main gear is lifted by the left supporting portion and the right supporting portion to prevent the main gear shaft from sinking and the gear transmission mechanism from swaying left and right.

[0046] Furthermore, the supporting portion 33 is formed with a threaded hole, and a threaded member is rotatably inserted into the threaded hole. By rotating the threaded member, the height of the threaded member protruding upward from the supporting portion 33 can be changed, so as to adjust the position of the threaded member according to the height difference between the sub-gear supported by the clamping portion 31 and the meshing main gear, so that the threaded member can just abut against the lower end surface of the main gear, and improve the versatility of the tooling.

[0047] In the embodiment of the present utility model, the disassembly and assembly tooling for the gear transmission mechanism further includes a reinforcing beam 6 arranged on the clamping seat 3. The reinforcing beam 6 extends along the outer surface of the clamping seat 3. Specifically, two reinforcing beams 6 are arranged on one clamping seat 3, and the two reinforcing beams 6 are symmetrically arranged along the width direction of the clamping seat 3 to enhance the overall structural strength of the tooling and prevent the clamping seat 3 from deforming.

[0048] In the embodiment of the present utility model, a lifting ring 5 is further provided on the side of the positioning plate 1 away from the positioning end cover 2, and the lifting ring 5 is used to connect a lifting device. The lifting ring 5 is arranged at the center position of the positioning plate 1 to ensure equal gravity on both sides during lifting and ensure the stability of the lifting process.

[0049] Specifically, according to the above-mentioned disassembly and assembly tooling for the gear transmission mechanism, the gear transmission mechanism inside the gearbox can be taken out as a whole for maintenance and arrangement. The specific operation process is as follows:

[0050] The first step: Take the positioning plate 1 and use the positioning end cover 2 on the lower side of the positioning plate 1 to cover the upper part of the main gear shaft.

[0051] The second step: Insert the clamping part 31 of the clamping seat 3 on the left side into the lower gap of the first sub-gear on the left-side sub-gear shaft, and use the supporting part of the clamping seat 3 on the left side to lift the lower end of the adjacent main gear.

[0052] The third step: Insert the clamping part 31 of the clamping seat 3 on the right side into the lower gap of the first sub-gear on the right-side sub-gear shaft, and use the supporting part of the clamping seat 3 on the right side to lift the lower end of the adjacent main gear.

[0053] The fourth step: Fix and connect the clamping seats on the left and right sides to the positioning plate 1 respectively through bolts.

[0054] The fifth step: Connect the hook or sling of the lifting device to the lifting ring 5, and control the lifting device to safely lift the gear transmission mechanism out of the box body.

[0055] Taking the gearbox of a truck crane as an example, the old disassembly and assembly process required two maintenance personnel to operate together for twelve hours to complete the disassembly and assembly tooling of the gearbox; after using the above tooling and method, one maintenance personnel can complete the disassembly and assembly work in one hour. And the disassembly and assembly process can be carried out on the corresponding maintenance platform, avoiding the risk of gears falling and hurting people.
