Description

Technical Field

[0001] This invention relates to the field of integrated main reduction gear assembly technology, specifically to an integrated main reduction gear assembly pad selection device. Background Technology

[0002] The integral main reducer assembly is a one-piece cast structure. During the assembly process, torque shims and imprint shims are required according to assembly needs. The torque shims are used to adjust the clearance of the upper and lower cone bearings in the main cone assembly to ensure that the torque of the main cone assembly reaches the ideal state. The imprint shims are used to adjust the vertical position of the main cone assembly to ensure that the meshing of the driving bevel gear and the driven bevel gear reaches the ideal state.

[0003] The current selection method for torque shims and imprinted shims mainly involves selecting the two shims independently. Torque shims are selected by moving the bearings up and down, that is, measuring the downward displacement distance of the upper bearing and the upward displacement distance of the lower bearing respectively, and calculating the shim thickness by subtracting the standard clearance distance of the bearing from the two measurements. Imprinted shims are selected by measuring the theoretical installation distance three times for the housing, bearing, and main cone, and calculating the shim thickness by subtracting the installation distances at the three locations.

[0004] The above method of selecting gaskets has the following disadvantages:

[0005] 1. The two gaskets are measured independently, and 3-5 dedicated measuring devices are required, which is time-consuming, involves many procedures, and results in poor equipment utilization.

[0006] 2. Both shims were selected by calculating the difference between the actual distance and the theoretical distance to obtain the theoretical result. This method requires relatively ideal consistency in the quality of the parts and does not consider other influencing factors. In actual production, the torque and meshing state produced by the theoretical result may not be qualified due to the influence of various factors.

[0007] 3. The accuracy of the gasket selection in the two parts of the production process is subject to a certain lag. If the selection is incorrect, it will require a lot of cost for rework and repair. In particular, the selection of imprint gaskets, the qualified inspection of gear meshing imprints is located at the end of the production process. If the inspection process is not qualified, the entire main reducer assembly will have to be disassembled and reassembled. To this end, we propose an integrated main reducer assembly gasket selection device. Summary of the Invention

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] Please see Figures 1-11 The diagram shows an integrated main reduction gear assembly pad selection device, comprising:

[0041] The integrated main reduction assembly, located above the operating console 3, includes a main cone shaft 101 and a main bevel gear 102 fixed to one end of the main cone shaft 101. The main cone shaft 101 is sequentially equipped with a lower cone bearing 103, a first spacer 104, a driven gear 105, a rotating driven gear 106, a second spacer 107, an upper cone bearing 108, and a roller bearing 109. It also includes:

[0042] A support component for supporting the integrated main reduction assembly is set between the control panel 3 and the integrated main reduction assembly. The control panel 3 is equipped with a shim detection device for the rotational torque of the shim during the shim selection process and a shim imprint detection device.

[0043] The support assembly includes a lower bearing fixing sleeve 201 and an upper bearing fixing sleeve 202 respectively sleeved on the outside of the lower tapered bearing 103 and the roller bearing 109. The upper end of the operating table 3 is slidably connected to two sets of lower bearing slides 203 and upper bearing slides 204 for assisting in supporting the lower bearing fixing sleeve 201 and the upper bearing fixing sleeve 202. A transmission assembly for assisting transmission during the detection process is provided between the driven gear 106 and the lower bearing fixing sleeve 201. A distance sensor for identifying the sliding distance of the lower bearing fixing sleeve 201 during the support process is installed on the lower bearing slide 203.

[0044] It should be noted that during the assembly of the integrated main reduction gear assembly, the torque shim and the imprint shim are simultaneously tested and selected using the torque shim testing equipment and the imprint shim testing equipment on the shim selection equipment. During the selection process, the torque and gear meshing imprint are used as direct evaluation criteria to avoid the problem of deviation from the actual results by the purely theoretical size calculation scheme. In addition, during the torque shim testing process, the load of the driven cylindrical gear transmission and the oil churning resistance of the shaft rotation are simulated to ensure that the test results are close to the actual vehicle installation state.

[0045] The transmission assembly includes a push ring 401 fixed to one side of the driven gear 106. The driven gear 106 and the push ring 401 are concentrically arranged. A transmission cylinder 403 is connected to the push ring 401 by multiple sets of fixing pins 402. The transmission cylinder 403 is threadedly engaged with the inner side of the lower bearing fixing sleeve 201. A rotating assembly for rotating the driven gear 105 is provided on the upper bearing slide 204.

[0046] It should be noted here that: by rotating the assembly, the driven gear 106 is rotated. During the rotation of the driven gear 106, the transmission cylinder 403 is driven to rotate through the connection of the push ring 401 and each set of fixing pins 402. During the rotation of the transmission cylinder 403, the lower bearing fixing sleeve 201 is slowly moved away from the front end of the main bevel gear 102 through the thread engagement between the transmission cylinder 403 and the inner side of the lower bearing fixing sleeve 201.

[0047] The rotating assembly includes a mounting bracket 501 fixed on the upper bearing slide 204. A first motor 502 is fixed at the upper end of the mounting bracket 501. A transmission gear 503 is fixed at the output end of the first motor 502. The transmission gear 503 is meshed with the driven gear 106. A first cylinder 7 for moving the upper bearing slide 204 is provided on the operating table 3.

[0048] It should be noted here that: the transmission gear 503 is driven to rotate by the first motor 502. During the rotation of the transmission gear 503, the driven gear 106 is rotated by the meshing transmission between the transmission gear 503 and the driven gear 106.

[0049] Preferably, the torque shim testing device includes a drive assembly for driving the main tapered shaft 101 and a first clamping assembly and a second clamping assembly for clamping the driven gear 105. The drive assembly includes a first slide 601 slidably connected to the operating table 3. A second cylinder 602 for pushing the first slide 601 is installed on the operating table 3. A mounting platform 603 is fixed to the upper end of the first slide 601. A mounting motor 604 is fixed on the mounting platform 603. A connecting shaft 605 is fixed to the output end of the mounting motor 604. A threaded tightening head 606 for threaded connection with the main tapered shaft 101 is fixed to one end of the connecting shaft 605. An elastic component for abutting against the inner side of the upper tapered bearing 108 is provided on the outer side of the threaded tightening head 606. A lubrication resistance component for generating lubrication resistance during transmission is provided on the connecting shaft 605.

[0050] It should be noted here that: the first slide 601 is driven by the second cylinder 602 to move toward the placed integral main reduction assembly. During the movement, the mounting motor 604 rotates at low speed. The rotation of the mounting motor 604 and the movement of the entire first slide 601 drive the threaded tightening head 606 to rotate, so that the threaded tightening head 606 is tightened with the end of the main cone shaft 101 in a threaded manner.

[0051] Preferably, the elastic component includes a clamping head 801 sleeved on the outside of the threaded tightening head 606. The outer side of the clamping head 801 has multiple sets of sliding grooves 802. Each set of sliding grooves 802 is slidably connected to a sliding pin 803. The sliding pin 803 is connected and fixed to the outer side of the threaded tightening head 606 by a connecting rod 804. The inside of the sliding groove 802 is provided with a spring for elastically connecting the sliding pin 803.

[0052] It should be noted here that the sliding groove 802, sliding pin 803 and spring facilitate the elastic connection of the pressing head 801.

[0053] Preferably, the first clamping assembly includes a second slide 901 slidably connected to the upper end of the operating table 3, a third cylinder 902 for driving the second slide 901 is installed on the operating table 3, and a clamping block 903 for abutting and rubbing against the driven gear 105 is fixed on the second slide 901.

[0054] It should be noted here that the clamping block 903 is abutted against one side of the driven gear 105 by the driving action of the third cylinder 902.

[0055] Preferably, the second clamping assembly includes a third slide 1001 slidably connected to the upper end of the operating table 3, a fourth cylinder 1002 for pushing the third slide 1001 is installed on the operating table 3, a clamping box 1003 for abutting and clamping against the driven gear 105 is provided on one side of the third slide 1001, a fifth cylinder 1004 for pushing the clamping box 1003 is installed on the third slide 1001, and a meshing assembly for meshing transmission during the detection process and a load assembly for the load during the transmission process are provided on the third slide 1001.

[0056] It should be noted here that: through the driving action of the fifth cylinder 1004, the clamping box 1003 on the front side of the third slide 1001 abuts against one side of the driven gear 105.

[0057] Preferably, the meshing assembly includes a support frame 1101 fixed on the third slide 1001, a first load gear 1102 rotatably connected to the support frame 1101, a drive shaft 1103 rotatably connected to the support frame 1101, a second load gear 1104 for meshing with the driven gear 105 fixed on the drive shaft 1103, the second load gear 1104 and the first load gear 1102 are meshed with each other, and the clamping box 1003 is provided with a mounting groove 1105 for assisting in the sliding connection of the drive shaft 1103;

[0058] It should be noted here that the third slide 1001 is moved by the pushing action of the fourth cylinder 1002, and the movement of the third slide 1001 causes the second load gear 1104 on the support frame 1101 to mesh with the driven gear 105.

[0059] Preferably, the load assembly includes a rectangular frame 1201 fixed on a support frame 1101, and a friction brake 1202 for rubbing against the outside of the first load gear 1102 is mounted on the rectangular frame 1201.

[0060] It should be noted here that during the rotation of the connecting shaft 605, the friction brake 1202 activates its braking function to clamp the first load gear 1102, simulating the transmission resistance during the main reduction operation.

[0061] Preferably, the lubrication resistance assembly includes a cylinder cover 1301 disposed on the front side of the mounting motor 604. The cylinder cover 1301 is filled with lubricating oil. The cylinder cover 1301 is connected and fixed to the mounting platform 603 by multiple sets of mounting pins 1302. A connecting shaft 605 is rotatably connected to the cylinder cover 1301, and a load blade 1303 is fixed on the side wall inside the cylinder cover 1301 of the connecting shaft 605.

[0062] It should be noted here that during the rotation of the connecting shaft 605, the load blade 1303 is driven to rotate. Since the inside of the hydraulic cylinder cover 1301 is filled with liquid of a specified density, the rotation of the load blade 1303 simulates the lubricating oil resistance of the main bevel gear 102.

[0063] Preferably, the imprint pad testing equipment includes a vision inspection bracket 1401 fixed to the upper end of the operating table 3, a detection shaft 1402 rotatably connected to the vision inspection bracket 1401, a process driven bevel gear 1403 for meshing and driving with the main bevel gear 102 fixed on the detection shaft 1402, a vision camera 1404 for detecting meshing imprints mounted on the vision inspection bracket 1401, an imprint paint liquid tank 1405 and a testing frame 1406 fixed on the operating table 3, the imprint paint liquid tank 1405 is filled with imprint paint, the process driven bevel gear 1403 is located inside the imprint paint liquid tank 1405, an imprint paint recovery tank 1407 for collecting the flying imprint paint is mounted on the testing frame 1406, and an air-filled separation component for freezing and separating the imprint paint is provided on the detection shaft 1402.

[0064] It should be noted that during the imprint pad detection process, the second load gear 1104 is not engaged with the driven gear 105 through transmission. The integrated main reduction assembly is moved by the first cylinder 7. During the movement, the main bevel gear 102 meshes with the process driven bevel gear 1403. Through the meshing transmission between the main bevel gear 102 and the process driven bevel gear 1403, the process driven bevel gear 1403 is rotated. The lower end of the process driven bevel gear 1403 is immersed in the imprint coating liquid tank 1405. After passing through the imprint coating liquid tank 1405, the tooth surface of the process driven bevel gear 1403 is covered with imprint coating. It rotates upward and contacts the main bevel gear 102 to generate an engagement imprint. It then rotates upward to reach the detection range of the vision camera 1404 for the actual identification of the engagement imprint.

[0065] Preferably, the inflation separation assembly includes a mounting tube 1501 fixed on the visual inspection bracket 1401, and a nozzle 1502 is mounted on the mounting tube 1501, with the nozzle 1502 facing the ink recovery tank 1407.

[0066] It should be noted that: the process driven bevel gear 1403 rotates continuously until it reaches the position covered by the dry ice high-pressure cleaning nozzle 1502. The dry ice high-pressure cleaning nozzle 1502 sprays a high-speed, high-pressure airflow of dry ice, which quickly freezes and blows off the printing coating on the surface of the process driven bevel gear 1403 into the printing coating recovery tank 1407. After the printing coating melts, it flows back into the printing coating liquid tank 1405.

[0067] In this solution: an integrated main reduction gear assembly pad selection device includes the following steps:

[0068] During the assembly of the integrated main reduction gear assembly, the torque shims and imprint shims required for the assembly process are selected using a shim selection device. During the shim selection process, the integrated main reduction gear assembly is placed on the operating table 3. During the placement process, the lower bearing mounting sleeve 201 and the upper bearing mounting sleeve 202 on the integrated main reduction gear assembly are supported by the lower bearing slide 203 and the upper bearing slide 204 respectively.

[0069] After the integrated main reduction gear assembly is placed and supported, the thickness of the torque shim is tested. During the test, the locking action of the first cylinder 7 prevents the lower bearing slide 203, the upper bearing slide 204, and the integrated main reduction gear assembly after support placement from sliding on the operating table 3, i.e., the upper tapered bearing 108 cannot move. The second cylinder 602 drives the first slide 601 to move towards the placed integrated main reduction gear assembly. During the movement, the mounting motor 604 rotates at low speed. The rotation of the mounting motor 604 and the movement of the entire first slide 601 drive the threaded tightening head 606 to rotate, causing the threaded tightening head 606 to engage with the main tapered shaft 10. The end of 1 is tightened with a threaded cap. After tightening, the clamping head 801, along with the continued sliding of the first slide 601 and the spring force pushing the clamping head 801, presses the clamping head 801 against the inner ring of the upper tapered bearing 108. Through transmission, the clamping block 903 and the clamping box 1003 clamp the driven gear 105. The third slide 1001 is moved by the pushing action of the fourth cylinder 1002. Through the movement of the third slide 1001, the second load gear 1104 on the support frame 1101 meshes with the driven gear 105. At this time, the motor 604 drives the connecting shaft 605 to rotate. During the rotation of the connecting shaft 605, the driven gear 105 on the main bevel gear 102 is driven to rotate via transmission. During the rotation of the driven gear 105, the rotational torque of the main bevel gear 102 is detected. During rotation, the friction brake 1202 engages its braking function, clamping the first load gear 1102 to simulate the transmission resistance during the main reducer operation. During the rotation of the connecting shaft 605, the load blade 1303 is driven to rotate. Since the inside of the cylinder cover 1301 is filled with a liquid of a specified density, the rotation of the load blade 1303 simulates the lubricating oil resistance of the main bevel gear 102. During the detection process, the... The driven gear 106 is rotated by the rotating assembly. During the rotation of the driven gear 106, the transmission cylinder 403 is driven to rotate through the connection of the push ring 401 and each set of fixing pins 402. During the rotation of the transmission cylinder 403, the transmission cylinder 403 is driven to rotate slowly away from the front end of the main bevel gear 102 through the thread engagement between the transmission cylinder 403 and the inner side of the lower bearing fixing sleeve 201, until the rotational torque reaches the specified torque. At this time, the motor 604 stops rotating. The distance sensor on the lower bearing fixing sleeve 201 identifies the sliding distance of the lower bearing fixing sleeve 201, which is the thickness of the rotational torque shim.

[0070] During the imprint pad inspection process, the second load gear 1104 is prevented from meshing with the driven gear 105 via transmission. The first cylinder 7 drives the placed integrated main reduction assembly to move. During this movement, the main bevel gear 102 meshes with the process driven bevel gear 1403. This meshing transmission drives the process driven bevel gear 1403 to rotate. The lower end of the process driven bevel gear 1403 is immersed in the imprint coating liquid tank 1405. After passing through the imprint coating liquid tank 1405, the tooth surface of the process driven bevel gear 1403 is coated with imprint coating. It then rotates upwards to contact the main bevel gear 102, creating an imprint. Further upward rotation brings it within the detection range of the vision camera 1404, thus completing the imprint detection. The process is judged by continuously rotating the driven bevel gear 1403 until it reaches the position covered by the dry ice high-pressure cleaning nozzle 1502. The dry ice high-pressure cleaning nozzle 1502 sprays a high-speed, high-pressure airflow of dry ice to quickly freeze and blow off the imprint coating on the surface of the driven bevel gear 1403 into the imprint coating recovery tank 1407. After the imprint coating melts, it flows back into the imprint coating liquid tank 1405. The above process is repeated to detect the gear meshing imprint in real time. During the detection process, the first cylinder 7 slowly moves the entire integrated main reduction assembly forward until the meshing imprint detected by the vision camera 1404 reaches the specified qualified range. At this time, the distance sensor identifies the sliding distance of the lower bearing fixing sleeve 201. The difference between this distance and the theoretical installation distance of the reduction housing is the thickness of the imprint gasket.
