[0023] like Figure 1 and Figure 4 As shown, the mounting mechanism 2 includes a fixed block 201 fixedly connected to the top of the base plate 1, a slot 202 is provided on the top of the fixed block 201, and the mounting block 3 is movably inserted into the slot 202. The slot 202 on the top of the fixed block 201 is movably connected to the mounting block 3, providing a preliminary positioning and mounting structure for the gear box, so that the mounting block 3 can be placed on the fixed block 201 quickly and accurately, reducing the alignment adjustment time during installation, laying the foundation for subsequent stable fixation, and improving the convenience of installation.

[0024] like Figure 1 、 Figure 4 and Figure 5As shown, a groove 203 is provided at the bottom of the mounting block 3, and two limiting holes 204 are provided on the inner side of the groove 203, and a limiting groove 205 is provided on the inner side of the slot 202. A bidirectional screw rod 206 is rotatably connected in the limiting groove 205, and two movable plates 207 are threadedly installed on the outer surface of the bidirectional screw rod 206, and the two movable plates 207 are slidably connected in the limiting groove 205. Through the cooperation between the groove 203 and the limiting groove 205, combined with the bidirectional screw rod 206, the movable plate 207 is driven to slide in the limiting groove 205, so that the movable plate 207 can accurately correspond to the limiting hole 204 on the mounting block 3. The movement of the movable plate 207 can realize the limiting fixation of the mounting block 3, enhance the stability of the connection between the mounting block 3 and the fixed block 201, and avoid displacement of the gear box due to vibration during operation.

[0025] like Figure 4 and Figure 5 As shown, one side of the two movable plates 207 is fixedly connected to two limit rods 208, and the smooth end of the bidirectional screw rod 206 is movable through the limit groove 205 and the fixed block 201 and is installed with a turning handle 209.

[0026] like Figure 7 and Figure 8 As shown, the internal helical planetary gear mechanism 5 includes an inner ring gear 501 fixedly arranged in the housing 4, and three planetary gears 502 are meshedly mounted on the inner surface of the inner ring gear 501, and three rotating shafts 503 are fixedly connected to the inner surfaces of the three planetary gears 502. The planetary gears 502 are internal helical planetary gears, and the inner ring gear 501 is an internal helical inner ring gear. The three planetary gears 502 are meshed with the inner ring gear 501 and are connected through the rotating shafts 503, so that the planetary gears 502 can rotate while revolving around the sun gear 506. The design of the internal helical teeth increases the overlap of the gear meshing, improves the transmission stability and load-bearing capacity, and can better meet the needs of high-power transmission.

[0027] like Figure 7 and Figure 8As shown, the outer surfaces of the three rotating shafts 503 are connected to two planetary carriers 504 through bearings, and the inner side of the box body 4 is connected to the input shaft 505 through a bearing. One end of the input shaft 505 movably passes through one of the planetary carriers 504 and is fixedly connected to the sun gear 506. The two planetary carriers 504 are connected to the rotating shaft 503 through bearings, providing stable support for the planetary gears 502 to ensure their stability during operation; the input shaft 505 drives the sun gear 506 to rotate, and the sun gear 506 engages with the planetary gears 502 to drive the planetary gears 502 to move. The planetary gear transmission structure is compact, can achieve a large transmission ratio in a small space, and improves the power transmission efficiency.

[0028] like Figure 7 and Figure 8 As shown, the sun gear 506 is meshed with the three planetary gears 502 respectively, and the inner side of the box body 4 is connected to the rotating rod 507, the first output shaft 508 and the second output shaft 509 through bearings. The outer surface of the rotating rod 507 is fixedly sleeved with a driving gear 510, which drives the rotating rod 507 to rotate through the planetary carrier 504. The driving gear 510 on the rotating rod 507 is meshed with two driven gears 511, thereby driving the first output shaft 508 and the second output shaft 509 to rotate, realizing the dual output function and meeting the scene requirements of driving different working parts at the same time.

[0029] like Figure 7 and Figure 8 As shown, two driven gears 511 are fixedly sleeved on the outer surfaces of the first output shaft 508 and the second output shaft 509, and the driving gear 510 is meshed with the two driven gears 511 respectively. One end of the rotating rod 507 is fixedly connected to the other planetary carrier 504. Since the driving gear 510 and the driven gear 511 are both internal helical gears, the internal helical teeth of the driving gear 510 and the driven gear 511 further ensure the stability and reliability of the dual output transmission.

[0030] like Figure 1 、 Figure 6 and Figure 9 As shown, an oil storage tank 613 and an oil pump 614 are fixedly installed on the top of the box body 4. The input end of the oil pump 614 is connected to the interior of the oil storage tank 613 through a pipeline, and the output end of the oil pump 614 is fixedly connected to a telescopic tube 615. The end of the telescopic tube 615 away from the oil pump 614 is movable and passes through the box body 4 and is connected to the interior of the cross pipe 605. A continuous source of lubricating oil is provided through the oil storage tank 613. The oil pump 614 can extract the lubricating oil from the oil storage tank 613 and transport it to the cross pipe 605 through the telescopic tube 615. The telescopic characteristics of the telescopic tube 615 adapt to the movement state of the cross pipe 605 swinging with the rotating block 604, ensuring that the lubricating oil can be stably transported to the nozzle 606, thereby ensuring the normal operation of the oil injection lubrication mechanism 6.

[0031] like Figure 3 As shown, one side of the box body 4 is fixedly connected to two oil drain pipes 7, and two control valves 8 are installed on the two oil drain pipes 7. The used lubricating oil in the box body 4 can be discharged through the oil drain pipes 7; the control valve 8 can control the opening and closing of the oil drain, which is convenient for the operator to perform the oil drain operation according to the needs and avoid the lubricating oil from leaking at will. At the same time, it is also convenient for the operator to collect and process the discharged lubricating oil.

[0032] The usage and working principle of this device: During the installation and fixing stage, align the installation block 3 with the slot 202 on the top of the fixed block 201 and insert it. At the same time, the two movable plates 207 enter the groove 203. Then, rotate the handle 209 to rotate the bidirectional screw rod 206, driving the two movable plates 207 to move away from each other in the limit groove 205, so that the two limit rods 208 are inserted into the two limit holes 204, completing the installation and fixing of the gear box; when disassembling, rotate the handle 209 in the opposite direction, so that the two movable plates 207 drive the two limit rods 208 to move relative to each other in the limit groove 205 and disengage from the limit hole 204, and the installation block 3 and the box body 4 can be removed.

[0033] During the startup phase, the power source is connected to the input shaft 505 to start the device. The input shaft 505 drives the sun gear 506 to rotate. The sun gear 506 engages with the three planetary gears 502, driving the planetary gears 502 to rotate while revolving around the sun gear 506. The planetary gears 502 engage with the inner ring gear 501, driving the planetary carrier 504 to rotate. The planetary carrier 504 drives the rotating rod 507 to rotate. The driving gear 510 on the rotating rod 507 engages with the driven gears 511 on the first output shaft 508 and the second output shaft 509, thereby realizing dual output transmission of the first output shaft 508 and the second output shaft 509.

[0034] During the oil injection lubrication stage, by starting the servo motor 612 and the oil pump 614, the oil pump 614 transports the lubricating oil in the oil tank 613 to the cross pipe 605 through the telescopic tube 615, and then sprays it out through the nozzle 606; at the same time, the servo motor 612 drives the reciprocating screw 608 to rotate, so that the moving block 609 moves along the guide rail 607, and the rack 611 on one side of the moving block 609 engages with the spur gear 610, driving the movable rod 603 to rotate. The movable rod 603 drives the cross pipe 605 and the nozzle 606 to swing back and forth through the rotating block 604, thereby expanding the oil injection range and ensuring that the lubricating oil evenly covers the gear meshing area.
