[0002] A gearbox is a mechanical transmission device used to change the speed, torque, and direction of rotational motion. It usually consists of a series of intermeshing gears installed in a closed housing to protect the gears and provide good lubrication conditions. Gearboxes are of many types, such as planetary gearboxes, parallel shaft gearboxes, worm gearboxes, etc. Each type has its specific characteristics and applicable scenarios. The design and manufacture of gearboxes for injection molding machines need to consider the working characteristics and process requirements of the injection molding machine. In terms of material selection, high-strength alloy steel is usually used, which is precision machined and heat treated to ensure the hardness and wear resistance of the gears. At the same time, the optimized lubrication and cooling system helps to reduce the operating temperature of the gearbox and extend its service life.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention sets an output mechanism. When the working efficiency of the injection molding machine needs to be changed, the main motor controls the gear 1 to rotate. Due to the limitation of the position of the arc groove, the support column 1 is pushed to move outward, thereby driving the support plate 1 and the movable plate to move outward, thereby controlling the four planetary gear mechanisms to move up, down, left and right respectively, thereby controlling the planetary gear mechanisms and the output mechanism to mesh with different radii, thereby changing the output power of the injection molding machine without changing the output efficiency of the main motor, thereby achieving the effect of power saving.

[0018] 2. The present invention sets an output mechanism. When the power of the injection molding machine needs to be changed, as the output mechanism drives the planetary gear mechanism to move, the telescopic rod will also drive the support frame to move toward the planetary gear mechanism. Due to the limiting effect of the retaining ring, the output shaft will also be driven to move. After the planetary gear mechanism and the gear plate mechanism are meshed, the output shaft will be driven to rotate, thereby driving the fan blades to rotate, thereby generating wind force at the meshing point, reducing the temperature of the meshing point, and avoiding damage to the device due to excessive temperature due to long-term use. Since the output shaft will move, the insertion rod will move along the inner wall of the insertion column, but will never separate from the insertion column, thereby ensuring that the output shaft can always drive the rotating disk to rotate, and then drive the output port to rotate.

[0019] 3. The present invention sets a toothed disc mechanism. When the high-speed shaft contacts the gear three on the secondary plate or the gear two on the tertiary plate, it drives the entire toothed disc mechanism to rotate, thereby controlling the output shaft to rotate. Since each gear needs to be lubricated regularly, it is time-consuming and laborious to remove the box body to apply the lubricating oil. By pouring the lubricating oil into the oil pipe, after the lubricating oil enters the oil storage column, when the toothed disc mechanism rotates, the centrifugal force generated by the rotation will cause the lubricating oil to enter the oil pipe and flow into the gear two and gear three, thereby realizing automatic lubrication, and there is no need to disassemble the box body for manual lubrication.

[0020] 4. The present invention provides an oiling mechanism and a planetary gear mechanism. Since the planetary gear mechanism may face the problem of poor heat dissipation when it is in high power and long-term continuous operation, as the low-speed shaft flange of the planetary gear mechanism rotates, it will drive the outer gear to rotate. When the planetary gear mechanism moves along the sliding groove close to the position of gear four, gear four will mesh with the outer gear and drive the worm to rotate, thereby driving the worm wheel to rotate, and finally causing the fan blades to rotate, thereby cooling the planetary gear mechanism. At the same time, as the worm rotates, the rotating shaft two and the brush sleeve will also be driven to rotate, so that the brush sleeve will come into contact with gear two or gear three sprayed with lubricating oil, so that the lubricating oil is evenly spread. At the same time, the brush sleeve will also come into contact with the scraper plate to scrape off excess lubricating oil attached to the brush sleeve or dust attached when in contact with the outside world.

[0036] Example 1, using Figure 1-Figure 13 A high torque four-in-one injection molding machine dedicated gearbox according to one embodiment of the present invention is described below.

[0037] like Figure 1-Figure 3 As shown, the high-torque four-in-one injection molding machine special gearbox of the present invention comprises a box body 1, a support seat 2 is symmetrically arranged at the bottom of the box body 1, notches 4 are evenly arranged on the outer surface of the box body 1, an input mechanism 3 is fixedly connected to the back of the box body 1, an output mechanism 5 is fixedly connected to one end of the box body 1 away from the input mechanism 3, a main motor 7 is fixedly connected to the outer surface of the input mechanism 3, and an oiling mechanism 6 is evenly arranged on the inner wall of the box body 1;

[0038] When the gearbox dedicated to the high-torque four-in-one injection molding machine is working, the servo motor will first drive the output mechanism 5 to work, thereby realizing different coordination between the output mechanism 5 and the input mechanism 3, thereby controlling the working power of the injection molding machine. As the output mechanism 5 works, the oiling mechanism 6 will also be driven to work, so as to cool and lubricate the output mechanism 5 and the transmission structure in the output mechanism 5.

[0039] like Figure 4-Figure 5 As shown, the input mechanism 3 includes a side plate 31, a side of the side plate 31 away from the main motor 7 is evenly provided with a sliding groove 32, the output end of the main motor 7 is fixedly connected with a gear 33, the gear 33 is provided with an arc groove 34, the inner wall of the sliding groove 32 is slidably connected with a support plate 36, the outer surface of the support plate 36 is fixedly connected with a support column 35, the outer surface of the support column 35 is slidably connected with the outer surface of the arc groove 34, the end of the support plate 36 away from the support column 35 is fixedly connected with a moving plate 37, the outer surface of the moving plate 37 is fixedly connected with a planetary gear mechanism 38, and the number of the planetary gear mechanisms 38 is four;

[0040] The main motor 7 controls the gear 33 to rotate. Due to the position limitation of the arc groove 34, the support column 35 is pushed to move outward, thereby driving the support plate 36 and the movable plate 37 to move outward, thereby controlling the four planetary gear mechanisms 38 to move up, down, left and right respectively, thereby controlling the planetary gear mechanisms 38 to mesh with the output mechanism 5 at different radii, thereby changing the output power of the injection molding machine without changing the output efficiency of the main motor 7, thereby achieving the effect of saving electricity.

[0041] like Figure 6-Figure 7As shown, the planetary gear mechanism 38 includes a built-in motor 381, the output end of the built-in motor 381 is fixedly connected to a low-speed shaft flange 382, ​​the end of the low-speed shaft flange 382 away from the built-in motor 381 is fixedly connected to a bearing 3810, the outer surface of the bearing 3810 is fixedly connected to an end cover 383, the outer surface of the low-speed shaft flange 382 is fixedly connected to an external gear 389, the end of the end cover 383 away from the external gear 389 is fixedly connected to a gear ring 385, the inner ring of the bearing 3810 is fixedly connected to a planet carrier 384, the end of the planet carrier 384 away from the bearing 3810 is evenly provided with planetary gears 386, the outer surface of the planetary gear 386 is meshed with a sun gear 387, one end of the sun gear 387 is rotatably connected to the planet carrier 384, and the end of the sun gear 387 away from the planet carrier 384 is fixedly connected to a high-speed gear 388, and the length of the high-speed gear 388 is relatively long.

[0042] The built-in motor 381 will drive the low-speed shaft flange 382 to rotate, and then drive the inner layer of the bearing 3810 to rotate, and drive the planetary carrier 384 and the planetary gear 386 to rotate. Since the ring gear 385 and the planetary gear 386 are meshing, the planetary gear 386 will rotate along the ring gear 385, and finally drive the sun gear 387 to rotate. As the low-speed shaft flange 382 rotates, the outer gear 389 will also rotate.

[0043] The side of the side plate 31 away from the main motor 7 is fixedly connected to the outer surface of the box body 1, and the outer surface of the built-in motor 381 is fixedly connected to the side of the side plate 31 away from the main motor 7.

[0044] The specific workflow is as follows:

[0045] During operation, the main motor 7 controls the gear 33 to rotate. Due to the position limitation of the arc groove 34, the support column 35 is pushed to move outward, thereby driving the support plate 36 and the movable plate 37 to move outward, thereby controlling the four planetary gear mechanisms 38 to move up, down, left and right respectively, thereby controlling the planetary gear mechanism 38 to mesh with the output mechanism 5 at different radii, thereby changing the output power of the injection molding machine without changing the output efficiency of the main motor 7. When the planetary gear mechanism 38 is working, the built-in motor 381 drives the low-speed shaft flange 382 to rotate, and then drives the inner layer of the bearing 3810 to rotate, and drives the planetary carrier 384 and the planetary gear 386 to rotate. Since the ring gear 385 and the planetary gear 386 are meshed, the planetary gear 386 will rotate along the ring gear 385, and finally drive the sun gear 387 to rotate. As the low-speed shaft flange 382 rotates, the outer gear 389 will also rotate.

[0046] Example 2, using Figure 1-Figure 13 A high torque four-in-one injection molding machine dedicated gearbox according to one embodiment of the present invention is described below.

[0047] like Figure 8-Figure 9 As shown, the high torque four-in-one injection molding machine special gearbox of the present invention is based on the first embodiment, the output mechanism 5 includes a second side plate 51, the outer surface of the second side plate 51 is evenly provided with telescopic rods 52, the end of the telescopic rod 52 away from the second side plate 51 is fixedly connected to the support frame 53, the middle part of the support frame 53 is rotatably connected to the output shaft 54, the side of the output shaft 54 ​​close to the support frame 53 is fixedly connected to the retaining ring 55, the side of the output shaft 54 ​​is fixedly connected to the toothed disc mechanism 56, the outer surface of the output shaft 54 ​​is fixed A fan blade 57 is fixedly connected to the side panel 51 away from the telescopic rod 52, and a cooling bin 58 is fixedly connected to the end of the cooling bin 58 away from the side panel 51, and a protruding plate 59 is fixedly connected to the inner wall of the protruding plate 59. An insertion column 510 is fixedly connected to the end of the output shaft 54 ​​away from the gear mechanism 56, and insertion rods 512 are evenly arranged on the side of the rotating disk 511 close to the insertion column 510, and an output port 513 is fixedly connected to the end of the rotating disk 511 away from the insertion rod 512.

[0048] When the power of the injection molding machine needs to be changed, as the output mechanism 5 drives the planetary gear mechanism 38 to move, the telescopic rod 52 will also drive the support frame 53 to move toward the planetary gear mechanism 38. Due to the limiting effect of the retaining ring 55, the output shaft 54 ​​will also be driven to move. After the planetary gear mechanism 38 and the gear mechanism 56 are engaged, the output shaft 54 ​​will be driven to rotate, thereby driving the fan blades 57 to rotate, thereby generating wind force on the meshing point, reducing the temperature of the meshing point, and avoiding damage to the device due to excessive temperature due to long-term use. Since the output shaft 54 ​​will move, the insertion rod 512 will move along the inner wall of the insertion column 510, but will never separate from the insertion column 510, thereby ensuring that the output shaft 54 ​​can always drive the rotating disk 511 to rotate, and then drive the output port 513 to rotate.

[0049] The outer surface of the second side plate 51 is fixedly connected to an end of the box body 1 away from the first side plate 31 , and the outer surface of the insertion rod 512 is slidably connected to the inner wall of the insertion column 510 .

[0050] like Figure 10-11 As shown, the gear mechanism 56 includes a primary plate 561, an end of the primary plate 561 away from the output shaft 54 ​​is fixedly connected to a secondary plate 562, an end of the secondary plate 562 away from the primary plate 561 is fixedly connected to a tertiary plate 563, an end of the tertiary plate 563 away from the secondary plate 562 is fixedly connected to an oil storage column 564, a side of the oil storage column 564 away from the tertiary plate 563 is rotatably connected to a rotating block 565, an outer surface of the rotating block 565 is fixedly connected to an oil pipe 566, an outer surface of the secondary plate 562 is fixedly connected to a gear three 568, an outer surface of the tertiary plate 563 is fixedly connected to a gear two 567, and an outer surface of the oil storage column 564 is evenly provided with oil pipes 569.

[0051] When the high-speed gear 388 changes from being meshed with gear two 567 to being meshed with gear three 568, the rotation speed of the output shaft 54 ​​will decrease. Similarly, when the high-speed gear 388 changes from being meshed with gear three 568 to being meshed with gear two 567, the rotation speed of the output shaft 54 ​​will increase, thereby changing the power of the injection molding machine. At the same time, since it is necessary to lubricate each gear at a regular interval, it is time-consuming and laborious to remove the box body 1 to apply the lubricating oil. By pouring the lubricating oil into the oil pipe 566, after the lubricating oil enters the oil storage column 564, when the toothed disc mechanism 56 rotates, the centrifugal force generated by the rotation will cause the lubricating oil to enter the oil pipe 569 and flow into gear two 567 and gear three 568, thereby realizing automatic oiling, and there is no need to dismantle the box body 1 for manual oiling.

[0052] The outer surface of the primary plate 561 is fixedly connected to one end of the output shaft 54 ​​, and the oil pipe 566 passes through the outer surface of the tertiary plate 563 and extends to the inner wall of the primary plate 561 .

[0053] The outer surface of the high-speed gear 388 meshes with the outer surface of gear two 567 , and the outer surface of the high-speed gear 388 meshes with the outer surface of gear three 568 .

[0054] like Figure 12-13 As shown, the oiling mechanism 6 includes a fixed plate 61, the outer surface of the fixed plate 61 is fixedly connected to the support plate 2 62, the outer surface of the support plate 2 62 is rotatably connected to the gear 4 63, the end of the gear 4 63 away from the support plate 2 62 is fixedly connected to the worm 64, the end of the fixed plate 61 close to the support plate 2 62 is symmetrically provided with a rotating shaft 1 65, the outer surface of the rotating shaft 1 65 is fixedly connected to the worm gear 66, the end of the rotating shaft 1 65 away from the support plate 2 62 is fixedly connected to the fan blade 67, the end of the worm 64 away from the gear 4 63 is fixedly connected to the rotating shaft 2 68, the outer surface of the rotating shaft 2 68 is fixedly connected to the brush sleeve 69, the inner wall of the notch 4 is fixedly connected to the support rod 610, and the outer surface of the support rod 610 is fixedly connected to the scraper plate 611.

[0055] Since the planetary gear mechanism 38 may face the problem of poor heat dissipation when it runs continuously for a long time at high power, as the low-speed shaft flange 382 of the planetary gear mechanism 38 rotates, it will drive the outer gear 389 to rotate. When the planetary gear mechanism moves along the sliding groove 32 close to the position of gear four 63, gear four 63 will mesh with the outer gear 389 and drive the worm 64 to rotate, thereby driving the worm wheel 66 to rotate, and finally causing the fan blade 67 to rotate, thereby cooling the planetary gear mechanism 38. At the same time, as the worm 64 rotates, the rotating shaft 2 68 and the brush sleeve 69 will also be driven to rotate, so that the brush sleeve 69 will come into contact with the gear 2 567 or the gear 3 568 sprayed with lubricating oil, so that the lubricating oil is evenly applied. At the same time, the brush sleeve 69 will also come into contact with the scraper plate 611 to scrape off excess lubricating oil attached to the brush sleeve 69 or dust attached when in contact with the outside world.

[0056] The outer surface of the fixing plate 61 is fixedly connected to the inner wall of the box body 1 , and the outer surface of the worm wheel 66 is threadedly connected to the outer surface of the worm 64 .

[0057] The outer surface of the gear four 63 meshes with the outer surface of the external gear 389 , and the outer surface of the scraper plate 611 contacts the end of the brush sleeve 69 away from the rotating shaft 2 68 .

[0058] The specific workflow is as follows:

[0059] During operation, when the power of the injection molding machine needs to be changed, as the output mechanism 5 drives the planetary gear mechanism 38 to move, the telescopic rod 52 will also drive the support frame 53 to move toward the planetary gear mechanism 38. Due to the limiting effect of the retaining ring 55, the output shaft 54 ​​will also be driven to move. After the planetary gear mechanism 38 and the toothed disc mechanism 56 are meshed, the output shaft 54 ​​will be driven to rotate, thereby driving the fan blades 57 to rotate, thereby generating wind force on the meshing part, reducing the temperature of the meshing part, and avoiding damage to the device caused by excessive temperature due to long-term use. Since the output shaft 54 ​​will move, the insertion rod 512 will move along the inner wall of the insertion column 510 at this time, but will never separate from the insertion column 510, thereby ensuring that the output shaft 54 ​​can always drive the rotating disk 511 to rotate, and then drive the output port 513 to rotate. When the high-speed gear 388 changes from meshing with gear two 567 to meshing with gear three 568, the output The rotation speed of the output shaft 54 ​​will decrease. Similarly, when the high-speed gear 388 changes from meshing with gear three 568 to meshing with gear two 567, the rotation speed of the output shaft 54 ​​will increase, thereby changing the power of the injection molding machine. Finally, when the planetary gear mechanism moves along the sliding groove 32 and approaches the position of gear four 63, gear four 63 will mesh with the outer gear 389 and drive the worm 64 to rotate, thereby driving the worm wheel 66 to rotate, and finally causing the fan blade 67 to rotate, thereby cooling the planetary gear mechanism 38. At the same time, as the worm 64 rotates, the shaft two 68 and the brush sleeve 69 will also be driven to rotate, so that the brush sleeve 69 will come into contact with gear two 567 or gear three 568 sprayed with lubricating oil, thereby evenly spreading the lubricating oil. At the same time, the brush sleeve 69 will also come into contact with the scraper plate 611 to scrape off excess lubricating oil attached to the brush sleeve 69 or dust attached when in contact with the outside world.

[0060] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
