Description

[0002] Reducers are generally used in transmission equipment with low speed and high torque. During the operation of the reducer, it is often necessary to add lubricating oil to reduce wear. However, since the internal gears of the reducer will inevitably generate a lot of heat during use, if the rotating joints are lubricated at this time, it is easy to reduce the lubrication effect, resulting in increased gear wear. The common reducer lubrication system on the market cannot promptly determine whether the reducer is stuck during operation, resulting in the lubricating oil being sprayed for a long time, resulting in poor contact at the rotating connection point. Therefore, it is of great significance to design a self-lubricating reducer that can spray lubrication according to the speed or jam. Summary of the invention

[0033] Furthermore, a bearing sleeve 22 is provided on the inner side of the rotating pipe 30, and a rotating conical shaft 14 is rotatably provided inside the bearing sleeve 22. An inclined plate 27 inclined inwardly is provided on both sides of the bottom of the shell 10 on one side of the bearing sleeve 22, and an oil drain port 26 is provided on the inclined inner angle side of the inclined plate 27 at the bottom of the shell 10.

[0034] Working principle: The operator unscrews the oil tank cover 13 upwards, then pours the lubricating oil into the oil filling tank 11, and then tightens the oil tank cover 13 again.

[0035] During use, the rotating cone shaft 14 is connected to the input end shaft, and the output shaft 17 is connected to the output end shaft, and then the power is turned on to operate. First, the rotating cone shaft 14 rotates, thereby driving the first bevel gear 20 set at one end of the rotating cone shaft 14 to rotate, thereby driving the second bevel gear 31 meshing therewith to rotate, thereby driving the first rotating shaft 23 set on the second bevel gear 31 to rotate, thereby driving the first gear 32 set on the first rotating shaft 23 to rotate, thereby driving the second gear 33 meshing therewith to rotate, thereby driving the second rotating shaft 24 set on the second gear 33 to rotate, thereby driving the third gear 34 set on the second rotating shaft 24 to rotate, thereby driving the fourth gear 35 meshing therewith to rotate, thereby driving the output shaft 17 set on the fourth gear 35 to rotate, thereby completing the speed increase and decrease through the different transmission ratios between the gear components.

[0036] During the rotation of the second gear 33, the second gear 33 will also drive the sixth gear 37 meshing therewith to rotate, thereby driving the power-generating shaft 25 arranged in the sixth gear 37 to rotate, thereby driving the rotating power-generating block 12 arranged on the power-generating shaft 25 to generate electricity. The rotating power-generating block 12 will transmit the electricity to the electromagnetic plate 19 above, so that the electromagnetic plate 19 generates magnetic force, so that the magnetic baffles 46 below both sides of the electromagnetic plate 19 can absorb and seal the infusion pipe 38. The electromagnetic plate 19 will also transmit the magnetic force to the magnetic rod 48, and then release the magnetic force through the bottom magnetic head 54, so that the magnetic block 53 is adsorbed to ensure the sealing of the connecting pipe 49.

[0037] When the gear assembly inside the reducer gets stuck, or the speed of the external motor decreases or even stops, the rotating power generating block 12 cannot generate too much electricity to maintain the magnetism. At this time, the magnetic attraction baffle 46 under the electromagnetic plate 19 cannot be attracted, and slides downward, so that the infusion pipeline 38 begins to be unblocked. At this time, the first drive motor 29 arranged on one side of the oil filling pipeline 21 will be started, and the output end of the first drive motor 29 drives the impeller shaft 39 to rotate, thereby driving the rotating impeller 40 arranged on the impeller shaft 39 to rotate, thereby driving the infusion pipeline 38 and the oil filling tank 11 to enter the oil filling pipeline 21 faster. After the oil enters the oil filling pipeline 21, it will be sprayed to the gear assembly through the oil spray head 28 on one side of the oil filling pipeline 21, thereby lubricating the gear assembly, thereby ensuring that there will be no jamming during use.

[0038] When the electromagnetic plate 19 has no power, the magnetic rod 48 arranged on one side of the electromagnetic plate 19 will also be unable to generate magnetic force, so that the magnetic head 54 on the bottom side of the magnetic rod 48 will also lose its magnetic force, so that the magnetic block 53 on one side of the magnetic head 54 will be dragged downward by the second spring 51 at the bottom, so that a gap will appear in the sealing fit between the blocking ring 52 and the magnetic block 53, so that the oil in the oil filling tank 11 can enter the connecting pipe 49, and then enter the oil inlet pipe 55 through the hose on the outside of the connecting pipe 49, and then enter the lubrication tank 15 through the oil inlet pipe 55.

[0039] At this time, if the equipment is still rotating, the previous rotation process of the rotating cone shaft 14 will also drive the rotating cam 41 to rotate, so that the convex points of the rotating cam 41 come into contact with the abutment plates 45 on both sides, thereby pushing the abutment plates 45 inward, thereby pushing the piston rod 43 arranged on one side of the abutment plates 45 to move inward, thereby pushing the piston plate 42 arranged on one side of the piston rod 43 to move inward, thereby compressing the space of the piston base 57 on one side of the piston plate 42, thereby making the space in the lubrication chamber 15 smaller, so that the gas in the space will be sprayed outward through the third oil spray head 59 and the second oil spray head 56. When the lubricating liquid is not injected, the third oil spray head 59 and the second oil spray head 56 will only spray gas, thereby The dust at the rotating cone shaft 14 and the dirt at other places are removed to ensure the continuity of rotation. When the convex point of the rotating cam 41 moves away, the piston plate 42 will return to its position under the action of the first spring 44, so that the space in the lubrication chamber 15 becomes larger, and then the third oil spray head 59 and the second oil spray head 56 will pump air to ensure the next jet. If the lubricating liquid enters the lubrication chamber 15, the third oil spray head 59 and the second oil spray head 56 will spray lubricating oil to lubricate the rotating joint. In this relationship, the third oil spray head 59 mainly lubricates the rotating cone shaft 14, and the second oil spray head 56 lubricates the rotating parts such as the second bevel gear 31 and the first bevel gear 20. During the lubrication process, if too much lubricating oil is sprayed, it will fall on the inclined plate 27 and then be discharged through the oil drain port 26 at the bottom.
