[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 - Figure 4 , an embodiment provided by the utility model: a high-speed gear with self-lubricating function, including a gear hub 1, a through groove 6 is opened on the right surface of the gear hub 1, an oil delivery component 3 is arranged on the inner wall of the gear hub 1, and a positioning component 8 is arranged on the upper surface of the left end of the oil delivery component 3, and a rectangular groove 7 is opened on the upper surface of the gear hub 1, and the inner wall of the rectangular groove 7 contacts with a tooth 2, and the bottom of the tooth 2 is adapted to the rectangular groove 7 to ensure the stability of the connection. At the same time, when the tooth 2 is inserted into the inner wall of the rectangular groove 7, it is necessary to ensure that the rectangular groove 9 opened on the front surface of the bottom end of the tooth 2 faces the left to ensure that the plug-in block 43 can be smoothly inserted therein, and an oil outlet hole 5 is opened on the outer wall of the gear hub 1. The centrifugal force generated during movement will throw out the lubricating oil, and the lubricating oil will flow to the teeth 2 through the oil outlet 5, reducing the wear rate of the teeth 2. A disassembly component 4 is provided on the left surface of the gear hub 1. The oil delivery component 3 includes an oil delivery column 31. The inner wall space of the oil delivery column 31 has a certain slope, which slowly descends from the right to the left end to ensure that the lubricating oil can flow smoothly from the right end to the left end. The outer wall of the left end of the oil delivery column 31 contacts the inner wall of the gear hub 1, and the outer wall of the right end of the oil delivery column 31 is rotatably connected with a sealing ring 32. A through hole 36 is opened on the upper surface of the right end of the oil delivery column 31. There are multiple groups of through holes 36, and the center of the oil delivery column 31 is used as the original circumference array to ensure that the lubricating oil can smoothly enter the interior of the oil delivery column 31.

[0034] Reference Figure 2 , Figure 4 , Figure 6The disassembly component 4 includes a plug-in block 43, which is slidably connected to the left surface of the gear hub 1. A rubber block 44 is fixedly connected to the front surface of the plug-in block 43. The rubber block 44 has a certain elasticity, and its left surface and right surface have a certain amplitude to ensure that when the ring 41 is pulled, the rubber block 44 will smoothly come out from the inner wall of the clamping groove 10. At the same time, when the ring 41 is pulled, the rubber block 44 will be deformed by its own elasticity, and it will quickly return to its original state after the extrusion is completed. The left surface of the plug-in block 43 is fixedly connected to the ring 41, and the left surface of the ring 41 is threadedly connected with a bolt 42. The bolt 42 is provided with multiple groups to ensure the stability of the connection. The bolt 42 is threadedly connected to the left surface of the gear hub 1.

[0035] Reference Figure 3 , Figure 5 The positioning assembly 8 includes a positioning shell 82, which penetrates and slides through the upper surface of the left end of the oil delivery column 31, and the top of the positioning shell 82 contacts the inner wall of the oil outlet hole 5. The positioning shell 82 is inserted into the inner wall of the oil outlet hole 5 to ensure that the lubricating oil can smoothly enter the inner wall of the oil outlet hole 5, and the lubricating oil will not flow to the connection between the oil delivery column 31 and the gear hub 1, thereby ensuring the stability of the connection. The outer wall of the top of the positioning shell 82 is set as an arc surface, and the set arc surface ensures that the positioning shell 82 can be quickly positioned.

[0036] Reference Figure 1 - Figure 2 The upper surface of the sealing ring 32 is fixedly connected to an oil pipe 33, and the lower surface of the rear end of the oil pipe 33 is provided with an oil suction pump 34. The oil suction pump 34 is a prior art, and its main body is fixed on the oil storage tank 35 and connected to the oil storage tank 35 through a pipeline, so as to transport the lubricating oil inside the oil storage tank 35 out. The lower surface of the oil suction pump 34 is fixedly connected to the oil storage tank 35, and the rear end of the upper surface of the oil storage tank 35 is provided with an oil inlet pipe to ensure that the workers can refuel smoothly.

[0037] Reference Figure 4 , Figure 6 A rectangular groove 29 is provided on the left surface of the bottom end of the tooth 2, and a clamping groove 10 is provided on the inner wall of the rectangular groove 29. The plug-in block 43 contacts the inner wall of the rectangular groove 29, and the rubber block 44 contacts the inner wall of the clamping groove 10. The rubber block 44 is adapted to the clamping groove 10 to ensure the stability of the connection.

[0038] Reference Figure 3 , Figure 5The outer wall of the positioning shell 82 is sleeved with a spring 83. The spring 83 always pushes the positioning shell 82 upward through its own elasticity to ensure that the positioning shell 82 is in close contact with the inner wall of the oil outlet hole 5 to ensure the sealing effect. One end of the spring 83 is fixedly connected to the upper surface of the positioning shell 82, and the other end of the spring 83 is fixedly connected to the inner wall of the oil delivery column 31. The positioning assembly 8 also includes a positioning block 81, which is fixedly connected to the rear surface of the left end of the oil delivery column 31. The positioning block 81 slides on the inner wall of the through groove 6. The positioning block 81 and the through groove 6 are interference fit. The interference fit ensures that the connection between the oil delivery column 31 and the gear hub 1 is more stable.

[0039] Working principle: When in use, the oil delivery column 31 needs to be installed together with the driving equipment, so that the gear hub 1 and the teeth 2 can be driven to rotate. When the gear hub 1 and the teeth 2 rotate, the oil suction pump 34 can be started, and the oil suction pump 34 will suck out the lubricating oil inside the oil storage tank 35, and spray it into the inside of the sealing ring 32 through the oil delivery pipe 33. The lubricating oil entering the inside of the sealing ring 32 will enter the inside of the oil delivery column 31 through the through hole 36. The lubricating oil will flow along the inclined surface of the inner wall of the oil delivery column 31 from the right end of the oil delivery column 31 to the left end of the oil delivery column 31. Then, the lubricating oil will pass through the centrifugal force generated by the rotation of the high-speed gear and enter the inner wall of the oil outlet hole 5 through the positioning shell 82. In this way, the lubricating oil will flow to the surface of the gear hub 1 and the teeth 2, lubricate the high-speed gear, and avoid damage to the high-speed gear.

[0040] When the gear hub 1 needs to be disassembled for inspection, the worker only needs to pull the oil delivery column 31 and the gear hub 1 in two directions to disengage the positioning block 81 from the inner wall of the through groove 6. When disengaging, the positioning shell 82 will move out from the inner wall of the oil outlet hole 5 through its own arc surface, and the positioning shell 82 will stretch the spring 83. When installing, it is only necessary to insert the oil delivery column 31 into the inner wall of the gear hub 1 and ensure that the positioning block 81 completely enters the inner wall of the through groove 6. The positioning shell 82 and spring 83 are set to move in the same way as above. The positioning shell 82 will be inserted into the inner wall of the oil outlet hole 5 to ensure that the lubricating oil can smoothly enter the inner wall of the oil outlet hole 5 to avoid leakage.

[0041] If the tooth 2 is worn and needs to be replaced, it is only necessary to use a tool to turn down the bolt 42. At this time, pull the ring 41, and the ring 41 drives the plug-in block 43 to move until the plug-in block 43 is separated from the inner wall of the rectangular groove 9 to replace the damaged tooth 2. During installation, it is only necessary to insert the tooth 2 into the inner wall of the rectangular groove 7, and then push the ring 41 in the opposite direction. In the process of inserting the plug-in block 43 into the inner wall of the rectangular groove 9, the rubber block 44 will be squeezed and deformed until the rubber block 44 overlaps with the clamping groove 10. At this time, the rubber block 44 will restore its original shape through its own elasticity and enter the inner wall of the clamping groove 10 to ensure the stability of the connection. Then the ring 41 can be tightened by the bolt 42.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
