Description

Technical Field

[0001] This utility model belongs to the field of transmission gear technology, and more specifically, it relates to an improved transmission gear. Background Technology

[0002] Transmission gears are a common component in mechanical transmission systems, primarily used to transmit power and motion through the meshing of gears. They are typically used to change speed, direction, or transmit torque. Transmission gears are widely used in various mechanical devices, such as automobiles, machine tools, and industrial equipment.

[0003] Based on the above, the inventors have discovered the following problems: In the process of using existing transmission gears, the teeth of the gears are prone to wear after prolonged friction and the lubricant is consumed, which reduces the transmission efficiency and thus reduces the service life of the gears.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide an improved transmission gear, in order to achieve a more practical value. Utility Model Content

[0005] The purpose and effect of this improved transmission gear are achieved by the following specific technical means:

[0006] An improved transmission gear includes a gear body, a shaft hole on the surface of the gear body, a protrusion on one side of the shaft hole, a plurality of teeth on the outer surface of the gear body, and a lubrication assembly mounted on the gear body.

[0007] Furthermore, the lubrication assembly includes a liquid storage tank located inside the gear body. A plurality of limiting holes are provided on one side of the liquid storage tank, and the limiting holes extend to the outside of the gear body. A slide rod is slidably installed inside the limiting holes. A sliding plate is installed at one end of the slide rod, and a spring is installed on one side of the sliding plate. A sliding groove is provided on one side of the limiting holes, and one end of the spring is connected to the sliding groove. A sealing block is installed at the bottom end of the slide rod.

[0008] Furthermore, the spring is slidably mounted on the periphery of the slide rod.

[0009] Furthermore, the end of the slide rod located outside the gear body is an arc surface.

[0010] Furthermore, the sealing block is located inside the liquid storage tank.

[0011] Furthermore, a number of first-level baffles are installed on one side of the liquid storage tank, and a number of second-level baffles are installed on the other side of the liquid storage tank. The first-level baffles and second-level baffles are staggered, and the surfaces of the first-level baffles and second-level baffles are provided with through holes.

[0012] Furthermore, a pair of heat dissipation grooves are provided on both sides of the gear body, and a number of heat dissipation holes are provided on one side of the pair of heat dissipation grooves.

[0013] Furthermore, an oil injection hole is provided on one side of the gear body, one end of the oil injection hole is connected to the liquid storage tank, a sealing plug is threaded to one side of the oil injection hole, and a rubber ring is installed on the periphery of one end of the sealing plug.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Through the coordinated use of the reservoir, limiting hole, slide rod, sliding plate, spring, sliding groove, and sealing block, when the teeth mesh together, the arc surface of the slide rod is squeezed, and the slide rod moves into the limiting hole. At the same time, the sealing block is pushed into the reservoir. The lubricant in the reservoir flows into the limiting hole and out along the slide rod to the surface of the teeth, which improves the lubrication of the teeth surface, improves transmission efficiency, reduces friction and wear, and improves the service life of the gears. The spring squeezes the sliding plate, pushing the slide rod out of the limiting hole. The sealing plug blocks one end of the limiting hole to prevent excessive flow of lubricant and extend the service life of the lubricant.

[0016] By using the combination of baffle one, baffle two and through hole, baffle one and baffle two are staggered to obstruct the lubricant in the reservoir, prevent the lubricant from flowing too fast when the gear rotates at high speed, avoid temperature rise, avoid the viscosity of the lubricant from decreasing, and improve the coating effect of the lubricant on the tooth surface.

[0017] By using heat dissipation slots and holes in combination, the gears can be cooled, preventing them from overheating and reducing transmission efficiency, thus improving overall transmission efficiency. Attached Figure Description

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 4 As shown:

[0029] This utility model provides an improved transmission gear, including a gear body 1, a shaft hole 2 on the surface of the gear body 1, a protrusion 3 installed on one side of the shaft hole 2, a plurality of teeth 4 installed on the outer surface of the gear body 1, and a lubrication component installed on the gear body 1.

[0030] The lubrication assembly includes a liquid storage tank 7 located inside the gear body 1. A plurality of limiting holes 11 are provided on one side of the liquid storage tank 7. The limiting holes 11 extend to the outside of the gear body 1. A slide rod 13 is slidably installed inside the limiting holes 11. A slide plate 16 is installed at one end of the slide rod 13. A spring 14 is installed on one side of the slide plate 16. A sliding groove 12 is provided on one side of the limiting holes 11. One end of the spring 14 is connected to the sliding groove 12. A sealing block 15 is installed at the bottom end of the slide rod 13.

[0031] The spring 14 is slidably mounted on the periphery of the slide rod 13.

[0032] The slide bar 13 has an arc-shaped end located outside the gear body 1.

[0033] The sealing block 15 is located in the liquid storage tank 7. Through the cooperation between the liquid storage tank 7, the limiting hole 11, the slide rod 13, the sliding plate 16, the spring 14, the sliding groove 12 and the sealing block 15, when the teeth 4 mesh with each other, the arc surface of the slide rod 13 is squeezed, and the slide rod 13 moves into the limiting hole 11. At the same time, the sealing block 15 is pushed into the liquid storage tank 7. The lubricant in the liquid storage tank 7 flows into the limiting hole 11 and flows out along the slide rod 13 to the surface of the teeth 4, which improves the lubrication of the surface of the teeth 4, improves the transmission efficiency, reduces friction and wear, and improves the service life of the gear. The spring 14 squeezes the sliding plate 16 and pushes the slide rod 13 out of the limiting hole 11. The sealing plug 17 blocks one end of the limiting hole 11 to prevent excessive flow of lubricant and extend the service life of the lubricant.

[0034] The liquid storage tank 7 has several baffles 8 installed on one side and several baffles 9 installed on the other side. The baffles 8 and 9 are staggered. The surfaces of the baffles 8 and 9 are provided with through holes 10. Through the cooperation between the baffles 8, 9 and 10, and the staggered distribution of the baffles 8 and 9, the lubricant in the liquid storage tank 7 can be obstructed, preventing the lubricant from flowing too fast when the gear rotates at high speed, avoiding temperature rise, avoiding viscosity reduction of the lubricant, and improving the coating effect of the lubricant on the surface of the gear teeth 4.

[0035] The gear body 1 has a pair of heat dissipation grooves 5 on both sides, and a plurality of heat dissipation holes 6 on one side of the pair of heat dissipation grooves 5. Through the cooperation between the heat dissipation grooves 5 and the heat dissipation holes 6, the gear can be cooled, avoiding excessive gear temperature and resulting in a decrease in transmission efficiency, thus improving transmission efficiency.

[0036] The gear body 1 has an oil injection hole 19 on one side. One end of the oil injection hole 19 is connected to the liquid storage tank 7. A sealing plug 17 is threaded to one side of the oil injection hole 19. A rubber ring 18 is installed on the periphery of one end of the sealing plug 17. The oil injection hole 19 can inject lubricant into the liquid storage tank 7. The sealing plug 17 blocks the oil injection hole 19, and the rubber ring 18 prevents lubricant leakage.

[0037] The specific usage and function of this embodiment are as follows:

[0038] First, check the integrity of the device. Only use it after confirming it is intact. During use, first inject lubricant into the reservoir 7 through the oil injection hole 19. Then, seal the oil injection hole 19 with the sealing plug 17 and use the rubber ring 18 to prevent lubricant leakage. When the teeth 4 mesh, the other teeth 4 press against the arc surface of the gear slide rod 13, causing the slide rod 13 to move into the limiting hole 11. Simultaneously, this pushes the sealing block 15 into the reservoir 7. The lubricant in the reservoir 7 flows into the limiting hole 11 and out along the slide rod 13 to the surface of the teeth 4, improving the lubrication of the teeth 4 surface, increasing transmission efficiency, reducing friction and wear, and extending the service life of the gears. Spring 14 presses against slide plate 16, pushing slide rod 13 outwards towards limiting hole 11. Sealing plug 17 blocks one end of limiting hole 11 to prevent excessive lubricant outflow and extend lubricant service life. Stop block 1 8 and stop block 2 9 are staggered to obstruct the lubricant in reservoir 7, preventing the lubricant from flowing too fast when the gear rotates at high speed, avoiding temperature rise, preventing the lubricant viscosity from decreasing, and improving the coating effect of lubricant on the tooth surface 4. Heat dissipation groove 5 and heat dissipation hole 6 dissipate the high temperature generated by gear and reservoir 7, improving transmission efficiency. This device has a novel overall design and simple structure, and is therefore worthy of widespread promotion and use.
