Description

Technical Field

[0001] The utility model relates to the technical field of mechanical transmission gears, and more specifically, to a mechanical transmission gear. Background Art

[0002] In the existing gear technology for mechanical transmission, gears will usually wear out after long-term use. This is because the gears are constantly subjected to contact force and friction during the meshing process. In order to reduce this wear, the existing technical means usually adopt the method of manually applying lubricating oil for maintenance. This method requires regular lubrication of the gears to keep the gears running smoothly and extend their service life. However, this method of manually applying lubricating oil brings many adverse effects.

[0003] First of all, manual application of lubricating oil requires manual operation, which increases the labor intensity and operational risks of workers. Workers need to enter the gear working area to apply the lubricating oil, which poses certain safety risks. At the same time, due to the viscosity of the lubricating oil, it is easy to cause uneven application during manual application, resulting in insufficient lubrication in some areas of the gear and excessive lubrication in some areas, affecting the operating performance and life of the gear.

[0004] Secondly, some devices in the prior art adopt an automatic lubrication and maintenance structure, which can automatically provide lubricating oil to the gears, reducing the frequency and risk of manual operation. However, the automatic lubrication and maintenance structure in the prior art is too simple and cannot flexibly adjust the oil output of the maintenance device according to usage requirements. This inflexible lubrication method may cause insufficient or excessive lubrication of the gears during operation, affecting the operating performance and life of the gears.

[0005] In addition, the automatic lubrication and maintenance structure in the prior art is usually not convenient for oiling after the lubricating oil is used up. This may be because the location of the lubricating oil storage container is not convenient for operation, or the design of the oil filling port is unreasonable, which makes it impossible to replenish the lubricating oil in time after it is exhausted. This situation will cause the gears to run without lubricating oil, accelerate wear, and may even cause equipment failure and shutdown. Utility Model Content

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides a gear for mechanical transmission, which has the following beneficial effects:

[0019] 1. The design of the maintenance device, including sealing blocks, top blocks, oil storage tanks, oil outlet pipes, push rods, sealing plates, connecting plates, springs and fixed plates, realizes the function of automatic lubrication and maintenance. During the rotation of the gears, the push rods are pressed against the teeth to drive the sealing plate to move. At the same time, the top block will push the sealing block open to release the lubricating oil. This design reduces the need for manual application of lubricating oil, reduces the labor intensity of workers, and improves operational safety. The structure of the sealing block and the spring ensures the controllability of the oil output, while preventing the leakage of lubricating oil, thereby improving the service life and operating efficiency of the gears.

[0020] 2. The design of the adjustment mechanism, including the limit plate, limit groove, threaded plate, limit rod, hexagonal block, hexagonal groove and screw and other components, allows flexible adjustment of the oil output each time according to the use requirements. Through the operation of an external hexagonal wrench, the distance between the threaded plate and the sealing plate can be changed, thereby adjusting the pressure applied by the push spring to the sealing plate. At the same time, the distance between the top block and the sealing block is controlled, and the size of the gap generated when the sealing block moves is changed, so as to achieve precise adjustment of the oil output. This design improves the flexibility and adaptability of the maintenance device and ensures that the lubrication needs of the gear under different working conditions are met.

[0021] 3. The design of the oil filling device, including the oil filling port, the oil filling pipe, and the sealing cover, makes it easy to carry out the oil filling operation after the lubricating oil is used up. By removing the sealing cover, the lubricating oil in the external storage device can be directly injected into the oil storage tank, which simplifies the oil filling process, reduces downtime, and improves the continuity of equipment operation. The threaded connection method of the sealing cover ensures the sealing of the oil filling pipe, prevents the leakage of lubricating oil, and reduces maintenance costs and environmental pollution.

Then, the lubricating oil stored in the storage device will enter the oil storage tank 4 through the oil filling pipe 25 and the oil filling port 24. After adding, the external storage device is removed, and then the sealing cap 26 is tightened onto the oil filling pipe 25 to achieve re-sealing of the oil filling pipe 25 to prevent leakage of the lubricating oil.

[0041] In summary, when the overall device is in use or running: when the gear 1 is rotating, the teeth of the meshing gear 1 will press against the push rod 6, so that the push rod 6 drives the sealing plate 7 to move inward, and then the sealing plate 7 drives the rubber block 22 to disengage from the sealing groove 23, and at the same time, the sealing plate 7 and the threaded plate 13 cooperate to squeeze the push spring 20 sleeved on the outside of the limiting rod 14, and then the sealing plate 7 will drive the limiting rod 14 and the screw 17 to move, and then the screw 17 will drive the push block 3 to move.
