Technical Field

[0001] The utility model belongs to the technical field of gears, and in particular relates to a wear-resistant industrial gear. Background Art

[0002] Industrial gears are key components widely used in various industrial equipment. They transmit power and torque through the meshing of gear teeth to achieve the normal operation of the equipment. They have the characteristics of strong load-bearing capacity, high transmission efficiency and long service life. They are important components that are indispensable to ensure the smooth and efficient operation of industrial machinery.

[0003] Existing industrial gears generally lack automatic lubrication function, which may lead to insufficient lubrication of the gears during long-term operation. Due to insufficient lubrication, the friction between the gears increases, which in turn aggravates the wear of the gears and shortens their service life. In addition, manual lubrication is not only inefficient, but also difficult to ensure the uniformity and continuity of lubrication, which affects the stability and reliability of industrial equipment to a certain extent. Improvements are needed in this regard. To this end, a wear-resistant industrial gear is proposed. Utility Model Content

A piston is fixedly installed at one end of the movable rod away from the movable block, and the piston is slidably arranged on the oil pipe.

[0006] Preferably, a limit ring is fixedly installed in the oil pipe, the movable rod is slidably arranged on the limit ring, and the limit ring is provided with evenly distributed through holes.

[0017] 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 of 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.

[0018] See also Figure 1-4 , the utility model provides a technical solution:

[0019] A wear-resistant industrial gear comprises a wheel body 1 and gear teeth 2, wherein an oil storage tank 3 is arranged in the wheel body 1, and uniformly distributed and symmetrical oil pipes 4 are arranged on the wheel body 1, and the oil pipes 4 are connected with the oil storage tank 3, and a movable rod 5 is slidably arranged in the oil pipe 4, and a movable block 6 fixedly installed with the end of the movable rod 5 is arranged at the mouth of the oil pipe 4, and a spring 7 is fixedly installed in the oil pipe 4, and the spring 7 is pressed between the oil pipe 4 and the movable block 6, and a piston 8 is fixedly installed at the end of the movable rod 5 away from the movable block 6, and the piston 8 is slidably arranged on the oil pipe 4.

[0020] Lubricating oil is stored in the oil storage tank 3 arranged in the wheel body 1. When the gear is running, the gear teeth 2 will be meshed with other gears to squeeze the movable block 6. The movable block 6 drives the movable rod 5 to slide in the oil pipe 4, and the movable rod 5 then pushes the piston 8 to move. At this time, the spring 7 is compressed, and the piston 8 moves away from the oil pipe 4, which will open the pipe opening at the oil inlet of the oil pipe 4. Since the oil pipe 4 is connected to the oil storage tank 3, the lubricating oil will automatically enter the oil pipe 4. When the movable block 6 is not squeezed during the rotation of the gear, the movable rod 5 is reset by the restoring force of the spring 7, and the movable rod 5 pulls the piston 8 to re-enter the oil pipe 4. In the process of the piston 8 re-entering the oil pipe 4, the lubricating oil is pushed out of the oil pipe 4, thereby realizing the lubrication of the gear. This can ensure the continuous and stable lubrication effect of the gear, thereby effectively improving the wear resistance of the gear and having strong practicality.

[0021] A limit ring 9 is fixedly installed in the oil pipe 4, and the movable rod 5 is slidably arranged on the limit ring 9. The limit ring 9 is provided with evenly distributed through holes 10, and the limit ring 9 is provided with valves 11 in the through holes 10;

[0022] When the movable rod 5 slides in the oil pipe 4, it will pass through the limit ring 9 fixedly installed in the oil pipe 4. The movable rod 5 slides on the limit ring 9, which helps to improve the stability of the movable rod 5 when sliding. The limit ring 9 is provided with evenly distributed through holes 10, and valves 11 are provided in the through holes 10. When the movable rod 5 drives the piston 8 to move, the lubricating oil will push open the valve 11 and flow out of the through hole 10 for lubrication. When the pressure decreases, the valve 11 will close under its own elasticity to prevent the lubricating oil from flowing back, thereby ensuring continuous and stable lubrication.

[0023] A limit plate 12 is fixedly installed at one end of the movable rod 5 close to the piston 8. The limit plate 12 is arranged in an arc shape, and a sealing rubber frame 13 is arranged on the surface of the limit plate 12.

[0024] A limit plate 12 is fixedly installed at one end of the movable rod 5 near the piston 8. When the piston 8 moves, the limit plate 12 can play a certain limiting role to prevent the piston 8 from excessive movement. The limit plate 12 is arranged in an arc shape, and a sealing rubber frame 13 is arranged on the surface, which can better fit the inner wall of the oil storage tank 3.

[0025] Working principle:

[0026] The oil storage tank 3 arranged in the wheel body 1 stores lubricating oil. When the gear is running, the gear teeth 2 will be meshed with other gears to squeeze the movable block 6, and the movable block 6 will drive the movable rod 5 to slide in the oil pipe 4, and the movable rod 5 will then push the piston 8 to move. At this time, the spring 7 is compressed, and the piston 8 moves away from the oil pipe 4, which will open the pipe opening at the oil inlet of the oil pipe 4. Since the oil pipe 4 is connected to the oil storage tank 3, the lubricating oil will automatically enter the oil pipe 4. When the movable block 6 is not squeezed during the rotation of the gear, the restoring force of the spring 7 drives the movable rod 5 to reset, and the movable rod 5 pulls the piston 8 to re-enter the oil pipe 4. During the process of the piston 8 re-entering the oil pipe 4, the lubricating oil is pushed out of the oil pipe 4, thereby achieving gear lubrication, which can ensure the continuous and stable lubrication effect of the gear, thereby effectively improving the wear resistance of the gear, and has strong practicality.

[0027] When the movable rod 5 slides in the oil pipe 4, it will pass through the limit ring 9 fixedly installed in the oil pipe 4. The movable rod 5 slides on the limit ring 9, which helps to improve the stability of the movable rod 5 when sliding. The limit ring 9 is provided with evenly distributed through holes 10, and valves 11 are provided in the through holes 10. When the movable rod 5 drives the piston 8 to move, the lubricating oil will push open the valve 11 and flow out of the through hole 10 for lubrication. When the pressure is reduced, the valve 11 will close under its own elasticity to prevent the lubricating oil from flowing back, thereby ensuring continuous and stable lubrication.

[0028] A limit plate 12 is fixedly installed at one end of the movable rod 5 near the piston 8. When the piston 8 moves, the limit plate 12 can play a certain limiting role to prevent the piston 8 from excessive movement. The limit plate 12 is arranged in an arc shape, and a sealing rubber frame 13 is arranged on the surface, which can better fit the inner wall of the oil storage tank 3.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
