[0026] Example: Figure 1-6As shown, the utility model provides a durability enhancement device for a rotary mechanism, comprising a fixed plate 1, a small gear 11 is rotatably provided on the upper surface of the fixed plate 1, a large gear 12 is meshed on one side of the small gear 11, and the large gear 12 is rotatably arranged on the upper surface of the fixed plate 1, a U-shaped plate 2 is fixedly provided on the upper surface of the fixed plate 1, a rotating disk 21 is fixedly provided on the upper surface of the small gear 11, a spring 22 is fixedly provided on the top lower surface of the U-shaped plate 2, a moving plate 23 is fixedly provided on the bottom end of the spring 22, a moving rod 24 is fixedly provided on the lower surface of the moving plate 23, a groove 25 is provided on the top of the rotating disk 21, and the groove 25 is used in conjunction with the moving rod 24. A liquid storage cylinder 27 is provided directly below the movable plate 23, and a sponge 28 is provided in the liquid storage cylinder 27. A push plate 29 is slidably provided in the liquid storage cylinder 27, and a push rod 26 is fixedly provided on the upper surface of the push plate 29. The top of the push rod 26 slides through the top of the liquid storage cylinder 27 and is placed outside. The top of the push rod 26 is fixedly installed on the lower surface of the movable plate 23. A liquid inlet pipe 20 is fixedly inserted on one side of the liquid storage cylinder 27, and one end of the liquid inlet pipe 20 away from the liquid storage cylinder 27 is fixedly inserted through the top of the U-shaped plate 2. When the pinion 11 and the large gear 12 need to be rotated, the lubricating oil is firstly continuously and slowly transmitted to the sponge 28 in the liquid storage cylinder 27 through the liquid inlet pipe 20. When the pinion 11 rotates, the pinion 11 drives the pinion 11 to rotate. The rotating disk 21 rotates, and the rotating disk 21 drives the groove 25 to rotate. When the groove 25 rotates to the position of the moving rod 24, the spring 22 is deformed. Under the action of the elastic force of the spring 22, the bottom of the moving rod 24 moves downward into the groove 25, and the moving rod 24 drives the moving plate 23 to move downward. The moving plate 23 drives the push rod 26 to move downward, and the push rod 26 drives the push plate 29 to move downward. In the process of the push plate 29 moving downward, the sponge 28 is compressed, and the lubricating oil in the sponge 28 flows into the meshing part between the small gear 11 and the large gear 12 through the liquid outlet at the bottom of the liquid storage cylinder 27. When the rotating disk 21 drives the groove 25 to leave the position of the moving rod 24, the moving rod 24 moves upward, and the moving rod 2 4 drives the moving plate 23 to move upward, and the spring 22 is deformed again at this time, and the moving plate 23 drives the push rod 26 and the push plate 29 to move upward. By arranging the U-shaped plate 2, the rotating disk 21, the spring 22, the moving plate 23, the moving rod 24, the groove 25, the push rod 26, the liquid storage cylinder 27, the sponge 28, and the push plate 29, the effect of continuously injecting oil to the meshing part of the small gear 11 and the large gear 12 is achieved. When in use, the meshing part of the small gear 11 and the large gear 12 is continuously injected with oil by controlling the push plate 29 to move intermittently, thereby avoiding the abnormal sound generated by the meshing part of the small gear 11 and the large gear 12 due to lack of lubricating oil, and prolonging the service life of the small gear 11 and the large gear 12.
[0027] A lower liquid nozzle 3 is fixedly penetrated in the fixed plate 1, and a lower liquid pipe 31 is fixedly provided at the bottom end of the lower liquid nozzle 3, and a liquid storage tank 32 is fixedly provided at the end of the lower liquid pipe 31 away from the lower liquid nozzle 3; when oiling the meshing point of the small gear 11 and the large gear 12, excess lubricating oil at the meshing point of the small gear 11 and the large gear 12 will flow into the lower liquid nozzle 3, and the lubricating oil in the lower liquid nozzle 3 will flow into the liquid storage tank 32 through the lower liquid pipe 31. By providing the lower liquid nozzle 3, the lower liquid pipe 31 and the liquid storage tank 32, the effect of collecting the lubricating oil is achieved, thereby avoiding a large amount of lubricating oil waste when continuously oiling the meshing point of the small gear 11 and the large gear 12, thereby greatly reducing the cost of use.
[0028] The pinion 11 is provided with a protection frame 33 outside the large gear 12, and the bottom end of the protection frame 33 is fixedly mounted on the upper surface of the fixing plate 1; by providing the protection frame 33, a large amount of lubricating oil can be prevented from being lost.
[0029] The outer fixed sleeve of the liquid storage cylinder 27 is provided with a stabilizing plate 210, and the two ends of the stabilizing plate 210 are fixedly mounted on the side of the U-shaped plate 2 close to each other; by providing the stabilizing plate 210, the effect of fixing the liquid storage cylinder 27 is achieved.
[0030] A symmetrically distributed limiting plate 220 is fixedly provided on the top lower surface of the U-shaped plate 2, and the two ends of the movable plate 23 are slidably installed on the side close to each other with the limiting plate 220; by setting the limiting plate 220, the effect of limiting the movable plate 23 is achieved, so that the movable plate 23 can move stably.
[0031] The limiting grooves 230 are provided on the sides of the limiting plates 220 that are close to each other, and the two ends of the movable plate 23 are slidably arranged in the limiting grooves 230; by providing the limiting grooves 230, the movable plate 23 can move more stably.
[0032] The lower liquid nozzle 3 is located directly below the meshing position of the pinion 11 and the large gear 12; by locating the lower liquid nozzle 3 directly below the meshing position of the pinion 11 and the large gear 12, the lubricating oil can be collected more quickly.
[0033] Working principle: First, when it is necessary to rotate the small gear 11 and the large gear 12, the lubricating oil is first slowly and continuously transferred to the sponge 28 in the liquid storage cylinder 27 through the liquid inlet pipe 20. When the small gear 11 rotates, the small gear 11 drives the turntable 21 to rotate, and the turntable 21 drives the groove 25 to rotate. When the groove 25 rotates to the position of the moving rod 24, the spring 22 is deformed. Under the action of the elastic force of the spring 22, the bottom of the moving rod 24 moves downward into the groove 25, and the moving rod 24 drives the moving plate 23 to move downward, and the moving plate 23 drives the push rod 26 to move downward, and the push rod 26 drives the push plate 29 to move downward. In the process of the push plate 29 moving downward, the sponge 28 is compressed, and the lubricating oil in the sponge 28 flows into the meshing part between the small gear 11 and the large gear 12 through the liquid outlet at the bottom of the liquid storage cylinder 27. When the turntable 21 drives the groove 25 to leave the position of the moving rod 24, the moving rod 24 moves upward, and the moving rod 24 drives the moving plate 23 to move upward. At this time, the spring 22 is deformed again, and the moving plate 23 drives the push rod 26 and the push plate 29 to move upward. By setting the U-shaped plate 2, the turntable 21, the spring 22, the moving plate 23, the moving rod 24, the groove 25, the push rod 26, the liquid storage cylinder 27, the sponge 28, and the push plate 29, the effect of continuously injecting oil to the meshing part of the small gear 11 and the large gear 12 is achieved. When in use, the meshing part of the small gear 11 and the large gear 12 is continuously injected with oil by controlling the push plate 29 to move intermittently, thereby avoiding the abnormal sound caused by the lack of lubricating oil at the meshing part of the small gear 11 and the large gear 12, thereby improving the service life of the small gear 11 and the large gear 12;
[0034] Subsequently, when oil is injected into the meshing portion of the small gear 11 and the large gear 12, excess lubricating oil at the meshing portion of the small gear 11 and the large gear 12 will flow into the lower liquid nozzle 3, and the lubricating oil in the lower liquid nozzle 3 will flow into the liquid storage tank 32 through the lower liquid pipe 31. By providing the lower liquid nozzle 3, the lower liquid pipe 31, and the liquid storage tank 32, the effect of collecting the lubricating oil is achieved, thereby avoiding a large amount of lubricating oil waste when continuously oiling the meshing portion of the small gear 11 and the large gear 12, thereby greatly reducing the cost of use.
