Abstract
Description
Technical Field
[0001] This utility model relates to the field of gearbox lubrication technology, specifically to a gearbox lubrication assembly. Background Technology
[0002] Gearboxes are widely used in wind turbine generator sets and are a crucial mechanical component. Their primary function is to transmit the power generated by the wind turbine under wind conditions to the generator, enabling it to achieve the required rotational speed. Typically, the wind turbine's rotational speed is very low, far below the speed required for generator operation. Therefore, the speed increase achieved through the gearbox's gear pairs is necessary; hence, gearboxes are also called speed increasers.
[0003] Existing gearbox lubrication components lubricate the gear sets inside the gearbox by spraying lubricating fluid. However, the lubricating oil accumulates at the bottom of the gearbox after lubrication, which is inconvenient to circulate and easily leads to waste of lubricating oil. Therefore, it is necessary to improve the gearbox lubrication component to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a gearbox lubrication assembly to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a gearbox lubrication assembly, including a gearbox, a cleaning mechanism inside the gearbox, an oil storage tank fixedly installed at the bottom of the gearbox, an oil inlet pipe fixedly installed on the left side of the oil storage tank, a gear set body inside the gearbox, a fixing box fixedly installed at the bottom of the gearbox, an oil receiving hopper fixedly installed at the bottom of the gearbox, and a striking mechanism inside the oil storage tank.
[0006] Preferably, the cleaning mechanism includes a first bevel gear, which is fixedly installed on the right side of the gear set body. A second bevel gear is rotatably installed in the gearbox. A third bevel gear is fixedly installed at the bottom of the second bevel gear. A fourth bevel gear is rotatably installed inside the fixed box. An impeller is fixedly installed on the right side of the fourth bevel gear. An oil extraction tank is fixedly installed on the right side of the fixed box. An oil outlet pipe is fixedly installed on the top of the oil extraction tank. An oil spraying tank is fixedly installed at the end of the oil outlet pipe away from the oil extraction tank. An oil extraction pipe is fixedly installed inside the fixed box, and oil is delivered to the inside of the oil spraying tank through the oil outlet pipe for dripping.
[0007] Preferably, the oil injection box is fixedly installed on the inner side of the top of the gearbox, and the first bevel gear meshes with the second bevel gear, and the third bevel gear meshes with the fourth bevel gear, so that the gear set body can be lubricated during rotation.
[0008] Preferably, the impeller is rotatably installed inside the oil extraction tank, and the oil storage tank and the oil extraction tank are connected by an oil extraction pipe, through which oil is extracted from the oil storage tank.
[0009] Preferably, the striking mechanism includes a rotating shaft, which is fixedly installed on the left side of the bevel gear. A stirring rod is fixedly installed on the outside of the rotating shaft, and a fixing frame is fixedly installed on the outside of the rotating shaft. A spring is fixedly installed inside the fixing frame, and a striking rod is fixedly installed on the end of the spring away from the fixing frame. Under the action of the spring, the striking rod continuously strikes the bottom of the oil hopper to accelerate the sliding speed of the lubricating oil.
[0010] Preferably, the rotating shaft is rotatably installed inside the oil storage tank, a filter screen is fixedly installed at the bottom of the oil receiving hopper, the striking rod is slidably installed inside the fixed frame, and the stirring rod agitates the lubricating oil inside the oil storage tank.
[0011] Compared with the prior art, the present invention provides a gearbox lubrication assembly, which has the following advantages:
[0012] 1. This gearbox lubrication assembly, through its cleaning mechanism, causes the impeller to rotate inside the oil tank during use. Under centrifugal force, oil is drawn from the oil storage tank through the oil extraction pipe and delivered to the oil spraying tank through the oil outlet pipe for dripping. The oil receiving hopper is funnel-shaped, allowing the lubricating oil to pass through the filter screen and re-enter the oil storage tank more quickly, completing the circulation and spraying of the lubricating oil, reducing lubricating oil waste, and filtering impurities and contaminants from the lubricating oil through the filter screen to maintain the cleanliness of the lubricating oil.
[0013] 2. The gearbox lubrication assembly, through its set-in striking mechanism, uses a stirring rod to agitate the lubricating oil inside the oil reservoir during use, preventing the lubricating oil from settling after long-term standing and maintaining the stability of the lubricating oil. During rotation, the striking rod, under the action of a spring, continuously strikes the bottom of the oil receiving hopper, accelerating the sliding speed of the lubricating oil and thus allowing the lubricating oil to leak from the oil receiving hopper into the oil reservoir more quickly.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0022] Example 1:
[0023] Please see Figure 1-3 This utility model provides a technical solution: a gearbox lubrication assembly, including a gearbox 1, a cleaning mechanism 2 inside the gearbox 1, an oil storage tank 4 fixedly installed at the bottom of the gearbox 1, an oil inlet pipe 5 fixedly installed on the left side of the oil storage tank 4, a gear set body 7 inside the gearbox 1, a fixing box 6 fixedly installed at the bottom of the gearbox 1, an oil receiving hopper 8 fixedly installed at the bottom of the gearbox 1, and a striking mechanism 3 inside the oil storage tank 4.
[0024] Furthermore, the cleaning mechanism 2 includes a bevel gear 21, which is fixedly installed on the right side of the gear set body 7. A bevel gear 22 is rotatably installed in the gearbox 1. A bevel gear 3 23 is fixedly installed at the bottom of the bevel gear 22. A bevel gear 4 24 is rotatably installed inside the fixed box 6. An impeller 25 is fixedly installed on the right side of the bevel gear 4 24. An oil extraction tank 26 is fixedly installed on the right side of the fixed box 6. An oil outlet pipe 27 is fixedly installed on the top of the oil extraction tank 26. An oil spray tank 28 is fixedly installed at the end of the oil outlet pipe 27 away from the oil extraction tank 26. An oil extraction pipe 29 is fixedly installed inside the fixed box 6. The oil is delivered to the inside of the oil spray tank 28 through the oil outlet pipe 27 and dripped.
[0025] Furthermore, the oil injection tank 28 is fixedly installed on the inner side of the top of the gearbox 1, and the first bevel gear 21 meshes with the second bevel gear 22, and the third bevel gear 23 meshes with the fourth bevel gear 24, so that the gear set body 7 can be lubricated during rotation.
[0026] Furthermore, the impeller 25 is rotatably installed inside the oil tank 26, and the oil storage tank 4 and the oil tank 26 are connected by an oil extraction pipe 29, through which oil is extracted from the oil storage tank 4.
[0027] Example 2:
[0028] Please see Figure 4 Furthermore, in conjunction with Embodiment 1, it is further found that the striking mechanism 3 includes a rotating shaft 31, which is fixedly installed on the left side of the bevel gear 24. A stirring rod 32 is fixedly installed on the outside of the rotating shaft 31, and a fixing frame 33 is fixedly installed on the outside of the rotating shaft 31. A spring 34 is fixedly installed inside the fixing frame 33. A striking rod 35 is fixedly installed at the end of the spring 34 away from the fixing frame 33. Under the action of the spring 34, the striking rod 35 continuously strikes the bottom of the oil hopper 8 to accelerate the sliding speed of the lubricating oil.
[0029] Furthermore, the rotating shaft 31 is rotatably installed inside the oil storage tank 4, a filter screen is fixedly installed at the bottom of the oil receiving hopper 8, the striking rod 35 is slidably installed inside the fixed frame 33, and the stirring rod 32 stirs the lubricating oil inside the oil storage tank 4.
[0030] In actual operation, when this device is in use, lubricating oil is placed inside the oil storage tank 4 through the oil inlet pipe 5, and then transported to the oil extraction tank 26 through the oil extraction pipe 29. When the gear set body 7 is started, the gear set body 7 rotates, driving the first bevel gear 21 to rotate. The rotation of the first bevel gear 21 drives the second bevel gear 22, which in turn drives the third bevel gear 23, which in turn drives the fourth bevel gear 24, which in turn causes the impeller 25 to rotate inside the oil extraction tank 26. Under the rotation of centrifugal force, the oil inside the oil storage tank 4 is extracted through the oil extraction pipe 29 and transported to the oil spray tank 28 through the oil outlet pipe 27 for dripping. After the lubricating oil drips onto the surface of the gear set body 7, it falls into the receiving tank. Inside the oil hopper 8, because the oil hopper 8 is funnel-shaped, the lubricating oil can pass through the filter screen more quickly and re-enter the oil storage tank 4, completing the circulation and spraying of the lubricating oil, reducing the waste of lubricating oil, and filtering impurities and contaminants in the lubricating oil through the filter screen to maintain the cleanliness of the lubricating oil. While the bevel gear 4 24 rotates, it drives the rotating shaft 31 to rotate, causing the stirring rod 32 to stir the lubricating oil inside the oil storage tank 4, preventing the lubricating oil from settling after long-term standing and maintaining the stability of the lubricating oil. During the rotation, the striking rod 35 continuously strikes the bottom of the oil hopper 8 under the action of the spring 34, accelerating the sliding speed of the lubricating oil, and thus making the lubricating oil leak from the oil hopper 8 into the oil storage tank 4 more quickly.
