The existing gear box is usually filled with lubricating oil in the inner cavity to reduce the friction and wear between the gears, and also plays the role of cooling, rust prevention and corrosion resistance.

[0003] However, during the operation of the gear box, the lubricating oil between the gears is not evenly distributed, especially when the gear box vibrates or tilts, which is prone to local lubrication deficiency and other situations, thereby aggravating the gear wear and affecting the reliability and service life of the gear box.

The lubricating system works together through the base, the support structure, the oil pan and the oil conveying structure to uniformly distribute the lubricating oil in the gear box, ensuring that good lubrication effect can be achieved even under the condition of vibration or tilting.

[0012] The support structure is composed of a plurality of elastic members, which not only can effectively buffer the impact caused by vibration or tilting, but also can adapt to the change of the internal space of the gear box through the stretching and contraction of the oil pan, ensuring the continuous and stable supply of lubricating oil.

[0013] The oil pan is designed with a buffer and a connecting rope, which can swing flexibly when the impact force is large, further reducing wear and tear. The oil pan is divided into multiple oil holding parts by a partition and a flow guide opening, and the lubricating oil is uniformly delivered to the gear by the oil delivery pump, ensuring that the lubricating oil can fully cover the surface of the gear, reducing the problem of insufficient local lubrication.

[0014] The lubricating system has the above design features, which can effectively protect the gear during operation of the wind turbine generator.

[0043] The specific embodiments of the present application have been shown in the above drawings, and will be described in more detail hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0044] As the background, the gearbox is a key component in the wind turbine generator system, and its main function is to transmit the power generated by the wind wheel to the generator and to achieve the required speed of the generator through speed change. In order to reduce the friction and wear between gears, the gearbox is usually filled with lubricating oil in the inner cavity, which also plays the role of cooling, rust prevention and corrosion resistance.

[0045] However, in the actual operation process of the gearbox, the distribution of lubricating oil is often uneven, especially in the case of high-speed operation and severe vibration, the gearbox is prone to vibration or tilting, and the lubricating oil may concentrate in some areas due to the influence of gravity or centrifugal force, while in other areas, the phenomenon of oil film deficiency may occur, which is prone to local lubrication deficiency. This uneven lubrication state will cause the gear to wear out, and may also cause a series of mechanical failures, seriously affecting the overall operation efficiency and safety of the wind turbine generator system.

[0046] In order to solve the above problems, the embodiments of the present application provide a lubrication system, a gearbox and a wind turbine, which comprises a base, a support structure, an oil pan, an oil delivery structure and other components.

[0047] This lubrication system can effectively improve the lubrication condition of the gearbox in the wind turbine generator system and improve its reliability and service life. The lubrication system works together through the base, the support structure, the oil pan and the oil delivery structure to evenly distribute the lubricating oil in the gearbox, ensuring good lubrication effect even under the condition of vibration or tilting.

[0048] The support structure is composed of multiple elastic members, which not only can effectively buffer the impact caused by vibration or tilting, but also can adapt to the change of the internal space of the gearbox through the expansion of the oil pan, ensuring the continuous and stable supply of lubricating oil.

[0049] The oil pan is designed with a buffer and a connecting rope, which can swing flexibly when the impact force is large, further reducing wear and tear. The oil pan is divided into multiple oil holding parts by a partition and a flow guide, and the lubricating oil is uniformly delivered to the gear by the oil pump, ensuring that the lubricating oil can fully cover the surface of the gear, reducing the problem of insufficient local lubrication.

[0050] The lubricating system has the above design features, which can effectively protect the gear during operation of the wind turbine generator set.

[0051] When the gear is working, even if it encounters vibration or tilting conditions, this set of devices can still make the lubricating oil evenly distributed at each key position of the gear through the cooperation of the elastic member and the partition. In addition, due to the flexibility and automation level of the above design, the device also improves the operation stability and efficiency of the entire wind turbine generator set, which helps to improve the overall performance of wind power generation.

[0052] It is easy to understand that compared with the lubrication method of filling lubricating oil in the inner cavity of the gear box in the related art, the present application can effectively improve the uniformity of the distribution of lubricating oil in the gear box, reduce the wear of the gear, and thus improve the operation stability and life of the gear box.

[0059] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments.

[0060] Referring to Figures 3 to 5 The lubrication system provided by the embodiments of the present application can include a base 200, a support structure 300, an oil pan 400 and an oil delivery structure 500.

[0061] The base 200 can serve as a support and fixing part of the entire lubrication system, ensuring the installation and connection of related components, and providing stable support for the lubrication system.

[0062] The base 200 can be connected to the box body of the gear box 111 or other fixed structures by bolts, welding or other connection methods, to ensure that the lubrication system is closely combined with the main structure of the gear box 111.

[0063] The base 200 can be made of high-strength steel material to ensure that it has sufficient rigidity and strength to withstand the weight of the lubrication system and the vibration and impact generated during the operation of the gear box 111.

[0064] The base 200 can be in the shape of a rectangular flat plate, which is simple and easy to process, and can provide a large installation area, facilitating the arrangement and connection of components of the lubrication system. The rectangular design also facilitates the docking and fixing of the base 200 with the box body of the gear box 111.

[0065] The surface of the base 200 can be treated with anti-rust to ensure that it does not corrode in a lubricating oil environment for a long time.

[0066] As shown in Figure 3 The support structure 300 can include a plurality of elastic members 310. The first end of the elastic member 310 can be provided on the base 200, and the second end of the elastic member 310 can be provided as a telescopic free end that can be telescoped in the direction of approaching or moving away from the base 200. It can be ensured that the elastic member 310 can adaptively adjust the length according to the vibration amplitude of the gear box 111, thereby absorbing vibration and impact.

[0067] The main function of the elastic member 310 is to support the oil pan 400 and absorb the vibration and impact generated during the operation of the gear box 111, so as to ensure that the oil pan 400 can move smoothly, thereby maintaining the uniform distribution of lubricating oil.

[0068] A plurality of elastic members 310 can be arranged in sequence along the circumference of the oil pan 400, forming a uniformly distributed support structure 300, which can uniformly bear the force during vibration, avoiding deformation or damage caused by excessive local stress, so as to ensure the stability and reliability of the oil pan 400. For example, four elastic members 310 can be uniformly distributed at the four quadrant positions of the oil pan 400, and the included angle between each elastic member 310 is 90 degrees, so that the force on the oil pan 400 during vibration can be evenly distributed, avoiding tilting or deviation.

[0069] The elastic member 310 can be a spiral spring. The first end of the spiral spring can be welded on the four corners of the base 200, the second end of the spiral spring can be connected with the oil pan 400, and the length of the spiral spring can be adjusted according to the vibration amplitude of the gear box 111, so as to ensure that the oil pan 400 can move up and down with the vibration.

[0070] The oil pan 400 can be located at the end of the support structure 300 and connected with the base 200 through a plurality of elastic members 310. It can be ensured that the oil pan 400 can move up and down with the telescoping of the elastic member 310, thereby adapting to the vibration of the gear box 111 and the change of the amount of lubricating oil.

[0071] The oil pan 400 is mainly used to receive lubricating oil from gears or equipment, and can adjust its shape and size according to the change of the amount of lubricating oil to adapt to different use requirements.

[0072] The oil pan 400 can be made of high-strength aluminum alloy or engineering plastic to ensure lightweight and corrosion resistance.

[0073] Specifically, the oil pan 400 can be provided at the second end of the plurality of elastic members 310. The edge of the oil pan 400 can be connected with the second end of the elastic member 310 through a bolt, so as to ensure that it can stably receive lubricating oil in a vibrating state.

[0074] The oil pan 400 can be provided with a buffer 420. The buffer 420 can be a rubber block, a metal block, or the like. The buffer 420 is used to absorb the vibration and impact generated during the operation of the gearbox 111, reduce the impact on the oil pan 400, and ensure uniform distribution of the lubricating oil.

[0075] The buffer 420 can be provided with a connecting rope 430. The buffer 420 can be suspended below the oil pan 400 by the connecting rope 430. The length of the connecting rope 430 can be adjusted to ensure that the buffer 420 can effectively absorb the impact force when the oil pan 400 vibrates, reducing the impact on the oil pan 400. In this way, external vibrations can be effectively absorbed and shared, reducing the impact of vibrations on the oil pan 400 and improving the stability and reliability of the system.

[0076] The number of buffers 420 can be multiple. At least one buffer 420 is located inside the plurality of elastic members 310. For example, four buffers 420 are provided, two of which are located inside the elastic members 310, and the other two are located outside the elastic members 310. The inside buffer 420 is mainly used to absorb the impact caused by the vibration of the gearbox 111, and the outside buffer 420 is used to prevent the oil pan 400 from deviating when vibrating, to ensure that the lubricating system can remain stable when impacted.

[0077] The oil pan 400 can be formed with an oil tank 440. The depth and width of the oil tank 440 can be designed according to the amount of lubricating oil required by the gearbox 111.

[0078] As shown in Figure 5 The oil pan 400 can be provided with a partition 450. The partition 450 can be used to separate the oil tank 440 to form multiple oil holding portions 460. Multiple vertical or horizontal partition plates can divide the oil tank 440 into multiple independent oil holding portions 460.

[0079] When the gearbox 111 vibrates, the lubricating oil in the oil tank 440 will shake and generate impact force due to inertia. The partition 450 separates the oil tank 440 into multiple independent oil holding portions 460, limiting the large-scale flow of lubricating oil, dispersing the impact force of the lubricating oil into multiple oil holding portions 460, and avoiding the concentration of impact force in a certain area, thereby reducing the impact force of the lubricating oil on the oil pan 400 and the support structure 300 due to vibration.

[0080] The partition 450 can be provided with a flow guide 470 that can communicate between two adjacent oil holding portions 460. By connecting the two adjacent oil holding portions 460 through the flow guide 470, the sufficient supply of lubricating oil can be ensured, and the over-reliance on a particular part for lubrication can be avoided.

[0081] The flow guide hole 470 can be designed as a circle or a rectangle, and the aperture or width is designed according to the flow rate of the lubricating oil to ensure smooth flow of the lubricating oil.

[0082] When the gear box 111 vibrates, the flow guide hole 470 arranged on the partition 450 can control the flow rate and direction of the lubricating oil, further relieving the impact force of the lubricating oil due to vibration.

[0083] The oil inlet end of the oil conveying structure 500 can be in communication with the oil pan 400. The oil outlet end of the oil conveying structure 500 can be used to discharge lubricating oil to the gear. The oil conveying structure 500 can be used to convey the lubricating oil in the oil pan 400 to the lubricating parts such as gears, to ensure that the gears are fully lubricated during operation, reducing friction and wear.

[0084] The oil conveying structure 500 can include an oil conveying pump 510. The oil inlet of the oil conveying pump 510 can be in communication with one or more oil holding parts 460 in the oil pan 400, to ensure that the lubricating oil can flow smoothly into the oil conveying pump 510. In the oil holding part 460 connected with the oil conveying pump 510, the oil holding part 460 is provided with an oil outlet 461. The oil conveying pump 510 can be used to provide the power required for lubricating oil conveying, and the lubricating oil is sent to the required position by using the pressure difference. In the oil holding part 460 connected with the oil conveying pump 510, the lubricating oil flowing through part of the oil holding part 460 can be discharged through the oil outlet 461, thereby realizing automatic adjustment and efficient lubrication of the system.

[0085] Specifically, the oil inlet of the oil conveying pump 510 can be provided with an oil conveying pipeline 520, and the oil conveying pump 510 can be in communication with the oil outlet 461 through the oil conveying pipeline 520. The oil conveying pipeline 520 is a flexible rubber pipe with good flexibility and corrosion resistance, one end of which is connected with the oil inlet of the oil conveying pump 510, and the other end of which is connected with the oil outlet 461 of the oil holding part 460. The length and bending degree of the pipeline can be adjusted according to the structure of the gear box 111 to ensure smooth conveying of the lubricating oil.

[0086] The oil outlet 461 of the oil conveying pump 510 can be provided with a pipeline network 530. The pipeline network 530 can be used to convey the lubricating oil from the oil conveying pump 510 to each lubricating part of the gear box 111, to ensure that the lubricating oil can be uniformly distributed at each lubricating point.

[0087] The pipeline network 530 can include a main oil path 531 and branch oil paths 532. The input end of the main oil path 531 of the pipeline network 530 can be connected with the oil outlet 461 of the oil conveying pump 510 to ensure continuous supply of lubricating oil. The output end of the main oil path 531 of the pipeline network 530 can be connected with the input end of the branch oil path 532 of the pipeline network 530. The output end of the branch oil path 532 of the pipeline network 530 can be arranged at the key lubricating parts of the gear box 111, such as the gear meshing part, the bearing, etc.

[0088] The oil can be delivered to each contact point through the internal pipe network 530 of the gear box 111. The oil pump 510 can be installed on one side of the box body, and the lubricating oil is directly supplied to the top of the gear meshing surface through the gear tip nozzle, so that efficient lubrication is achieved.

[0089] As shown in Figure 4 The support structure 300 can be provided with a guide 320. The guide 320 can be provided through the elastic member 310. The center of the elastic member 310 is provided with a through hole, and the diameter of the through hole is slightly larger than the diameter of the guide 320, so as to ensure that the guide 320 can smoothly pass through.

[0090] The guide 320 can be a cylindrical metal rod, which passes through the center hole of the elastic member 310, so as to ensure that the elastic member 310 moves in the vertical direction during the extension and contraction process, and avoids lateral deviation or shaking.

[0091] After the guide 320 passes through the center hole of the elastic member 310, the elastic member 310 can freely extend and contract along the guide 320. The length of the guide 320 is usually less than the natural length of the elastic member 310, so as to ensure that the elastic member 310 is not limited during the extension and contraction process, and fully plays its shock-absorbing role.

[0092] The oil pan 400 can be provided with a connecting sleeve 410. The main function of the connecting sleeve 410 is to connect the oil pan 400 with the guide 320, so as to ensure that the oil pan 400 can stably move along the guide 320.

[0093] The connecting sleeve 410 can be sleeved on the outside of the guide 320, and the connecting sleeve 410 and the guide 320 are in sliding fit. The connecting sleeve 410 is usually in the form of a ring structure, and is sleeved on the outside of the guide 320. The inner diameter of the connecting sleeve 410 can be slightly larger than the outer diameter of the guide 320, and a small gap is left between the connecting sleeve 410 and the guide 320, so as to ensure smooth sliding.

[0094] The connecting sleeve 410 and the guide 320 are in sliding fit, so as to ensure that the oil pan 400 can stably move along the guide 320 during the movement process, and reduce friction and wear.

[0095] The connecting sleeve 410 can abut against the second end of the elastic member 310. It is ensured that the extension force of the elastic member 310 can be effectively transmitted to the oil pan 400. When the elastic member 310 extends and contracts, the connecting sleeve 410 transmits the force to the oil pan 400, so that the oil pan 400 can move up and down with the extension and contraction of the elastic member 310, thereby maintaining uniform distribution of the lubricating oil.

[0096] Based on the same concept, as shown in Figure 2 The embodiment of the present application also provides a gear box 111, which comprises any one of the lubricating systems.

[0097] The gear box 111 can include a box body. The box body can be used to accommodate gears.

[0098] The base 200 can be fixed at the bottom of the box body as a separate component. The base 200 can be connected to the box body by bolts or other connecting members to ensure the stability of the lubrication system.

[0099] Alternatively, the bottom of the box body can be directly designed as the base 200 of the lubrication system, that is, the bottom structure of the box body is integrated with the base 200. This design reduces the number of components, simplifies the installation process, and improves the overall structure.

[0100] The first end of the elastic member 310 is connected to the box body, ensuring that the support structure 300 of the lubrication system is closely combined with the main structure of the gear box 111. The connection mode can be welding, bolt fixing or other reliable connection mode.

[0101] Based on the same concept, as shown in Figure 1 The wind turbine 100 can include a nacelle 110, and the nacelle 110 can include any of the above gear boxes 111 or lubrication systems.
