Description

Technical Field

[0001] The utility model relates to the technical field of gearboxes, and more specifically, to a lubrication system for a new type of micro-wind power speed increaser. Background Art

[0002] The micro-wind power speed increaser is mainly applicable to the field of micro-wind power generation. The micro-wind power speed increaser is a kind of gearbox, and its internal transmission components need to be lubricated and cooled during operation. The existing lubrication structures of micro-wind power speed increasers have at least the following disadvantages:

[0003] 1. Most lubrication methods adopt oil immersion lubrication, and the oil passage holes are simply designed, resulting in insufficient cooling and lubrication of the internal parts of the speed increaser;

[0004] 2. The oil injection position is high. During the operation of the speed increaser, the oil agitation loss inside the gearbox increases, reducing the transmission and lubrication efficiency;

[0005] 3. The oil seal is immersed in the lubricating oil for a long time, resulting in a short service life of the oil seal and easy leakage;

[0006] 4. The lubricating transmission has a large amount of agitated oil. Especially in a low-temperature environment, a large amount of lubricating oil will cause a large lubrication loss, resulting in low transmission efficiency. Summary of the Utility Model

[0007] The purpose of the utility model includes providing a lubrication system for a new type of micro-wind power speed increaser, which can reduce the oil agitation loss, lower the maintenance cost, and improve the transmission efficiency.

[0008] The embodiments of the utility model can be implemented as follows:

[0009] In a first aspect, the utility model provides a lubrication system for a new type of micro-wind power speed increaser, including:

[0010] A housing, an input shaft, a transmission mechanism, an output shaft, and an output end oil seal. The input shaft and the output shaft are rotatably installed in the housing, and the input shaft is connected to the output shaft through the transmission mechanism; the output end oil seal is connected to both the housing and the output shaft at the same time; a main oil pool is arranged inside the housing, and the oil injection liquid level of the main oil pool is lower than the output end oil seal; an oil collecting cavity is arranged on the inner wall surface of the housing, and the oil collecting cavity is used for collecting the lubricating oil liquid splashed by the agitation of the transmission mechanism and guiding the lubricating oil liquid to the position to be lubricated.

[0011] In an optional embodiment, the oil collecting cavity includes an oil collecting groove and a drain hole. The cross-sectional area of the oil collecting groove is larger than that of the drain hole, and the drain hole communicates with the oil collecting groove from the bottom of the oil collecting groove; it is used for collecting the lubricating oil liquid splashed by the agitation of the transmission mechanism and guiding the lubricating oil liquid to the position to be lubricated through the drain hole.

[0012] Based on the above solution, the structure of the oil collecting cavity is simple, and the volume of the oil collecting groove is large, which can collect more lubricating oil. When the lubricating oil is guided from the oil discharge hole with a smaller inner diameter to the position to be lubricated, the flow rate of the lubricating oil in the oil discharge hole slows down, prolonging the time for the lubricating oil to stay in the oil collecting groove, extending the lubrication time, and meeting the lubrication requirements of the transmission components.

[0013] In an alternative embodiment, the transmission mechanism includes a low-speed transmission unit and a high-speed transmission unit. The input shaft is connected to the low-speed transmission unit, the low-speed transmission unit is connected to the high-speed transmission unit, and the high-speed transmission unit is connected to the output shaft. The number of the oil collecting cavities is two, and the two oil collecting cavities are used to guide the lubricating oil to the low-speed transmission unit and the high-speed transmission unit respectively.

[0014] Based on the above solution, by guiding the lubricating oil to the corresponding positions through two oil collecting cavities respectively, the lubrication area can be increased, fixed-point lubrication can be realized, and the lubrication effect and lubrication efficiency can be improved.

[0015] In an alternative embodiment, the housing includes a front housing, an intermediate housing, and a rear housing connected in sequence. The front housing and the intermediate housing cooperate to define a first oil sump, the intermediate housing and the rear housing cooperate to define a second oil sump, and the first oil sump and the second oil sump communicate to form the main oil sump. The input shaft is rotatably installed in the rear housing, and the output shaft is rotatably installed in the front housing.

[0016] Based on the above solution, the main oil sump is divided into a first oil sump and a second oil sump by the intermediate housing. The first oil sump and the second oil sump communicate with each other, and the utilization rate of the lubricating oil is high. Moreover, the lubricating oil in the first oil sump corresponds to the high-speed transmission unit. Under the agitation of the transmission components of the high-speed transmission unit, the lubricating oil can splash-lubricate the relevant components of the high-speed transmission unit, improving the problem that the high-speed end oil seal is prone to oil leakage while meeting the lubrication effect. The lubricating oil in the second oil sump corresponds to the low-speed transmission unit. The rotation speed of the low-speed transmission unit is low, and the amount of agitated lubricating oil is small. The lubricating oil in the second oil sump mainly lubricates the relevant components of the low-speed transmission unit by immersion lubrication.

[0017] In an alternative embodiment, an oil collecting cavity is provided on the inner side wall of the front housing, and an oil collecting cavity is provided on the inner side wall of the intermediate housing close to the front housing.

[0018] Based on the above solution, the lubricating oil can be accurately guided to the set position through the oil collecting cavities at different positions, and the lubrication effect is good.

[0019] In an alternative embodiment, an oil return hole communicating with the first oil sump is provided on the inner side wall of the front housing; an oil return hole communicating with the second oil sump is provided on the inner side wall of the intermediate housing.

[0020] Based on the above solution, during the stirring process, the lubricating oil is conveyed above the housing. Part of the lubricating oil enters the oil collecting chamber, and part of the lubricating oil can directly fall under the action of gravity. During the falling process, the lubricating oil lubricates the transmission components along the way. The lubricating oil also returns to the corresponding oil sump through the oil return hole at the bottom, facilitating participation in the next lubrication.

[0021] In an alternative embodiment, a through hole is provided at the bottom of the intermediate housing, and the first oil sump and the second oil sump are communicated through the through hole.

[0022] Based on the above solution, the connection mode between the first oil sump and the second oil sump is simple, which is convenient for processing and manufacturing.

[0023] In an alternative embodiment, the low-speed transmission unit includes a first planet carrier, a first planet gear, a first sun gear, and a first ring gear; the first planet carrier is connected to the input shaft, the first planet gear is rotatably mounted on the first planet carrier, the first sun gear is rotatably mounted on the housing; the first ring gear is fixed to the housing, and the first planet gear meshes with both the first sun gear and the first ring gear; the first sun gear is connected to the high-speed transmission unit.

[0024] Based on the above solution, the low-speed transmission unit is a planetary transmission structure, which is compact in structure, high in transmission efficiency, and stable and reliable in operation.

[0025] In an alternative embodiment, the high-speed transmission unit includes a second planet carrier, a second planet gear, a second sun gear, and a second ring gear; the second planet carrier is rotatably matched with the housing, the second planet carrier is connected to the first sun gear and rotates synchronously with it; the second planet gear is rotatably mounted on the second planet carrier, the second sun gear is rotatably mounted on the housing and is fixedly connected to the output shaft; the second ring gear is fixed to the housing, and the second planet gear meshes with both the second sun gear and the second ring gear.

[0026] Based on the above solution, the high-speed transmission unit is a planetary transmission structure, which is compact in structure, high in transmission efficiency, and stable and reliable in operation.

[0027] In an alternative embodiment, a pin shaft is installed on the second planet carrier, the second planet gear is rotatably matched with the second planet carrier through the pin shaft, and an axially communicating oil collecting hole and a radially communicating oil outlet hole are provided on the pin shaft. The axially communicating oil collecting hole is used to collect the lubricating oil and flow out through the radially communicating oil outlet hole.

[0028] Based on the above solution, the lubricating oil splashes into the axial oil collecting hole under the agitation of the transmission components and then discharges from the radial oil outlet hole, which can effectively lubricate the transmission components at the position where the second planet gear is located and improve the lubrication effect.

[0029] The beneficial effects of the novel lubrication system for a micro-wind power speed increaser provided by the embodiments of the present invention include:

[0030] In summary, for the novel lubrication system for a micro-wind power speed increaser provided by this embodiment, by controlling the oil injection liquid level of the main oil sump below the position of the high-speed end oil seal, the oil injection amount is reduced, the maintenance cost and the oil agitation loss are lowered, and the transmission efficiency is improved. At the same time, the high-speed end oil seal is not directly immersed in the lubricating oil, effectively improving the problem of easy leakage of the dynamic lip immersed in oil. Moreover, since the high-speed end oil seal is a non-immersed oil seal, it can adopt a lip structure with a low clamping force, thereby further reducing the sealing friction loss and further improving the transmission efficiency, and thus having a higher power generation efficiency and market competitiveness. It should be understood that since the main oil sump and the oil collecting cavity are provided inside the housing, the lubricating oil collects in the main oil sump. During the operation of the transmission mechanism, the lubricating oil in the main oil sump is agitated, and the lubricating oil enters the oil collecting cavity for storage and can be guided to the set position, improving the lubrication effect and efficiency and being beneficial to improving the heat dissipation of the transmission mechanism.

[0044] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0045] Please refer to Figures 1-5 , in this embodiment, the novel lubrication system for a micro-wind power speed increaser includes a housing 100, an input shaft 200, a transmission mechanism 300, an output shaft 400, and an output end oil seal. The input shaft 200 and the output shaft 400 are rotatably installed in the housing 100, and the input shaft 200 is connected to the output shaft 400 through the transmission mechanism 300; the output end oil seal is simultaneously connected to the housing 100 and the output shaft 400; a main oil sump is provided inside the housing 100, and the oil filling level of the main oil sump is lower than the output end oil seal; an oil collecting cavity is provided on the inner wall surface of the housing 100, and the oil collecting cavity is used to collect the lubricating oil splashed by the agitation of the transmission mechanism 300 and guide the lubricating oil to the position to be lubricated.

[0046] As described above, the working mode of the novel lubrication system for a micro-wind power speed increaser provided in this embodiment is as follows:

[0047] The input shaft 200 can be connected to the wind blade shaft, and the output shaft 400 can be connected to the shaft body of the generator. Under the action of wind force, the wind blade shaft drives the input shaft 200 to rotate, and after increasing the torque through the transmission mechanism 300, it is transmitted to the output shaft 400, and the shaft body of the generator is driven to rotate by the output shaft 400, and the generator uses wind power to generate electricity.

[0048] During operation, the lubricating oil is collected in the main oil sump, and the transmission mechanism 300 agitates the lubricating oil in the main oil sump. The lubricating oil enters the oil collecting cavity for storage and can be guided to the set position, improving the lubrication effect and efficiency, and being beneficial to improving the heat dissipation of the transmission mechanism 300.

[0049] Moreover, by controlling the oil filling liquid level 001 of the main oil sump below the high-speed end oil seal 500, the oil filling amount is reduced, the maintenance cost and the oil stirring loss are lowered, and the transmission efficiency is improved. At the same time, the high-speed end oil seal 500 is not directly immersed in the lubricating oil, effectively improving the problem of easy leakage of the dynamic lip immersed in oil. And since the high-speed end oil seal 500 is a non-immersed oil seal, it can adopt a lip structure with a low clamping force, thereby further reducing the sealing friction loss and further improving the transmission efficiency, and thus having a higher power generation efficiency and market competitiveness.

[0050] The following embodiments will illustrate the detailed structure of the novel lubrication system for a micro-wind power speed increaser of the present application by way of examples.

[0051] Please refer to Figure 2, in this embodiment, optionally, the housing 100 is provided with a split structure, which is convenient for processing and manufacturing, and also convenient for the installation and disassembly of other structural parts such as the transmission mechanism 300 inside the housing 100. For example, the housing 100 includes a front housing 110, an intermediate housing 120, and a rear housing 130 that are connected in sequence. The front housing 110 and the intermediate housing 120 can be connected by a flange structure, and the intermediate housing 120 and the rear housing 130 can be connected by a flange structure. The front housing 110 and the intermediate housing 120 cooperate to define a first oil sump 101, and the intermediate housing 120 and the rear housing 130 cooperate to define a second oil sump 102. The first oil sump 101 and the second oil sump 102 communicate to form a main oil sump. The input shaft 200 is rotatably mounted on the rear housing 130 through a bearing, and the output shaft 400 is rotatably mounted on the front housing 110 through a bearing. Since the rotational speed of the input shaft 200 is low, the low-speed stage of the transmission mechanism 300 cooperating with the input shaft 200 runs at a low speed, and mainly performs oil immersion lubrication through the lubricating oil in the first oil sump 101. After the output shaft 400 is accelerated, its rotational speed is high, and the high-speed stage of the transmission mechanism 300 cooperating with the output shaft 400 runs at a high speed, and mainly performs splash lubrication by agitating the lubricating oil in the second oil sump 102.

[0052] Please refer to Figure 2 and Figure 3 , optionally, a first assembly hole 111 is provided at the middle position of the front housing 110. The output shaft 400 is rotatably mounted in the first assembly hole 111 through a bearing, and the high-speed end oil seal 500 is mounted in the first assembly hole 111. A first oil collecting cavity 112 and a first oil return hole 113 are provided on the inner side wall of the front housing 110 facing the intermediate housing 120. The first oil collecting cavity 112 includes an oil collecting groove and an oil discharge hole. The cross-sectional area of the oil collecting groove is larger than that of the oil discharge hole. One end of the oil discharge hole communicates with the oil collecting groove from the bottom of the oil collecting groove, and the other end of the oil discharge hole communicates with the first assembly hole 111. One end of the first oil return hole 113 communicates with the first assembly hole 111, and the other end communicates with the first oil sump 101. The first oil return hole 113 and the first oil collecting cavity 112 are arranged at intervals in the circumferential direction of the first assembly hole 111, and the two can be located on the same diameter of the first assembly hole 111. In actual use, the first oil collecting cavity 112 is located directly above the housing 100. Correspondingly, the first oil return hole 113 is located directly below the housing 100. In this way, after the lubricating oil flows from top to bottom to lubricate the relevant components, the lubricating oil reaches the first oil return hole 113, which is convenient for the lubricating oil to quickly enter the first oil sump 101, avoiding the accumulation of lubricating oil at the position of the bearing corresponding to the output shaft 400, resulting in an increase in oil stirring loss and heat accumulation, thereby improving the transmission efficiency and reducing the temperature of the bearing at the position of the output shaft 400.

[0053] Please refer to Figure 2 and Figure 4, optionally, the intermediate housing 120 is provided with a second assembly hole 121. A second oil sump 122 is provided on the inner side wall of the intermediate housing 120 close to the front housing 110. The second oil sump 122 can be set as a stepped hole structure, using the hole section with a larger aperture to collect oil, and then using the hole section with a smaller aperture to drain oil. Or, the second oil sump 122 can be set as a tapered hole with a gradually changing aperture, etc. The second assembly hole 121 communicated with the second oil sump 122 guides the lubricating oil to the position of the bearing located in the second assembly hole 121. A second oil return hole 123 is provided on the inner side wall of the intermediate housing 120 far from the front housing 110. The second oil return hole 123 is communicated with the second oil sump 102, which has the functions of oil return and oil collection. And, a through hole 124 is provided at the bottom of the intermediate housing 120. The through hole 124 communicates the first oil sump 101 and the second oil sump 102. The through hole 124 is located directly below the housing 100. By providing the through hole 124, the lubricating oil in the first oil sump 101 is guided to the second oil sump 102, strengthening the oil immersion lubrication of the low-speed stage of the transmission mechanism 300.

[0054] Please refer to Figure 2 and Figure 4 , optionally, a third assembly hole 131 is provided in the middle of the rear housing 130. A low-speed end oil seal 600 and a bearing are provided in the third assembly hole 131. The input shaft 200 is arranged in the third assembly hole 131 and is rotatably matched with the rear housing 130.

[0055] It should be understood that after the front housing 110, the intermediate housing 120 and the rear housing 130 are connected, the first assembly hole 111, the second assembly hole 121 and the third assembly hole 131 are coaxial.

[0056] Please refer to Figure 2 , in this embodiment, optionally, the transmission mechanism 300 includes a low-speed transmission unit and a high-speed transmission unit. The input shaft 200 is connected to the low-speed transmission unit, the low-speed transmission unit is connected to the high-speed transmission unit, and the high-speed transmission unit is connected to the output shaft 400. The first oil sump 112 is used to guide the lubricating oil to the high-speed transmission unit. After lubricating the high-speed transmission unit, the lubricating oil flows back to the first oil sump 101. The second oil sump 122 is used to guide the lubricating oil to the low-speed transmission unit. After lubricating the low-speed transmission unit, the lubricating oil flows back to the second oil sump 102.

[0057] Optionally, the low-speed transmission unit includes a first planetary carrier 310, first planetary gears 320, a first sun gear 330, and a first ring gear 340. The first planetary carrier 310 is connected to the input shaft 200, and the two can be configured as an integral structure. The first planetary gears 320 are rotatably mounted on the first planetary carrier 310, and the first sun gear 330 is rotatably inserted into the second assembly hole 121. The first ring gear 340 is fixed between the intermediate housing 120 and the rear housing 130, and the three can be fixedly connected by bolts. The first planetary gears 320 mesh with both the first sun gear 330 and the first ring gear 340. The first sun gear 330 is connected to the high-speed transmission unit. It should be understood that when the input shaft 200 rotates due to the input torque from the fan shaft, the first planetary carrier 310 rotates with it, driving the first planetary gears 320 to orbit. Under the action of the first ring gear 340, the first planetary gears 320 rotate, thereby driving the first sun gear 330 to rotate, outputting torque to the high-speed transmission unit.

[0058] Optionally, the high-speed transmission unit includes a second planetary carrier 350, a second planetary gear 360, a second sun gear 370, a second ring gear 380 and a pin 390. Part of the second planetary carrier 350 is inserted into the second assembly hole 121 and rotatably cooperates with the second assembly hole 121. Part of the second planetary carrier 350 is also rotatably cooperated with the front housing 100 through a bearing. The first sun gear 330 is inserted into the second planetary carrier 350 and the two can be connected by a spline, so that the second planetary carrier 350 and the first sun gear 330 can rotate synchronously. The second planetary gear 360 is rotatably mounted on the second planetary carrier 350 by a pin 390. The second sun gear 370 is rotatably mounted in the first assembly hole 111 by a bearing and is fixedly connected to the output shaft 400. The second sun gear 370 can be set as an integrated structure with the output shaft 400. The second ring gear 380 is fixed to the intermediate housing 120, and the two can be fixedly connected by a spline structure. The second planetary gears 360 mesh with both the second sun gear 370 and the second ring gear 380. During operation, the first sun gear 330 generates torque, driving the second planetary carrier 350 to rotate. The second planetary carrier 350 then drives the second planetary gears 360 to orbit. Driven by the second ring gear 380, the second planetary gears 360 rotate, driving the second sun gear 370 to rotate, ultimately outputting torque from the output shaft 400.

[0059] It should be understood that the transmission mechanism 300 is configured as a two-stage planetary transmission structure, which has stable operation, compact structure, small size, and is easy to assemble.

[0060] Optionally, an axially connected oil collecting hole 391 and a radially extending oil outlet hole 392 are provided on the pin shaft 390. The axially connected oil collecting hole 391 is used to collect lubricating oil and flow out through the radially extending oil outlet hole 392. The axially connected oil collecting hole 391 may be a blind hole, and the orifice of the axially connected oil collecting hole 391 faces the front housing 110. The number of the radially extending oil outlet holes 392 may be multiple and arranged at intervals. The lubricating oil is splashed into the axially connected oil collecting hole 391 under the agitation of the transmission components and then discharged from the radially extending oil outlet hole 392, which can effectively lubricate the transmission components at the position of the second planet gear 360 and improve the lubrication effect.

[0061] The novel lubrication system for a micro wind power speed increaser provided in this embodiment can perform fixed-point splash lubrication on bearings at different positions of the high-speed transmission unit and adopt oil immersion lubrication for the low-speed transmission unit, with good lubrication effect. Moreover, the oil injection level of the lubricating oil in the main oil sump is controlled below the position of the high-speed end oil seal 500, reducing the amount of oil, minimizing the oil agitation loss, and improving the transmission efficiency. Also, the high-speed end oil seal 500 is not immersed in the oil, which improves the problem of easy leakage due to the dynamic lip being immersed in the oil and extends the service life of the high-speed end oil seal 500.

[0062] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
