Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a generator angle speed increaser and a power generation system. Background Art

[0002] The wind speed increaser is used in the new wind power generation field, mainly in vertical and horizontal layout. At present, the speed increaser used in vertical wind turbines has at least the following problems:

[0003] 1) Currently, all speed increasers used in vertical wind turbines are vertical speed increasers, with the generator mounted below the speed increaser. Disassembly and maintenance require additional support for the speed increaser or generator, creating maintenance inconvenience. Furthermore, a single vertical speed increaser is no longer sufficient to meet the development and application needs of new vertical wind turbines (e.g., twin-rotor vertical wind turbines).

[0004] 2) The high-speed end oil seal of the vertical speed increaser is located at the bottom of the gearbox and is an oil-immersed seal. The metal particles in the lubricating oil in the box are easily deposited on the bottom oil seal lip under the action of gravity, accelerating the wear of the lip; at the same time, the liquid level of the lubricating oil on the upper part of the oil seal is relatively high, which exerts greater pressure on the lip, further increasing the wear of the lip and reducing the service life of the oil seal.

[0005] 3) In the existing angular gearbox, the high-speed bevel gear is set at the bottom of the low-speed stage, resulting in the high-speed end oil seal being located at the bottom of the gearbox. This is also an oil-immersed seal, which is prone to leakage and failure, making it difficult to meet the long-term maintenance-free requirements of the wind power speed increaser. Utility Model Content

[0006] The purpose of the utility model includes providing a generator angular speed increaser and a power generation system, which can reduce the probability of high-speed shaft end seal failure while realizing horizontal arrangement of the generator and the speed increaser, thereby extending the service life of the speed increaser.

[0007] The embodiment of the present utility model can be implemented as follows:

[0008] In a first aspect, the present invention provides a generator angle speed increaser, comprising:

[0009] A box body, a low-speed transmission mechanism and a high-speed transmission mechanism, the input part of the low-speed transmission mechanism is used to connect with the blade shaft, the output part of the low-speed transmission mechanism is connected with the input part of the high-speed transmission mechanism, the output part of the high-speed transmission mechanism is used to connect with the generator assembly, and the rotation axes of the input part and the output part of the high-speed transmission mechanism have an angle; the output part of the high-speed transmission mechanism is located on the side of the output part of the low-speed transmission mechanism close to the blade shaft.

[0010] In an optional embodiment, the high-speed transmission mechanism includes a first bevel gear and a second bevel gear, the first bevel gear and the second bevel gear are meshed with each other and are both rotatably mounted on the housing, and the axle of the second bevel gear extends out of the housing; the output portion of the low-speed transmission mechanism is connected to the first bevel gear, and the second bevel gear is used for connection to the generator assembly.

[0011] Based on the above solution, the output of the low-speed transmission mechanism transmits torque to the first bevel gear, which then transmits the torque to the generator assembly via the second bevel gear, causing the generator assembly to operate and generate electricity. Due to the structural arrangement of the first and second bevel gears, the axle of the first bevel gear and the axle of the second bevel gear can be arranged at an angle, for example, they can be arranged perpendicularly. The axle of the second bevel gear is connected to the generator assembly, and the generator assembly can be arranged horizontally relative to the speed increaser, making the speed increaser and generator assembly very convenient to install and remove.

[0012] In an optional embodiment, the generator angular speed increaser further includes a high-speed oil seal assembly, and the high-speed oil seal assembly is installed between the housing and the axle of the second bevel gear.

[0013] Based on the above solution, the gap between the axle of the second bevel gear and the housing is sealed by a high-speed oil seal assembly to reduce the probability of oil leakage.

[0014] In an optional embodiment, the low-speed transmission mechanism includes an input shaft, a planetary carrier, a sun gear, a planetary gear and a ring gear; the input shaft is used to connect to the blade shaft, the input shaft is connected to the planetary carrier, and the planetary carrier is rotatably matched with the housing; the planetary gear is rotatably mounted on the planetary carrier, the sun gear is sleeved on the input shaft or the outside of the planetary carrier, and the sun gear is rotatably matched with the input shaft or the planetary carrier; the ring gear is fixed to the housing, the planetary gear is meshed with the ring gear and the sun gear at the same time, the sun gear is connected to the first bevel gear, and the first bevel gear is sleeved on the input shaft or the outside of the planetary carrier.

[0015] Based on this scheme, after the input shaft is connected to the blade shaft, the wind forces the blade body to rotate the blade shaft, which in turn drives the input shaft. The input shaft transmits torque to the planetary carrier, which rotates and, in conjunction with the ring gear, drives the planetary gears to rotate and orbit. The planetary gears' rotation and orbital motion drive the sun gear, which then outputs torque to the first bevel gear. Finally, the torque is transmitted to the generator assembly via the second bevel gear. Using a planetary structure for torque transmission is more stable and reliable.

[0016] In an optional embodiment, the input shaft and the planet carrier are configured as an integrated structure.

[0017] Based on the above solution, the assembly link of the input shaft and the planetary carrier is omitted, saving assembly steps.

[0018] In an optional embodiment, an assembly groove is provided on the outer side of the planet carrier, a bearing is installed in the assembly groove, the sun gear is inserted into the inner ring of the bearing, and the sun gear is rotatably matched with the planet carrier through the bearing.

[0019] Based on the above solution, the sun gear cooperates with the first bevel gear and the planet gear at the same time, and the sun gear also cooperates with the planet carrier through the bearing. The area where the sun gear is supported and positioned is large, and the stability of the sun gear during rotation is high.

[0020] In an optional embodiment, the sun gear is provided with a fixed shaft segment, a gear shaft segment and an output shaft segment arranged in sequence in its axial direction, and the output shaft segment is located on the side of the gear shaft segment close to the impeller shaft; the fixed shaft segment is inserted into the inner ring, the gear shaft segment is engaged with the planetary gear, and the output shaft segment is connected to the first bevel gear.

[0021] Based on the above solution, the bearings, planetary gears and the first bevel gear are arranged in the axial direction of the sun gear, which has a compact structure, a small volume and is easy to assemble.

[0022] In an optional embodiment, the generator angular speed increaser further includes a low-speed oil seal assembly, which is installed between the input shaft and the housing, or between the planetary carrier and the housing.

[0023] Based on the above solution, by providing a low-speed oil seal assembly, the sealing between the input part of the low-speed transmission mechanism and the box body can be ensured.

[0024] In an optional embodiment, the box is configured as a split structure.

[0025] Based on the above solution, the structure of the box is simple, and the box can be disassembled and assembled as needed, which facilitates the cooperation between the low-speed transmission mechanism and the high-speed transmission mechanism and the box.

[0026] In an optional embodiment, the box body includes a lower shell, a middle shell and an upper shell connected in sequence, and at least a portion of the upper shell is located in the area surrounded by the middle shell.

[0027] Based on the above solution, the upper shell and the middle shell fit closely together, the radial space of the middle shell is reasonably utilized, the axial size of the box is reduced, and the box structure is more compact.

When the lubricating oil is stored in the housing, the output portion of the high-speed transmission mechanism can be located above the liquid surface of the lubricating oil, or the output portion of the high-speed transmission mechanism can be partially immersed in the lubricating oil, without having to immerse the entire output portion of the high-speed transmission mechanism in the lubricating oil. The load on the sealing structure at the location of the output portion of the high-speed transmission mechanism is small, the probability of the sealing structure contacting debris in the oil is low, the probability of the sealing structure being worn and damaged is low, and the seal failure is not likely to occur. The location of the output portion of the high-speed transmission mechanism is not prone to oil leakage. In addition, the axis of the input portion and the axis of the output portion of the high-speed transmission mechanism are at an angle. The output portion of the high-speed transmission mechanism is connected to the generator assembly through the output portion of the high-speed transmission mechanism, which can enable the generator assembly and the speed increaser to be arranged horizontally, facilitating the disassembly and maintenance of the two.

[0046] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0047] Please combine Figure 1 and Figure 2 In this embodiment, the generator angle speed increaser includes a housing 100, a low-speed transmission mechanism 200, and a high-speed transmission mechanism 300. The input portion of the low-speed transmission mechanism 200 is connected to the blade shaft 001, and the output portion of the low-speed transmission mechanism 200 is connected to the input portion of the high-speed transmission mechanism 300. The output portion of the high-speed transmission mechanism 300 is connected to the generator assembly 002. The rotation axis of the input portion and the rotation axis of the output portion of the high-speed transmission mechanism 300 form an included angle. The output portion of the high-speed transmission mechanism 300 is located on the side of the output portion of the low-speed transmission mechanism 200 that is closer to the blade shaft 001.

[0048] As described above, the generator angle speed increaser provided in this embodiment works as follows:

[0049] Please combine Figure 6 The housing 100 is placed on the ground or other support. The axes of the input of the low-speed transmission mechanism 200 and the input of the high-speed transmission mechanism 300 both extend vertically. The axis of the output of the high-speed transmission mechanism 300 extends horizontally or at a certain angle to the horizontal plane. The output of the high-speed transmission mechanism 300 is connected to the rotor shaft 022 of the generator assembly 002. The generator assembly 002 and the housing 100 are arranged on a horizontal plane. The input of the low-speed transmission mechanism 200 is connected to the blade shaft 001. The blade body drives the blade shaft 001 to rotate under the action of wind, thereby transmitting torque to the low-speed transmission mechanism 200 and the high-speed transmission mechanism 300. Ultimately, the torque is output to the generator assembly 002 through the high-speed transmission mechanism 300. The generator assembly 002 operates to generate wind power.

[0050] It should be understood that by arranging the output part of the high-speed transmission mechanism 300 on the side of the output part of the low-speed transmission mechanism 200 close to the blade shaft 001, during operation, the output part of the high-speed transmission mechanism 300 is located above the output part of the low-speed transmission mechanism 200, the height of the output part of the high-speed transmission mechanism 300 is increased, and the distance from the bottom of the box body 100 is large. When the lubricating oil liquid is stored in the box body 100, the output part of the high-speed transmission mechanism 300 can be located above the liquid surface of the lubricating oil liquid, or part of the output part of the high-speed transmission mechanism 300 can be immersed in the lubricating oil liquid. It is not necessary to immerse the entire output part of the high-speed transmission mechanism 300 in the lubricating oil liquid. The sealing structure at the position where the output part of the high-speed transmission mechanism 300 is located is subjected to a small load, the probability of the sealing structure contacting debris in the oil liquid is low, the probability of the sealing structure being worn and damaged is low, and it is not easy to cause sealing failure. The position where the output part of the high-speed transmission mechanism 300 is located is not easy to cause oil leakage. In addition, the axis of the input part and the axis of the output part of the high-speed transmission mechanism 300 have an angle. By connecting the output part of the high-speed transmission mechanism 300 with the generator assembly 002, the generator assembly 002 and the speed increaser can be arranged horizontally, which is convenient for disassembly and maintenance of the two.

[0051] The following embodiments illustrate the detailed structure of the generator angle speed increaser provided in this application by way of examples.

[0052] Please combine Figure 2 and Figure 3 In this embodiment, the housing 100 may optionally be configured as a split structure. For example, the housing 100 may include a lower housing 110, a middle housing 120, and an upper housing 130, which are sequentially connected. At least a portion of the upper housing 130 is located within the area enclosed by the middle housing 120. Optionally, the lower end surfaces of the lower housing 110 and the middle housing 120 are fixedly connected by bolts, and the upper end surface of the middle housing 120 and the upper housing 130 are fixedly connected by bolts. Specifically, the upper housing 130 is provided with an outwardly turned hem. The upper housing 130 is inserted into the middle housing 120, and the hem contacts the upper end surface of the middle housing 120. The hem is fixed to the upper end surface of the middle housing 120 by bolts.

[0053] The upper shell 130 is provided with a central hole 131 and side holes 132. A low-speed oil seal assembly 400, which may be a skeleton oil seal, is mounted in the central hole 131. A sealing cover 140 is mounted outside the side hole 132. A high-speed oil seal assembly 500, which may be a skeleton oil seal, is mounted in the sealing cover 140.

[0054] Optionally, a first bearing 150 is installed in the lower shell 110, a second bearing 160 and a third bearing 170 are installed in the middle shell 120, and a fourth bearing 180 is installed in the upper shell 130. The first bearing 150, the second bearing 160 and the fourth bearing 180 are all coaxially arranged at intervals, and the axis of the third bearing 170 is perpendicular to the axis of the second bearing 160.

[0055] Please combine Figure 3 and Figure 4 In this embodiment, the low-speed transmission mechanism 200 optionally includes an input shaft 210, a planetary carrier 220, a sun gear 230, a planetary gear 240, and a ring gear 250. The input shaft 210 is connected to the planetary carrier 220, and the input shaft 210 and the planetary carrier 220 can be configured as an integral structure. The input shaft 210 is inserted into the center hole 131 and can be rotatably engaged with the upper shell 130 via the fourth bearing 180. The top of the input shaft 210 extends out of the center hole 131, and the portion of the input shaft 210 extending out of the center hole 131 is used to connect to the blade shaft 001. At the same time, the input shaft 210 passes through the low-speed oil seal assembly 400, and the input shaft 210 and the upper shell 130 are sealed by the low-speed oil seal assembly 400. The planetary carrier 220 is rotatably engaged with the lower shell 110 via the first bearing 150. Planetary gears 240 are rotatably mounted on planetary carrier 220. The number of planetary gears 240 is determined as needed and is not specifically limited in this embodiment. Sun gear 230 is sleeved onto the input shaft 210 or the planetary carrier 220 and rotatably engages with the input shaft 210 or the planetary carrier 220. Ring gear 250 is fixed within the middle housing 120 of the housing 100. All planetary gears 240 mesh with both the ring gear 250 and the sun gear 230. Sun gear 230 is connected to the input portion of the high-speed transmission mechanism 300.

[0056] Please combine Figure 3 and Figure 4 Optionally, an assembly groove is provided on the outer side of the planet carrier 220, in which a fifth bearing 260 is mounted. The sun gear 230 is inserted into the inner ring of the fifth bearing 260, and the sun gear 230 is rotatably engaged with the planet carrier 220 via the fifth bearing 260. The axial position of the fifth bearing 260 can be limited by steps on both sides of the fifth bearing 260 and a retaining ring 190. The steps can be integrated into the sun gear 230 and the planet carrier 220, and the retaining ring 190 can be mounted on both the sun gear 230 and the planet carrier 220.

[0057] Specifically, sun gear 230 is provided with a fixed shaft segment, a gear shaft segment, and an output shaft segment arranged in sequence along its axial direction. The output shaft segment is located on the side of the gear shaft segment closest to the impeller shaft. The fixed shaft segment is inserted into the inner ring. The gear shaft segment meshes with planetary gears 240. The output shaft segment is connected to the input of the high-speed transmission mechanism 300.

[0058] Please combine Figure 3 In this embodiment, the high-speed transmission mechanism 300 optionally includes a first bevel gear 310 and a second bevel gear 320. The first bevel gear 310 and the second bevel gear 320 mesh with each other and are both rotatably mounted on the housing 100. Specifically, the first bevel gear 310 is sleeved onto the outside of the planetary carrier 220 and rotatably engaged with the middle housing 120 via two second bearings 160. Furthermore, a limit nut 330 is threadedly attached to the shaft of the first bevel gear 310. The limit nut 330 abuts against the bottom second bearing 160, limiting the downward movement of the second bearings 160. The first bevel gear 310 also has a step that abuts against the top second bearing 160, thereby limiting the axial position of the two second bearings 160. It should be understood that to prevent contact between the two second bearings 160, a spacer ring 121 can be provided on the inner circumference of the middle housing 120, with the two second bearings 160 located on either side of the spacer ring 121 and abutting against it. The second bevel gear 320 is rotatably connected to the upper shell 130 through the fourth bearing 180. The axle of the second bevel gear 320 passes through the sealing cover 140 and extends out of the housing 100. The axle of the second bevel gear 320 cooperates with the sealing cover 140 through the high-speed oil seal assembly 500.

[0059] During assembly, the sun gear 230 can be connected to the first bevel gear 310 via a spline, and the axle of the second bevel gear 320 can be connected to the generator assembly 002 via a coupling 003 .

[0060] It should be understood that after the first bevel gear 310 and the second bevel gear 320 are assembled, their rotation axes are perpendicular to each other. In other embodiments, their rotation axes may be at other angles.

[0061] It should be understood that the number of the fourth bearings 180 can be two, which can be set as needed and are not listed one by one in this embodiment.

[0062] In this embodiment, an oil drain hole can be provided on the middle shell 120. The height of the oil drain hole can be set below the side hole 132. In this way, the oil filling level 004 of the lubricating oil in the housing 100 will never exceed the location of the high-speed oil seal assembly 500, and the high-speed oil seal assembly 500 will not be immersed in the lubricating oil. The high-speed oil seal assembly 500 has a long service life and is not prone to damage or leakage. It should be understood that in other embodiments, the oil drain hole can be set at a height no higher than the side hole 132. For example, the oil drain hole can be positioned in the middle of the side hole 132 to ensure that the high-speed oil seal assembly 500 is not completely immersed in the oil. In either case, the service life of the high-speed oil seal assembly 500 can be effectively extended.

[0063] The generator angle speed increaser provided in this embodiment, by providing a first bevel gear 310 and a second bevel gear 320, is connected to the generator assembly 002 via the second bevel gear 320. This allows the generator assembly 002 to be arranged horizontally relative to the housing 100, facilitating assembly and disassembly. Furthermore, the high-speed oil seal assembly 500 is not completely submerged in lubricating oil, making it less susceptible to damage, providing a long service life, excellent sealing performance, and less prone to leakage.

[0064] Please combine Figure 5 This embodiment also provides a generator angular speed increaser, which includes a generator assembly 002, an electronic control module 005, and the generator angular speed increaser of the above embodiment. Generator assembly 002 and electronic control module 005 are both integrated into housing 100, and are spaced apart in the circumferential direction of housing 100; the output portion of high-speed transmission mechanism 300 is connected to rotor shaft 022 of generator assembly 002. Integrating generator assembly 002 and electronic control module 005 into housing 100 eliminates the need for structural components such as coupling 003 that connects rotor shaft 022 of generator assembly 002 to the output shaft of high-speed transmission mechanism 300. At the same time, the circumferential space of housing 100 is rationally utilized to achieve a reasonable layout of generator assembly 002 and electronic control module 005, making the overall structure of the power generation system more compact, with a smaller overall volume, occupying less space in the engine room, and facilitating engine room layout.

[0065] It should be understood that the generator assembly 002 and the electronic control module 005 can be connected to each other via a power line. The electronic control module 005 can adjust the working state of the generator assembly 002.

[0066] Optionally, generator assembly 002 includes a housing 021 and a rotor shaft 022 rotatably engaged with housing 021. Housing 021 is fixedly connected to the side of housing 100 via bolts or other structural members. Rotor shaft 022 is coaxial with and fixedly connected to the second bevel gear. The two can be configured as an integral structure, or they can be fixedly connected via a spline or pin.

[0067] Optionally, the electronic control module 005 includes a shell and a circuit board. The circuit board is fixed in the shell, and the shell is fixed to the box body 100 by bolts and other structural parts.

[0068] In addition, please combine Figure 6 The generator angle speed increaser and the generator assembly 002 can also be assembled by connecting them through a coupling 003 to achieve torque transmission.

[0069] The power generation system provided in this embodiment not only has all the advantages of the generator angle speed increaser, but also has the advantages of compact structure, small size, small space occupation and easy assembly.

[0070] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
