Description

Technical Field

[0001] This invention relates to the field of wind power equipment transmission technology, and in particular to an integrated system for wind power transmission and lubrication monitoring with dual generator split-output. Background Technology

[0002] Existing wind turbine drive systems typically employ a single turbine input, a single gearbox for speed increase, a single high-speed output shaft, and a single generator for power generation. While this type of structure is widely used, it generally suffers from the following shortcomings: First, the back-end output link is singular, and the power output is usually concentrated on a single high-speed output shaft and a single generator. The back-end output components are concentrated, resulting in insufficient system redundancy.

[0003] Second, traditional wind power transmission chains mostly adopt a front-to-back linear series arrangement, that is, the wind turbine, main shaft, gearbox, high-speed output shaft and generator are arranged in sequence along the same main transmission direction. The overall transmission topology is relatively fixed and the structural identification is limited.

[0004] Third, the lubrication and condition monitoring structures in existing wind power transmission systems are often set separately from the transmission structure. Especially in key parts such as planetary meshing pairs, planetary gear support areas, and pin support areas, the oil supply path and condition monitoring path lack integrated consideration, making it difficult to achieve near-source oil supply and return condition sensing in key parts.

[0005] Fourth, during the long-term operation of wind power equipment, wear particles may be generated in parts such as gear pairs, pin supports, and bearings. If the state of return oil particles cannot be detected in a timely manner, it will be difficult to judge the internal wear state of the transmission system and will also be difficult to maintain later.

[0006] Therefore, a new wind power transmission system needs to be proposed, which, while maintaining the functions of wind turbine input and gear speed increase, realizes dual-branch split output and dual generator power generation at the rear end, and integrates lubrication oil supply and return oil particle monitoring with the transmission system to improve the system structure identification, operation monitoring capability and maintenance convenience. Summary of the Invention

[0007] The purpose of this invention is to provide a dual-generator split-output integrated wind power transmission and lubrication monitoring system to solve the problems of existing wind power equipment having a single output, a single generator, a simple transmission chain topology, and insufficient integration of lubrication monitoring.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A dual-generator split-output type wind power transmission and lubrication monitoring integrated system is characterized by comprising a wind turbine input section, a main shaft support section, a gear speed-increasing section, a rear split-output section, and a lubrication monitoring section; The wind turbine input section includes a hub (1) and a wind blade (2) disposed on the hub (1), and the hub (1) is connected to the front end of the low-speed main shaft (3); The main shaft support includes a main bearing (4) and a main bearing housing (5), and the low-speed main shaft (3) is supported in the main bearing housing (5) by the main bearing (4); The gear speed-increasing part is located inside the gearbox (6).

It is then transported to the support area and meshing area of ​​the planetary gear (92) through the hollow pin oil supply path (25). The returned lubricating oil flows through the return oil channel (27) and then through the return oil particle sensing device (28) before being discharged or recovered.

[0009] The first-stage planetary speed-increasing mechanism (9) is located at the front of the gearbox (6), and the sun gear shaft system (10) is located behind the first-stage planetary speed-increasing mechanism (9), and serves as an intermediate drive shaft to transmit power to the rear split output section.

[0010] The diversion tail chamber (11) is fixedly connected to the rear end of the gearbox (6). A rear diversion cavity is formed inside the diversion tail chamber (11). The central diversion pinion (12) is located in the middle of the rear diversion cavity. The left output large gear (13) and the right output large gear (14) are symmetrically arranged in the rear diversion cavity.

[0011] The rear left and right sides of the diversion tail section (11) are respectively provided with a left output hole and a right output hole.

A hollow pin oil supply path (25) is formed inside the hollow pin. The lubricating oil enters the hollow pin oil supply path (25) through the planetary carrier oil supply interface (24) and is then transported to the support area of ​​the planetary gear (92).

[0014] The return oil particle sensing device (28) is installed on the return oil path at the bottom of the gearbox (6) to detect particle information in the return lubricating oil, so as to reflect the wear status of the gear pair, pin support or bearing.

[0015] The main bearing housing (5), gearbox (6), left generator (18) and right generator (20) are installed by independent support structures respectively. The bottom middle area of ​​the gearbox (6) is reserved for oil return, monitoring and accessory arrangement.

[0016] The hub (1) is detachably connected to the front end of the low-speed main shaft (3) via a flange, and the rear end of the low-speed main shaft (3) is connected to the planetary carrier input flange (8) via a low-speed connection structure (7).

[0017] The auxiliary oil supply connection pipe (26) is connected to the oil guide channel (23) inside the housing and is used to supplement the oil supply to key lubrication parts in addition to the main oil supply.

[0018] The central splitter pinion (12) meshes with both the left output gear (13) and the right output gear (14) to distribute the power output from the sun gear shaft system (10) to the left output shaft (15) and the right output shaft (16).

[0019] The left generator (18) and the right generator (20) are respectively located on the left and right sides of the rear of the split tail section (11), so that the rear split output section forms a symmetrical dual generator output arrangement.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects: The present invention transforms the traditional single-path high-speed output into a parallel output of two branches by setting a split tail chamber (11) at the rear end of the gearbox and using a central split pinion (12) to simultaneously drive the left output large gear (13) and the right output large gear (14).

[0021] The present invention connects the left generator (18) and the right generator (20) through the left output shaft (15) and the right output shaft (16) respectively, forming a dual generator parallel power generation structure, which improves the recognizability of the back-end output structure.

[0022] This invention forms an integrated transmission chain with a single input at the front end, a first-stage planetary speed increase in the middle, and dual-branch split output at the rear end. Compared with the traditional single-output wind power transmission system, the overall topology is more obvious.

[0023] The present invention enables lubricating oil to be delivered to the support area of ​​the planetary gear (92) and the key meshing parts by setting the main oil supply port (21), the oil distribution structure (22), the planetary carrier oil supply interface (24) and the hollow pin shaft oil supply path (25), thereby achieving near-source lubrication in key areas.

Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings. It should be understood that the following embodiments are only for explaining the present invention and are not intended to limit the scope of protection of the present invention.

[0035] like Figures 1 to 7 As shown, the present invention discloses an integrated system for wind power transmission and lubrication monitoring with dual generator split-output, comprising a wind turbine input section, a main shaft support section, a gear speed-increasing section, a rear split-output section, and a lubrication monitoring section.

[0036] The wind turbine input section includes a hub (1) and a blade (2). The blade (2) is mounted on the outer periphery of the hub (1). The rear end of the hub (1) is connected to the front end of the low-speed main shaft (3) via a flange. When the wind acts on the blade (2), it drives the hub (1) to rotate. The hub (1) transmits mechanical torque to the low-speed main shaft (3).

[0037] The main shaft support section includes a low-speed main shaft (3), a main bearing (4), and a main bearing housing (5). The low-speed main shaft (3) is supported in the main bearing housing (5) by the main bearing (4). The main bearing housing (5) is located on the outer front of the gearbox (6) and is used to support the low-speed main shaft (3) and bear the input side load. The rear end of the low-speed main shaft (3) is connected to the planetary carrier input flange (8) through a low-speed connection structure (7) to input the mechanical power input from the wind turbine into the gearbox (6).

[0038] The gear speed-increasing section is located inside the gearbox (6) and includes a primary planetary speed-increasing mechanism (9) and a sun gear shaft system (10). The primary planetary speed-increasing mechanism (9) includes a planet carrier (91), planet gears (92), an internal gear ring (93), and a sun gear (94). The low-speed, high-torque power input from the wind turbine is transmitted to the primary planetary speed-increasing mechanism (9) via the low-speed main shaft (3), the low-speed connecting structure (7), and the planet carrier input flange (8). After the primary planetary speed-increasing mechanism (9) completes the initial speed-increasing stage, the power is output to the sun gear shaft system (10) by the sun gear (94). The sun gear shaft system (10) is located behind the primary planetary speed-increasing mechanism (9) and serves as an intermediate drive shaft to continue transmitting power backward.

[0039] A flow divider tail section (11) is connected to the rear end of the gearbox (6), and the flow divider tail section (11) and the rear part of the gearbox (6) together form the rear flow divider cavity. A central flow divider pinion (12) is set in the middle of the interior of the flow divider tail section (11), and the central flow divider pinion (12) is fixedly set at the rear end of the sun gear shaft system (10). A left output large gear (13) and a right output large gear (14) are respectively set on the left and right sides of the flow divider tail section (11), and the left output large gear (13) and the right output large gear (14) mesh with the central flow divider pinion (12). The left output large gear (13) is installed at the inner end of the left output shaft (15), and the right output large gear (14) is installed at the inner end of the right output shaft (16). The left output shaft (15) and the right output shaft (16) extend outward through the output holes set on the left and right sides of the rear part of the flow divider tail section (11), forming a left and right double branch output structure.

[0040] The outer end of the left output shaft (15) is connected to the left generator (18) via the left coupling (17), and the outer end of the right output shaft (16) is connected to the right generator (20) via the right coupling (19). Specifically, the left coupling (17) includes a left coupling half A (171) and a left coupling half B (172), and the right coupling (19) includes a right coupling half A (191) and a right coupling half B (192). The left coupling half A (171) is installed at the outer end of the left output shaft (15), and the left coupling half B (172) is installed at the front end of the generator shaft of the left generator (18); the right coupling half A (191) is installed at the outer end of the right output shaft (16), and the right coupling half B (192) is installed at the front end of the generator shaft of the right generator (20). Through the above structure, the central splitting pinion (12) splits the power transmitted from the sun gear shaft system (10) to the left output shaft (15) and the right output shaft (16) at the same time, and then drives the left generator (18) and the right generator (20) to generate electricity respectively, thereby realizing the parallel output of the two generators.

[0041] The lubrication monitoring section includes a main oil supply port (21), an oil distribution structure (22), an internal oil guide channel (23) in the gearbox, a planetary carrier oil supply interface (24), a hollow pin oil supply path (25), an auxiliary oil supply connection pipe (26), a return oil channel (27), and a return oil particle sensing device (28). The main oil supply port (21) is located outside the gearbox (6) and connected to an external oil source. After the lubricating oil enters through the main oil supply port (21), it is distributed to the internal oil guide channel (23) in the gearbox via the oil distribution structure (22), and enters the planetary carrier (91) through the planetary carrier oil supply interface (24). Then, it is delivered to the support area and key meshing parts of the planetary gears (92) through the hollow pin oil supply path (25) to achieve near-source lubrication. After lubricating the first-stage planetary speed-increasing mechanism (9) and related parts, the lubricating oil flows into the return oil channel (27) through the internal return path of the housing and passes through the return oil particle sensing device (28) to detect changes in particles in the return oil. The auxiliary oil supply connection pipe (26) is connected to the internal oil guide channel (23) of the housing, which can supplement the oil supply to key lubrication parts when needed.

[0042] When the invention is in operation, wind acts on the surface of the wind turbine blade (2), causing the wind turbine blade (2) to drive the hub (1) to rotate around the axis of the low-speed main shaft (3). The hub (1) transmits torque to the low-speed main shaft (3) through a flange connection. The low-speed main shaft (3) rotates stably under the support of the main bearing (4) and the main bearing seat (5). The main shaft support section is used to bear the input load on the wind turbine side and to provide stable support for the input at the front end of the gearbox (6), so that the low-speed main shaft (3) can transmit low-speed high-torque power to the gearbox (6) through the low-speed connection structure (7) and the planetary carrier input flange (8).

[0043] After the power enters the gearbox (6), it first acts on the first-stage planetary speed-increasing mechanism (9). The planet carrier (91) receives the input torque and drives the planetary gears (92) to move. The planetary gears (92) mesh with the internal gear ring (93) and the sun gear (94), so that the low-speed, high-torque input is converted into a higher-speed output through the first-stage planetary transmission. The sun gear (94) is connected to the sun gear shaft system (10). The power output by the first-stage planetary speed-increasing mechanism (9) is transmitted from the sun gear (94) to the sun gear shaft system (10). The sun gear shaft system (10) continues to transmit power to the rear end of the gearbox (6) as an intermediate drive shaft.

[0044] The rear end of the sun gear shaft (10) extends into the splitter tail section (11) and drives the central splitter pinion (12) to rotate. The central splitter pinion (12) meshes with both the left output gear (13) and the right output gear (14). When the central splitter pinion (12) rotates, the meshing action of its teeth transmits the single-path power from the sun gear shaft (10) to the left output gear (13) and the right output gear (14) respectively, thereby forming two parallel output branches on the left and right sides within the splitter tail section (11).

[0045] The left output gear (13) is fixedly installed inside the left output shaft (15), and the right output gear (14) is fixedly installed inside the right output shaft (16). Therefore, after the left output gear (13) and the right output gear (14) are driven by the central splitter pinion (12), they respectively drive the left output shaft (15) and the right output shaft (16) to rotate. The left output shaft (15) and the right output shaft (16) extend outward through the output holes on the left and right sides of the rear of the splitter tail section (11), forming a left and right dual-branch mechanical output.

[0046] The outer end of the left output shaft (15) is connected to the generator shaft of the left generator (18) via the left coupling (17), and the outer end of the right output shaft (16) is connected to the generator shaft of the right generator (20) via the right coupling (19). The left coupling (17) and the right coupling (19) are used to realize the power transmission and assembly docking between the output shaft and the generator shaft, respectively. As a result, the output of the rear end of the gearbox (6) no longer uses a single high-speed shaft to drive a single generator, but instead distributes the power to the left generator (18) and the right generator (20) through the gear splitting structure in the splitting tail compartment (11), forming a dual-generator parallel power generation mode.

[0047] While the transmission system is running, the lubrication monitoring section works synchronously. Lubricating oil enters the gearbox (6) from an external oil source through the main oil supply port (21) and is distributed to the internal oil guide channel (23) of the gearbox by the oil distribution structure (22). The internal oil guide channel (23) guides the lubricating oil to the planetary carrier oil supply interface (24), and the lubricating oil then enters the planetary carrier (91) and is delivered to the support area and key meshing area of ​​the planetary gear (92) through the hollow pin shaft oil supply path (25), providing near-source lubrication for the planetary gear (92), hollow pin shaft and related meshing pairs.

[0048] After lubrication, the lubricating oil flows along the return path inside the gearbox (6) and collects in the return oil channel (27). When the returning lubricating oil passes through the return oil particle sensor (28), the return oil particle sensor (28) detects abrasive or metal particles in the oil to reflect the wear condition of parts such as gear pairs, pin supports, and bearings. When it is necessary to increase the oil supply to critical parts, the auxiliary oil supply connection pipe (26) can cooperate with the oil guide channel (23) inside the gearbox to supplement the oil supply to critical lubrication parts.

[0049] Therefore, this invention forms a mechanical transmission path of "wind turbine input - first-stage planetary speed increase - sun gear shaft transmission - rear gear splitting - dual generator output" during power transmission; and an oil circulation path of "main oil supply - oil splitting - near-source oil supply - oil return - particle monitoring" during lubrication monitoring. The two paths are arranged in coordination around the gearbox (6) and the splitting output structure, so that the wind power equipment can simultaneously have the functions of dual-branch splitting output, dual generator power generation, near-source lubrication of key parts and oil return wear monitoring.
