Description

Technical Field

[0001] This utility model belongs to the field of mechanical testing technology, specifically relating to a brake debugging platform for a yaw motor. Background Technology

[0002] The yaw motor brake commissioning platform is a specialized device designed specifically for the maintenance and commissioning needs of yaw drives in wind turbines. As a key component of wind turbines, the yaw drive is responsible for adjusting the rotor direction to ensure it always faces the wind, thus achieving efficient wind energy capture. Because wind turbines are typically installed outdoors in complex and harsh environments, yaw drives are prone to failure, requiring specialized equipment for repair and commissioning to ensure their normal operation.

[0003] However, when used in unspecified locations, the lubrication between the testing gear and the drive gear gradually decreases, usually requiring manual pre-lubrication, which makes it impossible to continuously lubricate during the testing process. Utility Model Content

[0004] The purpose of this utility model is to provide a brake debugging platform for yaw motors, so as to solve the problem mentioned in the background art that when used in an unspecified location, manual lubrication is usually required in advance, which makes it impossible to continuously perform lubrication during the testing process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a brake debugging platform for a yaw motor, comprising a working chamber and two test seats installed on the inner wall of the lower end of the working chamber;

[0006] Both test stands have drive motors installed inside the upper outer walls;

[0007] Both drive motors have detection gears connected to their upper outer walls.

[0008] The upper side of the working chamber is provided with a drive body, and a connector is fixedly connected to the lower outer wall of the drive body. A drive gear that meshes with the detection gear is fixedly connected to the lower outer wall of the connector.

[0009] Oil boxes are fixedly connected to the inner walls of both the left and right ends of the working chamber to store lubricating oil. Oil-absorbing sponges are installed inside the two oil boxes, and guide tubes are fixedly connected to the lower outer walls of the two oil boxes to guide the lubricating oil to the gear meshing area.

[0010] Preferably, both oil boxes have oil outlets on their lower outer walls to guide lubricating oil into the guide tube.

[0011] Preferably, the upper outer walls of both oil boxes are provided with top covers, and the lower outer walls of both top covers are fixedly connected with threaded heads that engage with the oil boxes to limit the position of the top covers.

[0012] Preferably, the upper outer walls of both oil boxes are provided with threaded grooves for threaded heads to engage, and both guide tubes are inclined.

[0013] Preferably, the upper outer wall of the working chamber is provided with a cover plate, and the upper outer wall of the cover plate is provided with a plurality of fastening screws that engage with the working chamber to restrict the position of the cover plate.

[0014] Preferably, a plurality of fixing screws are provided between the driver body and the cover plate to restrict the position of the driver body by fixing screws, and observation windows are embedded in the upper outer wall of the cover plate near the left and right sides respectively.

[0015] Preferably, a base plate is fixedly connected to the lower outer wall of the working chamber.

[0016] Preferably, both drive motors, the test mount, and the driver body are electrically connected to an external power source.

[0017] Compared with the prior art, this utility model provides a brake debugging platform for a yaw motor, which has the following advantages:

[0018] By installing an oil box, oil-absorbing sponge, and guide tube, the oil box acts as a storage container for lubricating oil during the testing of the gear meshing between the testing gear and the drive gear. This ensures a continuous supply of lubricating oil, which is then delivered to the gear meshing point via the guide tube. Regardless of the testing location, continuous lubrication is achieved without frequent manual intervention, ensuring the gears remain well-lubricated throughout the testing process. This guarantees the continuity and stability of the testing and eliminates reliance on specific external lubrication facilities or conditions. Compared to traditional manual pre-lubrication, operators only need to periodically check the lubricating oil level in the oil box, eliminating the need for repeated lubrication during the testing process. This significantly reduces the frequency of manual operations, allowing operators to focus more on observing and analyzing the test data, thus improving work concentration and efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-4 The diagram shows a brake debugging platform for a yaw motor, which includes a working chamber 2 and two test seats 11 installed on the lower inner wall of the working chamber 2.

[0026] Both test seats 11 have drive motors 10 installed inside the upper outer walls;

[0027] Both drive motors 10 have detection gears 9 connected to the upper outer walls of their respective drive motors 10.

[0028] A driver body 7 is mounted on the upper side of the working chamber 2. A connector 12 is fixedly connected to the lower outer wall of the driver body 7. A driver gear 8, which meshes with the detection gear 9, is fixedly connected to the lower outer wall of the connector 12. The driver body 7 is hoisted above the working chamber 2, aligning the driver gear 8 at the lower end of the connector 12 with the detection gear 9 on the test seat 11. The driver body 7 is then slowly lowered, ensuring that the driver gear 8 and the detection gear 9 are accurately meshed. Simultaneously, the driver body 7 is ensured to be securely installed and will not shake or shift during operation. The power cord of the drive motor 10 is then connected to an external stable power source, ensuring a secure connection. There were no loose or leaking phenomena. After connecting the power supply, a preliminary power-on test was conducted to observe whether the rotation direction of the drive motor 10 was correct. The drive motor 10 was started through the operator of the external device, and the speed of the drive motor 10 was gradually increased to make the detection gear 9 and the driver gear 8 start to run, driving the driver body 7 to simulate the actual working conditions. The driver body 7 was allowed to run continuously under the set working conditions for a period of time to observe its operational stability. The operating parameters of the driver body 7 were monitored in real time through the test base 11 and compared with the standard parameters of the wind turbine yaw drive to determine whether the performance of the driver body 7 met the requirements.

[0029] Oil boxes 13 are fixedly connected to the inner walls of both ends of the working chamber 2 to store lubricating oil. Oil-absorbing sponges 14 are installed inside the two oil boxes 13. Guide tubes 17 are fixedly connected to the lower outer walls of the two oil boxes 13 to guide the lubricating oil to the gear meshing area. When lubricating oil is injected into the oil box 13, the oil-absorbing sponges 14 will gradually absorb and store the lubricating oil. The lubricating oil flows slowly down the guide tubes 17 and acts directly on the gear teeth. During the rotation of the gear, the lubricating oil is evenly distributed in the meshing area to form an oil film, reducing friction and wear between gears and ensuring that the gear can operate smoothly and stably, simulating the good lubrication environment of the wind turbine yaw drive in actual operation.

[0030] like Figure 3 and Figure 4 As shown, the lower outer walls of both oil boxes 13 are provided with oil outlets 16 to guide lubricating oil into the guide pipe 17. The upper outer walls of both oil boxes 13 are provided with top covers 18. The lower outer walls of both top covers 18 are fixedly connected with threaded heads 15 that engage with the oil boxes 13 to limit the position of the top covers 18.

[0031] After the lubricating oil flows out of the oil outlet 16, it enters the inclined guide tube 17. The inclined design of the guide tube 17 utilizes the principle of gravity to allow the lubricating oil to flow naturally along the pipe and be accurately guided to the meshing area of ​​the detection gear 9 and the drive gear 8. When adding lubricating oil to the oil box 13, first rotate the top cover 18 counterclockwise to unscrew it, and then add lubricating oil to the oil box 13. After adding, screw the top cover 18 back in the opposite direction.

[0032] like Figure 4 As shown, the upper outer walls of both oil boxes 13 are provided with threaded grooves for threaded heads 15 to engage, and both guide tubes 17 are inclined.

[0033] The threaded groove provides the threaded position of the threaded head 15, making it easy to open the top cover 18 and add lubricating oil into the oil box 13.

[0034] like Figure 1 As shown, a cover plate 3 is provided on the upper outer wall of the working chamber 2. Multiple fastening screws 5 are provided on the upper outer wall of the cover plate 3 and are screwed into the working chamber 2 to restrict the position of the cover plate 3. Multiple fixing screws 6 are provided between the driver body 7 and the cover plate 3 to restrict the position of the driver body 7 by fixing screws 6. Observation windows 4 are embedded in the upper outer wall of the cover plate 3 near the left and right sides respectively.

[0035] The cover plate 3 installed on the upper outer wall of the working chamber 2 is fixed to the working chamber 2 by multiple fastening screws 5. The drive body 7 is connected to the cover plate 3 by multiple fixing screws 6, thereby restricting the position of the drive body 7. The setting of fixing screws 6 ensures that the drive body 7 remains stable during the operation of the equipment and will not be displaced due to external forces such as vibration and impact. This ensures the meshing accuracy between the drive body 7 and the detection gear 9, thereby ensuring the accuracy of the detection and debugging work. During the operation of the equipment, the operator can observe the operating status of the drive body 7, the meshing of the gears, and the working status of the lubrication system in real time through the observation window 4.

[0036] like Figure 1 As shown, a base plate 1 is fixedly connected to the lower outer wall of the working chamber 2, and the two drive motors 10, the test seat 11 and the driver body 7 are all electrically connected to an external power source.

[0037] After the drive motor 10 is powered on, it transmits power to the detection gear 9 which is connected to it. The detection gear 9 meshes with the drive gear 8 which is fixedly connected to the lower connector 12 of the drive body 7, thereby driving the drive body 7 to rotate.

[0038] The implementation principle of this embodiment is as follows: The driver body 7 is hoisted above the working chamber 2, aligning the driver gear 8 at the lower end of the connector 12 with the detection gear 9 on the test seat 11. The driver body 7 is slowly lowered, ensuring accurate meshing between the driver gear 8 and the detection gear 9, while ensuring the driver body 7 is securely installed and will not shake or shift during operation. The power cord of the drive motor 10 is connected to an external stable power supply, ensuring a secure connection without loosening or leakage. After powering on, a preliminary power-on test is performed to observe whether the rotation direction of the drive motor 10 is correct. Using the operator of an external device, the drive motor 10 is started, and its speed is gradually increased, causing the detection gear 9 and the driver gear 8 to start rotating, driving the drive... The main body 7 simulates actual operating conditions, allowing it to run continuously for a period of time under set conditions to observe its operational stability. The operating parameters of the main body 7 are monitored in real time through the test base 11 and compared with the standard parameters of the wind turbine yaw drive to determine whether the performance of the main body 7 meets the requirements. When lubricating oil is injected into the oil box 13, the oil-absorbing sponge 14 gradually absorbs and stores the lubricating oil. The lubricating oil flows slowly down the guide tube 17 and acts directly on the gear tooth surface. During gear rotation, the lubricating oil is evenly distributed on the meshing part, forming an oil film, reducing friction and wear between gears, and ensuring that the gears can operate smoothly and stably, simulating a good lubrication environment for the wind turbine yaw drive in actual operation.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
