Description

Technical Field

[0001] This utility model relates to the field of gear repair technology, and in particular to a gear tooth surface repair device for wind turbine gearboxes. Background Technology

[0002] The wind turbine gearbox is the core mechanical component of a wind turbine generator set, also known as a speed increaser. Its main function is to increase the low speed of the wind turbine to the high speed required for the generator to generate electricity, thereby realizing the transmission and conversion of wind energy into electrical energy. Since the gears inside the wind turbine gearbox bear torque during operation, the surface of the hardened gears will wear, and the worn hardened gears need to be repaired.

[0003] For example, CN217551337U discloses a hardened gear repair device, which includes an operating table, a rectangular mounting plate and a gear. The rectangular mounting plate is fixedly installed on the operating table. A grinding mechanism is provided on the operating table. A gear fixing mechanism is provided on the operating table. The fixing mechanism includes a motor. The motor is fixedly installed on the side wall of the rectangular mounting plate. A rotating shaft is fixedly installed on the output end of the motor. A first limiting plate is fixedly installed outside the rotating shaft. A circular mounting part is movably engaged outside the rotating shaft.

[0004] In existing technologies, clamping mechanisms can usually only clamp gears of a specific size. When faced with gears of different sizes and specifications, different clamping components need to be replaced. For gears with large differences in module and diameter, it is impossible to achieve stable clamping with the same clamping mechanism. At the same time, lasers can only repair part of the gear tooth surface, requiring frequent adjustment of the gear position, which affects the repair efficiency of the gear tooth surface. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology where different clamping components need to be replaced when dealing with gears of different sizes and specifications, and where lasers can only repair part of the gear tooth surface, affecting the repair efficiency of the gear tooth surface. Therefore, a wind turbine gearbox gear tooth surface repair device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wind turbine gearbox gear tooth surface repair device, including a processing table, a laser repair component installed on one side of the processing table, a positioning mechanism installed on the top side of the processing table, a fixed plate provided on one side of the positioning mechanism, the bottom side of the fixed plate being fixedly connected to the top side of the processing table, a clamping mechanism installed on one side of the fixed plate, the clamping mechanism including a rotating sleeve, one end of the rotating sleeve being rotatably connected to one side of the fixed plate, a movable sleeve sleeved on the outside of the rotating sleeve, a first rotating plate rotatably connected to the outer surface of the movable sleeve, a second rotating plate rotatably connected to one end of the first rotating plate, one end of the second rotating plate being rotatably connected to the outer surface of the rotating sleeve, a movable strip provided at the other end of the second rotating plate, a slot being provided on the movable strip, the other end of the second rotating plate being slidably connected inside the slot, a clamping plate being fixedly connected to the outside of the movable strip, and multiple clamping plates being evenly distributed in a ring around the center line of the movable sleeve.

[0007] Preferably, both ends of the movable bar are fixedly connected to telescopic rods, and one end of the telescopic rod is fixedly connected to the outer surface of the rotating sleeve.

[0008] Preferably, a sliding groove is provided on the outer surface of the rotating sleeve, a sliding block is slidably connected to the inner side of the sliding groove, the end of the sliding block is fixedly connected to the inner annular surface of the moving sleeve, a push rod is rotatably connected to one end of the sliding block, and a second electric push rod is fixedly connected to the other side of the fixed plate, with one end of the second electric push rod passing through the fixed plate and fixedly connected to the other end of the push rod.

[0009] Preferably, a drive motor is fixedly connected to the other side of the fixed plate, the output end of the drive motor passes through one side of the fixed plate, and a belt assembly is installed between the output end of the drive motor and the rotating sleeve.

[0010] Preferably, the positioning mechanism includes a first electric push rod, one side of which is fixedly connected to one side of the processing table, a moving block is fixedly connected to one end of the first electric push rod, a moving plate is fixedly connected to the top of the moving block, and a positioning plate is fixedly connected to one side of the moving plate.

[0011] Preferably, the bottom side of the movable plate is slidably connected to a guide rail, and one side of the guide rail is fixedly connected to the top side of the processing table.

[0012] Preferably, a positioning rod is fixedly connected to one side of the fixing plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the second electric push rod is activated, which drives the push rod to move. The moving sleeve moves axially on the rotating sleeve, causing the first and second rotating plates to rotate. Multiple second rotating plates synchronously drive their respective moving strips to move closer to the gear. Multiple clamping plates tightly abut against the outer surface of the gear from different directions, achieving a firm clamping of the gear. The drive motor works to drive the rotating sleeve to rotate. The entire clamping mechanism and the clamped gear rotate together, so that the tooth surface of the gear can be sequentially placed within the repair range of the laser repair component. This can adapt to gears of different sizes and clamp them firmly, preventing the gear from shifting or shaking during the repair process and ensuring repair accuracy.

[0015] 2. In this utility model, the first electric push rod is activated to push the moving block to move, which in turn moves the moving plate and the positioning plate together toward the gear. The positioning plate and the positioning rod abut against both sides of the gear to achieve precise positioning of the gear, ensuring that the gear is in the correct position during the subsequent repair process. This ensures that the gear is accurately positioned during the repair process and helps to improve the repair quality. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a wind turbine gearbox gear tooth surface repair device, including a processing table 1. A laser repair component 5 is installed on one side of the processing table 1. A positioning mechanism 2 is installed on the top side of the processing table 1. A fixing plate 3 is provided on one side of the positioning mechanism 2. The bottom side of the fixing plate 3 is fixedly connected to the top side of the processing table 1. A clamping mechanism 4 is installed on one side of the fixing plate 3. The clamping mechanism 4 includes a rotating sleeve 410. One end of the rotating sleeve 410 is rotatably connected to one side of the fixing plate 3. A movable sleeve 44 is sleeved on the outside of the rotating sleeve 410. A first rotating plate 45 is rotatably connected to the outer surface of the movable sleeve 44. A second rotating plate 46 is rotatably connected to one end of the first rotating plate 45. One end of the second rotating plate 46 is rotatably connected to the outer surface of the rotating sleeve 410. A movable strip 414 is provided at the other end of the second rotating plate 46. A slot 413 is opened on the movable strip 414. The other end of the second rotating plate 46 is slidably connected to the slot 413. Inside the 3, a clamping plate 48 is fixedly connected to the outer side of the moving strip 414, and multiple clamping plates 48 are evenly distributed in a ring around the center line of the moving sleeve 44; both ends of the moving strip 414 are fixedly connected to telescopic rods 43, one end of the telescopic rod 43 is fixedly connected to the outer surface of the rotating sleeve 410; a sliding groove 49 is opened on the outer surface of the rotating sleeve 410, and a sliding block 47 is slidably connected to the inner side of the sliding groove 49. The end of the sliding block 47 is fixedly connected to the inner ring surface of the moving sleeve 44, and a push rod 42 is rotatably connected to one end of the sliding block 47. A second electric push rod 41 is fixedly connected to the other side of the fixed plate 3, and one end of the second electric push rod 41 passes through the fixed plate 3 and is fixedly connected to the other end of the push rod 42; a drive motor 412 is fixedly connected to the other side of the fixed plate 3, and the output end of the drive motor 412 passes through one side of the fixed plate 3. A belt assembly 411 is installed between the output end of the drive motor 412 and the rotating sleeve 410.

[0024] First, the second electric push rod 41 is activated, and the push rod of the second electric push rod 41 extends, pushing the push rod 42 to move. The push rod 42 drives the sliding block 47 to slide in the sliding groove 49 of the rotating sleeve 410. Since the sliding block 47 is fixedly connected to the moving sleeve 44, the movement of the sliding block 47 will cause the moving sleeve 44 to move axially on the rotating sleeve 410. The movement of the moving sleeve 44 causes the first rotating plate 45 and the second rotating plate 46 to rotate. One end of the first rotating plate 45 is rotatably connected to the moving sleeve 44, and the other end is rotatably connected to the second rotating plate 46. One end of the second rotating plate 46 is rotatably connected to the rotating sleeve 410, and the other end slides in the slot 413 of the moving strip 414. As the first rotating plate 45 and the second rotating plate 46 rotate, multiple second rotating plates 46 synchronously drive their respective moving strips 414 to move closer to the gear.

[0025] The clamping plates 48 on the moving bar 414 also move accordingly. Finally, multiple clamping plates 48 tightly abut against the outer surface of the gear from different directions, achieving a firm clamping of the gear. The telescopic rod 43 extends and retracts with the movement of the moving bar 414, playing a supporting and guiding role. The belt assembly 411 consists of two pulleys and a transmission belt. The drive motor 412 is started, and the output end of the drive motor 412 drives the rotating sleeve 410 to rotate through the belt assembly 411. The rotation of the rotating sleeve 410 drives the entire clamping mechanism 4 and the clamped gear to rotate together. The push rod 42 is rotatably connected to the sliding block 47, so that the sliding block 47 and the second electric push rod 41 will not rotate with it, so that the tooth surface of the gear can be in the repair range of the laser repair component 5 in sequence. The laser repair component 5 performs repair work on the rotating gear tooth surface according to the set program. The gear is clamped from the circumferential direction by multiple clamping plates 48, which can adapt to gears of different sizes and clamp firmly, avoiding displacement or shaking of the gear during the repair process and ensuring repair accuracy.

[0026] Example 2: Figure 1 and Figure 3 As shown, the positioning mechanism 2 includes a first electric push rod 21, one side of which is fixedly connected to one side of the processing table 1. A moving block 23 is fixedly connected to one end of the first electric push rod 21. A moving plate 24 is fixedly connected to the top of the moving block 23. A positioning plate 25 is fixedly connected to one side of the moving plate 24. A guide rail 22 is slidably connected to the bottom side of the moving plate 24. One side of the guide rail 22 is fixedly connected to the top side of the processing table 1. A positioning rod 26 is fixedly connected to one side of the fixed plate 3. The positioning plate 25 and the positioning rod 26 respectively abut against both sides of the gear.

[0027] The overall effect of this embodiment is as follows: when the first electric push rod 21 is activated, the push rod of the first electric push rod 21 extends and pushes the moving block 23 to slide on the guide rail 22. The moving block 23 drives the moving plate 24 and the positioning plate 25 to move together towards the gear. Finally, the positioning plate 25 and the positioning rod 26 respectively abut against the two sides of the gear, realizing the precise positioning of the gear and ensuring that the gear is in the correct position during the subsequent repair process. It can achieve high-precision positioning of the gear, ensure that the gear is accurately positioned during the repair process, and help improve the repair quality.

[0028] The method of use and working principle of this device: Start the second electric push rod 41 to drive the push rod 42 to move. The sliding block 47 slides in the sliding groove 49, so that the moving sleeve 44 moves axially on the rotating sleeve 410. The first rotating plate 45 and the second rotating plate 46 rotate. Multiple second rotating plates 46 synchronously drive their respective moving strips 414 to move closer to the gear. The clamping plates 48 on the moving strips 414 also move accordingly. Finally, multiple clamping plates 48 tightly abut against the outer surface of the gear from different directions to achieve a firm clamping of the gear.

[0029] Start the drive motor 412. The output end of the drive motor 412 drives the rotating sleeve 410 to rotate through the belt assembly 411. The rotation of the rotating sleeve 410 drives the entire clamping mechanism 4 and the clamped gear to rotate together, so that the tooth surface of the gear can be in the repair range of the laser repair component 5 in sequence. Start the first electric push rod 21 to push the moving block 23 to move, which drives the moving plate 24 and the positioning plate 25 to move together towards the gear. The positioning plate 25 and the positioning rod 26 respectively abut against the two sides of the gear to achieve the positioning of the gear. The laser repair component 5 performs repair work on the tooth surface of the rotating gear according to the set program.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
