Description

Technical Field

[0001] This utility model belongs to the technical field of planetary carrier shaft hole correction in wind turbine gearboxes, and more specifically, it relates to a device for correcting the coaxiality of planetary carrier shaft holes in wind turbine gearboxes. Background Technology

[0002] Among the core components of wind turbine gearboxes, the coaxiality of the planetary carrier's shaft holes is a key indicator affecting the gearbox's transmission efficiency, operational stability, and service life. The planetary carrier typically has multiple mounting holes distributed on its circumferential surface. These holes need to be precisely matched with the planetary gear shafts. If the coaxiality deviation exceeds the allowable range, it will lead to uneven gear meshing clearance and localized stress concentration, which in turn will cause vibration, increased noise, and even serious faults such as gear wear and breakage, increasing the maintenance costs and downtime risks of wind turbine equipment.

[0003] The current methods for coaxiality correction of planetary carrier shaft holes in wind turbine gearboxes have the following problems:

[0004] Traditional calibration relies on manual measurement and adjustment, which is inefficient and its accuracy is greatly affected by the operator's experience, making it difficult to meet the production requirements of high-precision wind turbine gearboxes.

[0005] The lack of intuitive scale display and quantitative adjustment mechanism makes it impossible to monitor deviation data in real time during the calibration process, resulting in unstable calibration results and a high rework rate. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a coaxiality correction device for the planetary carrier shaft hole of a wind turbine gearbox. This device solves the problems of existing correction methods that rely on manual measurement and adjustment, resulting in low efficiency and accuracy that is greatly affected by the operator's experience. These methods are insufficient to meet the production requirements of high-precision wind turbine gearboxes and lack intuitive scale display and quantitative adjustment mechanisms. Furthermore, the device cannot monitor deviation data in real time during the correction process, leading to unstable correction results and a high rework rate.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A coaxiality correction device for the planetary carrier shaft hole of a wind turbine gearbox includes a device base; a chuck clamp is fixedly installed at the top center of the device base, and the planetary carrier body is clamped at the top center of the chuck clamp. Three mounting holes are opened on the circumference of the planetary carrier body. The top rear position of the device base is fixedly connected to the bottom rear end position of the support frame. A lifting rod is fixedly installed at the inner center position of the support frame. The lifting rod is located directly above the device base. The bottom center position of the lifting rod is fixedly connected to the top center position of the motor. A scale is fixedly installed at the bottom position of the motor. The motor shaft passes through the center position of the scale and is fixedly connected to the top center position of the pointer adjustment seat. The pointer adjustment seat is located directly below the scale.

[0009] According to one embodiment of the present invention, a positioning frame is fixedly installed at the bottom of the pointer adjustment seat, the bottom of the positioning frame is provided with a scale, and a screw A is rotatably connected to the inside of the positioning frame.

[0010] According to one embodiment of the present invention, a slider is slidably connected to the inside of the positioning frame, a threaded hole is provided at the upper middle position of the front end of the slider, the screw A is located in the threaded hole of the slider, and the bottom middle position of the slider is rotatably connected to the top middle position of the rotating rod.

[0011] According to one embodiment of the present invention, an auxiliary frame is fixedly installed on the circumferential surface of the rotating rod, a scale is provided at the bottom of the auxiliary frame, and a screw B is rotatably connected to the inner part of the auxiliary frame.

[0012] According to one embodiment of the present invention, a positioning slide rod is slidably connected to the inner position of the auxiliary frame, and a threaded hole is opened at the upper middle position of the side of the positioning slide rod, and the screw B is located in the threaded hole of the positioning slide rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The planetary carrier is securely held by a chuck fixture to prevent workpiece displacement from affecting accuracy during calibration. The pointer adjustment seat and related components are rotated by a motor, and the rotation angle can be precisely controlled by the dial, replacing manual rotation and positioning, which greatly improves operating efficiency and angle positioning accuracy.

[0015] Both the positioning frame and the auxiliary frame are equipped with scales. By adjusting the lateral position of the slider with screw A and adjusting the spacing of the positioning sliders with screw B, the movement distance of each component can be read intuitively, realizing the quantitative adjustment of the shaft hole position deviation. Operators can monitor the data changes in real time during the calibration process through the scales, make timely adjustments, reduce deviations caused by blind operation, and reduce the rework rate.

[0016] By cooperating with the rotating rod and the positioning slide rod, different mounting holes on the planetary carrier can be respectively matched. Combined with the rotation function driven by the motor, multiple mounting holes can be detected and corrected in sequence. By comparing the detection data of different mounting holes, the coaxiality and positional accuracy of multiple shaft holes are ensured to meet the high precision requirements of wind turbine gearboxes for planetary carrier shaft holes. This ensures the transmission efficiency, operational stability and service life of the gearbox, and reduces the maintenance cost and downtime risk of wind power equipment.

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 5 As shown:

[0029] This utility model provides a device for correcting the coaxiality of the planetary carrier shaft hole of a wind turbine gearbox, including a device base 1; a chuck clamp 101 is fixedly installed at the top center of the device base 1, and the planetary carrier body 3 is clamped at the top center of the chuck clamp 101. Three mounting holes are opened on the circumference of the planetary carrier body 3. The top rear position of the device base 1 is fixedly connected to the bottom rear end position of the support frame 102. A lifting rod 103 is fixedly installed at the inner center position of the support frame 102. The lifting rod 103 is located directly above the device base 1. The bottom center position of the lifting rod 103 is fixedly connected to the top center position of the motor 104. A scale 105 is fixedly installed at the bottom position of the motor 104. The rotating shaft of the motor 104 passes through the center position of the scale 105 and is fixedly connected to the top center position of the pointer adjustment seat 106. The pointer adjustment seat 106 is located directly below the scale 105.

[0030] The bottom of the pointer adjustment seat 106 is fixedly equipped with a positioning frame 2, the bottom of the positioning frame 2 is provided with a scale, and the internal position of the positioning frame 2 is rotatably connected with a screw A201.

[0031] The positioning frame 2 has a slider 202 slidably connected inside. The upper front end of the slider 202 has a threaded hole. The screw A201 is located in the threaded hole of the slider 202. The bottom middle position of the slider 202 is rotatably connected to the top middle position of the rotating rod 203.

[0032] An auxiliary frame 204 is fixedly installed on the circumference of the rotating rod 203. The bottom of the auxiliary frame 204 is marked with a scale, and a screw B205 is rotatably connected to the inside of the auxiliary frame 204.

[0033] The auxiliary frame 204 has a slidably connected positioning slide rod 206 inside. The positioning slide rod 206 has a threaded hole at the upper middle position on its side, and the screw B205 is located in the threaded hole of the positioning slide rod 206.

[0034] When using:

[0035] The planetary carrier 3 to be calibrated is placed on the chuck clamp 101 and clamped and fixed by the chuck clamp 101 to ensure that the planetary carrier 3 does not shift during the calibration process.

[0036] By extending the lifting rod 103, the height of the motor 104 and the positioning frame 2 is lowered. Next, the screw A201 is rotated to adjust the lateral position of the slider 202 in the positioning frame 2, so that the rotating rod 203 is directly above the axis of a mounting hole of the planetary carrier 3. The scale position of the adjusting slider 202 in the positioning frame 2 is checked to determine the distance between the mounting hole of the planetary carrier 3 below the rotating rod 203 and the center of the planetary carrier 3.

[0037] By rotating the slider 202 and the rotating rod 203, the position of the auxiliary frame 204 is adjusted. Then, the screw B205 is rotated to adjust the distance between the positioning slide rod 206 and the rotating rod 203 until the positioning slide rod 206 is located above another mounting hole of the planetary carrier 3. The movement distance of the positioning slide rod 206 is read through the scale of the auxiliary frame 204 to determine the straight distance between the two mounting holes detected by the planetary carrier 3.

[0038] After taking the distance between two adjacent mounting holes of the planetary carrier 3, start the motor 104 to drive the pointer adjustment seat 106 and the positioning frame 2 to rotate 120°, so that the position of the rotating rod 203 reaches the position of the positioning slide rod 206. The positioning slide rod 206 is then adjusted to be above the last mounting hole to be inspected on the planetary carrier 3 to detect the straight distance between the two mounting holes, ensuring that the spacing between the three mounting holes of the planetary carrier 3 is the same.
