[0002] Wind turbine main shaft bearing forgings are blanks for the main shaft bearings, the core transmission component of wind turbine generators. They are usually made of high-quality alloy steel through heavy forging processes to obtain dense, uniform internal flow lines and fibrous structures. This structure gives them extremely high strength, toughness, and fatigue life, enabling them to withstand the huge rotational loads, impacts, and complex stresses during wind turbine operation. Their superior performance is the fundamental basis for ensuring the long-term stable operation of wind turbine main shaft bearings and extending the life of wind turbines. They are an indispensable key component in wind power equipment.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1: Refer to Figure 1-4 This is the first embodiment of the present utility model, which provides a size detection device for wind turbine main shaft bearing forgings, including a support base 1, a detection mechanism 2 and a wind turbine main shaft 3. The detection mechanism 2 is slidably connected to the outer surface of the support base 1, the wind turbine main shaft 3 is disposed on the upper surface of the support base 1, and a limit mechanism 4 is provided on the outer surface of the wind turbine main shaft 3. There are two limiting components. The two limiting mechanisms 4 include anti-slip plate 41, limiting plate 42, push plate 43 and stroke component 44. The anti-slip plate 41 is in contact with the outer surface of the wind turbine main shaft 3 on the opposite side. The limiting plate 42 is fixedly connected to the opposite side of the anti-slip plate 41 on the opposite side. The push plate 43 is fixedly connected to the opposite side of the limiting plate 42 on the opposite side. The stroke component 44 is set on the lower surface of the push plate 43. The upper surface of the support base 1 has a limiting groove 5. There are two limiting grooves 5, and the inner walls of the two limiting grooves 5 are slidably connected to the outer surface of the push plate 43.

[0022] Specifically, the spindle is clamped from both sides simultaneously by the push plate 43 and the anti-slip plate 41, which tightly fits and prevents the spindle from shaking or sliding during the inspection process. This effectively prevents measurement errors caused by workpiece movement and ensures the stability and reliability of the inspection data.

[0023] Furthermore, by placing the wind turbine main shaft 3 on the surface of the support base 1, and then pushing the push plate 43 along the inner wall of the limiting groove 5 towards the outer surface of the wind turbine main shaft 3, the push plate 43 pushes the anti-slip plate 41 towards the side of the wind turbine main shaft 3 through the limiting plate 42 until the opposite side of the anti-slip plate 41 is tightly attached to the outer surface of the wind turbine main shaft 3. Finally, the detection mechanism 2 performs dimensional detection on the surface of the wind turbine main shaft 3.

[0024] Example 2: In the second embodiment of this utility model, the stroke assembly 44 includes a stroke column 441, a stroke rod 442, and a stroke groove 443. The upper end face of the stroke column 441 is fixedly connected to the lower surface of the push plate 43. The stroke rod 442 is disposed on the outer surface of the stroke column 441. The stroke groove 443 is opened on the surface of the stroke rod 442. The inner wall of the stroke groove 443 is slidably connected to the outer surface of the stroke column 441. A transmission assembly 6 is provided on the lower side of the stroke rod 442. The transmission assembly 6 includes a support column 61, a gear 62, and a toothed plate 63. There are two support columns 61, and the outer surfaces of the two support columns 61 are fixedly connected to the inner wall of the stroke rod 442. There are two gears 62, and the inner walls of the two gears 62 are fixedly connected to the outer surfaces of the support columns 61. The outer surfaces of the toothed plate 63 and the outer surfaces of the gears 62 are in a meshing relationship. The inner wall of the support base 1 is provided with a sliding groove 7, and the inner wall of the sliding groove 7 is slidably connected to the lower surface of the toothed plate 63.

[0025] Specifically, this design enables the drive plate 43 to move closer to the wind power side.

[0026] Furthermore, the toothed plate 63 moves to the right along the inner wall of the slide groove 7. When the toothed plate 63 moves, it can mesh with the gear 62, so that the gear 62 drives the stroke rod 442 to rotate through the support column 61. The stroke rod 442 then presses the outer surface of the stroke column 441 through the inner wall of the stroke groove 443 on its surface, so that the stroke column 441 rotates along the inner wall of the stroke groove 443. The stroke column 441 can drive the push plate 43 to move closer to the outer surface of the wind turbine main shaft 3 along the inner wall of the limiting groove 5.

[0027] Example 3: In the third embodiment of this utility model, a drive assembly 8 is provided inside the toothed plate 63. The drive assembly 8 includes a threaded rod 81 and a motor 82. The outer surface of the threaded rod 81 is rotatably connected to the inside of the toothed plate 63 by a thread. The output end of the motor 82 is fixedly connected to the left end face of the threaded rod 81, and the lower surface of the motor 82 is fixedly connected to the inner wall of the support base 1. The outer surface of the threaded rod 81 is provided with a fastener 9. There are two fasteners 9. The inner walls of the two fasteners 9 are rotatably connected to the outer surface of the threaded rod 81 through bearings. The lower surface of the fastener 9 is fixedly connected to the inner wall of the support base 1.

[0028] Specifically, this design enables the drive toothed plate 63 to move to the right. The threaded connection between the toothed plate 63 and the threaded rod 81 has a certain degree of self-locking, ensuring the stability of the anti-slip plate 41 after fixing the wind turbine main shaft 3.

[0029] Furthermore, the motor 82 drives the threaded rod 81 to rotate, and the threaded rod 81 drives the toothed plate 63 to move to the right along the inner wall of the slide groove 7 through the thread.

[0030] Working principle: The wind turbine main shaft 3 is placed on the surface of the support base 1. Then, the motor 82 drives the threaded rod 81 to rotate. The threaded rod 81 drives the toothed plate 63 to move to the right along the inner wall of the slide groove 7. When the toothed plate 63 moves, it can mesh with the gear 62, so that the gear 62 drives the stroke rod 442 to rotate through the support column 61. The stroke rod 442 presses the outer surface of the stroke column 441 through the inner wall of the stroke groove 443 on its surface, so that the stroke column 441 rotates along the inner wall of the stroke groove 443. The stroke column 441 can drive the push plate 43 to move closer to the outer surface of the wind turbine main shaft 3 along the inner wall of the limiting groove 5. The push plate 43 pushes the anti-slip plate 41 closer to the wind turbine main shaft 3 through the limiting plate 42 until the opposite side of the anti-slip plate 41 is tightly attached to the outer surface of the wind turbine main shaft 3. Finally, the detection mechanism 2 performs dimensional detection on the surface of the wind turbine main shaft 3.

[0031] In summary, the combination of the limiting component, limiting groove 5, transmission component 6, sliding groove 7, drive component 8, and fixing component 9 solves the problem that the lack of limiting and fixing of the wind turbine main shaft bearing forging directly leads to inaccurate dimensional inspection results, low inspection efficiency, and may also cause equipment damage and safety hazards, resulting in multiple negative impacts on the quality control of core wind turbine components.
