Description

Technical Field

[0001] This utility model relates to the field of wind turbine bearing roller testing technology, specifically a wind turbine bearing roller testing device. Background Technology

[0002] Wind turbine bearing rollers are the core components of wind turbine bearings, and their performance directly affects the bearing's load-bearing capacity, lifespan, and reliability. Cylindrical rollers, with line contact, offer high load-bearing capacity and are suitable for applications with large radial loads. Drum-shaped rollers, matched with spherical raceways, provide excellent self-aligning performance, automatically compensating for shaft deflection and concentricity errors, making them suitable for applications with combined radial and axial loads. Conical rollers can simultaneously withstand radial and axial forces, making them suitable for complex operating conditions requiring both forces. By rolling between the inner and outer rings, wind turbine bearing rollers evenly distribute the bearing load, reducing friction and improving operating efficiency and lifespan.

[0003] Currently, when conducting production testing on wind turbine bearing rollers, traditional testing equipment requires manual placement of the test piece at the designated testing position, ensuring that the position is offset, and manual unloading is also required after the test, which greatly affects the production testing efficiency of wind turbine bearing rollers.

[0004] Therefore, a wind turbine bearing roller testing device is proposed to solve the above problems. Utility Model Content

[0011] As a preferred embodiment of this utility model, positioning plates are symmetrically installed on both sides of the inside of the detection groove. A circular hole groove matching the size of the rubber pad is opened on one of the positioning plates near the detection rod.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0022] Please see Figure 1-3This embodiment provides a wind turbine bearing roller testing device, including a testing platform 1. A testing groove 15 is formed on the top of the testing platform 1. A downwardly inclined loading groove 12 and unloading groove 14 are respectively formed between the two sides of the top of the testing platform 1 and the testing groove 15. The loading groove 12 accurately transports the test piece into the testing groove 15. A unloading plate 3 is installed on the bottom inner side of the unloading groove 14 to facilitate unloading. In use, the wind turbine bearing roller testing device rolls the test piece downwards through the loading groove 15. Once the material is fed into the inspection slot 15 and the inspection piece enters the inspection slot 15, the inspection and positioning are completed. After the inspection of the wind turbine bearing roller inspection piece is completed, one end of the unloading plate 3 rotates, causing the bottom side of the inspection piece to lose its support. At this time, the wind turbine bearing roller inspection piece rolls into the inner side of the lower material trough 14 to complete the unloading. The entire process only requires manual feeding and receiving, without the need to manually position the inspection piece or manually unload it, thus effectively improving the production and inspection efficiency of wind turbine bearing rollers.

[0023] In this embodiment, as Figure 1 As shown, positioning plates 5 are symmetrically installed on both sides of the inside of the detection groove 15. A circular hole groove matching the size of the rubber pad 22 is opened on one of the positioning plates 5 near the detection rod 23. When the linear motor 2 slides to the limit distance, the detection rod 23 is located inside the detection groove 15 and the rubber pad 22 extends into the inside of the circular hole groove. Therefore, the linear motor 2 can be used to move the detection rod 23 from the inside of the detection groove 15 or move it in.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, guard plates 13 are symmetrically installed on the top two sides of the feeding trough 12. One edge of the guard plate 13 coincides with one edge of the positioning plate 5. The inner width of the feeding trough 12, the detection trough 15 and the unloading trough 14 are the same and the same as the length of the wind turbine bearing roller. Therefore, after the wind turbine bearing roller detection piece slides into the inner side of the detection trough 15 from the feeding trough 12, its position is fixed and no manual adjustment is required.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, multiple detection sensors are embedded in the bottom inner side of the detection groove 15. A rectangular groove 16 is opened at one end of the top of the detection table 1. A drive motor 6 is installed inside the rectangular groove 16. A rubber disc 51 is installed on the positioning plate 5 near the rectangular groove 16 inside the detection groove 15. The rubber disc 51 is driven by the drive motor 6. After the detection piece is placed inside the detection groove 15, the linear motor 2 drives the detection rod 23 into the detection groove 15 and through the inside of the detection piece, while squeezing the detection piece between the rubber pad 22 and the rubber disc 51. Therefore, when the drive motor 6 drives the rubber disc 51 to rotate, it can drive the detection piece to rotate, thereby realizing the detection of the outer surface and inner wall of the detection piece.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the top two ends of the feeding plate 3 are rotatably mounted on the inner bottom of the feeding trough 14, and one end of the rotating shaft of the feeding plate 3 is connected to a forward and reverse motor 4. The forward and reverse motor 4 is embedded in the outer surface of the detection table 1. In the initial state, the forward and reverse motor 4 drives the feeding plate 3 to rotate so that one end of the feeding plate 3 supports the bottom part of the detection piece. After the detection is completed, the forward and reverse motor 4 drives one end of the feeding plate 3 to rotate downward so that its top edge is flush with the inner bottom of the detection trough 15. Therefore, after the detection is completed, one end of the feeding plate 3 rotates, so that the bottom part of the detection piece loses its support and rolls into the feeding trough 14 under the action of gravity, thus completing the automatic feeding. Personnel only need to collect the material at the top of the feeding trough 14.

[0027] Working principle: When using this wind turbine bearing roller inspection device, the wind turbine bearing roller inspection piece is first placed into the loading trough 12. At this time, the inspection piece will automatically roll into the inner side of the inspection groove 15. Then, the linear motor 2 drives the inspection rod 23 into the inspection groove 15 and penetrates the inner side of the inspection piece, pressing the inspection piece between the rubber pad 22 and the rubber disc 51. When the drive motor 6 drives the rubber disc 51 to rotate, it will drive the inspection piece to rotate, thereby realizing the inspection of the outer surface and inner wall of the inspection piece. Due to the loading trough 12 and the inspection... The inner width of the groove 15 and the unloading groove 14 are the same as the length of the wind turbine bearing roller. Therefore, after the wind turbine bearing roller test piece slides into the inner side of the test groove 15 from the loading groove 12, its position is fixed and no manual adjustment is required. One end of the unloading plate 3 rotates, causing the bottom part of the test piece to lose its support force and roll into the unloading groove 14 under the action of gravity, thus completing the automatic unloading. Personnel only need to collect the material at the top of the unloading groove 14, thereby effectively improving the production and testing efficiency of wind turbine bearing rollers.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
