[0024] To make the structure and function of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] Example 1

[0026] See appendix Figures 1-7 A protective fixture for the tooth groove 1 of a wind turbine bearing is provided. The inner circumferential surface of the inner ring of the wind turbine bearing is provided with bearing internal teeth 7 and tooth groove 1. There are several protective fixtures for the tooth groove 1, and the several protective fixtures for the tooth groove 1 are adjacent to each other. The protective fixture for the tooth groove 1 includes a base 2, and a number of fixture teeth 3 are provided on the base 2. The fixture teeth 3 match the tooth groove 1, and the spatial shape formed between two adjacent fixture teeth 3 matches the bearing internal teeth 7. The tooth peaks of the bearing internal teeth 7 are in contact with the base 2.

[0027] The tool teeth 3 are at least three and are equally spaced.

[0028] The protective tooling for the tooth groove 1 is made of nitrile rubber.

[0029] A pull ring 6 is provided on the base 2 to facilitate tooling disassembly.

[0030] The tooling tooth 3 and the base 2 are connected by a rounded transition.

[0031] The length of the base 2 is equal to the center distance between two adjacent tool teeth 3 × the number of teeth. The thickness of the base 2, the thickness of the tool teeth 3, and the thickness of the bearing inner teeth 7 are equal. The thickness mentioned in this application refers to the length in the axial direction.

[0032] The height of the tooling tooth 3 is less than the height of the bearing inner tooth 7, ensuring that the tooth can be installed into the tooth groove; the center distance between two adjacent tooling teeth 3 is less than the center distance between two adjacent tooth grooves 1, ensuring that the protective tooling and the tooth surface are squeezed to form a protective effect.

[0033] The inner angle of the tooth groove 1 is 40.57°, the height of the bearing inner tooth 7 is 40.7 mm, the center distance between two adjacent tooth grooves 1 is 57 mm, and the thickness of the bearing inner tooth 7 is 5 mm; the included angle between two adjacent tool teeth 3 is 39°, the height of the tool teeth 3 is 40.1 mm, the center distance between two adjacent tool teeth 3 is 56.7 mm, the thickness of the base 2 is 5 mm, and the thickness of the tool teeth 3 is 5 mm.

[0034] This tooling is made of nitrile rubber. During the design process, the tooling is manufactured in sections according to the gear parameters. The 39° included angle on both sides of the tooth peak can ensure that the tooling has a certain amount of compression when installed on the tooth surface, which indirectly ensures that the tooth surface is properly protected and that the tooling is not easy to fall off during the sandblasting process.

[0035] Example 2

[0036] See appendix Figures 8-9 The technical solution in this embodiment is basically the same as that in embodiment 1, except that: there are at least two protective fixtures for the tooth groove 1; a first half tooth 4 and a second half tooth 5 are also provided on the base 2, the first half tooth 4 is provided at one end of the base 2, and the second half tooth 5 is provided at the other end of the base 2; the first half tooth 4 of one protective fixture for the tooth groove 1 and the second half tooth 5 of another adjacent protective fixture for the tooth groove 1 form a fixture tooth 3.

[0037] Based on the above technical solution, the first and second half teeth do not need to be the same size and shape. When adjacent first and second half teeth are installed in the tooth groove, they can be combined to form a complete tooth peak.

[0038] The two half-tooths are inserted into a tooth groove, which not only fixes the position by pressing the base, but also makes the tooling more firmly set in the tooth groove by pressing the two half-tooths.

[0039] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.
