Description

Technical Field

[0001] This utility model relates to the field of wind power reducer technology, and in particular to a tooling for press-fitting oil seals in wind power reducers. Background Technology

[0002] Currently, the installation of oil seals in existing wind turbine reducers generally adopts a manual hammering assembly process, where operators need to use hard tools such as copper rods to hammer the oil seal into the mounting hole.

[0003] However, the inventors of this application have found that the traditional method has significant defects: (1) it is difficult to ensure that the oil seal end face is evenly stressed during the hammering process, which can easily lead to deformation of the oil seal metal skeleton or damage to the rubber sealing layer; (2) it lacks an axial guide device, which can easily cause the oil seal to be installed at an angle, resulting in uneven wear of the sealing surface; (3) it is difficult to quantify and control the hammering force, which often results in improper assembly or excessive interference; (4) repeated impact between the copper rod and the oil seal contact surface can easily generate metal debris, and there is a risk of debris falling into the reducer housing and causing contamination.

[0004] Therefore, how to provide a tooling for pressing oil seals in wind turbine reducers that can not only improve pressing efficiency but also reduce oil seal damage has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling for pressing oil seals in wind turbine reducers, in order to solve the technical problem that existing oil seal pressing methods can easily affect the sealing performance and service life of reducers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A tooling for press-fitting oil seals in wind turbine reducers includes: a press-fitting sleeve having mounting holes for mounting to a press head; The press-fit block is provided with mounting holes for screwing and lifting lugs, and a vent hole is left in the middle; The washer works in conjunction with the press block to limit the position of the oil seal during the installation of the double oil seal structure. The positioning seat ring works in conjunction with the washer and the pressing block to ensure the positioning machine guides the oil seal during the pressing process.

[0007] Compared with the prior art, the tooling for press-fitting oil seals of wind turbine reducers described in this utility model has the following advantages: The tooling for pressing oil seals in wind turbine reducers provided by this utility model includes a pressing sleeve, washer, and positioning seat ring suitable for pressing oil seals of various specifications, thus offering strong versatility and low cost. The pressing block has a lightweight structure, allowing for quick replacement during production and high production efficiency. Compared with traditional processes, the tooling for pressing oil seals in wind turbine reducers provided by this utility model improves pressing efficiency by 45% and reduces the oil seal damage rate from 3% to below 0.4%.
