Embodiment Construction
[0015] In order to better understand the technical solution of the present invention, the following will be described in detail through specific embodiments in conjunction with the accompanying drawings:
[0016] see figure 1 and figure 2 , a sealing structure for wind power bearings in the manufacturing process of the present invention, including an inner sealing ring 1 and an outer sealing ring 2, wherein:
[0017] The inner sealing ring 1 includes a main sealing body 10 with a circular cross section and two sealing lips 11 and 12 correspondingly extending from both sides of the outer end of the main sealing body 10; the main sealing body 10 is sandwiched between wind power bearings In the gap between the inner and outer bearing rings 3 and 4, the diameter of the main seal body 10 and the gap distance between the inner and outer bearing rings 3 and 4 of the wind power bearing are interference fit; a sealing lip 11 is in conflict with the inside On the axial end surface of...

The invention discloses a seal structure for wind power bearing manufacture. The seal structure comprises an inner seal ring and an outer seal ring. The inner seal ring comprises a main sealing body of which the cross section is circular and two sealing lips extending respectively from two outer end sides of the main sealing body. The main sealing body is sandwiched in a gap between an inner bearing ring and an outer bearing ring of the wind power bearing. One of the two sealing lips presses against an axial end face of the inner / outer bearing ring, and the other one of the two sealing lips presses against a radial end face of the inner / outer bearing ring and produces a certain deformation. The outer seal ring is arranged at an outer part of the inner seal ring in the way that the outer seal ring is embedded into a dustproof groove of the inner / outer bearing ring, and an inclosed cavity is formed between the inner seal ring and the outer seal ring. The seal structure can bear a certain pressure produced by sandblast, zinc spray and paint spray, effectively guarantee raceway cleanliness before and after wind power bearing spray-coating, and guarantee seal reliability in bearing assembling.
Description
technical field [0001] The invention relates to a sealing structure used in the manufacturing process of wind power bearings. Background technique [0002] The yaw and pitch bearings installed on the wind turbine system are required to guarantee a service life of 20 years, and sand and dust are not allowed on the raceways of the bearings. If there is sand and dust on the bearing raceway, the bearing may be stuck or the raceway may be damaged. Therefore, the cleanliness of the raceway is very important for bearings to ensure a 20-year service life and good performance. During the assembly stage of the wind power yaw pitch bearing, the surface of the bearing needs to be treated with anticorrosion, that is, surface pretreatment, surface sandblasting treatment, surface zinc spraying treatment and surface painting treatment are required in sequence. During the anti-corrosion treatment, the sealing ring installed between the inner and outer bearing rings needs to withstand a cer...
