Abstract

The invention discloses a new wind power main bearing sealing structure, which relates to the technical field of wind power bearing protection, aiming at the inconvenient fast installation and disassembly of the retaining ring used for sealing on the existing wind power main bearing, and the inconvenient mass production and the inability to reduce the production cost Problem, the following scheme is proposed, including bearing outer ring, bearing inner ring and multiple balls, the bearing inner ring is movably sleeved inside the bearing outer ring, and a plurality of bearing outer rings and bearing inner rings are provided ball, the front outer wall and the back outer wall of the outer ring of the bearing are welded with a first mounting block, and the side of the first mounting block away from the outer ring of the bearing is rotatably connected with a movable plate, and the movable plate and the first mounting block There is a first limit mechanism between them. The invention not only facilitates fast installation and disassembly of the sealing plate, but also has a simple and easy-to-obtain structure, can be produced in large quantities with low production costs, and provides anti-collision protection for the bearings conveniently, avoiding damage caused by external force.

Description

technical field

[0001] The invention relates to the technical field of wind power bearing protection, in particular to a novel wind power main bearing sealing structure. Background technique

[0002] Wind power refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source. It has been used by people for a long time, mainly through windmills to pump water and grind flour. People are interested in how to use wind to generate electricity. Wind power bearings are special bearings that are used in harsh environments, require high maintenance costs, and require high service life.

[0003] The existing wind power main bearings generally have retaining rings between the inner and outer rings for sealing and dustproof protection of the balls. The retaining ring needs to be processed together with the bearing, so that the size needs to be met accordingly, which increases the processing procedures and difficu...
