Manufacturing method of device for preventing high temperature and back channeling of main shaft bearing of wind power generator

1. The utility model relates to the technical field of auxiliary equipment for wind power generation, in particular to a device for preventing high temperature and back channeling of the main shaft bearing of a wind power generator.

Background technique:

2. The principle of wind power generation is to use the wind to drive the windmill blades to rotate, and then increase the rotating speed through a speed increaser to promote the generator to generate electricity. According to the windmill technology, the breeze speed is about three meters per second (the degree of breeze) ), you can start power generation. Wind power generation is forming a boom in the world, because wind power generation does not require fuel, nor does it produce radiation or air pollution. At present, most of the main shaft bearings of wind turbines are spherical roller bearings. There is a certain thrust effect, but as the running time increases, the cage wear becomes more and more serious, which will cause the thrust effect of the thrust bearing to weaken, the axial load on the bearing exceeds the normal value, and the operating temperature of the bearing will exceed The warning value seriously affects the running time of the wind turbine, and the high temperature problem caused by the rear bearing of the bearing. The general solution is to replace the main shaft bearing. This technology has a long construction period and high cost. In view of this, in-depth study of the above problems led to this case produce.
