Applications

Wind power generation main bearing belongs to the field of wind power generators. The characteristics are: main bearing upper outer ring, main bearing lower outer ring, thrust cylindrical rollers, cage, main bearing inner ring. There are two rows of thrust cylindrical rollers on the inside of the main bearing lower outer ring. There is a single row of radial cylindrical rollers on the outside, and the cylindrical rollers are placed on the cage. The utility model eliminates the main shaft, can greatly reduce the impact of the original rigid shaft on the gear box and the generator, prolongs the service life of the gear box and the generator, realizes good force transmission, and is easy to repair and disassemble. And it can withstand large axial load and large radial load, and can well adapt to the working conditions of spindle-less wind turbines and meet their stress requirements.
