Classification and characteristics of wind power bearing

wallpapers News 2021-09-09
Bearing is the core component of wind turbines. Wind power bearings range from blades, spindles and yaw bearings to high-speed bearings for gearboxes and generators.
Main features of wind power bearing
1. Poor use environment;
2. High maintenance cost;
3. Need for high life expectancy;
Wind power bearing classification
Wind turbine bearings mainly include yaw bearings, pitch bearings, spindle bearings, gearbox bearings, generator bearings and so on.
Namely: pitch bearing, yaw bearing, transmission system bearing (spindle and gearbox bearing).
Generator bearings
Bearing types: deep groove ball bearings, angular contact bearings, etc.
Working conditions: high speed (1000-1500RPM), high temperature (90-120℃), heavy load.
Grease requirements: excellent shear stability, good oxidation stability, good magic resistance, excellent low-temperature start performance, etc.
Main bearing
Bearing types: tapered roller bearing, spherical bearing, three-row cylindrical roller bearing, etc.
Working conditions: low speed (25 RPM), wide temperature, large load, large change, large vibration, high humidity.
Grease requirements: excellent wear resistance, good oxidation stability, excellent low-temperature start performance, good water resistance, etc.
Pitch/Yaw bearings
Bearing Type: four-point contact ball bearing, etc.
The working condition features: stop more than turn, wide temperature, load, vibration, high humidity.
Grease requirements: excellent corrosion resistance, fretting resistance, excellent low temperature starts performance, good water resistance, good oxidation stability, etc.
