Does the questioner want to ask about "the causes of damage and cracks in the double-split tapered roller bearings of wind turbine main shafts"? Fatigue failure and poor lubrication.
1. Fatigue failure: During long-term operation, double-split tapered roller bearings of wind turbine main shafts bear huge alternating loads and are prone to fatigue failure, resulting in cracks on the bearing surface. .
2. Poor lubrication: Poor lubrication will increase the friction on the bearing surface, accelerate the wear of the bearing, and cause cracks on the bearing surface.
1) Can it protect bearing gears?
2) Reduce wear and friction, have high load-bearing capacity and prevent gluing
3) Absorb impact and vibration
4) Prevent fatigue, pitting corrosion, micropitting
5) Cooling, rust prevention, and corrosion resistance
