Turbine components: bearings - Windpower Engineering & …

16/6/2015· In main-shaft bearings, modular wind-turbine designs commonly use spherical-roller bearings (SRB) units that are more than 1m in diameter. Designers often select single SRB designs, one supported by a single main bearing and two torque arms that carry gearbox reaction loads. At least two factors contribute to early failures in main-shaft bearings.

Technical Information: Ball bearing types, selection factors, and bearing …

Ball Bearings. There are several types of ball bearings that fit specific needs. The deep-groove ball bearing, Figure 2 (a), is the most versatile. Radial loads and thrust-load capacities may be approximately equal in this bearing. When it has the proper separator, it is very good for high-speed operation.

Tribology and Lubriion Engineering Society | STLE - Back and forth with oscillating bearings

KEY CONCEPTS • Oscillating bearings wear and get damaged differently than rotational bearings. • Small angle oscillations don’t move grease around efficiently. • Countermeasures to reduce damage can be high or low tech. Cranes, wind turbine blades and airplane wing flaps all have a similar problem: the bearings that help them rotate don’t go in a full circle.
