As wind turbines
develop towards ultra-high power, replacing rolling bearings with sliding bearings can effectively reduce the overall size of wind turbine units, lower the cost of wind power rotating equipment, and improve unit operating efficiency, providing a new technical route for wind turbine bearing design. PEEK composite materials have a low coefficient of friction and are wear-resistant. Wear-resistant bearings made from PEEK composite materials exhibit excellent self-lubricating properties and are widely used in wind turbine sliding bearing systems. They effectively improve the friction and wear performance of sliding bearings, reduce starting friction resistance, and can operate normally for short periods or even long periods without lubrication. Furthermore, PEEK composite materials possess excellent fatigue resistance, high and low temperature resistance, corrosion resistance, high load-bearing capacity, lightweight properties, and dimensional stability, maintaining stable wear resistance under low-speed, heavy-load, and high-temperature conditions.
Modular bearing assemblies are
designed to rationally arrange bearings according to the actual operating conditions of the unit, achieving modular bearing assemblies that are low-cost, highly reliable, easy to replace, and have no machining limitations.
