The large-megawatt wind turbine main bearing testing machine developed by us can monitor key bearing performance such as inner and outer ring temperature, outer ring stress, vibration, and shaft friction torque in real time. The index parameters can meet the long-life assessment of wind turbine main bearings under complex working conditions, and are capable of carrying out extreme performance tests, durability tests, accelerated life tests, temperature rise tests, grease contamination tests, overspeed tests and fatigue extension failure tests.
