PERFORMANCE TESTING DEVICE OF BEARING FOR WIND POWER GENERATOR

摘要

PURPOSE: A device for bearing functional test for an aero-generator is provided to confirm whether or not required conditions for targeted load are satisfied by observing a plastic deformation and desquamation of a rolling surface of a pitch bearing and concavity bearing. CONSTITUTION: A device for bearing functional test for an aero-generator comprises a base frame(100), an actuating frame(200), a horizontal actuator(HF), and a vertical actuator(VF). The base frame supports a bearing assembly which is an object of a functional test in the bottom surface. The actuating frame is arranged in the upper part of the bearing assembly to add load to the bearing assembly. The horizontal actuator pressurizes a part of the actuating frame in a horizontal direction. The horizontal actuator adds force to the horizontal direction to the bearing assembly. The vertical actuator pressurizes the rest part of the vertical actuating frame in a vertical direction. The vertical actuator adds vertical direction load or moment load to the bearing assembly.
