DEVICE FOR EVALUATING THE PERFORMANCE AND DURABILITY OF A LARGE BEARING, CAPABLE OF EMULATING THE ROTARY BLADE OF A WIND GENERATOR AND A BEARING FOR THE ROTARY BLADE

摘要

PURPOSE: A device for evaluating the performance and durability of a large bearing is provided to evaluate the performance and the durability of the large bearing by testing the large bearing for the rotary blade of a wind generator in the condition of an actual wind generator.;CONSTITUTION: A device for evaluating a large bearing comprising a pitch bearing(110), a rotating unit(170) and a front disc(120). A ring gear(112) is installed in the pitch bearing. The pitch bearing emulates the bearing for the rotary blade of a wind generator. The rotating unit rotates the ring gear. The front disc is fixed to the ring gear. An emulating assembly emulates the rotary blade of the wind generator.;COPYRIGHT KIPO 2011
