ROTOR TEST APPARATUS FOR GEARLESS WIND POWER PLANT TURBINE

摘要

The present invention relates to a test device for testing a rotor used in a gearless wind turbine. The test device comprises a bed; multiple load cells evenly arranged on the bottom of the bed; a spotter protruding from the center part of the bed and having multiple coupling holes formed along the edge; a slewing ring bearing which comprises an inner ring part placed on the spotter and having multiple coupling taps corresponding to the coupling holes to connect with the spotter, and an outer ring coupled to the inner ring part to be rotated and having a gear formed on the outer surface and multiple first coupling holes vertically penetrated along the edge; a driving motor arranged close to one side of the spotter; a pinion connected to the rotary shaft of the driving motor and engaged with the gear of the outer ring part; and a connector which has multiple second coupling holes formed on a bottom flange corresponding to the first coupling holes and multiple third coupling holes formed on a top flange, and in which the bottom flange is coupled to the top of the outer ring part through the first and second coupling holes by bolts. The present invention can test the rotation characteristics of a rotor by operating the driving motor after an object to be tested is placed and fixed on the top flange of the connector.
