TESTING APPARATUS OF SHRINK DISK FOR WIND TURBINE

摘要

PURPOSE: A test apparatus for a shrink disk of an aerogenerator is provided to determine the maximum fastening force or failure of a shrink disk. CONSTITUTION: A test apparatus for a shrink disk of an aerogenerator comprises a base plate(100), a hub(200), a spindle(300), and a moment arm(400). The hub is projected from the top of the base plate, and has a circular space formed by recessing the top thereof and a supporting part(220) on the outer periphery to support a fitted shrink disk. The spindle has a lower outer periphery in a cylindrical shape to be inserted in the space of the hub. The moment arm is fixed to the top of the spindle in order to apply torsional torque to the spindle, and has a vertical coupling groove(410) for connection with the top of the spindle and side coupling grooves in which coupling plates(500) formed with respective loading rods(510) are inserted.
