WEAR RESISTANT STRUCTURE OF MOVING VANE

摘要

PROBLEM TO BE SOLVED: To provide a wear resistant structure of a moving vane in which the wear resistance of its wind-ripping part is improved and its service life is prolonged inexpensively without increasing its weight. SOLUTION: A wear resistant covering material 10 made of butadiene-based rubber having a Vickers hardness of 60 to 70 is adhered to the wind-ripping part 9 of the rotation driven vane 8.
