HEAT TREATMENT METHOD OF YAW BEARING FOR WIND GENERATOR
摘要
<p>PURPOSE: A high frequency heat treatment of a yaw bearing for wind power generation is provided to minimize trial and error during the heating process of a gear part using high frequency heat treatment by limiting high frequency range, output, and conveying speed. CONSTITUTION: A high frequency heat treatment of a yaw bearing for wind power generation comprises following steps: installing a yaw bearing for wind power generation in a rotation table(S100); setting a value for a cooling unit and a high frequency heat treatment unit(S300); injecting high frequency between a pair of gears by operating the cooling unit and high frequency heat treatment unit and spraying cooling water(S400); relatively conveying the high frequency parallelly to the forming direction of the gear(S500); pausing the cooling unit and high frequency heat treatment unit and rotating the yaw bearing(S600); and sequentially and repeatedly performing heat treatment, injection part conveying, and bearing rotating processes for multiple times. [Reference numerals] (S100) Bearing installing step; (S200) Unit setting step; (S300) Set value designating step; (S400) Heat treatment step; (S500) Injection part transfer step; (S600) Bearing rotating step;</p>
