Description

풍력발전용 링기어의 열처리장치{Heat treatment apparatus of the wind power ring gear}TECHNICAL FIELD [0001] The present invention relates to a heat treatment apparatus for a wind power ring gear,

본 발명은 풍력발전용 링기어의 열처리장치에 관한 것으로서, 더욱 상세하게는 회전테이블에 안착된 링기어를 승강부에 의해 간편하게 상하로 승강시켜 가스를 연소시키는 화염발생부와 냉각수분사부에 접촉시켜서 열처리함으로써 링기어의 열처리를 효율적으로 실행하여 내구성이 향상되고 열처리 비용과 시간을 절감할 수 있게 한 풍력발전용 링기어의 열처리장치에 관한 것이다.
The present invention relates to a heat treatment apparatus for a ring gear for a wind power generator, and more particularly, to a ring gear for a wind power generator, in which a ring gear mounted on a rotary table is easily lifted up and down by a lift unit to contact a flame generating unit And more particularly, to a heat treatment apparatus for a ring gear for a wind power generator which is capable of efficiently performing heat treatment of a ring gear by heat treatment to improve durability and reduce heat treatment cost and time.

일반적으로 링기어의 열처리장치는 크게 수평상에서 이송하면서 열처리 하는 수평형 고주파 열처리장치와 수직으로 이송하면서 열처리 하는 수직형 고주파 열처리장치로 나눌 수 있다.Generally, the heat treatment apparatus of the ring gear can be divided into a horizontal type high frequency heat treatment apparatus which is heat treated while being horizontally transferred, and a vertical type high frequency heat treatment apparatus which is heat treated while being vertically transferred.

근래에 들어서는, 전자의 수평형 고주파 열처리장치는 소재를 열처리 함에 있어 보다 냉각공정이 용이하지 못해 수직형 열처리장치를 많이 사용하고 있는 실정이다.In recent years, a horizontal type high frequency heat treatment apparatus for electrons has been used in a vertical type heat treatment apparatus because the cooling process is not easy to heat the material.

뿐만 아니라, 이러한 수직형 열처리장치도 열처리 될 소재의 특징에 맞게 다양한 구조와 형상을 가지게 된다.In addition, such a vertical heat treatment apparatus has various structures and shapes to match the characteristics of the material to be heat-treated.

이 중에서 풍력발전용 링기어의 기어치를 열처리하는 수직형 열처리장치는 통상 회전 작동되는 회전테이블과 고주파 및 냉각수를 발생하는 가열/냉각수단으로 구성되어져 회전테이블 상부에 링기어를 안치시킨 후 가열/냉각수단으로부터 공급되는 고주파로써 열처리를 수행하게 된다.Among them, the vertical type heat treatment apparatus for heat-treating the gear teeth of the ring gear for wind power generation comprises a rotary table which is usually rotated and a heating / cooling means for generating high frequency and cooling water, And the heat treatment is performed with the high frequency supplied from the means.

그러나, 종래의 고주파 타입의 링기어 열처리장치는 구조가 복잡하고 비용이 많이 드는 문제점이 있었다.
However, the conventional high frequency type ring gear heat treatment apparatus has a problem in that the structure is complicated and the cost is high.
