초록

본 연구에서는 사이클로이드기어시스템 1단, 한 쌍의 평기어시스템, 입력 축, 출력 축, 하우징으로 구성되어 있는 2MW급 풍력발전기용 사이클로이드 피치감속기에 대해 유한요소해석을 통한 안정성평가를 수행하였다. 또한 평기어에 대해서는 ISO 6336에 의한 기어강도해석을 통하여 안정성 여부를 평가하였다. 2MW급 풍력발전기용 사이클로이드 감속기의 고유진동 특성 해석을 수행하였고, 입력축 질량불평형, 출력축 질량불평형, 평기어 치합전달오차, 사이클로이드기어 치합전달오차 등에 발생하는 가진원에 대해 위험속도 분석을 하였다.

In this paper, finite element analysis of a cycloidal pitch reducer for a 2 MW-class wind turbine is reviewed. The system is composed of one cycloid set, one spur gear set, an input shaft, an output shaft, and a housing. The system was also evaluated for stability by analyzing spur gear strength according to ISO 6336. An analysis of the natural vibration characteristics of the 2 MW-class wind turbine cycloid pitch reducer was performed with attention to critical speed with input mass unbalance, output mass unbalance, spur gear transmission error, cycloid gear transmission error, and excitation frequency.
