Pure Torque Reaction System for Wind Tubine Gearbox

순수 토크 전달을 위한 풍력발전기용 증속기 반력지지 장치

Gearbox is used to converter the power with high torque and low speed into the power with low torque and high speed. Gearbox housing should be sustained to prevent rotation of gearbox itself due to the difference between input and out torque. Uneven wind causes the reaction system to have unwanted reactive loads together with predictable pure torque. These unwanted reaction loads often cause the failure of gearbox due to bad gear mesh. In this paper, pure torque reaction system is proposed to prevent the failure of gearbox. Effectiveness and functionality of the proposed reaction system are demonstrated through the numerical analysis.
