하이브리드 커빅 기어 최적설계 및 IRT기법을 적용한 건정성 평가

Abstract

The gear has played the important roles for long time as the one of representative mechanical elements together with bearing and screw since the industrial society. The gear not only plays the role of transmitting the power and is widely used as the one for the wrist watches in small size and turbine reduction gear for vessel in thousands of kw class, reduction device in automobile and aircraft, differential gear and wind power generator in large size but also its kind and usage are various even today. The gear that is developed in such various ways is developed to carry out the complex operations and its research and development are carried out in various types. The gear with such complex operations, special generation and shape is called as hybrid gear and its development is being carried out by the companies and academic society actively. Among these gears, hybrid CURVIC gear is an index of precision in machine tools in industrial society. In this paper, we prove the applicability and reliability of FEM analysis and infrared radiography for reliability improvement in hybrid CURVIC gear.
