사이클로이드 기어 설계 및 가공에 관한 연구

In this paper, a practical method for design and machining of cycloid gear was investigated. Based on the proposed method, a systematic program was developed for automatically designing the tooth profiles of epicycloid and hypocycloid gears for the case of one difference between the number of teeth of cycloid gear and the number of pins. In addition, this program produces NC-code for cycloid gear by Biarc curve fitting using position coordinates of tooth profiles and pressure angles. The error analysis between cycloid curve and Biarc curve was performed to show the effective method of equidistant partitioning of cycloid curve so that efficient method of Biarc curve fitting was also proposed for the partitioned curve.
