運動の仕様を重視した非円形歯車のピッチ曲線の設計方法

抄録

Little research has been done so far on the development of a simplified design technique for noncircular gears. Such a technique should take into consideration various kinematic constraints that exist in the noncircular gear pitch curve design process, to obtain appropriate gearing on the basis of a given angular velocity ratio curve. It seems that no generalized design technique has yet been established. This study used design specifications such as an angular velocity ratio curve (types of curves in individual segments and their coefficients) and center distance to design a pair of noncircular gears. The center distance was kept constant. The design process for the pitch curve was obtained and extracted from various kinematic constraints. Based on thses results, We developed a design automation technique for the pitch curve for noncircular gears, with given arbitrary angular velocity ratio curve.
