STUDY ON THE GEAR WHICH ITS PITCH CURVE IS CHANGED AS COSINE RULE CONJUGATE WITH THE NON-CIRCULAR GEAR

Abstract

Abstract: A kind of new type non-circular gear transmission is advanced. In which, one non-circular gear’s pitch curve is changed according to cosine rule, another conjugate with it. The basic parameters of non-circular gear are determined, such as primary circle, eccentricity ratio, eccentricity throw and proportional coefficient of center distance. The polar equation of non-circular gear pitch curve, calculation method of center dis-tance, formula of pitch curve length, primary circle radius and pressure angle is given. This kind of gear has been used in prac-tice and achieved good results.

Key words: Basic parameter, Calculation method, Conjugate, Non-circular
