Based on the comprehensive study about the design requirements of the high order and denatured ellipse as section curve of the gear pair

the method of efficient acquiring the complex highorder denatured elliptic pitch curve is proposed

the simulation process of precise meshing of driving and driven wheels is achieved.The effects of the parameters of eccentricity ratio

denatured coefficient and order number of driven wheel on the periodicity and asymmetry of the transmission ratio curve are analyzed in detail.High-order and denatured elliptical gear pair combine with crank-slide mechanism

through researching the motion law of the combination mechanism

the specific motion output is obtained.Both theoretical research findings and experimental results show that the expected gear pair can be obtained by selecting and adjusting important parameters of the high order and denatured elliptical gear pair which is devised in accordance with the basic design conditions.
