The Match Design of the Belt-type or Chain-type CVT’s Cone Discs and Flexible Members 2004-40-0058

The paper aims at the axial deviation and twists of the middle flexible member when using the straight generatrix cone disc, and puts forward a match design methods of the cone disc and the flexible member. The method is to choose a curve with simple shape and can be processed easily as the profile of the flexible members, and calculating it’s conjugate curve as the cone disc’s generatrix according to the principle of conjugate curve and the constrain condition of the flexible members’ parallel moving along the shaft as a whole. The method avoids the flexible member’s axial deviation when transmitting on design principle. The paper brings forward the equations and computation example of the cone disc generatrix which matches the flexible member with arc curve profile and the one with line and arc combined curve profile, and analyses the value of the design parameter and it’ influence on the transmission performance.
