越野车双联非圆行星齿轮差速器的设计

Abstract

A new type of noncircular planetary differential is put forward for realizing the variable proportional distribution torque onto its two output axes,increasing the anti-skid function of differential and help to improve passing capacity for off-road vehicles.By analyzing transmission principle,the design method of pitch curves are given,and with involute tooth profile as a case,the parametric design program of non-circular gears is achieved to speed up planetary differential design with all sorts of parameter.Several kinds of new differential schemes are compared by structure,driving ratio and production process,which also shows the effectiveness of the new differential.
