On the basis of the modification theory, relative modification concept of cycloidal gear pair and the appraisal index of the initial backlash are built to solve the problem that cycloidal gear works unsmoothly in pin wheel of the full-hydrostatic steering control units. The major goal of modification is a uniformity of initial backlash, so equidistance modification that has good effect on improving quality of fluid cycloidal pair is chosen.
