RESEARCH OF TORSIONAL STIFNESS OF HARMONIC GEAR WITH INTERMEDIATE ROLLING BODIES

Abstract

The work is devoted to the urgent problem of developing mechanisms based on wave transmission with intermediate rolling elements (HGRE), which has high specific mass–dimensional parameters, which is especially important for its use in aircraft drive systems. Analytical dependences are obtained that make it possible to calculate the torsional stiffness of HGRE in the multiplier and reduction gear modes. The periodic value of the change in torsional stiffness is determined, due to the relative position of the HGRE elements, namely, the angular position of the wave–former relative to the hard wheel. The results of experimental studies of the torsional stiffness of HGRE are presented, which confirm the periodic value of the change in torsional stiffness of HGRE
