Comparative analysis of the wave gear drive kinematic diagram for servo-type mechanisms

The paper considers wave gear drives as one of the most promising types of transmission gears for the automatic control systems. They provide a precise enduring accuracy, efficiency, and torsional stiffness in the case of minimum backlash, dimensional specifications, and weight. The paper introduces a design technique for the kinematic diagrams of wave gear reducers as the final stage of the electromechanical drive. The comparative analysis was carried out considering the following qualitative indicators: efficiency, mass moment of inertia, backlash, enduring accuracy, and torsional stiffness. Rational subdivisions of the total gear ratio between wave gears and gear trains at the input ofdifferent kinematic diagrams are recommended. This technique is tested within the interactive design system. It helps the designers solve the whole range of problems of analysis, synthesis and optimization.
