Design and Experimental Research of the Drive of an Automatic Control System with a Harmonic Drive

Enhancement of automatic control systems is impossible without designing modern drives that provide high accuracy, small reduced moment of inertia and high efficiency; and harmonic drives possess these qualities. This paper presents the design of an electromechanical actuator with a harmonic drive intended for automated control systems. Technical characteristics of the actuator as well as experimental stands, test methods and data processing technics are described. The results of experimental studies of the efficiency factor, backlash and torsional rigidity, gear ratio errors, vibration activity and frequency-response of the reducing gear are presented. The experimental results are compared with the results of similar studies performed on the actuators equipped with harmonic drives.
