EXPERIMENTAL DETERMINATION OF KINEMATIC PRECISION OF POSITIONING OF A DOUBLE HARMONIC TRANSMISSION

Abstract

The paper presents the results of the experimental researches performed on a double harmonic transmission, regarding the determination of the kinematic precision of positioning of the respective transmission. The experimental investigations aimed to study the influence of the variation of the torsion moment from the output shaft of the double harmonic transmission and of the reversing of the direction of rotation of the input shaft on the transmission ratio and of the kinematic precision of the positioning of the transmission. The experimental results have shown that the double harmonic transmission, with the short flexible toothed wheel, has a kinematic precision of positioning higher than that known from the simple radial harmonic transmissions.
