Because of low cost and accurate transfer characteristic, timing belt drives are widely used in servo systems such as industrial robots and office automation equipments. ln the servo systems, high performances are required for high productivity and quality of goods. High stiffness of drive system is expected in timing belt drives. We propose a method to estimate the torsional stiffness of the belt drive by using tensile experimental results. First, the torsoinal stiffness is analytically derived from shaft load and tensile stiffness when the driving and driven pulleys have the same radii. Next, in the case of different radii (reduction system), the relation between the shaft load and the torsional stiffness is analyzed by the same approach. Finally, tensile and torsional experiments are carried out. lt is confirmed that the analized results are in good agreement with the experimental results.
