Stiffness analysis, optimization and test verification are performed on a deceleratingmechanism. The effect of a pre-tensioning force of a ball screw and the gaps of each transmission pair isanalyzed, and the method of controlling the stiffness is analyzed, and a method for controlling factorsinfluencing the stiffness is proposed. The statics analysis of the decelerating mechanism is implementedby ANSYS, and a special testing device is designed and produced to test the stiffness of the deceleratingmechanism. The results indicate that, the design of the decelerating mechanism meets the stiffnessrequirement, and the method for testing the stiffness of decelerating mechanism is further provided.
