| Abstract: | Stiffness analysis, optimization and test verification are performed on a decelerating mechanism. The effect of a pre tensioning force of a ball screw and the gaps of each transmission pair is analyzed, and the method of controlling the stiffness is analyzed, and a method for controlling factors influencing the stiffness is proposed. The statics analysis of the decelerating mechanism is implemented by ANSYS, and a special testing device is designed and produced to test the stiffness of the decelerating mechanism. The results indicate that, the design of the decelerating mechanism meets the stiffness requirement, and the method for testing the stiffness of decelerating mechanism is further provided. |
