“…At present, domestic and overseas scholars have made many deeply research on cycloid ball planetary transmission, including structure principle [1, 2], engagement principle [3], mechanical property [4, 5], and transmission accuracy [6, 7]. However, the dynamic analysis of it has rarely been reported.…”

The vibration of robot joint reducer is the main factor that causes vibration or motion error of robot system. To improve the dynamic precision of robot system, the cycloid ball transmission used in robot joint is selected as study object in this paper. An efficient dynamic modelling method is presented—lumped stiffness method. Based on lumped stiffness method, a translational–torsional coupling dynamics model of cycloid ball transmission system is established. Mesh stiffness variation excitation, damping of system are all intrinsically considered in the model. The dynamic equation of system is derived by means of relative displacement relationship among different components. Then, the natural frequencies and vibration modes of the derivative system are presented by solving the associated eigenvalue problem. Finally, the influence of the main structural parameters on the natural frequency of the system is analysed. The present research can provide a new idea for dynamic analysis of robot joint reducer and provide a more simplify dynamic modelling method for robot system with joint reducer.

“…The cycloid ball planetary drive need an equal speed output mechanism (W mechanism) to transfer the movement and power from planetary plate to the output plate or shaft [2] . In order to ensure the important character of the drive with non-backlash, NBRGEO mechanism is adopted as output mechanism of this drive [3,4] . The force analysis has important effect on the drive system's reliability, stability, optimum design and so on.…”

Precision ball planetary drive is mainly composed of non-backlash cycloid ball reduction speed mechanism and non-backlash ball ring groove equal speed output mechanism (NBRGEO mechanism or called W mechanism). The three-dimension contact force is analyzed. The nonlinear mechanics model of NBRGEO mechanism was established. The formulas of contact force and stress were deduced. A numerical example is intended to illustrate the presented method of contact force analysis by using of computer program. Therefore, the contact force and stress distributing characteristics of NBRGEO mechanism is acquired. The research results offer theoretical basis for the design of NBRGEO mechanism of the precision ball planetary drive and the research of other precision planetary transmission.
