Jiaxing PeiThe cycloid gear wear of RV reducers leads to the degradation of the industrial robots’ transmission accuracy, but the degradation law with respect to the wear volume is still unclear. In this paper, a method for determining transmission error (TE) through a combination of numerical and simulation analysis is proposed. The wear model of cycloid gear was ascertained based on the theory of Archard. Then, the full rigid body and rigid–flexible coupling model of RV reducers were established using the multibody dynamics theory. Finally, the static transmission error (STE) and dynamic transmission error (DTE) were investigated. The results show that as working hours increase, the cycloid gear wear volume increases, and transmission accuracy deteriorates, but the rate tends to slow down.

In this paper, the application scope of the average flow model is extended to grease lubrication considering the non-Newtonian characteristics. First, flow factor expressions applicable to both Newtonian fluids and non-Newtonian fluids are derived. Then, a model problem is established by coupling the Reynolds governing equation, film thickness function, and boundary conditions and solved for the flow factor. Fit the result into empirical relations for conveniently using in the grease lubrication analysis. Finally, the influence of several parameters on the flow factor is studied. The results demonstrate that the film thickness ratio, rheological index, and surface elastic deformation have a significant effect on the flow factor, and the influence law is affected by the orientation of the surface roughness.
