“…In order to make the PRSM load distribution uniform, Yao et al 77 simulated the spatial motion trajectories of screws-rollers-nuts and analyzed the stress cycle characteristics of threaded teeth of each part, based on the kinematics theory. Yao et al 78 then developed an optimization model for a multi-stage progressive PRSM, achieving a uniform load distribution and reduced contact stresses by considering both rolling-sliding friction and reduced axial clearance. Liu et al 79 presented a technique for thread engagement that relies on the convex and concave nature of threaded teeth, and conducted an investigation into the effects of specific parameters on the engagement gap and load distribution.…”

The planetary roller screw mechanism, a novel high-performance electromechanical servo drive component, holds a central position in leading-edge equipment, attracting significant attention within the engineering community. This paper conducts a comprehensive review of current research and recent breakthroughs in the analysis of errors and transmission characteristics associated with the planetary roller screw mechanism. Drawing on the unique attributes of this mechanism, the analysis of errors is undertaken from two distinct angles: motion errors and machining errors. A foundational examination of the bearing characteristics of this mechanism serves as the cornerstone for assessing its transmission properties. The report delves into the impact on transmission performance from the perspectives of both accuracy and efficiency. In this study, each model and related literature are exhaustively described and examined in detail. Furthermore, we critically evaluate the key discoveries emanating from various models and numerical simulations, shedding light on potential future directions in the realm of errors and transmission characteristics of the planetary roller screw mechanism.
