“…Under dry friction conditions, two damage modes including wear and fatigue were tested experimentally, and this will seriously affect the load capacity, transmission accuracy and service life of the PRSM. Blinov et al [88][89] measured the thread profile on the sampling length through a profiler. The test shows that the main errors include pitch deviations and thread profiles.…”

With the rapid development of all electric mechanical equipment in the fields of industrial application, aerospace engineering, and national defense, planetary roller screw mechanism has attracted much attention as a new type actuator of electro-mechanical actuator system. This report systematically reviews previous large number of researches as well as new advancements on five types of planetary roller screw mechanisms from both available literatures and studies presented. Firstly, the general structure, merits, limitations, and the application of five types of planetary roller screw mechanisms are summarized. Then, the development state of the planetary roller screw mechanisms is elaborated in the three aspects: parameter design, contact properties, and performance analysis. Common problems and tendencies of theoretical analysis and calculation models are analyzed. Finally, the research directions and methods in the future on planetary roller screw mechanism are discussed. Key technologies and research challenges are presented in terms of multi-pair dynamic contact and multi-body vibration of system, and the development prospects for various planetary roller screw mechanisms in all electric mechanical equipment are summed up.

A kinematic model of the planetary roller screw mechanism (PRSM) is proposed, which accounts for the run-out errors of the screw, roller, nut, ring gear, and carrier, and the position errors of the nut and the pinhole in the carrier. The roller floating region, which contains all the possible positions of the roller inside the pinhole, is obtained by analyzing the axial clearances between mating thread surfaces and the radial clearance between the roller and carrier. The proposed model is based on the constraint that the set of roller floating region is not empty. Then, the additional rigid-body movement on the nut is derived and the path of motion transfer from the screw to the nut is obtained. According to the fundamental property of rigid-body kinematics, the axial velocity of the nut is derived and the transmission error of the PRSM is calculated. The proposed model is verified by comparing the calculated transmission error with experimental one. The results show that the transmission error of the PRSM with run-out and position errors is cyclic with a period corresponding to the rotation period of the screw and the magnitude of the transmission error can be much larger than the lead error of the screw. Besides, due to the run-out and position errors, the roller can move radially or transversally inside the pinhole of the carrier when the elements in the PRSM are regarded as rigid bodies.
