Abstract: With the rising application of double-nut planetary roller screw mechanism (PRSM) into industry, increasing comprehensive studies are required to identify the interactions among motion, forces and deformations of the ...

Abstract: Abstract. Transmission efficiency serves as a critical indicator for evaluating the performance of the planetary roller screw mechanism (PRSM). Existing prediction models, however, often exhibit significant deviations, ...

Abstract: A comprehensive contact analysis model to determine the contact positions and clearances of mating thread surfaces in the planetary roller screw mechanism (PRSM) is proposed in this paper. By introducing a three-dimensional ...

Abstract: 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 ...
