In this paper, we introduce the outline of the conic roller screw mechanism, a new device for converting rotary motion to linear motion, and report on its infinitesimal slip design. The mechanism achieves higher durability than that of ball screws by reducing Hertzian stress on rolling contact and also maintains high mechanical efficiency by minimizing partial slip on the contact line. Partial slip minimizing theory and method for accurate estimation of slip velocity are described in detail. Results of efficiency estimation shows that the roller screw mechanism has good efficiency comparable to ball screws.
