The planetary roller screw（PRS） is a mechanical transmission device that converting rotary motion into linear motion or vice versa

and it now has become the domestic and foreign research focus because of its characteristics of high-thrust

high-precision

high frequency response

and long life with the future development of all-electric aircraft and all-electric weapon

besides

the petroleum

chemistry industry and machine tool are also requirement.The basic working principle of PRS

the characteristics of five kinds of existing structure

application area and the most probable failure modes of PRS are introduced

and the research status and developmental trend of PRS from the aspects of the structure design

mechanics analysis and production manufacture are also summarized.Based on the summaries and related analysis

some suggestions are presented for future PRS research and development.
