    摘要: A roller screw mechanism comprising a screw having an outer threading, a nut arranged around and coaxially to the screw, the nut having an inner threading, and a plurality of mutually identical rollers interposed between the screw and the nut. Each mutually identical roller having an outer threading engaged with the outer and inner threadings of the screw and of the nut. The threading of each roller being prolonged axially at each end by teeth respectively engaged with teeth of two annular gear wheels fixed in an unthreaded part of the bore of the nut. Each of the mutually identical rollers comprises an angular visual positioning feature, making it possible to place the rollers in one of the annular gear wheels with respect to a predetermined reference point of the gear wheel.

Each mutually identical roller having an outer threading engaged with the outer and inner threadings of the screw and of the nut. The threading of each mutually identical roller being prolonged axially at each end by teeth respectively engaged with teeth of two annular crown rings fixed in an unthreaded part of the bore of the nut. Each of the mutually identical rollers comprises an angular visual positioning feature. The nut comprises an angular visual positioning feature making it possible to angularly place the rollers in the crown ring.
