摘要： The roller screw mechanism is provided with a screw including an external thread, with a nut arranged about and coaxial with said screw, the nut including an internal thread, and with a plurality of rollers inserted between the screw and the nut and each including an external thread engaging the external and internal threads of said screw and of said nut. The screw is axially moveable in relation to the rollers. The flanks of the thread of the screw have a concave profile in cross section.

摘要： The roller screw mechanism is provided with a screw comprising an external thread, with a nut arranged around and coaxial with the said screw, the nut comprising an internal thread, and with a plurality of rollers interposed between the screw and the nut and comprising flanks interacting with the said threads. The value of the opening angle α of the flanks of the external thread of the screw is greater than the value of the opening angle of the flanks of the rollers.
