Title: Eric Allegri: Innovator in Roller Screw Mechanisms
Introduction
Eric Allegri is a notable inventor based in Montmélian, France. He has made significant contributions to the field of mechanical engineering, particularly in the development of roller screw mechanisms. With a total of 4 patents to his name, Allegri continues to push the boundaries of innovation in his industry.
Latest Patents
Among his latest patents is the "Roller screw mechanism and associated manufacturing method." This invention features a screw with an outer thread and a nut that is coaxially disposed around the screw. The nut contains an inner thread, and a series of rollers are positioned radially between the screw and the nut. Each roller is equipped with an outer thread that engages with both the outer and inner threads of the screw and nut, along with two outer gear teeth. The mechanism also includes synchronizing gear teeth that interact with the gear teeth of the rollers. Notably, the outside diameter of each gear tooth is less than the diameter of the roller's thread root, ensuring efficient operation.
Another significant patent is the "Method of manufacturing the thread of a nut in a screw and nut system." This method involves a two-stage process for creating a nut. The first stage focuses on material removal to form an internal thread with a nominal diameter that is lower than the desired final diameter. The second stage employs plastic deformation to achieve the predetermined final value through material displacement.
