Title: The Innovative Mind of Jean-Emile Chollet
Introduction
Jean-Emile Chollet, an inventive engineer based in Archamps, France, has made significant contributions to the field of vacuum pump technology. With a focus on enhancing the reliability and efficiency of mechanical systems, Chollet holds two patents that showcase his innovative approaches to engineering challenges. His work is characterized by a blend of technical expertise and a commitment to improving industrial processes.
Latest Patents
Chollet's most recent patents include a damper system and a bearing centering device specifically designed for magnetic bearing vacuum pumps. The damper system utilizes a unique configuration where the rotor is suspended inside the stator using radial magnetic bearings. This innovative design limits radial movements through one or more landing mechanical bearings, which consist of both rotor and stator rolling bearing races. A coaxial ring of elastomer in the shape of a torus is strategically placed between the stator rolling bearing race and the stator itself, creating a damped elastic connection. This advancement significantly enhances the reliability and service life of the landing mechanical bearing.
In addition, Chollet has developed a spacer of adjustable thickness for turbomolecular pumps. This invention comprises a stack of parts, such as the stator disks, alternately spaced with knife-shaped deformable portions. Upon initial installation, the deformable portions compress to accommodate tolerances between surfaces defined by the pump body and casing. This innovation eliminates the need for time-consuming adjustments and re-machining, simplifying the installation process of stator assemblies.
