The present invention relates to a support (1) for rolling bearings, which advantageously finds application, among others, in the technical field of rotary vacuum pumps, such as turbomolecular vacuum pumps. According to the invention, the support for rolling bearings (1) comprises a first inner annular shell (3) made of metal and intended to be mounted on the outer surface of a rolling bearing, a second outer annular shell (5) made of metal, concentric with said first inner annular shell and external thereto and intended to be mounted on the surface of the bearing seat, and an intermediate elastomeric member (7) provided between said inner and outer shells and fixed thereto. Thanks to the configuration of the invention, any relative movement between the metal shells (3, 5) and the intermediate elastomeric member (7) is prevented, while allowing movement of the first inner shell (3) and the second outer shell (5) relative to each other, so that the radial and axial stiffness of the support only depends on the mechanical properties and geometry of the intermediate elastomeric member (7). When supports (1) are applied to the rolling hearings (21) supporting the rotating shaft of a rotary vacuum pump, the vibrations coming from said rotating shaft and from the pump rotor associated thereto can be effectively damped and the dynamic behavior of said rotating shaft and of said pump rotor associated thereto can be reliably predicted.
A support for rolling bearing comprising:
A rolling bearing comprising an inner ring and an outer ring in which respective tracks for rolling elements are provided, provided with a support comprising
A rotary vacuum pump comprising:
