A movable element for a damping system includes an absorbent mass arranged to be positioned in a housing. At least two adapted portions are arranged on a periphery of the absorbent mass. A plurality of elastic elements are arranged in the adapted portions and are designed to bear against an internal wall of the housing. The elastic elements have optimum damping properties in different variation ranges of at least one parameter. The present invention further relates to a damping system.

Movable element and a damping system

A movable axial element for a damping system includes a rectilinear absorbent mass positionable in the housing and having at least one annular groove arranged on a periphery of the absorbent mass and in which at least one elastic element is arranged to bear against an internal wall of the housing. The at least one groove includes a base formed by a shoulder of the absorbent mass. An edge formed by a structure bearing an annular lip is mounted in a sliding manner on at least one part of the shoulder along at least one axis of the movable element to form an adjusting device integrated into the movable element to enable the control of a prestressing exerted by the annular lip on the elastic element mounted on the periphery of the absorbent mass, the prestressing being generated without rotation of the annular lip relative to elastic element.

An assembly for tightening and securing includes a first male part and a second female part fitted together, which have complementary forms. The fitting includes at least one contact surface of the first part with the second part. The assembly also includes at least one annular means mounted on the periphery of one of the two parts. The annular means is connected in a translational manner to the part on which the annular means is mounted when the annular means abuts with the part on which the means is mounted, and arranged to interact with a peripheral surface of the complementary part during a rotation of the annular means in relation to the complementary part.

A damping tool holder, such as a boring head, a chuck, or a milling cutting arbor, integrates a damping device (), in the form of an elongated body. The damping device () is housed in a mounting body (), connected by one end to the tool-holder body () and having at its other end an end fitting () for mounting a tool, whereby the mounting body () is equipped with at least one lubricant feed pipe (), emptying at its front end into the end fitting () for mounting a tool and connected at its other end to a circular groove () for distributing lubricant that is provided on the front surface of the tool holder ().

Tool holder such as a boring head, a chuck, or a milling cutting arbor integrating a damping device

The present invention relates to a tool holder, such as a reaming head (), or a milling arbor, provided with a damping means () in the form of an elongated body, which is arranged in an end compartment () of the tool holder (), which compartment is of appropriate shape and size, and closed at its end by a body () for receiving a reaming head or by a milling element. Tool holder characterized in that the damping means () is of the type presenting only radial absorption, and it is provided with at least one elastically deformable means (), at least close to each end, where said elastically deformable means () extend between the envelope of the damping means () and the wall of the compartment () of the tool holder (), and are clamped between the wall of the compartment () and the damping means (), and where the ends of the damping means extend in the compartment () without stress. The invention is applicable more particularly in the field of accessories for machine tools, with digital control, machining centers, flexible cells and workshops.
