Movable axial element for a rotary tool dampening system
First Claim
1. A movable axial element for a damping system, the axial element comprising:
- a rectilinear absorbent mass positionable in a housing;
a plurality of annular grooves arranged on a periphery of the absorbent mass, each of the grooves housing an elastic element, each of the elastic elements being arranged to bear against an internal wall of the housing, each of the plurality of grooves including a base formed by a shoulder of the absorbent mass, the grooves having variable widths along a portion of the shoulder of the absorbent mass, wherein 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 axial element to form an adjusting device integrated into the movable axial element to enable the control of a prestressing exerted by the annular lip on at least one of the elastic elements mounted on the periphery of the absorbent mass, the prestressing being generated without rotation of the annular lip relative to elastic element; and
at least one movable edge formed by a sliding washer separating two juxtaposed grooves, the sliding washer having internal dimensions corresponding to dimensions of the shoulder of the portion of absorbent mass.

Abstract
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.

8. A vibration damping system for damping radial vibrations for a turning, boring, milling or machining tool mounted on a machine, the tool being movable in rotation relative to a machined part, the system comprising:
-
a hollow cylinder forming an axial housing; and a movable axial element included in the housing, the movable axial element including a rectilinear absorbent mass positionable in the housing and having a plurality of annular grooves arranged on a periphery of the absorbent mass, each of the grooves housing an elastic element being arranged to bear against an internal wall of the housing, each of the plurality of grooves including a base formed by a shoulder of the absorbent mass, the grooves having variable widths along a portion of the shoulder of the absorbent mass, wherein 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 axial element to form an adjusting device integrated into the movable axial element to enable the control of a prestressing exerted by the annular lip on at least one of the elastic elements mounted on the periphery of the absorbent mass, the prestressing being generated without rotation of the annular lip relative to elastic element, and at least one movable edge formed by a sliding washer separating two juxtaposed grooves, the sliding washer having internal dimensions corresponding to dimensions of the shoulder of the portion of absorbent mass. - View Dependent Claims (9)
