A MAGNETORHEOLOGICAL FLUID DAMPER FOR BORING BARS

摘要

The present invention relates to A fluid damper (1) for increasing the stability of boring bars characterized by; at least one foam layer (2) filled with magnetorheological fluid, suitable to be wrapped around a boring bar (B); at least one bobbin (3) having at least two flanges, each of the flanges having at least one hole for allowing the said boring bar (B) and the foam layer (2) to pass through, the flanges being connected to each other by a hollow connecting member, the bobbin (3) flanges being placed so as to define a space between them; at least one electromagnetic coil (4) placed in the space defined by the bobbin (3) flanges, having at least one hole for allowing the boring bar (B) and the foam layer (2) to pass through, the electromagnetic coil (4) being suitable for producing magnetic flux lines passing through the foam layer (2) when energized, thereby changing at least one physical property of the foam layer (2); at least one casing (5) for covering the bobbin (3) and the electromagnetic coil (4).
