Abstract
1391388 Boring bars; chucks REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 10 May 1973 [28 July 1972] 22327/73 Headings B3B and B3C [Also in Division F2] Vibrations of a rotating shaft, e.g. a toolholder or boring shaft 2 are damped by a body 7 in mercury 8 in an axial cavity 4 in the shaft. The cavity may be situated ahead of or behind the boring head. The body 7 is a cylinder of steel or heavy sintered metal, whose density is less than mercury. As the shaft rotates, the mercury is displaced by centrifugal force to the periphery of the cavity and centres the body. The body 7 has annular peripheral recesses 9 (Fig. 2) to increase the area of contact between it and the mercury to increase the damping due to friction. The area of contact can be varied by filling the space between the cavity walls and the body with mercury to a greater or lesser degree, but preferably the space is completely filled.
