Abstract
1525145 Vibration damped percussion tool ATLAS COPCO AB 27 Sept 1976 [9 Oct 1975 4 Feb 1976] 39986/76 Heading B4C An impact tool 11 includes a vibration damper comprising an envelope 13 which surrounds part of the tool and encloses a liquid for damping lateral vibrations of the tool. The tool is adapted to be received and subject to repeated blows in, e.g. a concrete breaker or a rock drill. The liquid may be a silicon oil or grease or an unvulcanized silicon rubber and may contain iron powder or dissolved or dispersed polymer. It may harden on contact with oxygen or moisture in order to seal any hole formed in the envelope. The envelope may be double-walled so that the liquid does not contact the tool. The envelope may be of rubber or steel. In the embodiment of Fig. 8 the liquid 130 is contained within a bag 132 which is wrapped around the tool and in turn enclosed by envelope 130. The bag is divided into 3 by 2 transverse welds (135, Fig. 11, not shown) to prevent the liquid concentrating at the bottom of the bag. Annular springs 131 urge internal ribs 137 of the envelope into recesses 121 in the tool so as to secure the envelope. Collar (114, Fig. 6, not shown) may be secured to the tool by annular spring (141. Fig. 7, not shown).
