摘要 |
<p>A device for the driving of a drilling and/or percussion tool provided with a spindle 5 mounted rotatably in the housing 1, the one end of which spindle is suitable for fastening to the tool piece, the other end being accessible to an oscillating percussion body 6 movable in the housing 1 by means of a guideway 7, a rotatable driving shaft 3 bringing the tool spindle into rotation, a transmission being provided with means for the conversion of the rotary motion of the drive shaft into an oscillatory motion of a drive member 8, said member being joined to the percussion body through an elastic member 26 having a non-linear spring characteristic, wherein the drive member is mounted on the drive shaft or a shaft coupled therewith, under an angle deviating from 90 degrees to the centre line thereof, and the elastic member is a plate-like member rotatably connected to the drive member, and being provided with a coupling means engaging with the percussion body, whereby the conversion mechanisme can be made simple and small, whilst the frequency of the oscillatory motion can be boosted considerably giving a better percussion effect on the tool spindle.</p> |
