Definitions

  • the invention refers to a tool holder for a mechanically driven at least partially striking tool such as chisel or percussion drill with a radially displaceable locking body.
  • Such impact tool receptacles have, a radially displaceable locking body for radial engagement in locking grooves of the insertion end radially outwardly locking locking means.
  • the object is to realize a vibration-proof impact tool holder, in particular with respect to the locking body.
  • a tool holder for an at least partially impact driven tool with a radially displaceable locking body on this radially outwardly locking locking means which is at least on the locking body radially facing locking surface radially attenuating.
  • the locking surface consists of a material which has a maximum of the imaginary portion of the complex Elasizticiansmoduls in the temperature range between 0 ° C and 100 ° C and in the frequency range between 1 Hz and 100 Hz, which is achieved with this damping material in the intended application optimum damping ,
  • the locking surface is formed radially elastic, more advantageously made of elastomer such as rubber or silicone rubber, whereby there is a damping contact with the locking means even with strongly radially oscillating locking bodies.
  • the locking surface is softer than the Verrieglungselasticity formed, further advantageous with a Shore A hardness of 80 to 95, whereby the locking body are embedded in accordance with the HERTZschen pressure over a large, damping contact surface in the locking means.
  • the locking means is rotationally symmetrical, further advantageously sleeve-shaped or annular, whereby the locking forces are absorbed by ring forces.
  • the locking means is formed in two parts material, wherein the radial inner part forms the locking surface, whereby the inner part is separately optimized with respect to the damping.
  • the radial thickness of the inner part is between one fifth and the simple of the radial extent of the locking body, whereby a sufficiently deep damping bedding of the inner part is possible.
  • the inner part is designed as a damping ring, whereby the locking forces can be absorbed via annular forces.
  • One of these locking balls radially outward locking, approximately annular, from the outside manually axially displaceable locking means 5 + 6 has a locking body 3 radially facing locking surface 4.
  • the locking means 5 + 6 itself is materially formed in two parts, wherein the radial inner part 5 forms the locking surface 4 in the form of a damping ring and the axially displaceable outer part 6 consists of metal.
  • the radial thickness of the damping ring of elastic silicone rubber of a Shore A hardness of 90 with a maximum of the loss modulus at 50 ° C and 10 Hz is one third of the radial extent of the locking balls.
