Definitions

  • the invention relates to a vibration damper for a tool such as a hammer drill, a chisel hammer or similar.
  • the invention is based on the object, a vibration damper to create the vibrations transmitted to the operator reduced.
  • the sprung arranged mass body allows a good damping occurring vibrations.
  • a mass body in particular an existing component of the tool is used.
  • an additional mass body the weight increase of the tool would be avoided.
  • vibration damping it may be appropriate to have an additional mass body to use vibration damping.
  • This one is in a separate one Housing spring mounted.
  • the arrangement of the vibration absorber in a separate housing allows easy Retrofitting to existing tools. simultaneously can by the resilient suspension of a mass body in the Housing of the vibration damper a good damping occurring Vibrations of the tool can be achieved.
  • the vibration damper has a device for Fixation on the housing of a tool.
  • the housing of the vibration damper positive or non-positive fixable on the tool. This can be a easy retrofitting to existing tools, without the need for modifications to the tool itself.
  • the vibration absorber is in a position fixable to the tool, in which the direction of movement of the mass body parallel to the longitudinal axis of a Tool arranged tool insert is located.
  • the main vibration can be damped. Too too Is to be able to dampen vibrations in other directions is provided that a mass body in two or three directions of movement movable and opposite the housing of the vibration absorber is stored sprung. The mass body can thus attenuate multiaxial superimposed vibrations.
  • the tool 1 is in particular a drill and chisel hammer.
  • the tool 1 has a housing 2, on which a handle 3 is formed is. In the handle 3 opens a line 7 to the supply of the electric tool 1 with power.
  • the tool 1 on an operating lever 4.
  • a tool holder 5 is provided in the one Tool insert 13 can be arranged.
  • On the housing 2 is a selector lever 6 is provided, with which the operating mode of the tool 1 can be switched.
  • the tool bit 13 is rotating about the longitudinal axis 14 or striking in the direction of the longitudinal axis 14 or with a combined rotating and beating movement driven.
  • a vibration damper 8 is arranged on the housing 2 of the tool 1.
  • This consists of a housing 9 in which a mass body 10 is arranged.
  • the mass body 10 is in the direction of movement 12 movably mounted.
  • the mass body 10 is supported in the direction of movement 12 by a spring 11 the housing 9 of the vibration absorber 8.
  • the mass body 10 consists in particular of hard metal. It can, however other materials, especially heavy materials, be appropriate.
  • the mass body 10 may consist of several individual Be formed components.
  • the spring shown schematically 11 can also be composed of several individual feathers be.
  • the housing 9 of the vibration absorber 8 is on the housing 2 of the Tool 1 releasably fixed.
  • the fixation can be force-locking or be positive.
  • the vibration absorber 8 means for fixing to the housing 2 of the tool. 1 on.
  • the mass body 10 in two or three directions of movement is movable. In particular, lie The directions of movement are perpendicular to each other, so that Vibrations can be damped in any direction.
  • the mass of the Mass body 10 and the spring constant of the spring 11 on the Vibration of the tool 1 tuned.
  • several mass body in the housing 9 of the vibration absorber 8 to arrange, each movable in other directions of movement are stored.
  • a separate vibration absorber each with a movably mounted mass body as well to provide a spring.
  • the spring constant of the spring 11 adapted can be.
  • mass body suitable components of the tool such as the oil cooler used and resiliently mounted relative to the housing of the tool.
  • the mass body should advantageously have a weight of 5% up to 10% of the weight of the tool.
  • By use existing components are only the springs as additional mass needed.
  • the mass body is advantageous made of a heavy material, such as carbide. As a result, a compact design can be achieved.
  • the vibration damper is a multi-axis absorber educated. Especially with pneumatic hammers with wobble drive or crank drive vibrations occur in multiple axes on. Through a two- or three-axle vibration absorber An increased vibration reduction can be achieved.
  • the absorber is designed as a retrofittable absorber. This can be a vibration reduction with existing tools be achieved by up to 50%.
