Definitions

  • the invention relates to a hand-held rotary hammer or chisel hammer with the features according to the preamble of claim 1. (See, eg EP-A-1 252 976 ).
  • a hand-held hammer drill or chisel hammer with a hammer or hammer mechanism comprises a tool spindle with a chuck in which a tool insert is held, for example in the form of a drill or a chisel.
  • the invention has for its object to further improve a generic rotary hammer or chisel hammer in terms of reduced oscillating reaction forces in a small volume.
  • a hand-held rotary hammer or chisel hammer in which the repayment mass of the vibration damper is mounted resiliently movable within the gear housing on an axle component arranged there.
  • the repayment mass lies within the transmission housing in the immediate vicinity of the tool spindle and thus to the location of the vibration excitation.
  • the excitation and repayment forces cancel each other at least approximately at the place of origin.
  • a large part of the other components of the hammer drill or chisel hammer are outside of the power transmission path between the tool insert and the vibration damper and thus subject to a reduced vibration load.
  • the size of the vibrating masses is reduced, whereby the arrangement with high efficiency be made small and lightweight can.
  • Eccentricities between an excitation axis and a movement axis of the absorber are at least approximately avoided.
  • the arrangement within the gear housing requires no or at most only a small additional space. Overall, there is a high efficiency of the absorber and a reduced vibration load of the operator and the device itself.
  • the repayment mass is advantageously mounted axially displaceable parallel to the tool spindle. In this direction occur mainly the excitation vibrations.
  • the axially parallel storage of the repayment mass leads to a high degree of effectiveness.
  • a dedicated axle component For storage of the repayment mass, a dedicated axle component can be arranged.
  • the tool spindle performs an exclusive axial beating motion without being rotated.
  • a rotary drive for the tool spindle is not required.
  • an arrangement may be provided in which either a chisel hammer is provided as a purely axially movable tool spindle or alternatively for a hammer drilling operation a rotationally drivable tool spindle with an additional output shaft.
  • an embodiment is suitable in which the axle component is formed by the output shaft mounted in the gearbox housing.
  • the output shaft may be the tool spindle itself or a further gear shaft and is preferably a countershaft mounted axially parallel to the tool spindle.
  • the countershaft is used for torque transmission between a motor-side drive shaft and the tool spindle and can also be provided for the drive of the hammer mill. Their relative position to the tool spindle causes a high efficiency of the vibration without or with only slightly increased space.
  • the axis component is advantageously arranged together with the repayment mass in a direction perpendicular to the tool spindle height direction between the tool spindle and a center of mass of the hammer drill or chisel hammer. It has been shown that with the said arrangement, the transmission of oscillating residual forces on the center of gravity and thus on the guide hand of the operator are further reduced.
  • the repayment mass is held between two in particular pressure-biased springs.
  • the springs About the oscillating course of the oscillation path, the springs remain druckvorgespannt without a game-afflicted Last therapiess crisp occurs.
  • the spring behavior is at least approximately continuous or even linear. Rattling noises are avoided.
  • the repayment mass encloses the axle component in the form of a sleeve.
  • the repayment mass whose center of mass is on the longitudinal axis of the axle component without an eccentricity. It is given a tilting and tilting moment-free leadership of the repayment mass with a clean vibration behavior.
  • the repayment mass advantageously has an annular opening on the front side for, in particular, at least approximately complete reception of the spring.
  • the repayment mass overlaps the respective spring.
  • the component can be carried out correspondingly long stretched with a small diameter, without the frontal springs require additional axial space.
  • the smaller outer diameter of the repayment mass allows an arrangement, for example on a planned transmission shaft, without an adjustment of the transmission housing in the diameter direction is required.
  • the repayment mass is non-rotatably connected to the axle component.
  • the arrangement is simple and inexpensive in construction, in particular with regard to the axial spring support.
  • the repayment mass is rotatably mounted on the axle component. It may, for example, be provided that the axle component is a rotatable gear shaft, while the repayment mass itself does not rotate. The rotating masses and the consequent reaction moments and reaction forces are low.
  • a slide bearing sleeve is advantageously provided, which in particular has a stop for the spring for the elastic support of the repayment mass.
  • the plain bearing sleeve is insensitive to shock loads in hammer operation. In conjunction with the abovementioned attacks, the plain bearing sleeve, the compression springs and the repayment mass form an integral component which can be installed in a simple manner in a pre-assembled manner.
  • the co-rotating with the repayment mass sleeve bearing sleeve allows easy support of the compression springs without a rotating relative movement between the individual components.
