Definitions

  • the invention relates to a hammer drill or chisel hammer with a striking mechanism, a housing surrounding it and a handle connected to the housing.
  • strikes are periodically generated using a striking mechanism and these are introduced onto the shank of a tool.
  • the periodic generation of impacts also leads to periodic shock loads in the housing, which stimulate it to oscillate or vibrate.
  • the vibrations are transmitted to the hand or arm of the operator via the handle. These vibrations are not only uncomfortable, but can also lead to long-term damage to the health of the operator. Particularly in the performance class of the breakers, the stresses that are reasonable for the operator are mostly exceeded.
  • the invention has for its object to provide a hammer drill or chisel hammer that is lightweight and easy to use.
  • the additional mass In order to achieve a noticeable effect, the additional mass must have a certain minimum size.
  • the additional mass since the total weight of the hammer is directly influenced by the additional mass and the total weight of the hammer is limited for handling reasons, the additional mass must not be too large. In practice it has proven to be expedient if the mass of the housing is 8 to 12 times the additional mass. The preferred proportion of the additional mass in the total weight of the hammer is therefore of the order of magnitude of approximately 10%. In view of the improvement in operating convenience that can be achieved with this, this is entirely acceptable. If larger additional masses are used, the hammers become too heavy and can only be handled with great difficulty.
  • the additional mass is arranged in the axis of the impact transmission to the tool. Since this is usually not possible for structural reasons, only an eccentric arrangement of the additional mass remains on the housing. So that the resulting eccentrically acting forces do not cause the housing to tip, it is advantageous to design the additional mass as a plurality of individually spring-supported mass bodies.
  • the individual mass bodies are preferably arranged symmetrically on the housing. The distributing the additional mass on a plurality of mass bodies results in a further advantage in that the individual mass bodies can be made smaller and, due to the distribution on the housing, act less disruptively than a single, correspondingly larger additional mass. For reasons of cost, two mass bodies are preferably provided.
  • the individual mass bodies In order to achieve the same movement in the case of a plurality of mass bodies, it is therefore expedient for the individual mass bodies to be designed as pistons mounted in guide cylinders and for the ends of the guide cylinders to be mutually connected via pressure compensation lines.
  • the coupling of the individual mass bodies to one another thus takes place via a medium flowing from one cylinder to the other. This can be liquid or gaseous.
  • the natural frequency of the spring-supported additional mass essentially corresponds to the frequency of the striking mechanism.
  • the natural frequency of the additional mass is determined by the size of the additional mass and by the spring constant of the spring supporting it.
  • the additional mass oscillates essentially in phase with the housing. This partly compensates for the shock excitation exerted on the housing.
  • the shock excitation generated by the striking mechanism and acting on the housing can only be partially compensated for by the additional mass.
  • the natural frequency of the handle is smaller by a factor of / 2 than the frequency of the striking mechanism. With this design, the vibrations in the area of the stroke frequency and above are dampened and transferred to the handle.
  • the natural frequency of the handle is also determined by its mass and by the spring constant of the springs supporting the handle.
  • the drill hammer shown in FIG. 1 has a housing designated overall by 1.
  • the housing 1 consists of a motor part la and a striking mechanism part 1b.
  • a spindle 2 protrudes from the striking mechanism part 1b and carries a chuck 3 for a tool 4.
  • a supply line 6 for the. Electrical power supply opens into the handle 5.
  • the handle 5 also carries a switch 7 for switching the hammer drill on and off.
  • the handle 5 can be moved relative to the housing 1 in the direction of impact, ie in the axial direction of the spindle 2.
  • the handle 5 is guided by means of pins 1c and corresponding bores 5a of the handle 5.
  • the handle 5 is pressed away from the housing 1 by compression springs 8.
  • a screw 9 connected to the pin 1c serves as a stop.
  • the gap between the handle 5 and the housing 1, which is larger or smaller depending on the degree of deflection of the handle, is sealed around by a bellows 10 against the ingress of dirt into the interior of the machine.
  • the bellows 10 enables the relative movement between the handle 5 and the housing 1.
  • the absorber housing 11 is connected to the housing 1 and has two guide cylinders 11a running parallel to the axis of impact direction.
  • Mass bodies 12 are arranged in the guide cylinders 11a.
  • the mass bodies 12 are designed as pistons and are guided in the guide cylinders 11a.
  • the mass bodies 12 have an area provided with a spring thread 12a.
  • a spring 13 is screwed onto the spring thread 12a and thus connected to the mass body 12.
  • the other end of the spring 13 is connected to an abutment generally designated 14.
  • the abutment 14 also has a spring thread 14a adapted to the spring 13.
  • the mass body 12 is thus connected to the abutment 14 via the spring 13.
  • the abutment 14 also serves for one-sided closing of the guide cylinder 11a.
  • the other end of the guide cylinder 11a is closed by a plug 15.
  • the mass bodies 12 and the spring 13 form a system which can execute vibrations running parallel to the axis of impact direction. Due to the mass bodies 12 acting as pistons, the guide cylinders 11a are divided into two spaces. One space, in which the spring 13 is also located, is located between the mass body 12 and the abutment 14. The other space is located between the mass body 12 and the plug 15. The spaces in front of and behind the mass bodies 12 are through pressure compensation lines 11b, llc mutually connected. A coupling of the two mass bodies 12 is achieved by this measure.
  • the two mass bodies 12 are dimensioned such that their mass accounts for approximately 10% of the housing with the drive and striking mechanism arranged therein.
  • the natural frequency of the mass body 12 corresponds essentially to the frequency of the Percussion.
  • the suspension of the handle 5 is tuned so that the natural frequency of the handle 5 is about a factor is less than the frequency of the striking mechanism. For example, at a frequency of the striking mechanism of 45 Hz, the natural frequency of the handle is approximately 35 Hz. Such tuning results in an optimal reduction of the vibrations generated by the striking mechanism.
