Definitions

  • the invention is based on a hand machine tool the preamble of claim 1. It is already a hand machine tool known (DE-A-42 31 985), in which a fan wheel for cooling the drive motor in a rotationally fixed manner on the motor shaft is arranged. The speed of the fan wheel corresponds to this the engine speed. To achieve sufficient funding the fan wheel must pass through the fan accordingly be designed large, which requires a large amount of space.
  • the hand tool according to the invention with the features of claim 1 has the advantage that the fan in comparison can be operated to drive different speeds is.
  • the fan can be compared with one operate the engine speed at higher speed, whereby with the same size, a higher suction or blowing power or a smaller design with the same suction or blowing power is made possible.
  • a higher fan speed is, for example then advantageous if in the event of an overload at low Engine speed requires a high cooling capacity is.
  • FIG. 1 shows a partial section of a rotary hammer as an example of a hand tool according to the invention
  • FIG. 2 shows the drive part of FIG Hand tool according to Figure 1.
  • 10 denotes a hammer drill, which as Example of a hand tool according to the invention serves.
  • the hammer drill 10 has a housing 11 in which a drive motor 12 is housed. By the drive motor 12 a motor shaft 13 can be driven in rotation. On your tool side The end is the motor shaft 13 with a pinion 15 provided that in engagement with a not shown Gearbox stands, the drive torque on a Not shown drilling spindle and / or on a likewise transmits percussion not shown.
  • the Motor shaft 13 is via a roller bearing 16 opposite the housing 11 of the rotary hammer 10 rotatably mounted.
  • a fan 18 is provided for cooling the drive motor 12, which has a fan wheel 19.
  • the fan wheel 19 is on the motor shaft 13 between the drive motor 12 and the roller bearing 16 arranged and opposite this by means of a bearing 20 rotatably mounted.
  • Motor shaft 13 and fan wheel 19 are standing via a transmission shown only in principle in FIG. 1 21 in operative connection.
  • FIG 2 the drive part of the hammer drill 10 is closer shown.
  • the drive motor 12 faces the motor shaft 13 facing away from a collector 24.
  • Tool side the roller bearing 16 can be seen, via which the motor shaft 13 is rotatably supported relative to the housing 11.
  • the fan wheel is between the drive motor 12 and the roller bearing 16 19 arranged and via the bearing 20 on the motor shaft 13 rotatably mounted.
  • the transmission 21 is in the example as Belt drive trained.
  • a first round cord 21a connects the shaft 13 with an idler gear 25, which is on a housing-fixed pin 26 rotatable via a needle bearing 27 is stored.
  • a second cord 21b connects this Intermediate wheel 25 with a non-rotatably connected to the fan wheel 19 Drive wheel 28.
  • the gear 21 Speed of the fan wheel 19 compared to the speed of the motor shaft 13 increased. In this way, the suction or Blowing performance of the fan 18 compared to conventionally arranged Increase fans.
  • the transmission 21 can also be used as a gear transmission, for example, designed as a planetary gear be. Of course, other embodiments are also possible from translation gears.
  • the blower 18 can also be used as a suction fan for removed material, for example Drilling dust can be used.
  • the invention is basically with all hand machine tools, such as drills, Grinder, saws etc. applicable.
