Definitions

  • the present invention relates to a floor grinding machine according to the preamble of patent claim 1.
  • the present invention now has the object of improving a ground grinder of the type mentioned above, that the advantages of the known floor grinding machines are maintained, but the device is better to use, the mechanical drive parts are protected against contamination and repair and maintenance work easily and without Danger of accidents for the personnel can be carried out.
  • a floor grinder ( Fig. 4 ) as presented on the basis of the invention, always consists of a frame 20 which is equipped with a drawbar 21, with wheels 22 and rollers 23.
  • the rollers 23 serve only to transport the floor grinding machine and can be folded up for the grinding process by means of a hydraulic device on the drawbar, while the wheels 22 are used by the person who operates the floor grinding machine during the grinding process as guidance and weight support.
  • the important parts for the work process are drive 1, housing box 11 and grinding tools 30. These parts are held by the frame 20.
  • the drive 1 is fixed to the frame 20.
  • the housing box 11 is rotatably supported in the frame 20.
  • the tool axes 31 of the grinding tools 30 are arranged eccentrically but at the same radius. All tool axes 31 are rotatably mounted in the housing box 11.
  • the drive of the unit is ensured by the fixed to the frame 20 drive 1 ( Fig. 1 and Fig. 2 ).
  • the drive 1 may be an electric motor, a gasoline engine, a diesel engine or a power unit driven by other energy.
  • the central shaft 12 With the central shaft 12, the extension of the drive shaft of the drive 1, a main drive wheel 2 is firmly connected.
  • the main drive wheel 2 drives a unilaterally grooved drive belt 3.
  • the elevations of the longitudinal grooves on the circumference of the main drive wheel 2 engage in the recesses of the drive belt 3 so that the drive belt 3 as long as it is kept under a certain voltage, can not slip laterally from the main drive wheel 2.
  • the drive belt 3 drives the Gereteantriebsrad 7.
  • the voltage is held by the so-called belt tensioner 6, which in turn has the same creasing.
  • Main drive wheel 2, Gereteantriebsrad 7 and belt tensioner 6 so ensure that the unilaterally longitudinally grooved drive belt 3 does not slip laterally, although the force acting on it could cause this.
  • the longitudinal grooves of the drive belt 3 thus engage in the longitudinal grooves of the main drive wheel 2, the Gereteantechnischsrades 7 and the belt tensioner. 6
  • the drive belt 3 drives the tool drive wheels 4, which are fixedly connected to the tool shafts 31.
  • the wrap angle of the tool drive wheels 4 is extremely large by this construction, which ensures optimum power transmission. Nevertheless, given the choice of a unilaterally grooved drive belt 3 whose other side is flat but also given the opportunity to give the grinding tool 30 at very high resistance a certain amount of slippage. This function acts like a slipping clutch that only works in an emergency, but does not cause any damage when slipping.
  • Both the tool shafts 31 of the grinding tools 30 and the axes of the transmission 5 are rotatably supported in the housing box 11 and mounted ( Fig 1 ). They rotate with the housing box 11 about the central shaft 12.
  • the housing of the transmission 5 is supported by a torque arm 13, which is supported on the housing box 11 ( Fig. 1 ) held against turning.
  • a so-called CYCLO transmission is used.
  • the Gereteabretesrad 8 and the toothed belt 10 are connected by a toothed belt 9.
  • the toothed belt wheel 10 is fixedly connected to the frame 20 of the floor grinding machine.
  • the rotation of the Gereteabretesrades 8 therefore causes the supported by means of torque arm 13 on the housing box 11 gear 5 rotates about the timing pulley 10 and thus about the axis of the central shaft 12. Because the gear 5 is held in the housing box 11, this is set in rotation.
  • the axes of the tool shafts 31, which are also held in the housing box are taken.
  • the magnitude of this rotation is determined by the built-in gear 5 translation.
  • the gear 5 moves with the rotational movement of the housing box 11, so that its weight causes a rotating displacement of the gear 5 eccentric lying center of gravity.
  • the whole drive unit is effectively protected by the housing box 11 against dirt and other external influences.
  • the unit is very compact in this way and the bottom grinding machine becomes much easier to handle thanks to this constructive solution.
  • main drive gear 2 gear drive gear 7, tool drive gear 4, gear output gear 8 and toothed belt wheel, as well as the translation of the cyclo-transmission 5 must be designed accordingly.
