Definitions

  • the present invention relates to a floor-treating machine, more particular a floor grinding, polishing or surfacing machine.
  • Conventional floor-treating machines usually comprise a frame, a housing attached to the frame, one or more heads holding an abrasive disk mounted in the housing and rotatable about a substantially vertical axis, and a motor for driving the heads.
  • a general disadvantage of such conventional floor-treating machine is that it is difficult to operate due to its relatively unstable behavior.
  • floor-treating machine were developed of which the housing is rotatable about a substantially vertical axis such that the housing rotates in one direction and the heads rotate in the reverse direction (so-called contra-rotation) via respective transmissions.
  • W00187540 proposes a floor-treating machine wherein the motor is centrally positioned and wherein the housing is driven by an auxiliary shaft which is positioned in parallel to and at a distance from the center axis of the frame and which is connected via a first auxiliary belt transmission to the motor shaft and via a second auxiliary belt transmission to the housing.
  • auxiliary belt transmissions for driving the housing are mounted outside the housing.
  • a first drawback of the floor-treating machine as described in the above patent application is that, because the first auxiliary transmission is connected to the motor shaft, assembling and maintaining this machine is difficult and time consuming.
  • a person skilled in the art will recognize that, on the one hand, in order to install the transmission belt connecting the auxiliary shaft and the motor shaft, obviously the motor has to be mounted. On the other hand, if the motor is already mounted, obviously the transmission belt cannot be installed around the motor shaft. Consequently, the only way proper way to decently install motor and transmission belt is mounting them simultaneously, which is obviously quit difficult and time consuming. So, if during maintenance the auxiliary transmission belts have to be changed, always motor and first auxiliary transmission belt have to dismounted and mounted simultaneously.
  • the present invention meets the above objects by providing a floor-treating machine wherein the auxiliary shaft for driving the housing is connected via a first auxiliary transmission to the housing shaft.
  • the present invention is directed to a floor-treating machine, comprising: a frame (70), a housing (62) attached to the frame (70) and rotatable about a substantially vertical axis, one or more heads (64) mounted in the housing (62) and rotatable about a substantially vertical axis, a motor (50) with a motor shaft (51) for driving a housing shaft (54), said housing shaft (54) connected to the one ore more heads (64) by means of a transmission, an auxiliary shaft (57) for driving the housing (62), characterized in that the auxiliary shaft (57) is connected via a first auxiliary transmission (52, 53, 55, 56) to the housing shaft (54) and via a second auxiliary transmission (58, 59, 60) to the housing (62).
  • the present invention provides a floor-treating machine, comprising:
  • the auxiliary shaft is connected via a first auxiliary transmission to the housing shaft and not to the motor shaft, the first auxiliary transmission does not have to be connected simultaneously with the motor. In case parts of the auxiliary transmission have to be repaired or replaced, it is only required to dismount the motor. Obviously assembling and maintaining the machine becomes less difficult and less time consuming.
  • Another advantage is that it is possible now to completely pre-assemble the frame including housing resulting in easier transportation, transportation cost saving, and ease of installation of the motor to make the machine ready for use.
  • the motor may be positioned concentrically with respect to the vertical axis of the frame (70). In combination with the rotation of the housing and the contra-rotation of the heads, this may result in even more stable behavior of the floor-treating machine.
  • the auxiliary shaft may be positioned parallel to and at a distance from the centre axis of the frame (70).
  • the auxiliary transmissions may be any kind of transmission adapted for connecting the auxiliary shaft to the housing shaft and to the housing, such as a pulley and belt transmission, or a gear wheel and chain transmission.
  • the auxiliary transmission (52, 53, 55, 56) may be situated outside the housing (62), making the transmission easily accessible.
  • the housing shaft (54) may bear a driving pulley or gear wheel (53) fixed to the housing shaft directly or, in case the length of the housing shaft is not sufficient, mounted on a bus (52) fixed to the housing shaft.
  • the driven pulley or gear wheel (56) may be connected via a belt or a chain (55) to the driving pulley or gear wheel.
  • the driven pulley or gear wheel (56) may be fixed to the auxiliary shaft (57) which is rotatably attached to the frame (70) and which drives the housing.
  • the auxiliary shaft (56) may drive the housing be means of a pulley and belt transmission, or a gear wheel and chain transmission (58, 59, 60).
  • the driven pulley or gear wheel (56) may be connected to the housing via a speed reduction mechanism, resulting in easier leveling of the speed reduction between housing shaft rotation and housing rotation.
  • the shaft of the motor may be connected via a plug or claw coupling to a journal on the housing for driving the heads, and the belt transmission for driving the housing coincides with the shaft of the motor.
  • the floor-treating machine in accordance with the present and as illustrated in FIG 1 has a frame 70, to which an actuating lever is attached.
  • the device can be advanced and steered over a surface to be treated by means of this lever.
  • the frame 70 also bears a motor 50 which is connected to a drive roll via a motor shaft 51 and housing shaft (54).
  • the housing 62 is mounted rotatably on the frame by means of bearing 69.
  • This housing accommodates three rolls 66 which each bear a head 64, and the drive roll.
  • An abrasive disk can be coupled to each head 64 by means of coupling means (not shown).
  • the rolls 66 are mounted in the housing 62 by means of bearings 68, 63.
  • the belt 65 can be held at the desired tension by means of the tensioning rollers 11, 12.
  • the housing 62 also bears a pulley 60 which is connected to the pulley 58 via the belt 59. This pulley 58 is attached to the auxiliary shaft 57.
  • the housing shaft 54 bears a driving pulley 53 which is connected via a belt 55 to the driven pulley 56.
  • the driven pulley 56 is fixed to the auxiliary shaft 57 which is rotatably attached to the frame 70 and which drives the housing via pulley 58, belt 59 and pulley 60.
  • the driving pulley 53 is mounted on bus 52 fixed to the housing shaft 54.
  • Dust, waste, etc. which is produced during the abrasive movement can be collected by means of an apron connected to the frame 70.
