Definitions

  • the invention is related to a floor treating machine, comprising a frame provided with a housing which is supported with respect to the frame in such a manner that it can rotate about a substantially vertical housing axis, at least three heads positioned at intervals around said axis and rotatably mounted to the housing, the axis of each head being about parallel to the housing axis, and each head having a bottom surface provided with treating means and/or coupling means for treating means to be coupled to, and a motor on the frame which is in driving interaction with the housing and the heads by means of respective transmissions.
  • Such a prior art floor treating machine is disclosed in European patent application 700327 .
  • Said floor treating machine comprises three heads, which are driven by means of a drive belt.
  • said drive belt is guided around three head pulleys, as well as around a drive pulley which is connected to the motor shaft.
  • the full power of the motor is transmitted through the drive pulley and the drive belt interacting therewith.
  • a relatively wide belt has to be selected.
  • this belt is guided around the head pulleys as well, these head pulleys should be laid out for this width as well. This means that each head is equipped with a head pulley which is larger than necessary.
  • each pulley consumes only a fraction of the total power delivered by the motor.
  • the transmission including drive pulley, head pulleys and the drive belt is a relatively heavy. As explained, this is caused by the fact that the full motor power has to be transmitted through the drive pulley and the drive belt.
  • the object of the invention is to provide a floor treating machine of the type discussed before, which can be of a lighter, and thereby more efficient, construction. Said object he is achieved in that at least two of the heads are drivable by means of separate respective transmissions each comprising a head pulley connected to the respective head, a drive pulley interacting with the motor as well as a belt between each pair of a head pulley and a drive pulley.
  • the transmissions between the motor and the individual heads are not designed for transmitting the full motor power, but for transmitting only the power which is consumed by each of said heads separately.
  • These transmissions can therefore have a belt and pulleys with a smaller width, and can therefore be lighter, as the power to be transmitted through each belt is smaller. Consequently, the complete construction including shafts, bearings and the bearing housings can be smaller and thereby lighter as well, which results in a lighter and therefore more cost efficient construction.
  • a drive shaft can be provided which is concentric with respect to the housing axis, which is rotatably supported with respect to the frame and which interacts with the motor.
  • the drive pulleys are all connected to said drive shaft.
  • the housing can be rotatably supported with respect to the drive shaft.
  • the floor treating machine according to the invention can be carried out in different ways.
  • the position of the motor can be selected freely and also the transmission between the motor and the housing can for instance be carried out with tooth gears.
  • the drive shaft is concentric with respect to the motor shaft.
  • the head transmissions are staggered with respect to each other.
  • the several transmissions which each drive one of the heads are positioned above each other as well.
  • each head can be supported on a head shaft, each head shaft being suspended with respect to the housing by means of an upper bearing and a lower bearing.
  • the transmission between the motor and the housing can be carried out in several ways.
  • said transmission between the motor and the housing comprises at least one auxiliary drive belt.
  • said transmission may comprise a frame pulley connected to the frame, the first auxiliary belt being applied around said frame pulley and a first auxiliary pulley which is rotatably supported with respect to the housing for rotating the housing with respect to the frame.
  • a second auxiliary pulley can be coaxially connected to the first auxiliary pulley, a drive shaft pulley being connected to the drive shaft, and a second auxiliary belt being applied around said second auxiliary pulley and the drive shaft pulley.
  • a well protected embodiment is obtained in case a frame covering is provided, wherein the transmissions are fully contained within the frame covering.
  • the floor treating machine as shown in the figures comprises a housing 11, which by means of the bearings 19 is rotatably supported with respect to the drive shaft 25. Said drive shaft 25 in turn is rotatably supported with respect to the frame 20 by means of the drive shaft bearing 23.
  • the frame 20 carries a motor support 2, carrying the motor 1.
  • the motor shaft 26 of the motor 1 is connected to the drive shaft 25 by means of the coupling 22.
  • the heads 14 each comprises a head shaft 17, which head shafts 17 are rotatably supported with respect to the housing 11 by means of a lower head bearing 16 and an upper head bearing 18. These head shafts 17 each support a head pulley 12; it is to be noted that the several head pulleys 17 are positioned at different levels on the corresponding head shafts 17.
  • each drive pulley 28 is positioned at similarly different levels on the drive shaft 25. Between each pair of a drive pulley 28 and a head pulley 12 which are at the same level, a belt 9 is positioned. Thus, each head 14 and thereby each disc holder positioned at the bottom of each head 14 is driven by its own belt/pulley drive.
  • the transmission between the drive shaft 25 and the housing 11 also contains belt/pulley drives.
  • the drive shaft pulley 28 has been provided.
  • a second auxiliary pulley 10 has been provided, as well as a first auxiliary pulley 29.
  • These auxiliary pulleys 10, 29 are mounted on an intermediate shaft 7, which by means of the bearing 8 is rotatably supported with respect to the housing 11.
  • a frame pulley 21 has been provided, which is fixed with respect to the frame 20.
  • a first auxiliary belt 6 is provided around said frame pulley 21 and the first auxiliary pulley 29.
  • a second auxiliary belt 9 is provided between the drive shaft pulley 28 and the second auxiliary pulley 29.
  • a frame cover 31 is connected to the frame 21, which frame covering 31 covers both the housing 11 as well as the transmission between the frame and the housing.
