Definitions

  • the invention relates to a floor polishing machine in general and more particularly to a scrubbing-polishing machine having an improved driving system.
  • Conventional floor-polishers include an electric motor driving through belts or by friction engagement a plurality of rotating bodies in form of disks that carry the brushes.
  • Such rotating bodies are usually placed around the central axis of the machine and are coupled to the motor by belts or by friction engagement of the lateral surface of the rotating bodies.
  • polishing machines have a number of inconveniences, mainly due to the slipping of the driving.shaft over either the peripheral rubber driving members or belts, and to the power loss caused by worn out friction members or belts. Furthermore the rotation of close brushes only rotating about their axis, produces a polishing with close parallel strips corresponding-to the movement of translation of the machine when in use. The aesthetical result of the polishing is therefore partially spoiled by the excessive evidence of polishing streaks that are rather narrow.
  • the polishing machine of the invention having the drive system schematically illustrated in Figs. 1 and 2 includes a main gear wheel or pinion 1, connected to the electric motor through means not shown in the figures, engaging a first drive member or gear wheel 2 having a diameter that is much 'larger than the diameter of pinion 1.
  • a second drive member or gear wheel 3 having a diameter approximatively equal to the radius of gear wheel 2 and fixed to the frame of the machine.
  • gear wheel 3 is stationary with respect to the machine i.e. it docs not rotate and engages other gear wheels 4 rotatably mounted on gear wheel 2 thanks to shafts 5 passing therethrough and suitably supported as to rotate with respect to gear wheel 2.
  • shafts 5 carry brushes 6 of the polishing machine, either directly by-means of hubs or by means of suitable support bodies in form of disks of a type usually employed in the art. More particularly there can be used brushes not requiring a support body as the onesdisclosed in the Italian Patent Application No.25600 A/80 filed on October 27, 1980 in the name of the applicant. Such brushes are particularly suitable to realize a polisher with reduced height when employed together with the epicycloidal drive of the present invention.
  • a further brush 10 for polishing the floor corners can be provided at the periphery of wheel 2 and will be illustrated in more detail later.
  • Main shaft or pinion 1 is forced to rotate by the electric motor and keeps rotating the first drive member or gear wheel 2 carrying the brushes. Thanks to the above mentioned arrangement brushes 6 are driven along a revolution path around central axis 9 of the machine. Moreover the coupling between stationary gear wheel 3 and gears4 causes brushes 6 to further rotate about their axes 8 when rolling over stationary gear 3. Therefore the motion of each brush is of a sun-and-planet type, i.e. similar to the combined rotation of a planet on its axis and revolution about a central axis.
  • the drive or transmission system is simpler, less cumbersome and requires less servicing when compared with the belt or friction transmission systems of today.
  • a maximum of polishing efficiency can be obtained by a low power motor and the speed ratios are chosen in order to give the best polishing effect.
  • the angular velocity of gear wheel 2 is about 180 rpm whereas the satellite gears 4 rotate about their axes at about 400 rpm.
  • the velocity of a brush element at a given instant will be the vectorial sum of the component due to the revolution about axis 9 and of the component due to the angular velocity of the brush element about axis 8.
  • the transational movement imparted by the user moving the polisher over the floor is to be added to the above motion.
  • Transmission or drive means have been shown as gear wheels but it will be evident to the skilled of the art that different transmission means, such as friction wheels, can be used.
  • additional brushes or brush sectors 20, not rotating and having a shape generally triangular or trapezoidal, are positioned near the periphery of gear wheel 2 to enhance the polishing action of the rotating brushes. Since these non rotating brushes 20 are fixed to gear wheel 2, they only accomplish a revolution motion about central axis 9 of the machine. The effect of such brushes, in addition to increase the number of passagesover a given surface so that the machine appears as having a single large brush (61 in Fig. 6), is to render the polished surface uniform. Referring to Figs. 4 to 6 the polishing result of a conventional polisher having three or four rotating brushes is compared to the one of a polishing machine according to the present invention. Fig.
  • the polish obtained with the machine according to the invention is such as to produce a single uniformely polished area having a width equal to the width of gear wheel 2, i.e. to the entire machine (62 in Fig. 6).
  • Advancing the machine produces a polished band 50, practically omogeneous and quite large so that the floor appears as polished in a more uniform way.
  • polishing is obtained by the combined action of the rotation and revolution motions of brushes 6 and 20.
  • one or more additional outer brushes can be mounted, one being shown with reference 10 in Figs. 1 to 3.
  • Such brush is mounted on shaft 11 outside gear wheel 2 and is driven by a gear wheel 12 directly engaging the outer periphery of gear wheel 2.
  • the usefulness of such additional brush is rather evident for polishing floor corners.
  • a small peripheral outer brush rotating at high speed and adapted to polish perfectly also the floor corners where the machine could never reach can be obtained.
  • Italian Patent Application No.25602 A/80 filed on October 27, 1980 in the name of the applicant.
  • a plurality of rotating outer brushes can be arranged around the machine, but a single brush for polishing the corners is preferable and usually sufficient to the purpose.
  • This-outer brush too can be equipped with a drive means without gear wheals but, for example, can provide for a friction means.
  • the epicycloidal drive system of the present invention is quite adapted for building a polisher having a very low main body and to which a drive bar is applied that is foldable over the body in rest position as disclosed in the Italian Patent Application No.25603 A/80 filed on October 27, 1980 in the name of the applicant.
