Definitions

  • the invention relates to a fluid rotation drive, in particular for cleaning devices, with at least one drive wheel, in particular a turbine or paddle wheel, which can be displaced directly by applying a, in particular in jet form, supplied fluid in rotation about a drive axis, and with at least one planetary gear, wherein a sun gear of the planetary gear is connected to the drive wheel.
  • Such drives are known in principle.
  • the disadvantage of such drives is that in practice they have restless running properties.
  • such drives are extremely sensitive to external influences such as load changes in particular.
  • US-A-5 007 127 describes a fluid rotary drive for cleaning devices.
  • the fluid rotation drive has a drive wheel in the form of a turbine or paddle wheel, which can be set into rotation about a drive axis directly by applying a fluid supplied in the form of a jet.
  • the fluid rotary drive has a planetary gear, wherein the sun gear of the planetary gear is connected to the drive wheel.
  • the drive wheel and the planetary gear are contained in a housing having at least one inlet for the supplied to pressurize the drive wheel fluid.
  • a first annular region is defined for the fluid. Due to the toothing of the ring gear of the planetary gear, a second annular region for the fluid is defined.
  • the first ring region and the second ring region are arranged in close spatial proximity to one another.
  • the object of the invention is to provide a fluid rotary drive of the type mentioned, which has a very smooth running behavior with respect to external influences as stable as possible speed.
  • the housing has a closed construction in that the fluid acting upon the drive wheel can not escape in an uncontrolled manner, so that a ring flow is produced which is braked by the toothing of the ring gear.
  • the first annular region and the second annular region can be arranged directly next to each other in the axial direction.
  • first annular region and the second annular region have at least substantially the same radial distance from the drive axis.
  • the planet gears of the planetary gear are arranged on a common carrier, which is displaceable by means of the sun gear in rotation.
  • an axial outlet for the fluid is provided.
  • the ring gear of the planetary gear is formed as a separate, not permanently connected to the housing component.
  • the ring gear can be easily replaced if necessary in an advantageous manner.
  • the planetary gear can be part of a multi-stage transmission. It is particularly provided that the output of the planetary gear connected to the input of another planetary gear is. In this way, in particular a respective desired reduction ratio in a relatively wide range can specify targeted.
  • a planetary gear is arranged on both sides of the drive wheel, wherein the drive wheel is connected to both sun gears of the planetary gear.
  • the invention also relates to a cleaning device with at least one fluid rotation drive of the type specified here for driving at least one working unit, in particular a drive spindle or a cleaning member.
  • the fluid rotation drive directly drive at least one rotating during operation cleaning member.
  • an intermediate member is provided, for example, a drive spindle, via which one or more cleaning members are driven.
  • the cleaning devices need not be rotating cleaning devices during operation.
  • the rotation of the intermediate member, for example a drive spindle, generated by means of the fluid-rotation drive can, for example, also be used to achieve a reciprocating movement of a cleaning member.
  • a cleaning member such as a cleaning brush or roller, arranged on both sides of the fluid rotation drive, wherein the cleaning member is displaceable via a drive shaft in rotation, and wherein the drive shafts of the cleaning members driven by the fluid rotation drive and with a through the fluid rotation drive Through extending support shaft are connected.
  • a particularly stable structure for example, a double or twin roll can be realized.
  • a common support structure is provided for the cleaning members, comprising a longitudinally extending along the drive axis of the fluid rotation drive bearing cage, which contains the fluid rotation drive and is designed as a support for central support rods of the cleaning organs.
  • the housing of the fluid rotary drive may form part of this support cage.
  • each support rod extends into the region of the free axial end of the particular cylindrical cleaning member.
  • Each support bar may be supported by the support cage at least at an intermediate region between the fluid rotation drive and the free axial end of the cleaning member. This axial extension of the support cage in the direction of the free axial ends of the cleaning members advantageously increases the stability of the overall arrangement.
  • an axial fluid outlet of the fluid rotation drive is in fluid communication with a fluid inlet of the cleaning member, in particular with a support rod of the cleaning member.
  • the support bar can be hollow for this purpose be educated.
  • the caring for the rotational drive fluid can therefore also be used as a cleaning fluid and thus doubly.
  • the outline of the Fig. 1 shows a trained as a blade or turbine wheel drive wheel 11 which is rotatable about a drive axis 15.
  • the drive wheel 11 is located in a housing 19 having a fluid inlet 21.
  • a pressurized fluid 13, in particular water, can be directed in jet form through the inlet 21 onto the drive wheel 11 in order to set the drive wheel 11 in rotation about the drive axis 15.
  • a sun gear 17 of a planetary gear On both sides of the drive wheel 11 axially projecting portions each form a sun gear 17 of a planetary gear. In the following, only one output side of the drive wheel 11 will be described.
  • the sun gear 17 cooperates with planet gears 31, which are mounted on a common carrier, not shown here.
  • the cooperating with the planet gears 31 ring gear 25 of the planetary gear is formed as a separate and thus replaceable component.
  • the planet carrier is set in rotation in accordance with a reduction ratio determined by the respective design and is thus available as a drive.
  • the drive train can be followed by another planetary gear.
  • the planet carrier can also directly set a working unit, such as a spindle or a cleaning member in rotation.
  • the drive wheel 11 and the ring gear 25 are matched in diameter to one another such that a first annular portion 27 for the fluid 13, which is defined by the drive wheel 11 and the housing 19, and a second annular portion 29 for the fluid 13, through the Gearing 23 of the ring gear 25 is defined to have substantially the same radial distance from the drive axle 15.
  • the two ring portions 27, 29 are arranged in the axial direction immediately juxtaposed. Due to this spatial proximity of the two Ring areas 27, 29 in an area also enclosed by the housing 19 results in the introductory part explained quiet and stable running and speed behavior of this fluid rotation drive according to the invention.
  • Fig. 1 By the arrow lines is in Fig. 1 purely schematically indicated the way of the fluid 13 through the drive.
  • the fluid 13 entering via the inlet 21 passes between the drive wheel 11 and the planetary gear through to an axial outlet 36, where it is available to be supplied, for example, to a driven cleaning member.
  • the drive wheel 11 may be provided with axial apertures, not shown. In particular, it is possible to form the drive wheel in the manner of a "spoke wheel".
  • illustrated cleaning device comprises a fluid rotation drive 10 according to the invention with a drive wheel 11 and arranged on both sides of the drive wheel 11 planetary gears, which are driven by rotating cleaning brushes 35 during operation.
  • the fluid is supplied via a jet element 45, which can be connected to a fluid source, for example a high-pressure cleaner of conventional type.
  • the fluid passes via an inlet channel 47 to the inlet 21 of the housing 19 (cf., for example Fig. 3 ).
  • the jet member 45 may comprise a high-pressure nozzle unit, which can be used for example by means of a quick connector and easily replaced.
  • Another special feature is the relatively small axial gap between the two cleaning brushes 35, which is provided for the supply of the fluid to the fluid rotation drive and due to its small size in the axial Direction seen a virtually uninterrupted processing of a surface to be cleaned allows.
  • Fig. 3 In particular, it can be seen that on each side of the drive wheel 11, two axially successively connected planetary gear are arranged.
  • the planet carrier 33 of the first planetary gear serves as a sun gear for the second planetary gear.
  • the two axially outer planet carrier 33 each drive a central hollow support rod 43, wherein the support rods 43 serve as drive shafts and are connected to each other via a common, extending through the fluid rotation drive 10 extending central support shaft 39.
  • the housing 19 is part of an axially extending support cage 41 which contains the fluid rotation drive 10 and in which the two hollow support rods 43 are rotatably mounted.
  • an outer jacket 59 of the respective cleaning brush 35 is supported in each case, on the one hand in the vicinity of the free axial end of the support cage 41 and on the other (see, eg Fig. 2 ) at the free axial end of the cleaning brush 35.
  • Fig. 4 In particular, the flow path of the fluid 13 entering the housing 19 via the inlet 21 is illustrated schematically.
  • the fluid rotation drive 10 the fluid passes into the hollow support rods 43, in which outlet openings 49 are formed, through which the fluid passes into the interior of the outer jacket 59 of the cleaning brush.
  • outlet openings 49 can Exiting the fluid from the cleaning brush and wet the surface to be cleaned or the bristles 51 of the cleaning brush.
