Definitions

  • Each brand of sweeping machine has a different shaft geometry and dimension, and this means that spare part supplies must, until now, be supplied by said brand.
  • a coupling device for coupling a shaft of a street sweeping machine to a roller brush
  • the roller brush is normally formed by a set of modules provided with securing means for securing the bristles and spacing means for spacing between each two of said modules, and wherein the interior contour of the body of the brush has a substantially cylindrical geometry, provided with a set of indentations and also provided with a set of tabs or projections.
  • the set of indentations is intended for shafts with non-circular geometries, e.g. square, the greatest dimension of which is greater than the diameter of the hollow of the brush, so that the angular edges of the non-cylindrical shaft, e.g. square, triangular, pentagonal, etc., are inserted in said notches.
  • the set of tabs or projections is intended for shafts with a cross section smaller than the interior cross section of the body of the brush, by using an adapting piece for adapting between brush and shaft.
  • This adapting piece has extensions that match the tabs or projections provided in the interior hollow of the brush.
  • the adapting piece can have different geometries, e.g. square, round with a key way or triangular.
  • the adapting piece may be modular, such as the brush forming elements, or it may be of such a length that it links two or more modules to the shaft, or all of the modules.
  • the aim is to provide a versatile coupling that can be adapted to different geometries of a shaft of a street sweeping machine to a roller brush, which allows a standardisation of the required spare parts due to the intense wear to which this type of machine is subjected.
  • an element of a body of the brush Whether the body is a bristle support, a spacing element or a combined element which fall outside the object of the present invention is irrelevant.
  • This element has an interior hollow 2 with a substantially circular shape.
  • Said element (1) of the body of the brush has a set of notches (3) arranged in a regular or irregular manner along the interior perimeter of the cross section.
  • the angular portions of a shaft with a cross section greater than that of the nominal diameter of the interior hollow (2), only exceeded by said notches (3) can be inserted into said notches (3).
  • a shaft with a square section (6), the diagonals of which are greater than the nominal diameter of the interior hollow (2) is coupled to said notches (3).
  • the force exerted by the shaft (6) will produce a tangential stress in the area of the notches (3) which will cause the element (1) to rotate.
  • the angles of the notches (3) shall be those suitable for the different shaft geometries.
  • the element (1) is also provided internally with a set of projections or tabs (4), grouped in pairs, which form respective housings (5).
  • housings are designed to allow the fitting of respective protuberances (9) arranged externally on adapting pieces (8,11) to shafts (7,10) with geometries with a cross section smaller than that of the interior hollow (2) of the brush.
  • the coupling comprises an adapting piece (8) for adapting a shaft with a square cross section (7), with diagonals smaller than the interior diameter of the brush, wherein said shaft is inserted into the interior hollow of said adapting piece (8), and wherein said adapting piece is in turn provided with protuberances (9) which are coupled to the housings (5) in the body of the brush, formed by projections or tabs (4).
  • the coupling comprises an adapting piece (11) for adapting to a shaft with a round cross section (10) with a key way, wherein the shaft has a diameter smaller than the interior diameter of the body of the brush.
  • the shaft is inserted into the interior hollow of the adapting piece (11), which in this case is in turn provided with interior projections (12) as a key way.
  • Said adapting piece (11) is also provided with protuberances (9) that are coupled to the housings (5) in the body of the brush, formed by projections or tabs (4).
