Definitions

  • the invention relates to a brush roller of the type specified in the preamble of claim 1, which is intended for sweepers, in particular street sweepers.
  • Brush rollers of this type are known (GB-A-814113) which have a cylindrical support tube and a plurality of profile strips which extend axially over the support tube jacket, are spaced apart from one another in the circumferential direction and are provided with tufts of bristles arranged one behind the other.
  • the outer surfaces of the profile strips form an angle diverging towards the foot end to form wedge surfaces, so that the profile strips. can be clamped by wedges to produce a rigid ring connection on the lateral surface of the support tube, the wedges abutting against the facing wedge surfaces of adjacent profile strips and can be fixed on the support tube by means of screws engaging in threaded bores of the support tube.
  • the tufts of bristles are used there in steel sleeves, which are individually welded to the profile strips at a distance from one another. A large number of spot welds are therefore required for the production of the brush roller. This means time-consuming manual work. It is also considered disadvantageous that the centrifugal forces acting on the bristle tufts must be absorbed by the weld seams holding the steel sleeves. Since the strength of the weld seams is limited, there is therefore a risk that individual bushes will become detached from the rapidly rotating brush rollers and damage nearby objects and injure people. In addition, the exchange of the worn bristle tufts is relatively cumbersome and time consuming.
  • Brush rollers are also known (DE-A-3 023 745) which have a rotatably mounted central support tube which is provided with a number of welded-on ring flanges.
  • the ring flanges are provided at their edges with open-edge recesses, in which axial holding elements are welded, which have opposing open slots for receiving bristle bars provided with tufts of bristles.
  • the brush rollers When used as intended, the brush rollers are exposed to considerable forces and vibration. These are transferred to the welded joints so that there is a risk of fatigue cracks. Repairing or replacing the welded parts is quite difficult and time-consuming. Apart from that, the welded connections already require a considerable amount of time in the manufacture of the brush rollers.
  • the invention has for its object to provide a brush roller that can be made as possible without welded connections and the wear parts can be easily replaced for maintenance and repair purposes.
  • the radially outward-facing sides of the bristle rails and the profile strips with their holding rails thus form a closed outer surface, which prevents dirt, snow or water from getting into the space between the bristle rails and the support tube, as is the case with the known brush rollers.
  • the precautions according to the invention thus prevent dirt or ice from accumulating in the spaces mentioned, which can lead to an undesirable unbalance when the brush roller is rotated.
  • the central tube and the profile strips can be manufactured with sufficient dimensional accuracy so that the profile strips can be placed and aligned with good accuracy on the support tube using the wedges.
  • the profiled strips equipped with the holding rails are aligned without a welded connection on the supporting tube in such a way that the axial recesses in pairs in the holding rails, which form opposite one another, form a form-fitting seat with good dimensional accuracy for the respective bristle rails.
  • the profile strips extend over the entire length of the support tube and thus form a stable holding device for the bristle rails over their entire length in the clamped state.
  • the bristle rails are therefore not subject to any bending stress and can therefore be produced with a significantly smaller wall thickness than was the case with the known brush rollers. Since the holding rails are made of plastic, a certain play of the bristle rails in the recesses of the holding rails is permitted without the risk of wear.
  • the bristle rails Since neither the holding rails nor the bristle rails have selective supports, but are supported over their entire length over the entire length of the profile rails, the bristle rails are not bent during use, so that they always remain straight and, if necessary, are pulled out of the region of the holding rails and pushed back into them can be.
  • the brush roller contains a central support tube 10 which can be rotatably supported in a known manner.
  • a number of profile strips 11 made of light metal are arranged in the axial direction, each having the same distances from one another in the circumferential direction.
  • the length of the profile strips 11 corresponds essentially to the length of the support tube 10.
  • profile strips 11 are made of light metal, they can be produced simply and inexpensively using the profile shown in FIG. 3.
  • the profile strips 11, which are mirror-symmetrical to their vertical center plane, have two legs 12, 13 in the region of their foot end, which bear against the support tube.
  • the two opposite outer surfaces 14, 15 enclose an angle diverging towards the foot end, so that they form wedge surfaces towards the outside.
  • the outer part of the profile strips opposite the foot end is provided on both sides with grooves 16, 17 which are cup-shaped in cross section.
  • holding rails 18, 19 made of plastic are embedded, which in turn have axially extending recesses 20, 21 on their outside for receiving a side edge 22, 23 of a bristle rail 25 with a rectangular cross-section.
  • the bristle rails are equipped with a larger number of bristle tufts 26 arranged one behind the other.
  • the profile strips 11 are releasably clamped to the support tube 10 with a number of wedges 27.
  • the wedges are tightened with the aid of screws 28 which engage between threaded sections 29 in threaded bores 29 of the support tube 10.
  • the profile strips clamped in this way with the help of the wedges against the support tube and against one another form a rigid and stable ring around the tube, as can be seen from FIG.
