Definitions

  • the invention relates to impeller blocks according to the preambles of claims 1, 4, 6, 9 and 12.
  • a generic impeller block is made by Mannesmann Demag bettingtechnik AG manufactured and sold under the name "RS". Of the Known wheel block is also known from DE 31 34 750 C2.
  • This known impeller block is made of two welded together or otherwise connected halves of the bearing housing formed and pressed inward Pivot bearing seats for bearings in which the hub of the impeller is supported.
  • the rotating bearing seat surfaces are directed towards the hub Contact surfaces for the bearings, and the impeller with its hub extends beyond Bearing and is supported directly on the housing, and the hub also points on their outer rings on both sides, ring grooves for on the end faces of the bearings adjacent snap rings and an opening with internal teeth for an external toothing of a drive shaft.
  • a disadvantage of the known impeller block is that to replace the impeller Impeller block in its entirety from the frame, chassis, Structure or the like must be completely solved.
  • the entire impeller block is attached to the The structure - just like the initial assembly - is fastened with screws.
  • the impeller block but in its position relative to the structure with the others Impellers are aligned so that the axis of rotation of the impeller is perpendicular to The runway on which the wheel rolls is running.
  • This assembly process is through the complex alignment is time-consuming, which reduces the downtime of the Entire machine extended, and therefore also cost-intensive. If the Alignment process is not carried out, there is a risk that the impellers through Grind (rub) the skew on the running track and therefore faster wear out.
  • FR-A-2667543 describes an impeller block with a housing which consists of two housing halves which together form the connection surface on one housing side.
  • This impeller block must be completely detached from the supporting structure and dismantled in order to replace wearing parts. This has the disadvantage that a new alignment and adjustment is required after reattaching the impeller block.
  • EP-A-04 06 922 discloses a wheel block in which a peripheral wall part realizes the distance between the side walls. However, in this wheel block version, none of the side walls can be removed in the installed state.
  • this Umpfangswandteil is a completely normal housing wall that is fixed, ie not detachably, connected to the side walls.
  • EP-A-065 63 13 describes a so-called corner bearing of an impeller two immediately adjacent open pages. This is not the case Housing of an impeller block. Furthermore, the cover plate is not, either especially not when installed, detachable from one of the side walls. Here too again the cover plate is no more than an outer wall familiar to the expert an impeller cover.
  • DE-A-4 235 345 shows an impeller block in which the two Receiving hubs each through parts protruding into the interior of the housing Opposing ring bodies are formed, which from the outside in the corresponding in the housing provided insertion openings and where the rotary bearing coaxial are set. This allows the impeller and after removing the ring body take the bearings down out of the wheel block without removing it from the Structure to solve.

This eliminates the time-consuming and costly alignment process after replacing Wear parts, the housing is reusable and remains aligned with the Structure or the like, as long as this is desired.
  • the head connection surface and / or a Cheek surface and / or an end connection surface in lying and not lying Subareas is divided. This makes the introduction of force more defined than before, and it is significantly in the machining performance or the production of the impeller block Machining volume saved.
  • the object is achieved in a second variant in that the Housing consisting of covers arranged on both sides and at least one, both covers a circumferential section connecting spacers with a load capacity receiving, extending to the housing width or the impeller width Head connection surface is formed, on the connecting means to a support structure, support, Moving frame or the like are provided, and that the lid on or in lid hubs Bear pivot bearings on both sides, which are about the width of the impeller or one Lock the impeller hub.
  • This variant of the invention enables the exchange of the impeller and / or the Bearing without having to detach the housing from the structure. This eliminates the time-consuming and costly alignment process after replacing Wear parts, the housing is reusable and remains aligned on Structure or the like, as long as this is desired. There is also the advantage, besides releasable fasteners to use because the block-shaped Housing no longer detached from the relevant structure, carrier or moving frame must become. Further advantages result from the fact that both the cover and the spacers can be manufactured as inexpensive mass-produced goods, so that at correspondingly high quantities, the unit costs can be significantly reduced can. Another advantage is that the newly developed wheel block completely in its components can be dismantled and recycled. This is particularly true in With regard to increasing disposal costs and the separate according to materials Disposal advantageous.
  • the object is achieved in a third variant in that the housing has at least one head connection surface, cheek or face connection surface, which takes up the load-bearing capacity and extends approximately to the housing width or impeller width, and is designed on a cheek side in the direction of the shaft axis without a supporting housing part is.
  • An impeller block assembled in this way remains aligned even when the slide and roller bearing and / or the impeller are removed, because both the slide and roller bearings and the impeller can be pulled off to one side, to which there is sufficient space for the removal movement.
  • This variant of the invention therefore enables the impeller and / or the bearing to be replaced without the housing having to be detached from the supporting structure. This eliminates the time-consuming and costly alignment process following the replacement of wear parts, the housing can still be used and remains aligned with the structure or the like, as long as this is desired.
