Definitions

  • the invention relates to impeller blocks according to the preamble of claim 1.
  • a generic impeller block is manufactured and sold by Mannesmann Demag Fetttechnik AG under the name "RS”.
  • the known impeller block is also known from DE 31 34 750 C2.
  • This known impeller block is formed from two welded together or otherwise connected halves of the bearing housing and has inwardly pressed rotary bearing seating surfaces for bearings in which the hub of the impeller is supported. This close to the hub bearing seating surfaces directed to the hub abutment surfaces for the bearing, and the impeller extends with its hub up over the bearings and is supported directly on the housing, and the hub also has on its two-sided outer rings annular grooves on the front sides of the Bearing snap rings and a receiving opening with an internal toothing for external teeth of a drive shaft.
  • the entire impeller block is again attached to the structure - as in the initial assembly - by means of screws
  • the impeller block must be aligned in its position relative to the structure with the other wheels, so that the axis of rotation of the impeller perpendicular to the impeller, on which rolls the impeller runs.
  • This assembly process is time-consuming due to the complex alignment, which extends the downtime of the entire machine, and therefore also costly. If the alignment process is not performed, there is a risk that the wheels by scraping on the Laufradbahn schrota (rub) and thereby wear out faster. Furthermore, there is the danger in the application of a bridge crane that the running behavior of the bridge crane is sensitive disturbed by skew, tapping and flange wear. In addition, lateral forces occur with increasing skew angle, or the like. burden beyond the operating stress. This problem is described in detail in DIN 15018.
  • EP-A-065 63 13 describes a so-called corner bearing of an impeller with two directly adjacent open sides. This does not correspond to the housing of a wheel block. Moreover, the cover plate is also not, so certainly not in the installed state, of one of the side walls solvable. Once again, the cover plate is no more than a familiar to the expert outer wall of an impeller cover.
  • DE-A-4 235 345 discloses an impeller block, in which the two receiving hubs are formed in each case by projecting into the housing interior parts of two opposing annular body, which can be inserted from the outside into the insertion openings provided in the housing and at which the pivot bearing coaxially are. This makes it possible, after removing the ring body, remove the impeller and the bearings down from the impeller block, without releasing it from the structure.
  • DE-A-4,316,201 impeller block consists of two housing halves, which are detachably connected to each other, but of which not only a single housing half can be solved in the installed state.
  • the impeller block must be completely detached from the structure and replaced to replace wearing parts.
  • DE 4031685 C discloses a Laufradblöck of two housing schools of injection molding, which are draff and / or positively connected with each other.
  • the present invention has for its object to minimize manufacturing and assembly costs by an advanced design of a wheel block and to increase the utility of the impeller block thereby, that the disadvantages of known impeller blocks are avoided.
  • the stated object is achieved according to the invention in a first variant with the features of claim 1.
  • the present invention enables the Replacing the impeller and / or the bearing, without the housing must be solved by the structure. This eliminates the time- and cost-intensive alignment process following the replacement of wearing parts, the housing is reusable and remains aligned on the structure or the like., As long as desired.
  • the Kopfarischluß Structure and / or a cheek surface and / or a face connection surface is divided into overlying and non-resting partial surfaces.
  • a resting partial surface is undivided, i. has no parting line.
  • the flatness of the surface is correspondingly more accurate with a homogeneous material and smaller partial surfaces as connecting surfaces than with several or large partial surfaces.
  • defined forces are introduced into the connecting structure via the smaller partial surfaces. This allows an optimized design of the connecting structure with known power flow.
  • This variant of the invention allows the replacement of the impeller and / or the bearing, without the housing must be detached from the structure. This eliminates the time- and cost-intensive alignment process following the replacement of wearing parts, the housing is reusable and remains aligned on the structure or the like., As long as this is desired.
  • the housing is reusable and remains aligned on the structure or the like., As long as this is desired.
  • the connection means to use also insoluble, because the block-shaped housing of the relevant structure, support or chassis no longer needs to be solved.
  • Further advantages result from the fact that both the cover and the spacers can be manufactured as inexpensive mass-produced, so that the unit costs can be significantly reduced at correspondingly high quantities.
  • a further advantage is that the newly developed impeller block can be completely disassembled and recycled into its components. This is particularly advantageous with regard to increasing disposal costs and the disposal of materials separate disposal.
  • two separate spacers are arranged in front of and behind the impeller seen in the direction of travel. These are relatively light pieces with plane-parallel side surfaces, which can be made correspondingly advantageous.
  • the housing is made einstükkig and down and to a cheek side open.
  • An impeller block ( Figures 1 A and 2A) has a housing 101 in which pivot bearing seating surfaces 102 (see Figure 6A) for sliding and / or rolling bearings 103 are provided for receiving an impeller 104 which projects generally downwardly.
  • the housing 101 can be dismantled and reconnected into housing parts at least on one side, a support or travel frame 105 (see FIGS. 8A to 10A) determining the construction direction.
  • the impeller block is attached to such a support or traveling frame 105 as will be described later.
  • the housing 101 is block-shaped, i. viewed from the side and from top or bottom either square or rectangular or trapezoidal.

Like.) - See. Fig. 8A - between the housing 101 and the carrier to be connected to the wheel block support, traveling frame 105 or the like. are arranged.
  • the head connection surface 108 and / or a cheek surface 110 and / or an end connection surface 111 are subdivided into resting and non-resting partial surfaces 112 and 113 (compare FIGS. 2A and 7A).
  • the resting partial surfaces 112 take over the respective carrying capacity or partial load. In this case, an overlying partial surface 112 is itself undivided, although a plurality of such resting partial surfaces 112 may be present.
  • This system of the resting partial surfaces 112 and the non-resting partial surfaces 113 makes the position of the entire wheel block statically determined after its adjustment to the support or traveling frame 105, safely and clearly.
  • This occupied position can therefore be maintained before, during and during the replacement of the sliding and / or roller bearings practically for life.
  • the advantage here is that an overlying part surface 112 is undivided, ie has no parting line
  • the flatness of the surface is correspondingly more accurate in a homogeneous material and smaller sub-areas as pads accordingly than with multiple or large sub-areas.

  • a lateral expansion of the bearing and / or the impeller is possible.
  • the lateral expansion reduces the disassembly and assembly costs of the impeller in that now the supporting structure, the carrier or the running frame only has to be raised by the flange height of the impeller.
