Definitions

  • the invention relates to an impeller block having a housing with at least one supporting surface receiving the bearing surface and with pivot bearing seating surfaces for sliding and / or rolling bearings for the storage of an impeller, wherein for disassembly of the impeller from the housing, the sliding and / or rolling outwards and the impeller are expandable to an approximately transverse side towards it.
  • impeller blocks are formed from two welded together or otherwise connected halves of the bearing housing and have pressed-Drehlagersitz lake for bearing in which the hub of the impeller is supported. This is followed by the hub bearing seating surfaces directed to the hub stop shoulders 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 for at the ends of the camp adjacent snap rings and a receiving opening with an internal toothing for external toothing of a drive shaft.
  • the impeller block has a housing, are provided in the pivot bearing seats for sliding and / or rolling bearing for receiving a projecting at least one side impeller, the housing for removing the impeller to one side by taking a detachable lid can be dismantled is, so that the housing for impeller replacement must not be solved by the structure.
  • this impeller for mounting or dismounting a variety of parts must be solved or fixed.
  • wheel block Another construction of a wheel block is from the DE 195 40 217 C1 known. It provides for the use of so-called ring bodies, which serve to accommodate the bearings in the housing walls of the impeller block. They are pushed to insert the impeller with its hub from the outside to the hub and its bearings and fixed in the housing. Also in these wheels, the assembly or disassembly is associated with the loosening or securing a plurality of parts. In particular, the ring body must be removed and aligned.
  • an impeller block is known in a further embodiment, which is characterized essentially by the fact that the bearing for the impeller are used directly in seats, which are provided in recesses of the housing.
  • the bearings are removed after loosening a retaining ring laterally from the recesses.
  • the circumferential seating surface for the bearing must be opened.
  • a laterally closing the housing plate is removed.
  • projecting webs are arranged, which form a part of the seat surface for the bearings in the mounted state of the plate.
  • the impeller has on both sides exiting stub shafts, on each of which an encapsulated bearing is arranged.
  • the bearings are limitedly displaceable on the stub shaft between stops.
  • For attachment of the impeller between two parallel and spaced support plates of the crane each two strong flat holding pieces are arranged on the outer sides of the support plates, which have concentric with the shaft stubs of the impeller aligned disc-shaped recesses in the installed state of the impeller.
  • downwardly facing slots are arranged, whose width is slightly larger than the diameter of the stub shaft.
  • the impeller For assembly of the impeller can then be inserted from below into the slots with outwardly shifted encapsulated bearings the stub shaft. Subsequently, the encapsulated bearings are positively pushed onto the stub shaft in the direction of the respective retaining plates until they engage positively in the disc-shaped recess. The encapsulated bearings are then bolted to the retaining plates and carrier plates.
  • bearing flanges completely surround the rolling bearing and also the impeller shaft in the circumferential direction.
  • holes are provided in the respective side walls of the crane head, to which in each case in the horizontal direction and in the direction of the end of the head carrier is followed by a slot.
  • This slot serves the wheels together with its impeller shaft to mount in the crane carrier.
  • the wheels are guided with their laterally excellent impeller shafts from the front side of the end of a crane overhead carrier in the slot until they reach the hole in the side wall of the head carrier.
  • the bearings are pushed with the bearing flanges from both sides in each case on the impeller shafts of the wheels until the bearing flanges come to rest on the outsides of the sides of the head carrier and in the bore in the side wall of the head carrier.
  • the bearing flanges are bolted to the side walls of the head support and thus fixed there. The removal and installation of the wheels thus takes place to or from the front ends of the head support and the wheels protrude in the installed state in the direction of the rail down, ie offset in the present case by 90 ° to the installation and removal direction, from the crane overhead ,
  • the present invention is therefore based on the object to facilitate the assembly or disassembly or replacement of the impeller in a wheel block.
  • the pivot bearing seats are designed such that they surround the sliding and / or rolling more than semicircular and forming a bottleneck to the side forming in relation to the sliding and / or rolling bearings, and that the impeller in the installed state To this side protrudes from the housing, it is possible to reduce the assembly costs. Furthermore, there is no need for an additional fit per bearing side, so that a higher accuracy of the wheel alignment and a higher repeat accuracy when changing the impeller are achieved. As a result, lower skew forces occur and, consequently, less wear on the impeller.
  • the not completely enclosed recesses have a constriction which has slightly larger dimensions than the diameter of the hub of the impeller.
  • the sliding and / or rolling bearings can be made smaller than the not completely enclosed recesses and larger than the bottleneck.
  • the recesses are open to the side so that the impeller after lateral removal of the sliding and / or roller bearings can be expanded to the side.
  • the page is preferably the down side.
  • the recesses can be seen in section have about a keyhole-shaped shape.
  • the recesses of the impeller block advantageously have an approximately circular upper area for receiving the sliding and / or rolling bearings and a, in particular forming an angle open to the side, the lower area, which adjoins the upper area at the bottleneck. This allows a good determination of the bearings and high stability and good absorption of forces and still safe and easy installation and attachment of the wheel.
  • the approximately circular upper portion of the recesses describes about a three-quarter circle in section.
  • the pad may be provided on each side of the housing from which the impeller does not protrude.
  • it is a head connection surface which is arranged on the upper side of the housing.
  • FIG. 1 shows a designated as a whole by 1 wheel block with a downwardly open, box-shaped, one-piece housing 2, at its top a head connection surface 3A is provided, which is formed by two respective outer raised surfaces extending across the width of the housing and are separated in the longitudinal direction by a lowered area of the upper housing wall 2A.
  • the housing 2 also has longitudinal sides 2B and end faces 2C, which also have raised surfaces 3B and 3C.
  • Surface 3C is used to fasten roller guides and buffers.
  • the underside is labeled 3D or 8 respectively.
  • an impeller 6 is provided, which rotates with its hub 7 about the axis A and protrudes down to the side 8 partially out of the housing 2. In the usual installation position, the axis A is aligned horizontally.
  • the hub 7 is mounted laterally in each case in sliding and / or roller bearings 5, which are inserted into the housing 2.
  • pivot bearing seats 4 are provided, which are formed directly in the housing by the surfaces of the recesses 9. They have an upper region 11 which is circular in section and a lower region 12 which forms an angle which is open towards side 8 or bottom side 3D.
  • the recesses 9 are therefore not completely enclosed by the housing wall and have an approximately keyhole-shaped longitudinal section.
  • the hub 7 is thus inserted from below into the recesses 9 and their upper, in section circular regions 11.
  • the impeller 2 Due to the design of the impeller block 1, the impeller 2 is mounted with its hub 7 together directly in the housing 2, without the use of ring bodies is necessary. This facilitates the assembly on the one hand. It accounts for each bearing side additional parts such as fits. Furthermore, a higher accuracy of the wheel alignment and a higher repetition accuracy when changing the wheel is allowed by the direct storage. Thus occur lower skew forces and accordingly a lower wear on the impeller.
