Description

The invention relates to an impeller block with a Housing in which the pivot bearing seats for sliding and / or rolling bearings for the inclusion of at least one one side of the protruding impeller is provided, the housing in order to remove the sliding or Rolling bearing and / or the impeller at least according to egg can be disassembled into housing parts and reused is binding.

Such an impeller block is made by Man nesmann Demag Fördertechnik AG under the designation RS manufactured and distributed. Such a run wheel block is also from DE 31 34 750 C2 be knows.

The well-known wheel block is composed of two welded or otherwise joined halves the bearing housing is formed and faces inwards pressed rotary bearing seats for bearings in which the Na be supported by the impeller. Close here towards the hub on the pivot bearing seats Contact surfaces for the bearings and the impeller is enough with his hub over the bearings and is over supported directly on the housing, and the hub points ring grooves for their outer rings on both sides snap rings on the end faces of the bearings and a receiving opening with an internal toothing for an external toothing of a drive shaft on.

This design has been in practice for years lasts. However, there is still a need for Minimizing costs and improving functionality.

A disadvantage of the known impeller block is that to replace the impeller the impeller block in full of the supporting structure constantly has to be solved.

After changing the impeller, the entire Impeller block back on the structure - just like for the first assembly - fastened with screws. There to the impeller block but in its position relative aligned to the structure with the other impellers be tet so that the axis of rotation of the impeller is right at an angle to the running track on which the running wheel rolls, runs. This assembly process is due to the expense aligning time-consuming, which makes the still extended service life of the entire machine, and thereby also conditionally expensive. When aligning is not carried out, there is a risk that the wheels by skewing on the track grind (rub off) and wear out faster. Furthermore, there is a bridge in the application cranes the danger that the running behavior of the bridges Cranes sensitive due to skewing, bumping and Flange wear is disrupted. In addition, join increasing slip angle lateral forces that the Structure or the like over the operational load from strain. This problem is discussed in detail in the DIN 15 018.

The present invention is therefore based on the object based on manufacturing and assembly costs by a white Developed design of an impeller block to mi diminish and thereby increase customer benefit, that the above Disadvantages of the known impeller block ver be avoided.

The object is achieved according to the invention solved the features of claim 1.

The present invention enables the replacement of the impeller and / or the bearing without that the housing must be detached from the structure. This eliminates the time-consuming and costly alignment process following the replacement of Ver wear parts, the housing is reusable and remains aligned with the structure or the like, as long as this is desirable.

There is also the advantage of a detachable connector to use insoluble means because that block-shaped housing from the carrier in question or moving frame no longer has to be solved.

Another advantage is that the newly developed Impeller block completely demon in its components can be recycled and recycled. This is particularly true in With regard to rising disposal costs and the after Separate disposal of materials is advantageous.

According to further features, it is provided that the Head interface in overlay and not overlying sub-areas is divided. This will make the Force transmission is more defined than before, and it is at the manufacture of the impeller block significantly at Zer cutting power or cutting volume saves.

It is also advantageous that an overlying partial surface is undivided, d. H. has no parting line. The level the surface of a homogeneous material and smaller sub-areas correspond to connection areas accordingly more precise than with several or large partial areas chen. Furthermore, the smaller subareas Forces defined in the adjacent structure. This leaves an optimized training of the Anschlusskon structure with known power flow.

In that at least one detachable Dec is attached to the rotary bearing Is centered, becomes a side Removal of the bearings and / or the impeller possible. The lateral expansion reduces the disassembly and Mon day effort of the impeller in that now Structure, the girder or the moving frame only who is raised by the wheel flange height of the impeller that must.

Other advantages result from the fact that the head pad one or more openings has the advantage that the Impeller radius by more than the thickness of the upper plat limit can be increased. White is advantageous terhin that the breakthrough dirt deposits too in the event that the housing with the open opposite side from which the impeller protrudes the direction of gravity (upwards).

However, it is also possible that the breakthroughs with means are in turn closable where these are not made of the same material as the Ge housing must be made, since they have neither load capacities still take up of appropriate stress must be able. Prevent the locking pieces the ingress of dirt or other pollution cleaning in the event that the housing with the open side, on which the impeller protrudes, in Gra direction of growth (downwards).

In an embodiment of the invention it is provided that the head pad with at least one recess  is provided, which ver parallel to the impeller axis running. This allows prefabricated bolts to be used be, with an inaccurate hole pattern of the counter piece is possible without this leading to disadvantages, because the bolts move in the recess and can adapt to the inaccurate hole pattern.

The said recess can also be used as a groove tion, as a through hole or as a threaded hole be trained. Depending on the accuracy of the connection the appropriate passage type can be selected become.

Further advantages result from the fact that in the groove guides Locknuts for connecting screws across adjustable and guided with little play. This execution The form of the connection serves to facilitate the connection and alignment during initial assembly between the framework, girder, traveling frame or the like and the Impeller block housing.

The structure of the housing is asymmetrical, whereby ver at least one cheek surface by means of a lid is closable and the width of the housing is a ches the thickness of the lid. Such a lid has several advantages because it is simple, flat shaped part can be designed differently. He is used to form interlocks, the cultivation of Sensor elements and can be used as an adapter for connection be formed with a drive unit.

On the basis of the invention, it is assumed that the width of the case is two to forty times the thickness of the lid is. This allows rows be detected by housing levels.

This will make it easy to remove the cover achieved that the lid to the head pad is low is scheduled.

The same advantage arises when the lid spring back at least to an end pad is trained.

This provides an advantageous power transmission instead of the cover being provided with centering hubs which in corresponding holes in the housing fen.

It is also suggested that the cross section the cover is outside the impeller diameter thickened. Fasteners can be used in these areas tel, spacers u. Like. Be attached. This one the required material is pending at these points amply available.

Accordingly, it is advantageous that countersinks for screw heads and nuts in the thicker cross section of the lid are arranged.

The fasteners can e.g. B. advantageously se consist in that the counterbores hexagon shape have alternating either an inner six Pick up the square head or a hexagon nut.

It is also provided that the centering hubs with Verse internal holes for receiving support bolts hen that are concentric to the centering hub. This design contributes to good power transmission to support the reaction forces in the housing of the Impeller block at.

There are also manufacturing advantages through that the centering hubs corresponding Boh stanchions in the housing and the inner bores with their common axis each outside the scope of the Run the impeller parallel to the impeller axis. A sol ches system is accordingly low tolerance and therefore economically producible.

Another embodiment provides that in the housing on the side opposite the lid Take hub for a pivot bearing to accommodate the inside rings or the outer ring is formed. Thereby the pivot bearing can easily tolerate its ge be brought to the right location, what by appropriate Manufacturing technology is made possible.

According to other features, it is proposed that a hub for a pivot bearing on the cover to accommodate the inner ring or the outer ring is formed. This measure also serves the production technically favorable production as well as the simple Assembly or disassembly.

Other characteristics go that upside down final area the housing receiving means for connection funds are provided. Through the means of reception an adjustment of the connecting means accordingly the setting of the entire impeller block be taken.

In addition to those provided on the head pad Groove guides with locknuts are also an exception conditions on the front connection surfaces of the housing hen. This means that additional elements can be connected, without finally occupying the front connection surface. It is also possible, even the whole wheel block on this End face of the housing to a carrier or To connect traveling frames or the like.

According to further features, it is provided that the Recesses generally as a groove guide, as Through hole or threaded hole forms are. Depending on which lanyard in Combination with which admission means the cheap most assembly and the most accurate possible location, the appropriate combination can be selected the.

Furthermore, it is provided that the head end face opposite outer surface of the Ge housing from which the impeller protrudes, at least one Partial pad is formed. At this partial connection Surface can therefore also other units, such as. B. Guide rollers, measuring devices. u. Like. Connected will be. This partial connection surface can also be so ge stalten that the whole wheel block on this Area with the supporting structure, girder or moving frame can be connected.

For this attachment of other units is advantageous adheres to the outer end pads of the housing are undivided and each have a receiving surface represent for load capacities.

To get an exact location and to make mistakes in to avoid storage, it is also provided that the lid with the housing shape and / or force conclusively using lanyards and using Zen trier hubs is connected.

To avoid corrosion or to gain weight save, it is proposed that the housing and / or the lid from a molten state too processing material. For that come into special light metal materials and plastics in Consideration.

To ensure that the component in question is a has the desired resilience seen that the material from a light metal Le government exists.

It can also be advantageous that the material is made of an iron alloy, if the corresponding Fe stances are required.

It can make sense for economical processing  be full that the material from a plasticizable Plastic is made.

In this regard, it may be desirable that both sufficient strength of the components as well low weight must be achieved. To do this suggested that the composite material exists or with other materials a composite measure material forms.

An impeller block ( Fig. 1 and 2) has a housing 1 , in the pivot bearing seats 2 (see. Fig. 6) for sliding and / or rolling bearings 3 are provided for receiving an ordinary Lich protruding downward impeller 4 . For the purpose of removing the sliding and / or rolling bearings 3 and / or the impeller 4, the housing 1 can be disassembled into housing parts and reconnected at least on one side, with a carrier or traveling frame 5 (see FIG. 8) determining the direction of removal. The impeller block is attached to such a carrier or frame 5 as will be described later.

The housing 1 is block-shaped, ie viewed from the side and from above or below, either square or rectangular or also trapezoidal. The basic shape can resemble a cuboid.

This block-shaped housing 1 has at least ei ne the supporting force (the impeller 4) receiving, located approximately to the housing width 6 and the impeller width 7 extending head pad 8 on the sides 8a, the connecting means 9 (z. B. Compound screws 9 a, nuts, Bolts, rivets and the like) - cf. Fig. 8 - between the housing 1 and the to be connected to the wheel block carrier, frame 5 or the like. Angeord net.

The head connection surface 8 and / or a cheek surface 10 and / or a front connection surface 11 are subdivided into lying and non-lying partial surfaces 12 and 13 (see FIGS. 2 and 7). The surface Teilflä Chen 12 take the respective load capacity or partial load capacity. In this case, an overlying partial surface 12 is itself undivided, although there may be several such overlying partial surfaces 12 . This system of the overlying sub-areas 12 and the sub-areas 13 do not make the position of the entire wheel block after its adjustment to the carrier or traveling frame 5 statically determined, safe and unique. This position can therefore be maintained practically for life before, during and during the exchange of the sliding and / or rolling bearings.

For the exchange process is now at least on one side (cheek surface 10 ) of the housing a releasable cover 14 is attached, which is centered in the operating position to the pivot bearing seats 2 .

For weight reasons, while the load-bearing capacity is retained in full, the head connection surface 8 has one or more openings 15 . The openings 15 can be closed by means of closure pieces 16 , which are made of materials with a low specific weight (cf. FIG. 3).

The head pad 8 is provided with at least one recess 17 (in Fig. 3, two recesses are drawn), which runs parallel to the impeller axis 18 ver. The recess 17 can be guided as a groove guide 19 , as a through hole or as a threaded hole 20 . As shown ( Fig. 3) are in the groove guides 19 locknuts 21 for connecting means 9 , which consist of the connecting screws 9 a.

The housing 1 is constructed asymmetrically for the reasons described above for permanent attachment in the sense that the side cover 14 is provided, the housing width being a multiple of the thickness 14 a of the cover 14 .

The width 6 of the housing 1 can, depending on the size and load capacity of the impeller 4, be two to forty times the thickness 14 a of the cover 14 , the Dec angle 14 to the head connection surface 8 being lower and thus in no way assuming load capacities and easy handling can be dismantled in the load state.

The lid 14 is also formed to a front connection surface 11 recessed and thus does not interfere with a lateral system for the attachment of the impeller block in a different way.

The cover 14 also has integrally formed Zentrierna ben 22 which engage in corresponding bores 23 of the housing 1 .

The cross section 14 b of the cover 14 is thickened outside the impeller diameter 4 b. Countersinks 38 for screw heads 39 and nuts 40 are incorporated into these thickenings. The countersinks 38 can have a hexagonal shape 41 , with either an internal hexagon head 42 ( FIG. 1) or a hexagonal nut 43 ( FIG. 4) being used alternately.

The centering hubs 22 are equipped with inner bores 24 . The inner bores 24 take Tragbol zen 25 and are concentric with the centering hub 22nd

The centering hubs 22 , the corresponding bores 23 in the housing 1 and the inner bores 24 each run with their common axis 26 outside the circumference 4 a of the impeller 4 (see FIG. 1) parallel to the impeller axis 18 .

In the housing 1 , a receiving hub 28 ( FIG. 6) for a rotary bearing 29 for receiving the inner ring 29 a or the outer ring 29 b is integrally formed on the side 27 opposite the cover 14 .

On the cover 14 , a receiving hub 30 ( FIG. 6) for a rotary bearing 29 for receiving the inner ring 29 a or the outer ring 29 b is then formed in an analogous form to the housing 1 .

On the head connection surface 8 ( FIG. 3) and / or on the outer end connection surfaces 11 ( FIG. 2) of the housing 1 , receiving means 31 for the connecting means 9 are arranged. In addition to the surface 8 provided on the head connection groove guides 19 with locknuts 21 there are also recesses 32 on the end connection surfaces 11 of the housing ( FIG. 2).

The recesses 17 and 32 ( FIGS. 2 and 3) are each equipped as groove guides 19 and designed either as a through hole 33 or as a threaded hole 20 .

In addition to the head connection surface 8, the housing 1 has an outer surface 34 , which is shown in view in FIG. 7. This outer surface 34 is divided into part connection surfaces 35 .

In contrast, the outer Stirnanschlußflä surfaces 11 of the housing 1 are undivided ( Fig. 2) and each represent a receiving surface 36 for load capacities.

The lid 14 is connected to the housing 1 on the Zen trier hubs 22 ( Fig. 5) positively and non-positively via connecting means Ver, the connecting means z. B. consist of connecting screws.

Housing 1 and cover 14 can each be injection molded or cast from molten materials. Manufacture by forging is also possible. The material can e.g. B. consist of a Leichtme tall alloy. An iron alloy can also serve as a high-strength material. At lower loads or load capacities, the material consists of plasticizable plastic. The load capacity of the wheel block is higher for materials made of composite material or materials that form a composite material with other materials.

In Fig. 9 it is clear that the displaceability of the receiving means 31 in the groove guide 19 together with the connecting means 9, a permanent adjustment of the wheel block on the Fahrrah men or the carrier 5 or the like can be created.
