Definitions

  • the present invention relates to a receiving arrangement of an excavator tooth with a receptacle for arrangement on a bucket knife of a bucket of a bucket wheel excavator, the excavator tooth having a tooth head and a receiving shaft adjoining the tooth head, and wherein the receptacle has a receiving opening for receiving the receiving shaft.
  • the EP 0 584 101 B1 discloses, by way of example, a receiving arrangement of an excavator tooth with a receptacle for arrangement on the bucket of a bucket wheel excavator.
  • the excavator tooth has a tooth head and a receiving shaft adjoining the tooth head, the receptacle having a receiving opening for receiving the receiving shaft. If the receiving shaft is inserted into the receiving opening, a securing element serves to prevent the receiving shaft from coming loose again from the receiving opening.
  • U1 is a tooth arrangement for attachment to an excavator bucket comprising a tooth and a tooth holder with a clip-shaped fastener known.
  • the excavator teeth of a bucket wheel excavator are subject to heavy wear and therefore have to be changed often and within short production downtimes, depending on the application.
  • the defective or worn excavator tooth must be removed from the holder and a new excavator tooth must be inserted into the holder.
  • Typical tooth fastening systems for bucket wheel excavators which allow the worn tooth to be replaced within a very short time, usually consist of three main components.
  • the excavator tooth and the holder are generally simply wedged in the support area and are only secured without gaps in their longitudinal tooth axis with the help of the securing element.
  • the receptacle is in turn usually inseparably attached to the bucket of the bucket wheel excavator, for example by a weld seam that inextricably connects the receptacle to a bucket knife.
  • the object of the invention is to develop a receiving arrangement for an excavator tooth in a receptacle for arranging a bucket of a bucket wheel excavator, the receiving arrangement should have a simple design and the excavator tooth should be able to withstand changing loads. In addition, the excavator tooth should be able to be easily replaced in the holder.
  • the receptacle has a U-shaped receiving body which is arranged on a blade contact surface of a blade of a shovel, the receiving body having two contact surfaces which are spaced apart and inclined to one another, wherein the contact surfaces and the blade knife contact surface form a triangular arrangement with respect to one another.
  • the development of the receiving arrangement according to the invention makes it possible to accommodate an excavator tooth in such a way that the excavator tooth can absorb both the main digging forces and side digging forces and transfer them into the receptacle of the receiving arrangement without the excavator tooth being able to loosen prematurely in the receptacle.
  • the contact surfaces aligned with one another in a triangular arrangement enable force transfer from the receiving shaft of the excavator tooth into the receiving opening of the receptacle, with the force transfer being advantageously possible both in the main digging direction and additionally in the lateral direction, without the contact surfaces having to be manufactured with great manufacturing effort must be dimensioned relative to each other.
  • the triangular arrangement has an end face arranged opposite the blade contact surface in the manner of a roof surface, the end face being arranged in such a way that the triangular arrangement comprises/forms a trapezoidal geometry.
  • the roof surface is preferably contact-free, i.e. without a supporting function with regard to the excavator tooth.
  • the receiving body defines at least five surfaces comprising the two contact surfaces which are inclined to one another, wherein the two contact surfaces which are designed to be inclined to one another are arranged in the second and fourth positions and, together with the blade blade contact surface, form the triangular arrangement.
  • the surfaces between the contact surfaces are preferably non-contact side surfaces, i.e. without a supporting function with regard to the excavator tooth. These side surfaces are arranged between the two contact surfaces, which are inclined to one another, and the blade contact surface.
  • the two contact surfaces which are inclined to one another, are each between opposite receiving shaft surfaces and are arranged between an end face arranged opposite the blade blade contact surface.
  • the end face is preferably contact-free, i.e. without a supporting function with regard to the excavator tooth.
  • the triangular arrangement has the geometry of a capped, flattened roof in cross section, or has a trapezoidal geometry. This provides an advantageous geometric arrangement.
  • the two contact surfaces which are inclined to one another, are enclosed by opposite receiving shaft surfaces and an end face arranged opposite the bucket blade contact surface, the proportion of non-contact surfaces in the receiving arrangement in relation to the proportion of surfaces (16) contacting the excavator teeth being at least 50%, preferably is at least 75%, and particularly preferably is greater than or equal to the total contact areas.
  • the cross-sectional lengths of the contact surfaces can be at least 50% or at least 75% of the cross-sectional length of the end face. This also provides an advantageous geometric arrangement. In particular, it is provided that the cross-sectional lengths of the contact surfaces are at least 25% or at least 50% of the cross-sectional length of the receiving shaft surfaces.
  • the two contact surfaces which are inclined to one another and have opposite receiving shaft surfaces, each enclose an angle in the range of 110° to 160°, preferably 120° to 150°, more preferably 125° to 145°. This provides an advantageous geometric arrangement.
  • the two contact surfaces which are inclined to one another, each enclose an angle in the range of 110° to 160°, preferably 120° to 150°, more preferably 125° to 145°, with an end face arranged opposite the blade contact surface. This provides an advantageous geometric arrangement.
  • the respective receiving shaft surface can be arranged at least approximately orthogonally to the blade contact surface, in particular exactly orthogonally.
  • the receptacle has the U-shaped receiving body and a contact plate, wherein the receiving body has the two contact surfaces which are spaced apart and inclined to one another and the contact plate has a further contact surface, and the three contact surfaces form a triangular arrangement with respect to one another.
  • the contour of the contact surface of the contact plate correlates with the contour of the blade contact surface of the blade knife. This allows, for example, that the contact plate can lie or be arranged on the blade contact surface without a gap. Gap-free means that there are no gaps between the surfaces so that optimal force transmission can take place.
  • the contact surfaces which are produced on the inside in the receiving opening of the receiving body, can be milled in a simple manner, and the contact plate can have a contact surface which the contact plate already has in the state of a semi-finished product.
  • the contact plate then only needs to be brought to the desired size, and the contact plate can be arranged on the U-shaped receiving body in such a way that the two contact surfaces in the receiving opening of the receiving body and the contact surface on the contact plate form a triangular arrangement with one another and a corresponding positional tolerance to one another form.
  • the three surfaces do not have to intersect, and the three surfaces can be limited in such a way that they are designed at a distance from one another.
  • the triangular arrangement is created solely by the alignment of the contact surfaces to one another, for example by the two contact surfaces in the receiving body being designed as roof surfaces and forming cathedrals, so that the contact surface on the contact plate forms a hypotenuse, which is to be viewed as a base surface, so that the two contact surfaces are in the Receiving body extends like a roof over the contact surface on the contact plate.
  • the shovel knife contact surface or the contact plate is arranged on the receiving body in such a way that an opening side of the U-shape of the receiving body is at least partially closed with the shovel knife contact surface or the contact plate.
  • the inner wall of the receiving opening in the receiving body and the contact plate form a closed inner contour for receiving the receiving shaft of the excavator tooth.
  • the receiving opening has a longitudinal opening axis along which the receiving shaft can be inserted into the receiving opening.
  • the contact surfaces of the receiving body and the contact surface of the contact plate or the blade blade contact surface can point towards the longitudinal axis of the opening.
  • the two mutually inclined contact surfaces, which form part of the inner contour of the receiving opening, do not have to intersect in a common edge, and a further roof surface can be provided above the contact plate, so that the cross-sectional shape of the receiving opening forms approximately a trapezoid.
  • the receiving body has a mouth side through which the excavator tooth can be inserted to arrange the receiving shaft in the receptacle.
  • the contact surfaces can converge towards one another with increasing distance from the mouth side along the opening longitudinal axis of the receiving opening, so that they can form the surfaces of a three-sided pyramid or a square trapezoid in cross section, in particular a square with a flat top. Consequently, the cross-sectional area becomes the trapezoidal shape of the receiving opening above the contact plate becomes smaller as the distance from the mouth side of the receiver increases.
  • the contact plate is particularly advantageous for the contact plate to be welded to the receiving body and/or to the blade.
  • the receiving body can have welding bevels formed on the outside on the edges, via which the receiving body can be welded to the blade of a bucket wheel excavator.
  • the contact plate can first be welded to the receiving body in order to then weld the composite of the receiving body and the contact plate to the bucket of the bucket wheel excavator, in particular to a bucket knife.
  • the two contact surfaces on the receiving body which are spaced apart and inclined to one another, can be machined. Furthermore, a receiving groove on the respective legs of the U-shaped receiving body can be machined for welding the contact plate in order to enable precise positioning of the contact plate on the receiving body, in particular using the reference body in the form of the receiving shaft.
  • the two contact surfaces which are inclined to one another, can each be arranged between opposite receiving shaft surfaces and between an end face arranged opposite the blade blade contact surface. This provides an advantageous geometric arrangement.
  • the two contact surfaces which are inclined to one another, can each be arranged with opposite receiving shaft surfaces at an angle in the range of 125 to 145 °. This provides an advantageous geometric arrangement.
  • the two contact surfaces which are inclined to one another, can each be arranged at an angle in the range of 125 to 145 ° with an end face arranged opposite the blade contact surface. This provides an advantageous geometric arrangement.
  • the invention is further directed to a method for forming a receiving arrangement of an excavator tooth with a receptacle for arrangement on a bucket knife of a bucket of a bucket wheel excavator, the excavator tooth having a tooth head and a receiving shaft adjoining the tooth head, and wherein the receptacle has a receiving opening for receiving of the receiving shaft, and wherein a shovel has a shovel knife with a shovel knife contact surface.
  • the method according to the invention provides the following steps: creating two contact surfaces that are spaced apart and inclined to one another in an area of the U-shaped receiving body that lies inside the receiving opening, arranging the receiving body on the blade blade contact surface, so that an opening side of the U-shape of the receiving body is connected to the blade blade contact surface is at least partially closed and the three contact surfaces form a triangular arrangement with one another.
  • a preferred measure of the invention is characterized by providing a contact plate with a further contact surface on the blade blade contact surface and arranging the contact plate on the receiving body, so that an opening side of the U-shape of the receiving body is at least partially closed with the contact plate and the three contact surfaces form a triangular arrangement form to each other.

  • the contact plate can be welded to the receiving body, with a reference body in the form of the receiving shaft being able to be inserted into the receiving opening in order to position the contact plate on the receiving body.
  • This allows an exact, closely tolerated receiving opening to be created in the holder, in which the receiving shaft of the excavator tooth can be received without play. Due to the initially open accessibility of the internal area of the receiving body, the Contact surfaces are machined, and only then is the contact plate welded to the free ends of the legs of the U-shaped receiving body. Finally, as a final step, the composite of the receiving body and the contact plate can be attached, in particular welded, to the bucket of the bucket wheel excavator.

Furthermore, the contact surfaces 16 and the blade blade contact surface 26 also form a triangular arrangement with respect to one another.
  • the weld seams 23 for fastening the contact plate 15 to the receiving body 14 merely serve to form a closed contour of the receiving opening 13 with correspondingly narrow tolerances, and forces that act from the receiving shaft 12 in the direction of the contact plate 15 can be transferred directly into the rigid blade 22 become.
