Abstract

A receiving element which can be introduced into a borehole of at least one component includes a bolt presenting an outer surface that is approximately parallel and advantageously coaxial to a longitudinal axis of the bolt. The receiving element requires few materials and can therefore be produced at a low constructional cost while being provided with high dimensional stability and positioning accuracy. The bold includes an abrasion-resistant sintered material, and a metal tip provided on the front end of the shaft. The end part of the tip is engageable in a recess of the bolt, and there is a direct connection between the end part and the recess in the connection region on the front end of the bolt.

       11 . A receiving element, comprising: 
 a bolt having an exterior surface that is substantially parallel to a longitudinal axis of the bolt and that can be introduced into a bore in at least one component, said bolt including or containing wear-resistant sintered material and including a recess at a forward end thereof; and    a tip comprised of metal arranged at the forward end of said bolt, the tip including an end section which engages in said recess of said bolt, a direct connection between said end section of said tip and said recess in said bold existing in a connecting area provided at the forward end of said bolt which extends only over a portion of an entire length of said bolt, said tip further including a forward section which projects axially out of said bolt, a transition area being interposed between the forward section of said tip and the forward end of said bolt, said transition area tapering to said forward section of the tip in a manner such that the receiving element has a stepped exterior contour, said forward section having a maximum external diameter that is less than a corresponding exterior diameter of said bolt by a prescribed amount.    
   
   
       12 . A receiving element according to  claim 11 , wherein said exterior surface is coaxial with said axis.  
   
   
       13 . A receiving element according to  claim 11 , wherein said at least one component includes at least two components.  
   
   
       14 . A receiving element according to  claim 11 , wherein said end section of said tip is joined in said recess to said bolt by at least one of an adhesive joint, shrink fit, press fit or clamp connection.  
   
   
       15 . A receiving element according to  claim 11 , wherein said end section which engages in said recess has an external diameter that is smaller by a prescribed amount than the maximum external diameter of said forward section.  
   
   
       16 . A receiving element according to  claim 11 , wherein a step is provided between said forward section and said end section of said tip that defines an axial stop with respect to said bolt.  
   
   
       17 . A receiving element according to  claim 11 , wherein said forward section has an exterior surface that tapers substantially conically toward a free end with a prescribed takeout angle.  
   
   
       18 . A receiving element according to  claim 11 , wherein said exterior surface of said transition area has a transition takeout angle that is substantially greater than the substantially conical takeout angle of said forward section.  
   
   
       19 . A receiving element according to  claim 11 , wherein said exterior diameter of said bolt is in a range of 3 to 12 mm.  
   
   
       20 . A receiving element according to  claim 19 , wherein said range is 3.5 to 10 mm.  
   
   
       21 . A receiving element according to  claim 20 , wherein said range is 4 to 8.5 mm.  
   
   
       22 . A receiving element according to  claim 11 , wherein said bolt includes a fastening body that is an integral component of said bolt and that comprises a same material as said bolt, said fastening body being disposed at an other end said bolt opposite to said forward end.  
   
   
       23 . A receiving element according to  claim 22 , wherein said fastening body includes a flange having an external flange diameter which is larger than said external diameter of said bolt.  
   
   
       24 . A receiving body according to  claim 11 , further comprising a fastening body comprised of an electrically insulating material disposed at an other end said bolt opposite to said forward end.  
   
   
       25 . A receiving element according to  claim 24 , wherein: 
 said bolt includes a second recess; and    said fastening body includes a connecting section that engages in said second recess.    
   
   
       26 . A receiving element according to  claim 24 , wherein said connecting part is joined directly to said bolt by means of at least one of an adhesive joint, a shrink fit, a press fit or a clamp connection.  
   
   
       27 . A receiving element according to  claim 24 , wherein said fastening body includes a flange having an external flange diameter which is larger than said external diameter of said bolt.  
   
   
       28 . A receiving element according to  claim 27 , wherein: 
 said bolt includes a second recess; and    said fastening body includes a connecting section that engages in said second recess.    
   
   
       29 . A receiving element according to  claim 28 , wherein said connecting part is joined directly to said bolt by means of at least one of an adhesive joint, a shrink fit, a press fit or a clamp connection.  
   
   
       30 . A receiving element according to  claim 11 , wherein said wear-resistant sintered materials comprise oxide ceramics or non-oxide ceramics.  
   
   
       31 . A receiving element according to  claim 30 , said ceramics include Al 2 O 3 , ZrO 2 , or Si 3 N 4 , or mixtures thereof.  
   
   
       32 . A receiving element according to  claim 11 , wherein said portion of the entire length of said bolt extends over less than 50% of said entire length.  
   
   
       33 . A receiving element according to  claim 32 , wherein said portion of the entire length of said bolt extends over less than 30% of said entire length.
