Definitions

  • the invention relates to the field of shaft / hub connections.
  • Turbochargers to increase the performance of reciprocating engines include a through Engine exhaust driven turbine and one via a torque transmitting Compressor shaft connected to the turbine.
  • Turbocharger for smaller engine outputs advantageously have a radial compressor made of aluminum without continuous Central bore on, as known from DE 44 44 082.
  • the compressor wheel can be solved for manufacturing and maintenance reasons with the Turbine shaft connected.
  • the compressor wheel is either directly or via a Intermediate sleeve made of steel or bronze on a stub shaft with a conventional thread screwed on. At least one offset to the thread Cylindrical or conical centering seat ensures the centering of the compressor wheel regarding the wave.
  • the invention is therefore based on the object, a connection of the beginning to create the type mentioned, which with improved torque transmission allows reduced axial preload.
  • the radial pressure that is decisive for torque transmission is thanks to the flat Angle between the load-bearing, with their large surfaces friction flanks lying on top of each other and the axis correspondingly larger than at conventional threaded connections. This allows the axial preload between the two parts to be connected are reduced accordingly.
  • the flat-shaped supporting flanks enable an improved Centering the shaft attachment and shaft.
  • the shaft attachment is exemplary as one in shape and size approximately Corresponding cylindrical counterpart shown. As a rule, it is in the shaft attachment around a wheel-shaped part, such as the compressor wheel Turbocharger.
  • the shaft has an external thread in the area of the connection point.
  • the external thread at the shaft end in the form of a Threaded pin 10 is formed.
  • the shaft and Shaft attachment For the axial positioning of the shaft attachment with respect to the shaft, the shaft and Shaft attachment an axial stop 11 and 21.
  • the two axial stops have in the Usually with high precision manufactured parallel surfaces, with which they make a significant contribution to the concentricity of the shaft attachment and shaft. Between Axial stops, further parts can be arranged, for example as in the figure shown a sealing or damping disc 3rd
  • FIG. 2 shows a view of a section through the shaft axis compound according to the invention.
  • the two axial stops 11 and 12 are at Screwing the shaft attachment onto the shaft, which causes the Shaft attachment is biased against the shaft.
  • the shaft attachment is usually a larger one, made of a relatively soft one Material manufactured part can in the area of the threaded connection through the Sliding a hard steel sleeve 4 on the shaft extension of the Shaft attachment can be prevented by the threaded pin.
  • the special design of the thread according to the invention is enlarged in FIG. 3 shown.
  • the thread has load-bearing flanks 15 and 25 as well as manufacturing-related, edges 16 and 26 not loaded.
  • the supporting flanks 15 and 25 enclose with the axis A of the shaft and the shaft attachment a very flat angle ⁇ .
  • the Flank angle ⁇ is ideally 5 ° to 15 °, depending on the requirements of the Connection or the material of the parts to be connected, however, also in the range of 0 ° up to 45 ° or even 60 °.
  • the flatter this angle ⁇ the smaller it is axial preload, which can be transmitted through the thread to the two parts to be connected, the shaft and the shaft attachment using the axial stops to brace against each other.
  • the decisive radial pressure for torque transmission is corresponding to a flat angle between the supporting flanks and the axis greater.
  • the large flanks of the load-bearing flanks are friction-locked on each other.
  • the thread according to the invention is used to further reduce the pretensioning force Multi-course, preferably 3-course. Given a given Flank angle less deep thread grooves and therefore less Cross-sectional weaknesses. In addition, a 3-start thread leads due to the 3-fold cyclic Symmetry for an improved centering of the shaft attachment on the Wave.
  • the flat-shaped supporting flanks bring a further improvement in the Centering of the shaft attachment on the shaft.
  • the flat thread according to the invention has significantly larger fillet radii 17 and 27. That’s why Thread according to the invention has practically no notch effect and is dynamic Torque fluctuations are much more resilient than a conventional thread.
  • the thread as shown in the different figures, is a conical thread improves compared to a cylindrical version Force transmission while the screwing distances are shortened.
  • the steeper the angle ⁇ of the Cone the shorter the screw-on distances, since sometimes several are used when screwing on Threads can be skipped.
  • Figures 4 to 7 show detailed individual views of the shaft and the shaft attachment.
  • the Axial views show the three-start thread.
  • the three threads are arranged offset by 120 °.
  • the arrangement of the threaded pin and the bore, or the outer and of the internal thread can also be interchanged, so that on the shaft attachment Threaded pin is arranged and the corresponding hole in the shaft end is let in.
  • the threaded pin need not be designed as a stub.
  • the external thread can be arranged in a central region of a rod-shaped shaft, the bore in the shaft attachment being correspondingly deep for the thread extension, or must be continuous.
