Definitions

  • the invention relates to a compressor wheel attachment for high-speed turbomachinery according to the preamble of claim 1.
  • Compressor wheels of turbomachinery are either non-positive or positive connected to their drive shaft. With increasing pressure conditions and consequently with increasing operating torques and high peripheral speeds is a positive torque transmission, i.e. a form-fitting Shaft-hub connection of the compressor wheel advantageous.
  • a positive compressor wheel attachment is known from EP 05 22 630 B1, which is realized by means of a multi-spline shaft. With this solution it is Lifespan of the shaft-hub connection due to the insertion through the keyways Notches restricted. In addition, additional centering elements are required which increase the cost of the compressor wheel. As a result of the manufacturing-related Such a shaft-hub connection must have inaccuracies of multi-spline shafts always be balanced as a unit, the parts being identical for the purpose Reassembly must be marked accordingly. So the stake is of the compressor wheel with another, not balanced together with this Wave not possible. However, this is a crucial disadvantage when servicing.
  • Positive compressor wheel attachments using a thread are both from US 3,961,867 and also from WO 93/022778.
  • the loosening torques required for disassembly reach double the Operating torque.
  • Such forces can only be achieved using special tools or be applied by means of a transmission gear.
  • a there is another disadvantage of fastening the compressor wheel by means of a thread in that when assembling the compressor wheel the first with the shaft thread touching areas of the hub thread up to their End position must travel a relatively long way on the shaft thread.
  • the invention tries to avoid all of these disadvantages. You have the task based on a safe and reproducible compressor wheel attachment for high-speed To create turbo machines, which also have an improved torque transmission owns.
  • both in the through hole of the compressor wheel arranged hub cone as well as the corresponding one Shaft cone each have an average diameter and these mean diameters at an axial distance from the center of mass of the compressor wheel are arranged, which is at least half the middle Corresponds to diameters.
  • the through hole of the hub is on the shaft side of the hub cone is at least partially designed as a cylindrical bore.
  • the hub and shaft cones i.e. the real ones Fastening elements, outside the center of gravity of the compressor wheel. Therefore are essential in the fastening area of the compressor wheel to record minor stresses due to centrifugal forces or thermal expansion, so that the widening of the hub cone can be significantly reduced. This means that compressor wheel attachment can be secured even at high speeds will be realized.
  • the cylindrical bore arranged on the shaft side serves as Centering seat for the compressor wheel.
  • the through bore of the hub on both sides of the hub cone is particularly advantageous at least partially formed as a cylindrical bore, the second, i.e. the cylindrical bore on the compressor side is an assembly aid.
  • the compressor wheel has one on its rear wall connecting sleeve on the shaft side for the shaft journal.
  • the distance can be particularly suitable for internally mounted turbochargers the fasteners from the center of gravity of the compressor wheel be further enlarged. This leads to an improved compressor wheel attachment, which allows higher speeds without risk.
  • a flat surface is advantageous on the mounting sleeve and a corresponding plan stop is formed on the shaft. So that both clear axial positioning as well as good concentricity of the compressor wheel reached.
  • the shaft journal is formed at least in two parts and consists of the shaft cone as well as one with the centering seat, i.e. with the shaft-side cylindrical Bore, corresponding shaft collar.
  • the shaft journal is formed at least in three parts. He points to that additionally a cylindrical shaft end, which pre-rivets the compressor wheel serves to position it on the shaft journal. As a result of this There is no radial displacement when the compressor wheel is pre-centered of the shaft and the hub cone against each other, so that a Damage to the actual fasteners can be avoided. Ultimately, this leads to an improved shaft-hub connection and thus an increased service life of the compressor wheel.
  • the receiving device is particularly advantageous of the shaft journal in the shaft end, with a two-part shaft journal however arranged in the shaft cone.
  • the receiving devices are as internal threads formed, the internal thread of the shaft end or the shaft cone is smaller than the internal thread of the hub.
  • the assembly / disassembly tool is different as a differential screw with two external threads Incline trained. The one that corresponds to the smaller slope corresponds External thread with the internal thread of the hub and the one with the larger one Inclined external thread with the internal thread of the shaft end or the shaft cone.
  • the differential screw or its differential thread serves both as an assembly / disassembly tool as well as for axially securing the compressor wheel the wave. Accordingly, no additional assembly / disassembly tools are required.
  • the hub cone is on the compressor side the center of gravity of the compressor wheel. This will make it Compressor wheel less stressed by centrifugal forces or thermal expansion than with the arrangement of the hub cone in the center of mass. With this, in particular suitable for the external storage of turbochargers Widening of the hub cone is reduced even further and thus the fastening of the Compressor wheel can be further improved. In addition, a smaller axial length reached.
  • the exhaust gas turbocharger mainly consists of a radial compressor Compressor 1 and an exhaust gas turbine, not shown, which on a common shaft 2 are arranged.
  • the radial compressor 1 has a compressor housing 3, in which a compressor wheel 4 is rotatably mounted on the shaft 2.

  • the hub 6 of the compressor wheel 4 is equipped on the shaft side with a rear wall 13. On the compressor side of the rear wall 13, the compressor wheel 4 has a center of mass 14.
  • the through hole 8 is on both sides of the hub cone 9 formed as a cylindrical bore 15, 16. Both holes 15, 16 are coaxial to an axis 17 of the through hole 8.
  • the solution according to the invention can also be used with an exhaust gas turbocharger can be used with a compressor 1 designed as an axial compressor (not shown).
  • the exhaust gas turbocharger has an inner bearing, i.e. between the turbine or between its likewise not shown Housing and the compressor housing 3 is a bearing housing 18 with an axial / radial bearing 19 arranged in which the shaft 2 is rotatably mounted.
