Definitions

  • the blade elements and integral therewith executed annular base body be designed appropriately massive ⁇ lead.
  • the undesirably high use of material increases the overall weight and manufacturing costs of a jet engine, which is not desirable.
  • the present invention is therefore based on the object to provide a method for producing a one-piece rotor section, preferably a jet engine, avail ⁇ supply, by means of which one-piece rotor sections with high resistance to foreign body damage and against vibration loads at the same time low component weight can be produced.
  • the invention has for its object to provide a one-piece rotor area available, which is characterized by a high resistance to foreign body damage and vibration loads, is inexpensive to produce and whose surface is designed with a low roughness. According to the invention this object is achieved with a method having the features of claim 1 and with a einstü ⁇ ckigen rotor portion having the features of patent claim. 9
  • the hydraulic pressure is applied to the drive device 20 and a piston element 23 moves out of a cylinder element 24 of the drive device 20 due to the applied hydraulic pressure, whereby a distance between the ends 25 facing away from the rolling regions 21 and 22 results from such a change in operating state of the drive device 20 and 26 the pliers body 17 and 18 is increased, while the distance between the Wälz Schemeen 21 and 22 is reduced in accordance with the geometric conditions in dependence of the rotational movement of the pliers body 17 and 18 to the pivot bearing 19 around.
  • the pliers body 17 and 18 are each rotatably connected to the drive device 20 in the region of their ends 25 and 26.

Abstract

Procédé de fabrication d'une partie de rotor (9) monobloc, de préférence d'un réacteur (1). Cette partie de rotor (9) comprend un corps de base (10) annulaire et plusieurs éléments aubes (11) répartis sur la périphérie, ces éléments aubes s'étendant sensiblement dans le sens radial à partir du corps de base (10). Un outil de laminage pénétrant entre les éléments aubes (11) permet d'introduire des contraintes propres dans lesdits éléments aubes (11) par galetage de renforcement dans des zones proches de la surface. Lors du galetage de renforcement, une zone respective de l'élément aube (11) est disposée entre des zones de l'outil de laminage et les faces longitudinales de l'élément aube (11) sont galetées simultanément. Selon l'invention, l'outil de laminage est introduit radialement entre les éléments aubes (11) et les surfaces des éléments aubes sont galetées. Ainsi, au moins les éléments aubes (11) présentent une surface usinée par galetage de renforcement.
