Claims

[Claims for Utility Model Registration] (1) In a device for fixing a wheel 12 to a shaft 14 of a turbomachine 10, the axis of the wheel 12 is fixed so as to define an expandable chamber 38 between the surface of the wheel 12 and the shaft 14 of a turbomachine 10. an outer member 22 disposed forward in the direction and alignment holes 17, 23 drilled in the outer member 22 and the wheel 12;
A plurality of coupling members 24.64 are fixed at one end in the hole 18 of the shaft 14 by passing through the outer member '22 in the axial direction, and the other end is engaged with the outer member 22, and the outer member '22 is moved relative to the wheel. exerting a stretching force on the connecting member 24.64;
Thereby, the force-generating means for creating a force in the expandable chamber 38 to apply a compressive force to the wheel 12 and force it against the shaft 14 and the force-generating means can be removed. and retaining means 28.76 for maintaining said tensile force exerted on the connecting member and compressive force exerted on the wheel 12 so as to. (2) the expandable chamber 38 is connected to a first radial surface 44 of the wheel 12 and a second radial surface 42 of the outer member 22 opposite the first radial surface;
2 and a second annular surface of the outer member 22 opposite the first annular surface;
The fixation device of claim 1, wherein a seal 40 is interposed between the first annular surface 68 and the second annular surface to prevent fluid leakage from the expandable chamber 38. . (3) The fixing device according to claim 2, wherein the connecting member 24.64 is arranged radially outward of the expandable chamber 38. (4) The fixing device according to claim 3, wherein the first annular surface 68 is radially outward of the second annular surface. -(5) The force generating means includes the expandable chamber 3
8 radially outwardly of the outer member 22 and the wheel 12 to define a shim insertion space between the outer member 22 and the wheel 12; , the retaining means 28.76 includes a shim 28 fixed within the shim space in contact with the outer member 22 and the opposing surfaces of the wheel 12 to maintain the compressive force exerted on the wheel 12. A fixing device according to claim 1. (6) The fixing device according to claim 5, wherein a shim cover plate 30 covers the shim and is fixed to the outer member 22 in order to hold the shim in the shim insertion space. (7) The fixing device according to claim 6, wherein the connecting member is a bolt 24, and the other end of the bolt is brought into contact with the front surface of the outer member 22. (8) the retaining means is threaded onto the connecting member 24.64 between the outer member 22 and the wheel 12 to maintain the tensile force exerted on the connecting member 24 and the compressive force exerted on the wheel 12; The fixing device according to claim 1, which includes a nut 76 adapted to engage the wheel 12. (9) The front connecting member is a stud 64, the other end 65 of the stud protrudes axially forward of the outer member 22, an outer nut 74 is screwed onto the other end 65 of each stud 64, and the outer nut 74 is screwed onto the other end 65 of each stud 64. 22. The fixing device according to claim 8, which is in contact with the front surface of the utility model.
