Abstract
The present invention relates to a turbine engine comprising a wheel, (2) mounted on a shaft (4), and a disk (18), adjacent to the wheel (2) and mounted on the same shaft while being rotated by the latter. The disk (18) is made of a material having a density greater than that of the material used to manufacture the wheel (2). The invention is of use in a compressor/turbine.
Claims18
A turbomachine, comprising:
- a wheel (2) made from a first material having a first density and being mounted on a shaft (4) at a first point;
- and
- a disk (18) removably mounted to the shaft at a second point adjacent to said first point where said wheel is mounted to said shaft, said disk and said wheel being rotationally driven by said shaft, wherein said disk is made from a second material having a second density which is greater than the first density of the first material of the wheel and said second density is greater than 15 kg/dm3.
A turbomachine, comprising:
- a shaft (4);
- a stud (8) having a first end and a second threaded end, said first end being fixed to the shaft to laterally extend said shaft;
- a wheel (2) made from a first material having a first density and being mounted on said stud at a first point;
- a disk (18) removably mounted to the stud at a second point adjacent to said first point where said wheel is mounted to said stud, said disk and said wheel being rotationally driven by said shaft, wherein said disk is made from a second material having a second density which is greater than the first density of the first material of the wheel and said second density is greater than 15 kg/dm3, and
- a nut (14) screwed to the second threaded end of the stud to damp the disc and wheel to the shaft.
2 more elements
A compressor turbine, comprising at least one turbomachine, the at least one turbomachine comprising:
- a wheel made from a first material having a first density and being mounted on a shaft (4) at a first point;
- and
- a disk removably mounted to the shaft at a second point adjacent to said first point where said wheel is mounted to said shaft, said disk and said wheel being rotationally driven by said shaft, wherein said disk is made from a second material having a second density which is greater than the first density of the first material of the wheel and said second density is greater than 15 kg/dm3.
