| 发明名称 | Axial flow compressor | ||
| 摘要 | An axial flow compressor includes: a rotor having a rotor vane; a first pressing member joined to one end surface of the rotor; a second pressing member joined to the other end surface of the rotor; a rotor shaft portion penetrating the first pressing member, the rotor and the second pressing member; and a nut which fixes the first pressing member and the second pressing member on the rotor shaft portion with the first pressing member and the second pressing member holding the rotor between. The rotor shaft portion is made of a material having a lower linear expansion coefficient than that of a material making at least a part of the rotor. The material making at least a part of the rotor may be aluminum or aluminum alloy. | ||

| 主权项 | 1. An axial flow compressor which compresses a working fluid, comprising: a rotor including a rotor vane; a first pressing member coming into contact with one end surface of the rotor; a second pressing member coming into contact with the other end surface of the rotor; a rotor shaft portion penetrating the first pressing member, the rotor and the second pressing member; and a fixing portion which fixes the first pressing member and the second pressing member on the rotor shaft portion with the first pressing member and the second pressing member holding the rotor between, wherein the rotor shaft portion is made of a material having a lower linear expansion coefficient than that of a material making at least a part of the rotor. | ||
