摘要： A rotor (1) of a gas turbine compressor comprises a multiplicity of welded-together rotor disks (3a, 3b, 4, 5), of which two or more rotor disks (3a, 3b), in a radially outer region (9′), are welded together, and, in a radially inner central region (9), are abutment-joined together. Via the abutment-joining of two rotor disks (3a, 3b), a heat flow (8) radially outward from the center of the rotor (1) is achieved so that the material temperature of the rotor (1) can be kept below a predetermined level during operation. As a result, the service life of the rotor (1) can be increased. In one embodiment, one rotor disk (3a), on its surface, additionally has a recess (7) which can be cooled from outside. The rotor disks (3a, 3b) according to the invention, which are welded and abutment-joined together, can especially be used at the last point in the flow direction of the compressor.
摘要翻译：燃气涡轮压缩机的转子（1）包括多个焊接在一起的转子盘（3a，3b，4,5），其中两个或更多个转子盘（3a，3b）在径向外部区域（9' ）焊接在一起，并且在径向内部中心区域（9）中被邻接连接在一起。通过两个转子盘（3a，3b）的邻接连接，实现了从转子（1）的中心径向向外的热流（8），使得转子（1）的材料温度可以保持在低于操作期间预定水平。结果，可以提高转子（1）的使用寿命。在一个实施例中，一个转子盘（3a）在其表面上另外具有可从外部冷却的凹部（7）。根据本发明的转子盘（3a，3b）可以在压缩机的流动方向的最后点特别地被焊接和邻接连接在一起。
