Abstract: Aiming at the design of the rotor outputend and coupling for the steam turbine, the features of rotor for industrial steam turbine and design concepts of buildingblock were introduced. The design method of the rotor outputend and process were discussed. The development history of coupling design was reviewed. The type, regulations and requirements of coupling in current international standards were presented. The matching, configuration and design of rotor outputend and coupling were expatiated. The design developing direction in this area was pointed out. It was put forward that determining the nominal diameter of outputend, which was calculated using safe coefficient method of equivalent torsional stress, firstly in engineering design. The reasonable design in technique structure of thread form for the rotor outputend as well as the design of the location of oil groove were analyzed and discussed.
Key words: outputend of rotor; coupling; standard; fits; configuration; analysis; discussion
