Abstract
The utility model discloses a centering coupler of a steam turbine rotor, and the centering coupler is provided with a steam turbine rotor coupling piece and a generator rotor coupling piece which are connected by two bolts; and when a steam turbine unit overhaul rotor is centered, the bolts connect the steam turbine rotor with a generator rotor into a whole to rotate together. According to the centering coupler of the steam turbine rotor, the centering precision of the rotor and the working efficiency can be improved.
Description
Technical field
The utility model relates to coupling, directly relates to turbine rotor alignment coupling.
Background technology
During the alignment of flexible connection turbine rotor, need rotate turbine rotor and generator amature respectively, accuracy is poor, and is bigger for the alignment error ratio.
Summary of the invention
The purpose of the utility model will provide a kind of turbine rotor alignment coupling exactly, and there is the problem of error in it in the time of solving the turbine rotor alignment effectively.
The utility model is achieved in that to have two bolted turbine rotor connectors and generator amature connector, and when the alignment of Steam Turbine maintenance rotor, bolt connects as one co-rotation with turbine rotor, generator amature.
The utility model can connect as one co-rotation with two rotors owing to be provided with bolt and connector, has reduced the difficulty of alignment work.
Description of drawingsAccompanying drawing shows the structural representation of the utility model turbine rotor alignment coupling, and the knot accompanying drawing is described further the utility model below.
The specific embodimentAccompanying drawing shows the structure of the utility model; Have turbine rotor connector 1 and generator amature connector 2 that two bolts 3 connect; It is characterized in that: when the alignment of Steam Turbine maintenance rotor, bolt 3 connects as one co-rotation with turbine rotor, generator amature.The utility model can improve the precision of rotor alignment, increases work efficiency.
