Method for manufacturing variable speed accelerator and method for connecting shaft jig

A method for manufacturing a variable speed motor and a transmission device for a variable speed accelerator comprising:

• a preparation step of preparing a variable speed motor and a planetary gear transmission device,
• wherein the variable speed motor includes a variable speed rotor in which a hollow portion extending in a horizontal direction is formed, a variable speed bearing that rotatably supports the variable speed rotor by aligning an axial direction of the variable speed rotor in the horizontal direction, a variable speed stator that surrounds the variable speed rotor from an outer circumferential side with respect to the variable speed rotor, and a variable speed electric motor casing in which the variable speed stator is fixed therein, and the planetary gear transmission device that has an input side planetary gear carrier shaft connected to the variable speed rotor of a variable speed electric motor, wherein the input side planetary gear carrier shaft forms a cylindrical shape;
• and
• a shaft insertion step of inserting a constant speed shaft, which is configured to be rotatable independently with respect to the variable speed rotor and the input side planetary gear carrier shaft, into the hollow portion of the variable speed rotor and a through hole of the input side planetary gear carrier shaft in the horizontal direction so as to penetrate the variable speed rotor and the input side planetary gear carrier shaft, after the preparation step, wherein
• in the preparation step, the variable speed stator and the variable speed rotor are incorporated in advance in a state where an alignment adjustment is performed, and an alignment adjustment of an output side end of the variable speed rotor is performed by adjusting a height of the variable speed electric motor casing with the input side planetary gear carrier shaft as a reference, and
• the alignment adjustment is performed after a vertical positional deviation amount between the input side planetary gear carrier shaft and variable speed rotor shaft is measured by a measuring instrument.
