Abstract

PURPOSE: To absorb deformation stress due to the mounting of a rotor by means of pins or keys provided on a circle and reduce the change in the clearance between a main shaft and a guide bearing, by couping an upper disc and a support frame to each other by the pins or keys.
CONSTITUTION: A thrust bearing is provided on the bottom of the main shaft 1 and supported on the body 4 of a bracket 3. The guide bearing 12 is provided around the main shaft 1. The tips of adjusting bolts 11 are set in contact with the guide bearing 12. The adjusting bolts 11 are fitted in the rising part of the support frame 8 so that the bolts can be moved back and forth. The support frame 8 and the upper disc 5 are clamped on each other by bolts 10. A plurality of pins or keys 13 are provided on the contact surfaces of the frame 8 and the disc 5. When the rotor is mounted on the main shaft 1, the deformation stress is absorbed by the pins or keys 13. Therefore, the clearance g between the main shaft 1 and the guide bearing 12 can be reduced.
