Title:
CENTERING DEVICE FOR ROTARY MACHINE
Document Type and Number:
Japanese Patent JPS5921255
Kind Code:
A
Abstract:
PURPOSE:To precisely perform a centering of a rotary machine by refracting a laser light projected from a laser length measuring unit perpendicularly by a reflector provided substantially at the center of the circular hole of a rotor, reflecting it on the inner peripheral surface of the rotor and again refracting it on the reflector to measure the length. CONSTITUTION:A laser beam 7 from a laser length measuring unit 6 is emitted to a refractor 8 held at 3 substantially at the left side of the circular hole 2 of 1a rotor 1 to perpendicularly refract the beam, reflected on a reflector 9 provided on the inner surface of the rotor, and again refracted at 8 to the unit 6 which measures the length. Then, the reflector 9 is rotated at 180 deg. to similarly measure the length by a reflector 91, the hole 3a of the holder 3i is elevationally moved so that the difference between both becomes 0 to install the refractor 8 elevationally at the center. Similar operation is performed laterally to obtain the center. Then, the center obtained at the left side is similarly performed through the laser light for the right side of the circular hole 2, not shown. In this manner, precise centering can be performed with good workability.
