HOISTING MACHINE FOR ELEVATOR AND METHOD OF ADJUSTING HOISTING MACHINE FOR ELEVATOR

摘要

PROBLEM TO BE SOLVED: To simplify a work for adjusting the eccentricity of a rotating body of a hoisting machine and reduce the number of components.;SOLUTION: A hoisting machine 1 includes: a rotating body 5 comprising a sheave 2 and a disk 4 that are juxtaposed to lift/lower a cage and rotate together due to rotating force of a shaft 3; detection means 8a, 8b for detecting the state of eccentricity between the rotating body 5 and the shaft 3; adjustment means 7 for adjusting the position of the disk 4 relative to the sheave 2 to an appropriate eccentric position on the basis of detection results from the detection means 8a, 8b; and fixing means 6 for fixing the sheave 2 and the disk 4 after the position of the disk 4 is adjusted.;COPYRIGHT: (C)2015,JPO&INPIT
