ALIGNMENT ADJUSTING METHOD IN ROTARY SHAFT SYSTEM AND ALIGNMENT MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To enable a bearing height alignment adjustment to be carried out without separating a coupling connection between a driving shaft and a driven shaft by an easy less-expensive machine material.;SOLUTION: This invention comprises a bearing height difference size calculation step S1 for calculating a bearing height difference size applied in advance to each of the bearings when a rotary shaft system is kept cool; a dummy shaft mounting step S6 for mounting the dummy shaft imitating an assembly shaft on a bearing; descending amount measuring steps S7, S8 for depressing the dummy shaft by a depressing means from above of each of the bearings and measuring a dummy shaft descending amount until the dummy shaft is contacted with the bearing; a descending amount determination step S9 for determining whether or not the dummy shaft descending amount is within an allowable range of a specified descending amount led out of the bearing height difference size; and a height alignment adjustment step S5 for adjusting heights of a plurality of bearings when the determination result of the descending amount determination step S9 is a denial determination.;COPYRIGHT: (C)2015,JPO&INPIT
