Measurement method of bearing clearance: (1) false axis method Practical journal diameter and bearing A. false axis is within 0.05mm, the center line of false shaft and level the Perpendicularity Error of less than 0.02mm. B. bearing combination in false shaft, bolts tightening, with the 0.02mm check with feeler gauge middle surface gapless. Under the C. frame dial gauge and carried along the vertical direction when working on radial bearings, dial indicator reading is assumed to be S (mm), considering the effect of tilting pad bearing clearance around, the actual C (mm), of five tile structure: C=0.894S In addition, also need to be taken into the actual difference false shaft and shaft neck. (2) carried tile method Calculation method and the method of measuring the clearance of the lift tile method and false axis method is the same, but the rotors should be hanging out, supported by the bracket bearing can move and lift. (3) pressure wire method The A. wire diameter should be better than the measured gap 30-50%. B. on the plane surface bearing housing and bearing seat, with 0.02mm check with feeler gauge, middle surface should be seamless and good mouth. C. measuring lead wire thickness of two tile tile middle S, bearing clearance C actually is: C=1.1S
