If you guys can make a video on the shaft play according to the bearings like if there is case where the Multistage charge pump having Babbit/Journal bearing along with deep groove ball bearing at DE side and on opposite they have Angular Contact ball bearings with an arrangement to compensate the axial thrust, In that case if the shaft dia is more resulting more play of shaft with bearings, when to use two plunger dial indicators on face of Coupling hub with one on top/rim and when to use single gauge on face with one on rim on the coupling hub(Generally they say when there is shaft play>+_0.05mm it would be correct to use two dial indicators placed at 180° on face of hub) In short is there any specific criteria for using two gauges on face while rim and face alignment, Its quite interesting to understand these things but it gives sometimes headache😅
Can you guys just tell me it's quite confusing to understand why two plunger dial indicators used on FACE in rim and face alignment in condition where it seems to be high rotor play(maybe > 0.05mm shaft play), I mean I don't get a point where some people do just A1-A2 and some do [A1+A2]/2, And if subtraction(A1-A2) why logically And if addition(A1+A2) why logically I have a little confusion about above mentioned things only and it would be helpful for me to understand more correctly if you approach here to answer.
Have any shaft alignment questions? If so, drop us a comment and we will try to help!
PLEASE TYPES OF COUPLING AND ALIGMENT
