i am a little confused in tilting pad journal bearing curves.
i know concept of preload and design factors in pads curve in Babbitt side (shaft side actually) but what is radius of back of pads? (in attached file is named R out)
as we know in pivot type, back of pads contact with bearing shell (named R bearing) and i think if R out = R bearing it dose not happened any tilt. so i guess R out must be different with R Bearing. is my logic true? and how can obtain R out?
if we assumed it is true, so thickness of pad should not be same in all along of pad.
