Hi everyone, We have a couple of steam turbines in our plant that are used to run multi-stage compressors. Now there are gear/spline couplings between each barrel of a compressor. My question is that what is the purpose of having large coupling floats of around 15 mm or more when the axial float of a barrel's shaft could be max 0.8 mm due to its thrust bearing. Is there a reason behind having such large coupling floats??
Thanks in advance!!
