Shaft Alignment
Shaft Alignment
(OP)
I hope is ok to ask this question within this forum. My question is about shaft alignment. I know the ideal way would be to align both shafts with a laser device connected to both shafts. But would you still accomplish the same results if one device is fixed to the coupling of the fixed piece of equiptment and the other is on the shaft of the moveable equiptment. There is not enought room to place the fixture on the fixed shaft.
Thanks
Thanks

The exception is coupling sleeves, which are NOT attached to the shaft, as shown here - http:
Don't forget to consider thermal expansion, radial forces and (sleeve) bearing clearance (gearboxes with sleeve bearings).

In the above link the "sleeves" are attached to each other and have curvy gear teeth cut on the insides. Those gear teeth engage teeth cut on the outside of the hubs. The hubs are attached to the shafts. Like this.......

The hub>sleeve<hub connection has 1 power transmission plane at each hub, so the sleeves pivot to "connect the dots" between transmission planes. Kind of like this.

Anyhow, if the alignment laser heads (or dial indicators) are accidentally attached to the sleeves they will report perfect alignment since they are effectively attached to a hunk of pipe. "Alignment" is meant to determine the concentiricty of the two shafts
