Warm assembly of coupling hub with conical seat
1.
Push the coupling hub carefully onto the shaft journal in cold condition in horizontal/central position, until it reaches the stop.
Mark the position of the coupling hub including the pull-on path on the shaft journal.
If required, ***make a device/stop*** to ensure that the coupling hub cannot be pulled over the mark when it is hot.
2.
Pull coupling hub off the shaft journal and heat it evenly in an oil bath or in an oven as per manufacturer’s instructions.
3.
Pull the heated coupling hub onto the shaft journal, until it reaches the mark/stop using corresponding protective/auxiliary equipment.
Prior to cooling down the coupling hub ensure that it is arranged at a right angle and centrally on the shaft journal.
