Pulling on drive output elements
• Requirements:
– The coupling and/or the drive output element must be appropriately dimensioned for the
operating case at hand.
– Observe the coupling manufacturer's instructions.
– Make sure that the balancing type of the drive output element correctly matches the type
of balance of the rotor.
– Use only ready drilled and balanced drive output elements. Check the hole diameters and
the balancing status before pulling them on. Thoroughly clean the shaft extension.
• Pulling on:
– Heat up the drive output elements to expand them before pulling them on. Select the
temperature dierence for the heating process to suit the coupling diameter, t and
material. Observe the coupling manufacturer's instructions.
– Drive output elements may only be pulled on or pulled o with the correct equipment.
The drive output element must be pulled on in one continuous operation via the front
thread holes in the shaft or pushed on by hand.
– Do not use a hammer, as this will damage the bearings.
