Balancing type on the drive-end side
– The coupling and/or the output element must be appropriately dimensioned for the
operating case at hand. The balance quality must satisfy the following requirements.
– Comply with the coupling manufacturer's instructions.
– Make sure that the balancing type of the transmission element correctly matches the
type of balance of the rotor.
– Use only ready drilled and balanced transmission elements. Check the hole diameters
and the balancing status before pulling them on. Thoroughly clean the shaft extension.
– Warm up the transmission elements to expand them before pulling them on. Select the
temperature difference for the heating process to suit the coupling diameter, fit and
material. See the coupling manufacturer's instructions.
– Power output elements may only be pushed on or pulled off with the correct equipment.
The transmission element must be pulled on in one continuous operation via the front
thread holes in the shaft or pushed on by hand.
– Do not strike it with a hammer, as this would damage the bearings.
