Pushing on the power output elements
● Prerequisites:
– The coupling and/or the output element must be appropriately dimensioned for the
operating case at hand.
– 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.
● Pulling on:
– 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 output element must be pulled on in one continuous operation via the front thread
holes in the shaft or pulled on by hand.
– Do not strike it with a hammer, as this would damage the bearings.
Shaft extensions with feather key
To maintain the balancing quality, you have the following options:
● If the output element is shorter than the feather key for balancing type "H": Machine off the
section of feather key protruding from the shaft contour and output element in order to
maintain the balance quality.
● If the output element is mounted up to the shaft shoulder for motors with full-key balancing
"F", or if the output element is longer than the motor shaft extension: When balancing the
coupling or the belt pulley, take into account that the feather key does not take up all of the
hub groove.
WARNING
The feather key can fall out
The feather keys are only locked against falling out during shipping. If a machine with two
shaft extensions does not have an output element on one shaft extension, the feather key
can fall out during operation.
Death or serious injury can result.
● Do not operate the machine unless the transmission elements have been pulled on.
● On shaft extensions without output element, take suitable measures to ensure that the
feather key cannot be flung out. For balancing type "H", shorten the feather key by about
half.
