Pushing on the power output elements
● Requirements:
– The coupling and/or the output element must be appropriately dimensioned for the
operating case at hand.
Carefully 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. Carefully comply with 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.
Shaft extensions with feather key
To maintain the balancing quality, you have the following options:
● If the transmission element is shorter than the feather key with balancing type "H", then you
must machine off the section of feather key protruding from the shaft contour and
transmission element in order to maintain the balance quality.
● If the transmission element is drawn up on to the shoulder of the shaft, you must ensure that
the part of the coupling groove where the feather key is not inserted is taken into
consideration when balancing the coupling.
The following applies to all four-pole machines with a frequency ≥ 60 Hz:
● The feather key must be shortened if the coupling hub us shorter than the feather key.
● The center of gravity of the coupling half should be within the length of the shaft end.
● The coupling used must be prepared for system balancing.
The number of poles of the machine is specified on the rating plate, at the 10th position of
the motor type. There, four-pole machines are marked with a "B".
Danger when feather keys are flung out
The feather key is only secured to prevent it falling out during transport. The feather key may
be flung out if the motor is operated without fitted transmission elements, such as coupling, etc.
This can result in death, serious injury or material damage.
● Only operate the motor with the transmission element pulled on.
● For test operation or when commissioning without transmission element, carefully secure
the feather key using a suitable locking element. When doing this, take into account the type
of machine balancing.
