Balancing, drive elements and vibration
The shaft and bearing must not be exposed to knocks.
No axial forces are permitted when mounting or dismounting the output elements.
The generally required measures to prevent contact with the output elements must be
observed.
If the motor is commissioned without the output element, the featherkey must be
secured to ensure that it is not thrown out.
Balancing:
With the standard version, the rotors are dynamically balanced as per EN 60034-14
ISO 8821 / ISO 1940 using a half key; does not apply for thrust-bearing motors.
NOTE:
Observe the type of balancing as identified on the shaft end face:
H = Balancing with half key
Standard version
F = Balancing with full key
Special version
Output elements:
When mounting the output element, note the appropriate type of balancing. The output elements
must themselves be balanced in accordance with ISO 1940.
Suitable jigs are always to be used for fitting or removing output elements (e.g. clutch disk, gear,
pulley).
•
Use the threaded hole in the end of the shaft.
•
When pulling, use intermediate washers to provide the shaft with mechanical protection.
•
Warm up output elements if necessary before mounting (max. admissible transient
temperature at shaft end 150 °C).
Attention:
•
On shaft versions without a key, the output elements are to be fastened to the output shaft
with the aid of suitable clamping sets
.
•
On shaft versions with a key, it must be ensured that
the output elements rest on the shaft
shoulder
. Note: The chamfer or radius on the output element and the shaft radius on the
shoulder (in accordance with DIN 748) must be matched.
•
Is the tapped hole in the end of the shaft used for axial securing of output elements (e.g. belt
pulley), the maximum tightening torque acc. to following table 3 must not be exceeded.
