Smooth running
Preconditions for smooth, vibration-free operation according to DIN 4024 include:
–
Stable foundation design free of any shock or vibration.
–
A precisely aligned coupling.
–
A well-balanced drive output element (coupling, belt pulleys, fans, ...)
Maintain the maximum permissible vibration in operation according to ISO 10816.
Avoid inadmissible vibration caused by imbalance, for example (drive output element),
external vibration or any resonance over the complete speed range.
It may be necessary to completely balance the machine with the drive output element or
the system resonance frequency must be shifted.
●
Foot mounting/flange mounting
–
Use the specified thread sizes laid down in EN 50347 when flanging the machine to a
foundation or a machine flange.
–
Mount the machine at four foot or flanged holes that are at right angles to one another.
The customer is responsible for selecting the strength (property class) of the mounting
elements.
For mounting elements up to and including frame size 160, property class 5.6 or
higher is recommended, from frame size 180, property class 8.8 or higher.
–
Select the correct screw length for IM B14 flanges.
●
IM B30 pad mounting (duct fans or fans installed in pipes)
To install the motor in the equipment, use all DE and NDE mounting brackets or all 8
bores in the enclosure.
Use suitable locking measures to prevent the connections from being released in normal
operation and operation under fault/fire conditions.
Observe the maximum tensile force and compressive force for each mounting bracket.
