The oscillation speed must be determined at the following measuring points
▪
on the motor side
– vertically (fan guard/auxiliary ventilator screw connection - A)
– horizontally (fan guard/auxiliary ventilator screw connection - B)
▪
on the compressor part
– vertically (compressor cover - C)
– horizontally (compressor cover - D)
– axially (compressor cover - E)
Accelerations
Maximum permissible acceleration for the constructed machine
0.3 x g
NOTICE! The rolling bearings can be destroyed by excessive alternating
stresses.
