Vibration types for Machine, Rolling Bearing and Geardiagnosis

Machine part vibration – Shaft vibration	Machine vibration	Body sound - Ultra sonic
displacement	velocity vibration severity	Body sound
visible	tactil	hearable in air sound or on housing with stethoskop
Vibration displacement	Vibration velocity	Acceleration (Jirk - 1. differantiation) (Jump - 2. differantiation)
s in µm	v in mm/s	a in m/s²
5 - 400 µm (0,1 - 10 m/s²)	1 - 20 mm/s	0,01 - 1000 m/s² (<<1 µm, x nm, x pm)
0,1 bis 400 Hz	1 / 2 / 10 Hz bis 1 / 3 kHz	1 / 3 kHz bis 40 kHz bis x*100 kHz
relative and absolute shaft vibration	vibration of housing	body sound
Sleeve bearing-rotor-system	Machines and machinesets with rolling bearings	rolling bearing teeth gear – gear mesh tool machines - metal cutting manufacturing machine
Two channel measurement in orbit under 90 degree in main axis or under 45 degree	Measurement in three main axis Vibration depends from direction	Measurement in load zone of bearing, aligned to load zone
Distance sensors Displacement transducer	Velocity transducer Accelerometer	Accelerometer
