Detecting critical rotary vibrations, esp. in engine drive trains - using transducer elastically coupled to drive train with resonant frequency in region of critical vibration

The arrangement for detecting critical rotary vibrations contains a revolution rate meter with a transducer (1) driven proportionally w.r.t. an angular speed. The transducer is elastically coupled to a drive and its resonant frequency lies in the region of the critical rotary vibraton. The resonant...

Beschreibung
Zusammenfassung:	The arrangement for detecting critical rotary vibrations contains a revolution rate meter with a transducer (1) driven proportionally w.r.t. an angular speed. The transducer is elastically coupled to a drive and its resonant frequency lies in the region of the critical rotary vibraton. The resonant frequency is variable by connecting several wts. and/or springs (4) in series and/or parallel. Several transducers with different natural frequencies can be coupled together. ADVANTAGE - Produces sufficiently large signal output as result of torsional vibrations.
