GEAR FOR VIBRATION-ACOUSTIC DIAGNOSTICS OF TRANSMISSIONS BY ENGAGEMENT Russian patent published in 2004 - IPC

FIELD: parts of machines, vibration-acoustic diagnostics of transmissions in machines used in mechanical engineering, metal-working, machine-building, aviation and some more industries by engagement. SUBSTANCE: gear for vibration-acoustic diagnostics of transmissions by engagement includes at least one channel for isolation of measurement information containing path of test of vibration-acoustic signal and path of test of rotational speed, programmable computer, indicator and recorder which corresponding inputs are coupled to outputs of programmable computer. Channel of isolation of measurement information is added with path forming electric signal incorporating digital-to-analog converter coupled to programmable computer, program-controlled resonance circuit coupled to digital- to- analog converter and controller, adjustable amplifier coupled to digital-to- analog converter and path of test of vibration-acoustic signal. EFFECT: widened potential of analysis of time realization of processes of vibration recorded with simultaneous diagnostic information reading, increased efficiency of diagnostics of transmissions by engagement. 3 dwg
