摘要: This invention relates to apparatus for the detection of accustic impact frequencies, characteristic bearing assembly failure during operation, which modulate an acoustic carrier frequency band. allows on-site or field application with high-level ambient noise such as are present in railroad yards. early failures, so that a repair may be made before damaging heat build-up catastrophic occurs. Additionally, sufficient warning applications, train continue running railyard convenient shop rather than expensive repair.
