SENSOR FOR DIAGNOSTICS OF ROLLING FRICTION PARTS Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: electric signal of vibrators 1 mounted on rolling friction parts is passed through self-normalizing unit 4, high-frequency filter 5, amplitude-frequency response unit 6, peak detector 7, signal extremum data recording unit 12, average absolute value detector 13, low-frequency filter 14 and, arrives via second switch 8, analog-to-digital converter unit 9, and input/output unit 10 to microprocessor processing unit 11. The latter indicates and translates digital data on degree of fracture, distribution of lubricant thickness in defective region and on bearing member where flaws are detected to display unit 15 and computer network. Electric signal of vibrators 1 also goes through signal level detector 20, 21, second-low-frequency filter 22. EFFECT: provision for self-inspection of device. 3 cl, 1 dwg
