Abstract
PURPOSE: To make it possible to detect abrasion in slide motion without disassembling a member which can not be seen by the eye, by detecting an abrasion state by detecting an ultrasonic wave generated by a sliding body.
CONSTITUTION: Adjusting time-difference measuring circuit 18 enables sensor 12, etc., to receive only an ultrasonic wave from part A of cell 1 opposing to abrasion detection part 11 parallel to cell 1 at a point corresponding to abrasion tolerance (h) of movable blade 2 sliding on cell 1 while rotating together with its axis. When blade 2 wears and detection part 11 comes in contact with cell 1, the ultrasonic wave generated by detection part 11 with noises mixed is detected by sensors 12 and 13 provided to cell 1 and an ultrasonic-wave detection signal with noises of more than a fixed threshold level through comparator circuit 17 removed is applied from sensors 12 and 13 to circuit 18. Pulses generated by circuit 18 olny on arrival of pulses with a prescribed time difference corresponding to width A of detection part 11 are counted by counter 19 and when the integral number exceeds a reference value, abrasion can be detected in slide motion without disassembling a member where it is impossible to see by the eye the abrasion reaching its tolerance.
