IPC: G01H5/00
Filed: 2003-02-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide an ultrasonic propagation velocity measuring method for correctly measuring the propagation velocity of an ultrasonic wave even if measuring conditions including ultrasonic propagation time in a transmission sensor and a receiving sensor, and a solid surface fatigue measuring method using the above method.  <P>SOLUTION: The ultrasonic propagation velocity measuring method comprises the steps of measuring propagation times t1 and t2 twice with different propagation distances and calculating the velocity V at which the ultrasonic wave propagates on a raceway plane 10A of an inner ring 10. Therefore, characteristics (film thickness, viscosity, etc.) of a contact medium interposed between the transmission and the receiving sensors 1 and 2 and the raceway plane 10A and variation of the propagation time caused by the roughness of the raceway plane 10A offset each other. Further, propagation times tpx1 and tpx2 in the transmission probe 22 in the two measurements and propagation times tpy1 and tpy2 in the receiving probe 32 are subtracted from the propagation times t1 and t2 by the two measurements.  <P>COPYRIGHT: (C)2004,JPO
