Temperature Influence on Real-Time Ultrasonic Detection of Multi-Planetary Gear Transmission

Abstract:

Key structure of multi-planetary gear transmission such as gear box body, planetary carrier should be monitored by non-destructive testing technology under work to ensure reliable operation. However, temperature of such components under operation is not normal, which will affect the detection result. Temperature influence upon ultrasonic on-line detection was researched. Such factors as ultrasonic propagation velocity, ultrasonic attenuation, ultrasonic probe emissive power and refraction angle of angle probe were analyzed. Multi-planetary gear transmission ultrasonic monitoring case has been completed.
