Feb 15, 2014· Faults detection in planet gears of planetary gearboxes by vibration analysis is not as straightforward as the detection of failures in conventional gear transmissions This is because the driving flanks are different between the inner contact (ring–planet gear) and the external contact (sun–planet gear) Furthermore, the failure position varies with respect to the fixed transducer located .
May 01, 2021· Also, the vibration information of each component is redundant Since the sensor is close to the ring gear, it is reasonable to select the vibration of the ring gear to study the vibration mechanism of the gearbox (2) The bolt constraint of the ring gear is introduced in this paper, and the ring gear is simplified as the Euler Bernoulli beam
Calculators This program allows you to calculate bearing defect frequencies and then view them in a spectrum Simply enter the number of balls, ball diameter, pitch diameter and contact angle and press “calculate” The bearing defect frequency calculator will then give you options for which defect frequencies to display in the spectrum
