Analysis of Sensible Random Factors that Influence Gear Reliability
Based on the computation method of reliability in limit state theory, the paper analyzes sensitivity of gear reliability with the change of various random factors. Taking the reliability computation of circular gear as an example, it systematically calculates the change of gear reliability with the change of average value and RMS error of random variables. Based upon the computed result, it analyzes and finds out sensible random factors that have larger influence on gear reliability for the convenience of strict control of gear design, manufacturing, use and maintenance in future in order to guarantee the requirement for gear reliability. Computed result in this paper can be used as reference for the study on gear reliability in future.
