Reliability Analysis of Spiral Bevel Gear Wear Based on Improved First Order Second Moment Method
The equivalent gear theory is used to simplify the meshing process of spiral bevel gears,and a wear model of spiral bevel gears is established based on the Archard model. The wear amount of each point on the midpoint normal section of the gear teeth is compared,and the dangerous points on the midpoint nor-mal section of the gear teeth are selected. The wear reliability analysis of the dangerous points is carried out,and the limit state function is established based on the advanced first-order second-moment method ( AFOSM),Based on MATLAB programming,the reliability and design points of spiral bevel gears under selected design parameters are obtained,and the influence of changes in working torque and working speed on their reliability is calculated. Monte Carlo method is used for reliability simulation analysis. The calculation results of the two methods are close,indicating that this method has high efficiency and accuracy. The above work provides certain reference and reference for the reliability design and maintenance of spiral bevel gears.
