【Abstract】 In this paper, in order to obtain the mixed and discrete optimum solution, a method of reliability-optimum design combining reli-ability calculation and optimum design is applied to the calcula-tion of gear strength.This method not only offers the optimum solution to the determination of gear strength but also to the failure probability in gear transmission and hence overcome the various kinds of drawbacks, semi-scientific and semi-experienced,in the conventional calculation of gear strength. Moreover, the author makes a detailed exposition of the prin-ciple, algorithm, flowsheet and mathematic model and checks them against typical examples and finally makes a contrast analysis be-tween the result obtained by this method and that by conventional strength calculation.更多还原
