| Abstract:To study the gear drive of a diesel engine, the specialized analyzing software for gear named ROMAX is used to carry out research on the contact and flexural fatigue strength of all gears, thus obtained the reliability distribution condition of the whole gear mechanism. The contrast analysis on the reliability of two design programs show that the new program features high reliability and more uniform strength distribution, and its components' structure design are closer to life design target. |
