| Abstract: | A model of time-variant reliability and its computation method of gear drive under multi-failure mode are presented.The time-variant model of gear strength is created by using the relationships curve between the gear fatigue lifecoefficient and the number of stress cycle.And then the reliability analysis model of gear drive is presented,in which the contact fatigue failure and blend fatigue failure are taken into account.The time-variant probabilistic formula of the contact fatigue failure and blend fatigue... |
