In this paper, a space-driven two-stage spur gear system is taken as the research object, and 10 DOF dynamic model established. Considering high load characteristics of space drive time-varying stiffness tooth clearance system, nonlinear response analysis was performed. The vibration acceleration, shock transmission error are studied in paper. This paper analyzes relationship between backlash r...

The International Organization for Standardization (ISO) provides a method by which different spur and helical gear designs can be compared in terms of the risk for surface fatigue. The calculation of surface durability is based on Hertzian contact theory modified by factors for making adjustments peculiar to gearing. These factors are mainly determined through experimentation, and include surf...
