On Dynamic Loads in Parallel Shaft Transmissions. 2. Parameter Study.

Abstract

Solutions to the governing equations of a spur gear transmission model, developed in NASA TM-100180 (AVSCOM TM-87-C-2) are presented. Factors affecting the dynamic load are identified. It is found that the dynamic load increases with operating speed up to a system natural frequency. At operating speeds beyond the natural frequency the dynamic load decreases dramatically. Also, it is found that the transmitted load and shaft inertia have little effect upon the total dynamic load. Damping and friction decrease the dynamic load. Finally, tooth stiffness has a significant effect upon dynamic loading: the higher the stiffness, the lower the dynamic loading. Also, the higher the stiffness the higher the rotating speed required for peak dynamic response.
