The research of the load-capability of the asymmetrical plastic spur gears

Abstract

The asymmetry gear has a high pressure angle to the operation tooth surface. Hertzian stress and the flash temperature of the asymmetry gear are small. Therefore, the load-capability can be increased without changing the gear size and the material of the gear. The steel asymmetry gear is already practicalized. As for the plastic gear tooth, the bending strength is more dominant than the tooth surface strength. In this research, it is confirmed by the analysis and the experiment about the load-capability of the asymmetry plastic spur gears.
