Stresses Analysis of Hypocycloidal Gear Transmissions

Abstract

The objective of this research is to enhance the performance of a Hypocycloidal Gear Transmission (HGT) by selecting the favorable gear profile which has the most significant effects on performance. The research presents computer-aided design and analysis of the HGT. Careful design of the curtate-cycloid tooth profile can further enhance the performance of the HGT by dramatically improving the Hertz contact property. This high contact ratio leads to ideal load distribution. In the loaded tooth contact analysis, the real contact ratio under the tooth deformation was analyzed for demonstration of an effective self-protecting feature, which makes the HGT suitable for extremely heavy load applications. This paper successfully proves that the HGT is a promising architecture for the high reduction ratio reducers. The design and analysis of these prototype HGTs have been fully addressed here.
