Finite element modelling and analysis of a straight bevel gear tooth

Finite element modelling and the analysis of a straight bevel gear tooth is carried out to evaluate the bending stresses. An isoparametric brick element is used for finite element analysis. The stress distribution obtained at the root of the tooth is compared with the experimental results available in the literature and the tooth behaviour at the root is studied by changing the various parameters such as torque, pressure angle, shaft angle, rim thickness and face width of the gear pair. This paper also discusses the load distribution on the face of the tooth as well as the variation of load in magnitude and position as the tooth rotates. © 1993.
