Generation of a crowned pinion tooth surface by a surface of revolution [PDF]

open access: yes
A method of generating crowned pinion tooth surfaces using a surface of revolution is developed. The crowned pinion meshes with a regular involute gear and has a prescribed parabolic type of transmission errors when the gears operate in the aligned mode.

A method of selecting grid size to account for Hertz deformation in finite element analysis of spur gears [PDF]

open access: yes
A method of selecting grid size for the finite element analysis of gear tooth deflection is presented. The method is based on a finite element study of two cylinders in line contact, where the criterion for establishing element size was that there be ...
