Abstract
A small and high-strength spiral bevel gearfabricated using a five-axis controlled machining center hasbeen developed. In previous paper, we proposed a novel spiralbevel gear with ribs at the end of the tooth width to reinforce thetooth bending strength, which is machined with a ball-noseend-mill tool. However, it was shown that the stress could beconcentrated around the ribs depending on the shape althoughthe tooth root stress was reduced. Therefore, in this paper, weinvestigated the influence of the rib shape and size on themaximum stress at the tooth and rib root fillet and the toothdeflection with FEM analysis. The results revealed a novelguideline for designing the shape and size of rib at the end of theteeth width for the small and high-strength spiral bevel gear.
