Journal ArticleDOI
Finite element method model to predict bulk and flash temperatures on polymer gears
Carlos M.C.G. Fernandes,Diogo M. P. Rocha,Ramiro C. Martins,Luis Magalhaes,Jorge H.O. Seabra +4 more
TL;DR: In this article, a FEM thermal model was implemented to predict the bulk and flash temperature of gears in general and polymer gears in particular, and a solution for the temperature rise and distribution along the tooth is suggested.
Journal ArticleDOI
Influence of tooth profile and oil formulation on gear power loss
TL;DR: In this paper, the power losses reduction is obtained using two different approaches: using lower modulus helical gears and significant positive profiles shifts and using gear oil formulations with different base oils.
Journal ArticleDOI
Austempered ductile iron (ADI) gears : Power loss, pitting and micropitting
TL;DR: In this paper, a systematic experimental evaluation of austempered ductile iron (ADI) as a gear material was performed on the FZG test rig and the results showed that ADI is a material to be considered by gear designers, once the energetic behavior of ADI gears is similar to carburizing gears.
Journal ArticleDOI
Experimental observations of contact fatigue crack mechanisms for austempered ductile iron (ADI) discs
TL;DR: In this paper, images concerning crack development at ADI surfaces and sub-surfaces are presented, collected from several twin-disc contact fatigue tests, and several auxiliary surface analysis techniques are used (electronic scanning microscopy, video imaging and perfilometry).
Journal ArticleDOI
Low-loss austempered ductile iron gears: Experimental evaluation comparing materials and lubricants
TL;DR: In this article, three low-loss gear models were manufactured using standard 20° pressure angle tools and tested in an FZG gear test machine using mineral, ester and polyalphaolephine (PAO)-based oils.
