A new tooth profile gear, ＂S＂ tooth profile gear, was proposed herein. The mathemati- cal models, including the equation of tooth profile curve and equation of tooth surface, were estab- lished based on kinematical method of meshing theory. A finite element model was established and the finite element analysis in the condition of contact was finished by UnigraphicsNX, Hypermesh and ANSYS software. The results illustrate that ＂S＂ tooth profile gear have the advantages of bearing of greater loading force, etc.
