Research on bending strength of face-gear transmission based on contact finite element method

The fillet surface equation of face gears was presented when the top of the shaper tooth was rounded. A 'mesh filter method' was proposed in view of the particularity of face-gear's structure, and the distortion of the element shape was corrected. Based on tooth contact analysis (TCA), the variation of bending stresses during the cycle of meshing was computed with 3-D contact finite element method when some parameters changed. The results indicate that both of the nominal pressure angle and shaft adjustments of face-gear have significant influence on the bending strength.
