Abstract
On this research, the effects of the three different types of blade sections including linear, circular and polynomial on mesh characteristics for face-hobbed hypoid gears are investigated. Firstly, with the equations of three blade sections and the transformation matrixes based on the processing method derived, the mathematical model of gear flank and loaded finite element mesh model are proposed. Then, the impacts of different blade sections on tooth surface deviation and mesh characteristics are analyzed. Results show that the effects are almost identical when the parameters choose reasonable for the three blades. However, with the circular radius reducing, the peak-to-peak value of transmission error decreases but the contact pattern area shrinks and the location of maximum bending stress will change. For the polynomial blade, the effects the design parameters on mesh characteristics are obvious.
