Abstract

Highlight: The effects of work holding equipment errors on geometry and mesh were investigated. The face-hobbed hypoid gear model considering eccentricities was established. The correspondence between transmission error and gear geometry was established. The method of separating long wave and short wave of transmission error was proposed. The geometry and mesh are more sensitive to angular eccentricity. Abstract: This paper proposed the accurate mathematical model considering work holding equipment errors based on the three-face cutter differing from typical commercial software. The simulated flow included manufacturing issues from industry applications have been established. Quasi-static loaded tooth contact analysis was used to discuss the contact characteristic and gear geometry with existence of radial and angular eccentric errors. In addition, the correspondence between transmission error and gear geometry was established. The method of separating the long wave (low frequency) and short wave (high frequency) from total transmission error has been proposed. Results show that the effect of angular eccentric error on gear geometry is more sensitive than that of radial eccentric error. The gear geometry deviations present periodic changes because of variation of pitch error. And radial eccentric error cannot influence the position and shape of contact pattern. On the contrary, with existence of angular eccentric error, the contact area moves to the heel side and then backward. Furthermore, the length of contact pattern is firstly decreased and then increased in one period. The transmission error is sensitivity for both two eccentric errors and the peak to peak value of transmission error increase obviously.
