摘要：
In order to improve meshing performance of drive bridge hypoid gears, a kind of Ease-off topology modification method was proposed for hypoid gears with HFT method. On the basis of establishing conjugate mesh mathematical model, the pinion base tooth flank equation was derived by means of calculating the deviations between the pinion actual tooth flank and pinion base tooth flank, and the Ease-off topology was constructed. The Ease-off topology was decomposed by means of second-order surface approximation, and the tooth flank mismatch factors were calculated, and the modified Ease-off topology was established after correcting mismatch factors. After comparing the current Ease-off topology and the modified Ease-off topology and correcting the deviations between the pinion current flank and the pinion modified flank, the pinion correction processing parameters were obtained. Finally, taking a pair of hypoid gear for example, the flank topology modification and grinding experiments were executed, and the validity of tooth flank topology modification was verified because of the real contact pattern coinciding with the meshing simulation results. The load tooth contact analysis results indicate that the modified tooth flank contact stress distribution is improved and the actual tooth contact ratios under loads are increased, so the validity of modification project is verified. © 2019, China Mechanical Engineering Magazine Office.
