摘要：

为深入了解同功重比修形斜齿与直齿面齿轮的性能差异，选择更适合于高速重载工况下的面齿轮传动.基于啮合原理推导了修形斜齿与直齿面齿轮齿面方程，基于CATIA建立了修形斜齿与直齿面齿轮三维模型，采用有限元接触分析方法，以接触应力、弯曲应力和重合度为面齿轮传动性能指标展开研究.研究结果表明：修形斜齿面齿轮相比修形直齿面齿轮接触应力大幅降低，算例最大接触应力降低16.3%；修形斜齿面齿轮相比修形直齿面齿轮弯曲应力大幅降低，算例最大弯曲应力降低32.4%；修形斜齿面齿轮相比修形直齿面齿轮重合度大幅提高，算例重合度提高10.3%.所以同功重比情况下，修形斜齿面齿轮传动性能优于修形直齿面齿轮，前者更适合于高速重载工况下的轻量化设计.

Abstract:

In order to know the performance difference of the modified face gears with helical pinion and spur pinion under the same power density better and choose a more suitable kind of face gear drive for high speed and heavy load conditions. Based on meshing theory, the tooth surface equations of the modified face gears with helical pinion and spur pinion were derived. The three-dimensional models of the modified face gears with helical pinion and spur pinion were built by CATIA. The finite element contact analysis method was used and the contact stress, bending stress and contact ratio were considered as performance indexes of the face gears to expand the research. Researches proved that the contact stress of modified face gear with helical pinion was much lower than that of modified face gear with spur pinion. The maximum contact stress was reduced by 16.3% in the case. The bending stress of modified face gear with helical pinion was much lower than that of modified face gear with spur pinion. The maximum bending stress was reduced by 32.4% in the case. The contact ratio of modified face gear with helical pinion was much higher than that of modified face gear with spur pinion. The contact ratio was increased by 10.3% in the case. So the transmission performance of the modified face gear with helical pinion is better than that of modified face gear with spur pinion under the same power density, the former is more suitable for the lightweight design under high speed and heavy load condition.
Key words: lightweight    power density    contact stress    bending stress    contact ratio    modification
