摘　　要：在纵置变速器中,常啮合齿轮副可靠性的高低对于变速器整体性能水平有很大的影响。针对某汽车纵置变速器常啮合齿轮失效故障进行分析,根据分析结果,运用RomaxDesigner软件中的齿面微观几何分析技术对该齿轮副进行优化设计。对齿轮副进行齿面微观优化修形,并对优化修形前后齿面载荷分布均匀性、齿面接触和齿根弯曲强度安全系数等参数进行对比。对比结果表明,通过优化修形可以使齿面载荷分布更加均匀,提高齿面接触和齿根弯曲强度,进而达到增加齿轮寿命的目的。The reliability of a pair of constant mesh gears in the longitudinal transmission has a great effect upon overall level of the transmission performance,According to the analytic result of a pair of constant mesh gears failure in a vehicle longitudinal transmission,and by using tooth micro-geometry analysis technology in RomaxDesigner software ,the parameters of gear are optimized, The optimum micro-modification of gear tooth profile is performed and the distribution of face load, safety factars for surface durability and bending strength before and after the optimization of profile modification are compared.The results show that through optimization of tooth profile modification,the face load sharing is better,the surface durability and bending strength are improved. The aim of prolonging gear life is achieved.
