齿轮齿向载荷分布的研究

采用实验研究与有限元计算相结合的方法研究齿轮齿面载荷分布规律，包括齿面均匀接触与一端接触时齿面载荷的分布规律；齿端修整与柔性齿轮结构对齿面载荷分布的影响．研究证明：均匀接触与一端接触都存在载荷集中现象，但应力不均匀程度后者是前者的１．５～２．０倍；齿端修整与增大齿轮结构的柔性是改善齿面载荷分布的有效措施．

Study on Longitudinal Load Distribution on Gear Tooth

Regularity of longitudinal load distribution on gear tooth when tooth faces are contacted uniformly and when only tooth ends are contacted, and influence on distribution exerted by longitudinal correction and flexible gear structure, are studied in the paper with method of finite element calculation combined with experiment. Research shows that load concentration exists on the conditions of uniform contact or one-end contact, and in the later case the stress nonuniformity factor on root is 1.5 to 2.0 times larger than in the former case. It also verifies that longitudinal correction and increased flexibility of gear structure are effective to improve longitudinal load distribution.
