外齿环板是内平动齿轮减速器的关键传动部件,其强度性能直接关系到整机的动态性能。针对新型的三轴对称式三环内平动齿轮减速器,对其基本结构和传动原理进行了分析,并结合静力矩平衡条件和变形协调方程分析外齿板轴承载荷;针对10种不同工况对外齿环板进行了有限元静态分析和模态分析,为进一步探讨内平动减速器广泛实用性提供理论依据。结果表明,外齿环板轴承载荷平稳,运转没有死点;外齿环板应力强度满足要求;且能避开共振区,可以正常工作。

The outer gear ring plate is the key part of the translation in gear reducer drive,its strength is directly related to dynamic performance of the machine. In view of the new type of translation within three axial symmetry type three-ring gear reducer,its basic structure and transmission principle are analyzed,and combining the static moment equilibrium conditions and the deformation coordination equation,the tooth plate bearing load is analyzed. For 10 different working condition of external gear plate finite element static analysis and modal analysis,in order to further explore the translational reducer provides the theory basis for extensive practicability. The results show that the external tooth plate bearing load is smooth,no dead point operation,and the tooth plate stress strength meet the requirements. The resonance region is avoided,can work normally.
