摘　　要：在空间有限、高承载和角向补偿量大的工作条件下,两轴间传递扭矩时需要小型鼓形齿联轴器,但是GB/T 26103.1—2010中的鼓形齿联轴器由于旋转直径大于100 mm、角向补偿量小于1°而无法满足工作要求。通过三维软件模拟小型鼓形齿联轴器加工过程并生成三维模型,对互相接触的内外齿面进行网格细化,建立高精度的鼓形齿联轴器内外全齿的有限元模型,研究在不同轴间偏角时转动过程中的齿面接触状态。模数、齿数是鼓形齿联轴器的基本参数,分析在轴间偏角为5°时不同模数、齿数对鼓形齿联轴器齿面接触情况和最大应力数值的影响,对比总结鼓形齿联轴器在转动中的规律,为小型鼓形齿联轴器的设计提供依据。Under the working conditions of limited space,high load and high misalignment angle,the small crown gear coupling was required to transmit torque between two shafts,however,the crown gear coupling in GB/T 26103.1—2010 could not meet the working requirements due to the rotation diameter greater than 100 mm and the misalignment angle less than 1°.3D software was used to simulate the machining process of the small crown gear coupling and generate a 3D model.The mesh of the internal and external tooth surfaces in contact with each other was refined,and a high-precision finite element model of the full tooth inside and outside of the crown gear coupling was established to study the contact state of the tooth surfaces in the rotation process under different misalignment angles.The modulus and number of teeth were the basic parameters of the crown gear coupling.The influence of different modulus and number of teeth on the contact situation and maximum stress value of the crown gear coupling when the misalignment angle between the axes is 5°was analyzed,and the rule of the crown gear coupling in rotation was compared and summarized,which provides the basis for the design of small crown gear coupling.
