摘　　要：在建立等距型面与平键联接强度计算的有限元模型基础上，通过上机计算，找到了这两种联接在传递扭矩时各自应力的大小和分布规律以及扭矩与应力之间的关系，从而得出了它们在强度方面的定量差别．On the basis of establishing the geometric model that calcutating the strength of equidistant profile connection and parallel key connection with finite element method, the stress and their distribution of this two connections, and relations between torque and stress are found out when they are undertaking the torque. Therefore, the quantitative strength differences between the two connections are found out.
