本文对曲拐传动多轴钻的传动机构的设计原则及计算作了一些理论上的探讨,提出了设计上需要注意的关于机构的构成条件、主动轴最佳位置的选取、拐销受力分析、机构的平衡等问题,并从机构学、运动学和动力学上作了分析和讨论,供设计者参考。 This paper makes some theoretical discussions on the design principle and calculation of the transmission mechanism of the crank driving multi-axis drill, puts forward the design conditions that need to pay attention to about the structure of the mechanism, the selection of the optimal position of the driving shaft, , The balance of institutions and other issues, and from the mechanics, kinematics and dynamics made analysis and discussion for the designer’s reference.
