本文首先对用得最多的单销四槽外槽轮机构进行了运动学分析,给出了槽轮的角速度、角加速度的公式和线图,以及拨销对槽轮的相对速度、相对加速度的公式和线图;进而作了动力分析,给出了槽轮的驱动力变化曲线;最后着重指出了槽轮机构高副的磨损破坏性质,导出了赫芝应力的计算公式,分析了整机磨损,提出了改善高副疲劳磨损、提高工作质量和寿命的可行措施。 In this paper, firstly, the kinematics analysis of the single-pin four-slot outer sheave mechanism which is the most used is carried out. The formula and the line diagram of the angular velocity and angular acceleration of the sheave are given, and the relative velocities and relative accelerations Formula and line diagram; and then made the dynamic analysis, gives the curve of the driving force of the sheave; Finally, it points out the wear and tear of the high gear pair and vice versa, derives the calculation formula of Hertzian stress, analyzes the wear of the whole machine , Proposed feasible measures to improve the wear and tear of high secondary fatigue, improve the quality of work and life expectancy.
