本文对常用的三齿轮一曲柄摇杆机构的间歇运动特性及动力特性进行了分析研究,给出了机构的特性曲线图,为分析与综合这类机构提供了方便.同时本文还针对软糖包纸机上采用的这种机构进行了改进设计,按最佳传动条件,以及γ_(min)≥60°、三齿轮共面等要求设计得到的最佳机构,在传动效率、运动性能和动力性能等方面均优于原机构.
In this paper, the intermittent motion and dynamic characteristics of the commonly used three-gear-one-crank-rocker mechanism are analyzed and studied, and the characteristic curve of the mechanism is given, which is convenient for the analysis and synthesis of such mechanisms. This kind of mechanism adopted on the paper machine has been improved and designed. According to the optimal transmission condition and the best mechanism designed by γ_ (min) ≥60 ° and three-gear coplanar, etc., in terms of transmission efficiency, sports performance and dynamic performance All aspects are better than the original agency.
