对心椭圆曲柄滑块间歇运动机构综合
|
摘要
椭圆曲柄是能够生成椭圆曲线的行星机构,用椭圆曲柄替代曲柄滑块机构的驱动曲柄,相当于一个具有变化的长度和速度、沿着椭圆曲线运动的曲柄,从而改变了滑块的运动特性。文中提出了在工作行程具有短暂间歇运动特性的对心椭圆曲柄滑块机构,分析了间歇机构的形成条件,推导了机构综合的基本方程,并按3种不同的已知条件分别给出了间歇机构综合的具体方法。按照机构尺寸限制和曲柄存在条件等,分析了机构参数的选择范围。
Elliptic crank is a planet mechanism which generates elliptic curves;if the elliptic crank replaces the crankslider mechanism's driven crank,the mechanism has a crank of varying length and speed,which moves along the elliptical,thus changing the kinematic characteristics of the slider.In this article,the on-line elliptic crank's slider mechanism characterized with a short intermittent dwell in the working stroke is developed,the analysis is conducted on how the dwell mechanism is formed,the basic equation of synthesis is deduced,and according to the three different known conditions,the synthesis methods of the dwell mechanism are presented respectively.Based on the mechanism's size limit and the crank's existence conditions,the selection range of mechanism parameters is analyzed.
