倒悬挂颚式破碎机动颚上下端行程的精确计算

Accurate Calculation of Topping Travel and Bottom Travel of Swing Jaw of Fine Jaw Crusher with Swing Jaw in A Certain Inversional Hang

应用平面曲柄摇杆机构极限位置的几何关系，导出了复摆型倒悬挂颚式破碎机上下端行程和特性系数（行程比）的精确计算公式，为该破碎机设计研究提供了计算依据，避免了以往图解法的计算误差。

The paper derives the accurate calculating formulae of topping travel and bottom travel as well as travel characteristic coefficient (travel ratio) of swing jaw of the fine single-toggle jaw crusher with swing jaw in a certain inversional hang based on applying the geometrical relationship of the limit position of crank and rocker mechanism. Therefore, the calculating basis is provided for design and research of this machine, thus avoiding the calculaling error of graphic method.
