【Abstract】 The authors, with the help of the Vector method, derive the general expression for the contour curve of the swing horsehead on a pumping unit, work out separately the equations of the contour curve of such horsehead driven by linkage and that driven by gear train, and discuss the stroke length and the velocity and acceleration of polished rod on swing horsehead pumping unit driven by each of the two mechanisms.更多还原
