Analysis and Synthesis of the Offset Slider-Elliptic Crank Dwell Mechanism

摘要

Elliptic crank is able to generate elliptic curve of the planet mechanism, with elliptic crank as the driven crank of slider-crank mechanism is equal to the mechanism which has a variable length and a variable speed along the elliptical moving crank, which changed the kinematic characteristics of the slider. T The offset slider elliptical crank mechanism can be realized in the dwell and quick return characteristics at the same time. In this paper the analysis and synthesis methods of the offset slider elliptic crank combined mechanism is proposed which has dwell characteristics at the left side limit position. The calculation method of the performance parameters of the mechanism is given such as minimum transmission Angle, time ratio, etc. The method of determining the parameters of the mechanism are studied on the basis of allowable transmission angle.
