Parameters Analysis of the Offset Slider-Elliptic Crank Dwell Mechanism

Abstract

Elliptic crank is able to generate elliptic curve of the planet mechanism. With the elliptic crank as the driven crank of slider-crank mechanism, the kinematic characteristics of the slider are changed. The offset slider elliptical crank mechanism can be realized in the dwell and quick return characteristics at the same time. The analysis and synthesis methods of the offset slider elliptic crank combined mechanism was proposed which has dwell characteristics at the left side limit position. Some motion properties parameters, such as intermittent range of the slider, minimum transmission Angle, time ratio and slide stroke, was researched. The impacts of main mechanism parameters on the motion properties are analyzed. The parameters of the mechanism are given which has a maximum time ratio with allowable transmission Angle.
