【Abstract】 The displacement curve of the crank sliding-block mechanism was deduced to be an approximate ellipse.The working principle was analyzed for the middle-bulged varying ellipse shape of the two-freedom mechanism with the crank sliding-block mechanism and the cam mechanism.The equation for calculating the sliding-block stroke and the cam route was given out.The shaping error of the mechanism was analyzed.更多还原
