        摘要：This paper introduces a kind of step motion mechanism of cam chain with coaxial input and output axes,studies its transmission functions from zeroth to second order,presents the geometry conditions that make the output of the driven sprocket wheel as a constant transmission ratio in the middle part of step angle and the design method of mechanismic dimensions with given step angle.The design example has shown that both the design method and monufacture of the step motion mechanism are simple and the transmission is steady.

        摘要：In this paper,the working principle of the mechanical auto reversing device is introduced.The working load and energy consumption of the device in the reversing operation is analyzed.The formulas for calculating the critical thrust for driving plate to reserve rotation are derived.The criterion of selection and calculation of the spring parameters during storing energy are determined.The test result of sample device shows that the reversing principle is correct and feasible,and the device have the features of little reverse impact force and high driving efficiency.
