Kinematic Analysis of Mechanism for Converting Rotational Motion into Reciprocating Rotational Motion

The authors propose a distinctive construction of the planetary mechanism with elliptical gears designed to convert rotational motion into reciprocating rotational (oscillating) one. We conducted a kinematic analysis of the mechanism, found the variation of the rotation angle, the angular velocity analogue and angular acceleration analogue of the mechanism output shaft. The developed mechanism is a classic planetary mechanism and is more reliable and compact in comparison with the lever and electromagnetic inverters.
