Introduction 

The Whitworth quick return mechanism converts rotary motion into reciprocating motion, but unlike the crank and slider, the forward reciprocating motion is at a different rate than the backward stroke. At the bottom of the drive arm, the peg only has to move through a few degrees to sweep the arm from left to right, but it takes the remainder of the revolution to bring the arm back. This mechanism is most commonly seen as the drive for a shaping machine.

Abstract—


A geometric relationship and mathematical model of pressure angle of elliptical gears are developed based on the theory of gearing, and some constraints of pressure angle are presented in order to prevent gear teeth from coming out of mesh. The results show that the ....etc

ABSTRACT

Traditionally, input shaping has been used outside the feedback control loop. Utilizing input shaping in this way prevents it from directly addressing some important vibration control issues such as disturbances, nonzero initial conditions, actuator saturation, etc., These potential applications, however, will never be fully exploited unless a good understanding exists of how to create stable CLSS controllers.
