The reciprocating rectilinear moving mechanism is applied widely in the industry, which is now usually driven by the non-symmetrical mechanism. Due to the changing radial force generated by the slider, the big friction loss and the vibration noise are caused. And, the size of travel in reciprocating motion is fixed and can not be adjusted. In order to overcome these defections, the reciprocating rectilinear moving mechanism at high frequency driven by the stepper or servo motors based on two symmetrical cranks is innovated in this paper, in which the linear movement is converted by the two cranks. The radial forces in this innovated mechanism are quite symmetrical and balanced, so the friction loss can be almost ignored and the oscillation noise is very small too. Then, through programming, the angle range of stepper or servo motors can be controlled to output any required displacement and any required force. Thus, the scope of application of this mechanism is expanded extremely.
