Figure 4 (a) and (b) show a worm wheel and belt that transfer the rotational motion into linear motion. To carry
linear motor can be used in order to reduce the complexity of design. In this particular case, the whole actuator
parts need to combine in order to work with it successfully. For transferring rotational motion into linear motion a
pulley and belt system is necessary. Belt and pulley are setup on a machine consisting of two rounds, fixed pulleys.
One pulley is powered and thus moves a belt, which in turn moves the other pulley and finally transferred the
rotational motion into linear one. Depend on the design belt and pulley system may vary. According to the needs it
should be designed to avoid misalignment as well as male functioning.
