Abstract:
1. A rotary-to-linear motion actuator, comprising: a rotatable actuator sleeve having a helical bevel ring gear and external threads around an outer circumference of said rotatable actuator sleeve, said helical bevel ring gear arranged along a helical path about said outer circumference of said rotatable actuator sleeve at a same pitch as said external threads on said rotatable actuator sleeve; and a stemmed pinion gear engaged with said helical bevel ring gear affixed to said rotatable actuator sleeve; wherein rotation motion of said stemmed pinion gear is transferred to rotational motion of said helical bevel ring gear about said helical path, wherein said rotation motion of said helical bevel ring gear about said helical path is transferred to linear movement of said rotatable actuator sleeve along a path.
