Uni-directional ball screw alternatives.
« on: October 07, 2014, 12:47:09 PM »
I am trying to find a one way ball screw to use on a machine I am building.

Basically what I would need is a small spring loaded ball screw with a good amount of threads to spin a motor.

Imagine a yankee screwdriver, but instead of focus on force and bi-directional movement,
a focus on spins and uni-directional movement.

I want a recurring movement to spin the ball screw causing the motion to spin a motor to cause a voltage.
Then when the pressure is released from the actuator, the ball screw would slide back up to starting
position and then begin to spin again when the force is reapplied.

I am not technically married to the idea, and any other suggestions to improve on this would be appreciated.
I also considered using a regular ball screw connected to a regular motor and then using a full wave
rectifier to fix the alternating voltage and create a DC voltage.

Ideas? Improvements? Flaws?
