Screw/Helical Gears for VEX Robotics

One of the least developed areas in current VEX robotics is nonlinear power transfer. Many new opportunities and mechanisms would be possible with updated and modern solutions to transfer power between axes. Currently, products exist such as the worm gear and bevel gears; however, these are often unreliable and difficult to utilize. From experience with bevel gears, one shaft is often left under supported due to the size of the gears and the inability to intersect axles and they are difficult to keep meshed correctly. As for worm gears, there is not much design freedom, as it is often a very slow gear ratio and power can only be transmitted efficiently from one direction.
As a solution to these issues, I have designed for VEX an efficient and elegant real world solution: helical gears (also known as screw gears).
