Linear Motion Machine using Rack & Pinion and Lever & Fulcrum Techniques.

thingiverse

You can build a linear motion device with these 3D components that utilize the Rack & Pinion method and Lever & Fulcrum method to produce smooth motion from a rotating driving wheel with an inserted pin. This design allows for custom adapters to be created that fit onto the rack section of the device, featuring a 1/2 inch diameter hole for inserting a neodymium circular magnet. The effects of this magnet on coils of magnet wire can be studied as it moves back and forth in linear motion. To assemble the device, 1/4 inch nuts, bolts, and washers are used to secure the components together. A single 608 size skate bearing is incorporated into the design for added functionality. A 1/2 inch diameter bearing supports the rotating pin in the driving wheel, ensuring smooth operation. When testing the device, a table top vise can be employed to securely hold it in place. These 3D parts were created using the EMachineShop software package, taking advantage of its freeware capabilities.
