Idea is to test how WormGear mechanism work when fitted over servo motor.
I carried this test to check whether I will be able to control the flow of liquid passing from pipe added to the slot available in design.
Not much better result but thought I should share it and get some feedback.
After some attempts, I was able to design 3d parts in Fusion360 to be fitted on Servo motor with proper dimensions. Now the Process is simplified, just follow below simple steps to build your own.
Let's begin with the build,
Download STL files and 3d print all parts attached below in custom enclosure section.
After this start with assembly. The procedure is simple and straightforward as shown in below images.
Attach the circular gear on servo shaft. Now place the servo with gear inside the main body touching the linear gear. Use shaft and M4 nut bolt adjustment for proper fitting. Make sure linear gear is freely moving with a rotation of circular gear with sufficient force and not so tightly bound.
Make the connection of servo motor to Arduino UNO as shown in circuit diagram.
I have used digital pin 9 to send a signal to the servo. If you used other then make necessary changes to code also.
Download the Arduino code file from below code section and burn it to Arduino UNO.
NOTE: Please Connect also 12V power Adapter as external supply because alone USB of Arduino board won't be able to supply demanding current by the servo motor.
Here is the Working Demo :
