A Simple 3D Printed Whitworth Quick Return Mechanism.

"A Simple 3D Printed Whitworth Quick Return Mechanism" is another model I designed for a mechanisms class.

The motor used in this model is an N20 60RPM 6VDC gear motor powered by a 3VDC battery pack, thus the motor runs at approximately 30RPM.

With the motor gear having 12 teeth, and the yoke gear having 24 teeth, the yoke gear rotates at approximately 15RPM and as such the arm completes its rotary translation cycle in approximately 4 seconds. The motion of the arm is faster from left to right than right to left due to the nature of the Whitworth Quick Return mechanism. In this model, the arm rotates += 14 degrees.

As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes.

Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.12.1, and 3D printed in PLA on Ultimaker S5s.
