Worm Gear

This free download offers an AutoCAD DWG drawing extension featuring 2D views, including plan and elevation drawings of a worm gear, also known as a screw gear or worm drive. 

The detailed designs showcase the unique mechanism of this gear system, which consists of a worm (a type of gear resembling a screw) that meshes with a worm wheel to transmit motion and torque between non-intersecting shafts at a 90-degree angle.
