A worm shaft is a crucial component in a worm gearbox, which is a type of gearbox that consists of a worm gear (also known as a worm wheel) and a worm screw. The worm shaft is the cylindrical rod upon which the worm screw is mounted. It typically has a helical thread (the worm screw) cut into its surface.
Worm gear worm shafts are usually made of materials such as steel stainless steel bronze brass copper alloy steel  etc , depending on the application’s requirements for strength, durability, and resistance to wear. They are precisely machined to ensure smooth operation and efficient power transmission within the gearbox.
