    What is a Worm Gear?
    A worm gear is a staggered shaft gear that creates motion between shafts using threads that are cut into a cylindrical bar to provide speed reduction. The combination of a worm wheel and worm are the components of a worm gear. Speed reduction is determined by the number of worm threads and the number of teeth on the worm wheel.
    The advantages of worm gears include noise and vibration reduction as well as compactness. They are made of hardened metals because of the amount of heat they generate.
    How Worm Gears are Made
    A worm gear is the most compact type of gearing system. They are capable of being placed in very small spaces and still providing high ratio speed reduction. With proper mounting and installation, worm gear systems operate smoothly and quietly.
    The typical method for manufacturing worm gears is hobbing using a hob or cutting tool; this cutting tool is similar to the gear with which the worm gear will mate. Worms can be turned, hobbed, milled, or ground.
    How are Worm gears being made
    Hobbing
    Hobbing is a method for producing gear teeth using a set of customized bits that are designed to make the correct pitch for the gear’s application. Hobbing is a cold working forging process where a punch with the correct geometry is pressed into the workpiece.
    The tool that is used, the punch, is referred to as a hob and is made of hardened steel that forms a helical hob cutter. The pressure and cold forging produce very accurate dimensions and excellent surface quality in the cavities.
    Hobbing machines are fully automated and come in a wide variety of sizes to enable them to produce extremely small gears as well as large gears. The two parts of a hobbing machine include two spindles—one to hold the workpiece and one to hold the hob.
    Types of Worm Gears
    One of the major benefits of worm gears is their ability to offer gear reduction and torque multiplication in a small footprint. The construction of a worm gear includes a large worm wheel that has a shallow thread and is connected to a perpendicular axes, non-intersecting gear.
    For worm gears, the positioning and assembly of the teeth is critical since a very strict tooth design is required for the wheel gear and the worm gear to determine how the gears meet. Variations are dependent on how the gears touch.
    The two basic types of worm gears are cylindrical or straight and cone or double enveloping. The faces of worm gears are broken into straight, hobbed, and concave. Cylindrical worms are the most common and widely used.
