A worm gearbox, also known as a worm gear reducer, is a type of power transmission gearbox that uses a worm gear to transmit power between two shafts at right angles to each other. The worm gear consists of a screw-like thread that meshes with a toothed gear wheel, known as a worm wheel or worm gear. An advantage of a worm gearbox is its ability to achieve a high gear reduction ratio in a compact design. This makes it ideal for applications where space is limited, such as in conveyor systems, machine tools, and automotive applications. Worm gearboxes are also known for their high efficiency, as they can transmit power smoothly and quietly, with minimal friction and wear. They are also self-locking, which means they can hold their position without the need for a separate braking mechanism.
