A worm gear is a type of gear used in model motors that consists of a screw-like shaft (known as a worm) and a wheel (known as a worm wheel or worm gear). The worm has a helical thread that meshes with the teeth of the worm wheel, causing the wheel to rotate when the worm is turned.
Worm gears are commonly used in model railways as they provide high torque and are very efficient at reducing speed while increasing power. They are also very quiet, making them ideal for use in small-scale models where noise can be an issue.
One of the advantages of using a worm gear is that it can provide a high gear reduction in a single stage, meaning that a small motor can be used to drive a larger load. However, worm gears can also be less efficient than other types of gears, as they can create a lot of friction and heat due to the sliding contact between the worm and worm wheel.
In summary, worm gear is a type of gear used in model motors that provides high torque and efficient speed reduction, making it ideal for use in model railways and other small-scale models.
