A worm drive defined as a type of gear arrangement in which a worm-shaped (which is a gear in the form of a screw) meshes with a worm gear (which is similar in appearance to a spur gear) formed. This type of worm drive gear arrangement reduces rotational speed or transmits higher torque. An electric motor or engine applies rotational power to the worm. As a result, the worm rotates against the wheel, and the screwface pushes on the teeth of the wheel. So that the wheel pushed against the load. Basically, a worm gear designed as a screw butted up against what looks like a standard spur gear with slightly angled and curved teeth.
This worm drive is capable of changing the rotational movement by 90 degrees. And the plane of movement also changes due to the position of the worm on the worm wheel. Worm Gear Box Reduction Motor basically all metal gear made up of a steel worms and brass wheels. The main reason to use worm gear is it offers a massive reduction ratio with less effort. All you need to do is add circumference to the wheel. Thus you can use it to either greatly increase torque or greatly reduce speed. A second reason to use a worm gear is the inability to reverse the direction of power. Due to the friction between the worm and the wheel, its virtually impossible for a wheel with force applied to it to start the worm moving.
This worm Gearbox operates at a voltage range of DC 12 V with a rated speed of 175RPM at a rated torque of 30 kg-cm. This gearbox function using precious metals carbon brush. Thereby offers Long service life, low noise, large torque. It features Stable and reliable performance as it can rotate and reverse, and thus work more accurately. In this Gear Dc Motor with Micro-Turbine Worm, you can change the wiring connection to change motor rotation. This all-metal gear features high-temperature resistance, high abrasion resistance, strong load capacity, thereby effectively protect the turbo worm gear box motor body.
