R Series Helical Gearbox Applications

Helical Gearbox VS Worm Gearbox

Worm gearboxes usually consist of a screw called a worm and a much larger interlocking gear. When torque is applied to the worm, the gear will rotate. This allows the operator to determine the speed of the gear rotation. Because the worm gearbox usually only works in one direction-the worm can rotate the gear, but the gear cannot rotate backward and drive the worm when the operation stops; this option provides an automatic locking mechanism. Worm gearboxes can usually be found in the following scenarios: conveyor system, elevator, package, small generator, lifting/towing (crane, winch, hoist), blender, and metal processing.

Helical gearbox unlike worm gearbox, helical gears can move in two directions. The typical cut is from 15 degrees to 30 degrees. The helical gear gets this name because the intersection of the two gears creates a spiral. Helical gearboxes are known for their smooth and quiet operation. A helical gearbox uses its own unique design to generate a considerable thrust (the total thrust is based on the angle of the gear teeth). Helical gear reducers are ideal for high-load applications. Because they typically contain more teeth to make contact and distribute the load stably.

Compared to worm gearboxes, helical gear reducers have a narrower application range, and they are mainly used in the field of automation due to their quiet nature and high thrust capability. Applications of helical gearboxes include conveyor systems, packages, Lifting/pushing (crane, elevator), and stirrers.
