Vertical Reducation Gear Boxes.

Worm Gearboxes is the type of gear system in which higher torque is achieved with low speed gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm reduction gears having screw type qualities are similar to helical gears, but its helix angle is typically comparatively larger) and its body is normally quite long in the axial direction. The gears in these gearboxes can be right or left-handed depending upon the purpose.
