Worm gearboxes provide high torque 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. Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single or double), with torque arm or torque limiter. Some of the applications of a worm gearbox are mining, printing press, rolling mills, escalator or elecators systems, manufacturing, packaging, small machinery and conveyors etc.
