Worm drives are used in presses, in rolling mills, in conveying engineering, in mining industry devices, and on rudders. Furthermore, milling heads and rotary tables are positioned using high-precision duplex worm drives 
with adjustable backlash
Worm drives are a compact means of substantially decreasing velocity and increasing torque. Small electric motors are usually high-speed and low-torque; the addition of a worm travel increases the range of applications that it may be suitable for, particularly when the worm drive’s compactness is known as.
Lubrication
Enclosed gears are usually lubricated with oil. The most common types of oil will be rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other types include grease and solid film. Grease can be utilized for worm, planetary, cycloidal, and hypoidal reducers. Common distribution strategies are a splash system and a circulating system

Seals and Breathers
Seals will be used between your gear housing and insight and output shafts to retain oil and prevent dirt. The mostly utilized type, the radial lip seal, contains a metallic casing that fits in to the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals happen to be use for high-speed applications, and consist of a housing with a series of bands that limit leakage. A breather is a plug with a hole that’s mounted in the gear housing allowing airflow and relieve internal pressure.
A gearmotor combines an enclosed gearset with a motor. A motorized reducer resembles a gearmotor except that it is driven by a separate NEMA C-face motor.
Have you thought about worm reduction gearbox as a normal component of your life?
