Worm drives are found in presses, in rolling mills, in conveying engineering, in mining industry machines, and on rudders. In addition, 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 swiftness and increasing torque. Little electric motors are usually high-speed and low-torque; the addition of a worm travel increases the range of applications that it might be suitable for, especially when the worm drive’s compactness is known as.
Lubrication
Enclosed gears are usually lubricated with oil. The most common types of oil are 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 methods are a splash program and a circulating system
Worm Reduction Gearbox Application:
Seals and Breathers
Seals will be used between your gear housing and insight and output shafts to retain essential oil and block dirt. The most commonly used type, the radial lip seal, consists of a metal casing that fits in to the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-velocity applications, and consist of a housing with a series of bands that limit leakage. A breather is a connect with a hole that’s mounted in the 
gear housing to permit airflow and relieve internal pressure.
A gearmotor combines an enclosed gearset with a electric motor. A motorized reducer resembles a gearmotor except that it is driven by a separate NEMA C-face motor.
