Worm drives are found in presses, in rolling mills, in conveying engineering, in mining market machines, and on rudders. Furthermore, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash
Worm drives certainly are a compact means of substantially decreasing swiftness and increasing torque. Little electric motors are generally high-speed and low-torque; the addition of a worm drive increases the selection of applications that it could 
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 will be rust and oxidation inhibiting, severe 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 program and a circulating system

Seals and Breathers
Seals happen to be used between the gear housing and insight and output shafts to retain essential oil and prevent dirt. The mostly used type, the radial lip seal, contains 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-rate applications, and consist of a housing with some rings that limit leakage. A breather is usually a plug with a hole that is mounted in the apparatus 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’s driven by a separate NEMA C-face motor.
