Worm drives are used in presses, in rolling mills, in conveying engineering, in mining market devices, 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 method of substantially 
decreasing swiftness and increasing torque. Small electric motors are usually high-speed and low-torque; the addition of a worm drive increases the selection of applications that it may be suitable for, especially when the worm drive’s compactness is considered.
Lubrication
Enclosed gears are usually lubricated with oil. The most typical types of essential oil are rust and oxidation inhibiting, intense pressure, compounded, and synthetic. Other styles include grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash system and a circulating system

Seals and Breathers
Seals are used between the gear housing and insight and output worm reduction gearbox shafts to retain essential oil and block dirt. The most commonly utilized type, the radial lip seal, contains a metal casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-rate applications, and contain a housing with a series of bands that limit leakage. A breather is definitely a plug with a hole that is mounted in the gear housing allowing airflow and relieve inner pressure.
A gearmotor combines an enclosed gearset with a electric motor. A motorized reducer resembles a gearmotor except that it’s driven by a separate NEMA C-face motor.
