Worm drives are used in presses, in rolling mills, in conveying engineering, in mining industry machines, and on rudders. Furthermore, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
Worm drives are a compact method of substantially decreasing acceleration 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 might be suitable for, specially when the worm drive’s compactness is known as.
Lubrication
Enclosed gears are generally lubricated with oil. The most typical types of oil are rust and oxidation inhibiting, severe pressure, compounded, and synthetic. Other types consist of 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 input and output shafts to retain oil and prevent dirt. The mostly 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 make use of for high-velocity applications, and contain a housing with some rings that limit leakage. A breather is definitely a plug with a hole that’s mounted in the apparatus housing allowing airflow and relieve inner pressure.
A gearmotor combines an enclosed gearset with a motor. A motorized reducer resembles a gearmotor except that it’s driven by another NEMA C-face motor.
