Worm drives are found in presses, in rolling mills, in conveying engineering, in mining market devices, and on rudders. In addition, 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 acceleration and increasing torque. Small electric motors are generally high-speed and low-torque; the addition of 
a worm drive escalates the range of applications that it may be suitable for, especially when the worm drive’s compactness is considered.
Lubrication
Enclosed gears are generally lubricated with oil. The most typical types of oil are rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other styles consist of grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash program and a circulating system

Seals and Breathers
Seals are used between the gear housing and insight and output shafts to retain essential oil and block dirt. The most commonly used type, the radial lip seal, contains a steel casing that fits into the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-velocity applications, and consist of a housing with some bands that limit leakage. A breather can be a plug with a hole that is mounted in the apparatus housing allowing airflow and relieve inner pressure.
A gearmotor combines a specific gearset with a electric motor. A motorized reducer resembles a gearmotor except that it’s driven by another NEMA C-face motor.
