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 sit using high-precision duplex worm drives with adjustable backlash.
Worm drives are a compact method of substantially decreasing quickness 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 could be suitable for, particularly when the worm drive’s compactness is considered.
Lubrication
Enclosed gears are generally lubricated with oil. The most common types of 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 program and a circulating system

Seals and Breathers
Seals are used between your gear housing and insight and output 
shafts to retain oil and prevent dirt. The mostly used type, the radial lip seal, includes a metallic 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 contain a housing with a series of rings that limit leakage. A breather is definitely a plug with a hole that’s mounted in the gear housing allowing airflow and relieve internal pressure.
A gearmotor combines a specific gearset with a electric motor. A motorized reducer resembles a gearmotor except that it’s driven by a separate NEMA C-face motor.
