Worm drives are used in presses, in rolling mills, in conveying engineering, in mining worm reduction gearbox sector devices, and on rudders. In addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
Worm drives are a compact means of substantially decreasing velocity and increasing torque. Small electric motors are generally high-speed and low-torque; the addition of a worm drive escalates 
the selection of applications that it could be suitable for, particularly when the worm drive’s compactness is known as.
Lubrication
Enclosed gears are generally lubricated with oil. The most typical types of essential oil are rust and oxidation inhibiting, intense 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 program and a circulating system

Seals and Breathers
Seals are used between the gear housing and input and result shafts to retain essential oil and block dirt. The most commonly utilized type, the radial lip seal, consists of a metallic casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-speed applications, and consist of a housing with some bands that limit leakage. A breather can be 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 engine. A motorized reducer resembles a gearmotor except that it’s driven by a separate NEMA C-face motor.
