Worm drives are used in presses, in rolling mills, in conveying engineering, in mining market machines, 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 method of substantially decreasing acceleration and increasing torque. Small electric motors are usually high-speed and low-torque; the addition of a worm drive escalates the selection of applications that it may be suitable for, specially 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 types 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 input and result shafts to retain oil and block dirt. The most commonly utilized type, the radial lip seal, includes a steel casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-swiftness applications, and contain a housing with a series of bands that limit leakage. A breather is certainly a connect with a hole that’s mounted in the gear housing to permit airflow and relieve inner pressure.
A gearmotor combines an enclosed gearset with a electric 
motor. A motorized reducer resembles a gearmotor except that it is driven by a separate NEMA C-face motor.
