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 are positioned using high-precision duplex worm drives with adjustable backlash.
Worm drives 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 increases the range of applications that it might be suitable for, specially when the worm drive’s compactness is considered.
Enclosed gears are usually lubricated with oil. The most typical types of oil are rust and oxidation inhibiting, intense 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 your gear housing and input and output shafts to retain oil and prevent dirt. The most commonly used type, the radial lip seal, contains a metal casing that fits into the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-swiftness applications, and consist of a housing with some rings that limit leakage. A breather can be a connect 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 is driven by another NEMA C-face motor.
