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 may be suitable for, especially when the worm drive’s compactness is known as.
Enclosed gears are generally lubricated with oil. The most common types of essential oil are rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other styles include grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution strategies 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 oil and block dirt. The most commonly utilized type, the radial lip seal, contains a metallic 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-swiftness applications, and consist of a housing with a series of bands that limit leakage. A breather is usually a plug with a hole that’s mounted in the gear housing allowing airflow and relieve internal pressure.
A gearmotor combines an enclosed gearset with a motor. A motorized reducer resembles a gearmotor except that it is driven by a separate NEMA C-face motor.
