Worm 
drives are found in presses, in rolling mills, in conveying engineering, in mining sector 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 method of substantially decreasing velocity and increasing torque. Little electric motors are generally high-speed and low-torque; the addition of a worm travel increases the selection of applications that it might be suitable for, specially when the worm drive’s compactness is considered.
Lubrication
Enclosed gears are generally lubricated with oil. The most common types of oil happen to be rust and oxidation inhibiting, intense pressure, compounded, and synthetic. Other styles include grease and sturdy film. Grease can be utilized for worm, planetary, cycloidal, and hypoidal reducers. Common distribution strategies are a splash program and a circulating system

Seals and Breathers
Seals happen to be used between your gear housing and input and output shafts to retain oil and block dirt. The mostly used 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 will be use for high-quickness applications, and consist of a housing with some rings that limit leakage. A breather is a plug with a hole that’s mounted in the apparatus housing to permit airflow and relieve inner pressure.
A gearmotor combines an enclosed gearset with a engine. A motorized reducer resembles a gearmotor except that it is driven by another NEMA C-face motor.
