Worm drives are used in presses, in rolling mills, in conveying engineering, in mining market devices, and on rudders. In addition, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
Worm drives are a compact method of substantially decreasing rate and increasing torque. Small electric motors are generally high-speed and low-torque; the addition of a worm drive escalates the range of applications that it might be suitable for, particularly when the worm drive’s compactness is considered.
Lubrication
Enclosed gears are generally lubricated with oil. The most common types of oil are rust and oxidation inhibiting, severe 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 strategies are a splash program and a circulating system

Seals and Breathers
Seals are used between your gear housing and insight and output shafts to retain essential oil and prevent dirt. The most commonly utilized type, the radial lip seal, consists of a steel casing that fits into the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-rate applications, and consist of a housing with some rings that limit leakage. A breather can be a plug with a hole that’s mounted in the apparatus housing allowing airflow and relieve inner pressure.
A gearmotor combines a specific gearset with a electric motor. A motorized reducer resembles a gearmotor except that it is driven by 
a separate NEMA C-face motor.
