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 certainly are a compact means of substantially decreasing speed and increasing torque. Little 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, especially when the worm drive’s compactness is known as.
Lubrication
Enclosed gears are generally lubricated with oil. The most common types of oil are rust and oxidation inhibiting, extreme 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
Worm Reduction Gearbox Application:
Seals and Breathers
Seals are used between the gear housing and input and result shafts to retain oil and block dirt. The mostly used type, the radial lip seal, contains 
a metal casing that fits in to the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-swiftness applications, and contain a housing with a series of bands that limit leakage. A breather is a connect with a hole that is mounted in the gear housing to permit airflow and relieve internal 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.
