Worm drives are used in presses, in rolling mills, in conveying engineering, in mining market devices, and on rudders. Furthermore, 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 velocity and increasing torque. Little electric motors are generally high-speed and low-torque; the addition of a worm drive increases the range of applications that it could be suitable for, particularly when the worm drive’s compactness is known as.
Enclosed gears are generally lubricated with oil. The most typical types of oil are rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other types consist of grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash system and a circulating system

Seals and Breathers
Seals are used between the gear housing and input and output shafts to retain oil and prevent dirt. The most commonly used type, the radial lip seal, consists of a metallic casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-velocity applications, and contain a housing with a series of rings that limit leakage. A breather is definitely a plug with a hole that’s mounted in the gear housing to permit airflow and relieve internal pressure.
A gearmotor combines an enclosed gearset with a motor. A motorized reducer resembles a gearmotor except that it’s driven by a separate NEMA C-face motor.
