1)Description of Worm Gear Set
Worm gear is dependent on good lubrication conditions to achieve efficient transmission of mechanical components,
the lubrication state on its friction, wear and transmission efficiency has an important impact.
2)Advantages of Worm Gear Set
a) Clear lubrication requirements: through the selection of suitable lubricants and lubrication methods,
can reduce the coefficient of friction, improve transmission efficiency.
b) Outstanding friction-reducing performance: good lubrication can form an oil film between tooth surfaces,
reduce direct metal contact, reduce wear and prolong service life.
c) Good heat dissipation: lubricant can take away the heat generated by friction in the process of circulation,
prevent overheating of parts and ensure stable operation of the transmission system.
3)Working Principle of Worm Gear Set
Under lubrication conditions, a lubricant film is formed between the worm gear tooth surfaces, and the force is transmitted through the film.
The viscosity, oiliness and extreme pressure properties of the lubricant affect the formation and stability of the film,
which in turn affects the transmission efficiency and the degree of wear.
4)Application of Worm Gear Set
Suitable for continuous operation of industrial equipment, such as the drive system of textile machinery,
food processing machinery power transmission devices, etc., in the lubrication requirements,
the cleanliness and noise control of a certain standard environment.
