1)Description of Worm Gear Set
Worm gear is a combination of transmission parts made of different materials, the worm is usually made of carbon steel or alloy steel,
and the worm wheel is mostly made of copper alloy (e.g. tin bronze) with excellent friction-reducing properties,
which can achieve high efficiency transmission through reasonable material selection.
2)Advantages of Worm Gear Set
a) Strong material adaptability: choose the right material according to the working condition, high strength of worm gear
and good friction reduction of worm gear can improve transmission efficiency and life.
b) Good wear resistance: Copper alloy worm gear and steel worm gear can effectively reduce friction and wear, reduce maintenance costs.
c) Good fatigue resistance: high quality material and heat treatment process make the worm gear have good fatigue resistance
and adapt to long-term continuous work.
3)Working Principle of Worm Gear Set
Worm gears of different materials transmit power through surface contact, the hardness of the worm is higher, the worm wheel is relatively softer,
and the wear mainly occurs on the worm wheel, which is easy to replace and maintain.
When working, the friction and lubrication status between materials affect the transmission efficiency and service life.
4)Application of Worm Gear Set
It is suitable for heavy-duty transmission of metallurgical machinery, lifting mechanism of mining equipment, and propulsion system of ships, etc.
It operates stably under severe working conditions with high load and lubrication conditions.
