1)Descriptions of Helical Gear
By using specific metal materials (such as carbon steel, alloy steel, etc.) or non-metallic materials (such as engineering plastics),
and through processing, gears with spiral tooth profiles are manufactured, which are called helical gears.
2)Advantages of Helical Gear
a) Diverse material selection: Based on different usage scenarios and performance requirements, appropriate materials can be chosen.
For example, carbon steel has low cost and is easy to process; alloy steel has high strength and good wear resistance;
engineering plastics with helical gears have the characteristics of light weight, low noise, and self-lubrication.
b) Strong adaptability: Different materials of helical gears can meet the transmission needs in various working conditions,
such as high temperature, corrosion, low speed and light load in special environments.
3)Applications of Helical Gear
Metal helical gears are commonly used in industrial machinery, aerospace and other high-load transmission fields;
engineering plastic helical gears are mostly used in office equipment, medical devices, toys and other occasions where noise
and weight requirements are higher.
