Durable Single Helical Gear for High-Speed Power Transmission in Industrial Machinery with Low Noise and Vibration

1) Description of Helical Gear

A helical gear is a cylindrical gear whose tooth line is inclined at a certain angle to the axis.

It achieves meshing transmission through spiral tooth surfaces, and the angle between the tooth direction

and the axis is called the helix angle.

2) Feature of Helical Gear
a) High contact ratio: Multiple pairs of teeth are engaged simultaneously, resulting in better transmission smoothness compared to spur gears.
b) Low shock and vibration: It can significantly reduce noise, making it suitable for high - speed operation conditions.
c) Even load distribution on single tooth: This enhances the load - bearing capacity and prolongs the service life.

​3) Working Principle of Helical Gear

When the driving gear rotates, the spiral tooth surface gradually contacts the driven gear along the tooth width direction.

The load is transmitted through multiple tooth surfaces, and the length of the line of action changes dynamically during rotation,

thus achieving continuous and smooth power transmission.

4) Application 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.
