1)Descriptions of Helical Gear

A helical gear is a kind of gear whose tooth direction is at a certain angle (screw angle) to the axis. Compared with a straight gear, it has the characteristics of smoother meshing and stronger load-bearing capacity. Its tooth profile is arranged in a helical line, enabling progressive meshing and significantly reducing transmission shock and noise.
2)Features of Helical Gear
a)Smooth transmission: The progressive meshing of helical gears significantly reduces vibration and noise, making it suitable for high-speed applications.
b)High load-bearing capacity: With a large number of simultaneously meshing teeth, the load distribution is more even, and the lifespan is longer.
c)Multiple installation methods: can be arranged in parallel axis or cross axis, with high design flexibility.
d)Transmission efficiency: Usually it can reach over 98%, with low power loss.
3)Applications of Helical Gear
a)Automobile gearbox
b)Industrial reducer
c)Marine propulsion system
d)Power generation equipment transmission device
