High Efficiency Single Helical Gear For Smooth And Quiet Operation

1)Descriptions of Helical Gear

A helical gear is a cylindrical gear whose tooth line forms a certain angle (screw angle) with the gear axis.

Its tooth profile is distributed in a spiral manner.
2)Features of Helical Gear
a)The tooth line is not parallel to the axis line; instead, it extends in a spiral manner.

b)During meshing, the contact line is inclined and gradually enters and exits the meshing position.

c)Can be designed to be in either left-handed or right-handed orientation.

3)Advantages of Helical Gear
a)Transmission is more smooth: Progressive meshing reduces shock and vibration.

b)More quiet operation: The noise is reduced by approximately 10-15 decibels compared to spur gears.

c)Higher carrying capacity: The number of meshing teeth is greater than that of straight gears.
