1)Descriptions of Helical Gear
The teeth of helical gears are arranged spirally with respect to the axis. This unique structure enables at least two or three teeth to be meshing simultaneously during the transmission process, ensuring the continuity and stability of the transmission. According to the direction of the helix, it can be divided into left-handed and right-handed types.
2)Advantages of Helical Gear
a)The running noise is 5-10 decibels lower than that of spur gears.
b)The load-bearing capacity is 15-30% higher than that of spur gears of the same size.
c)Adjust the helix angle to optimize the transmission performance.
d)Suitable for high-speed and heavy-load working conditions
3)Applications of Helical Gear
a)Wind turbine gearboxes
b)Mining machinery transmission system
c)Spindle drive of machine tool
d)Automation production line conveying equipment
