1)Descriptions of Helical Gear
Helical gears are one of the most commonly used gear types in industrial transmission,
and are widely applied in various mechanical transmission systems.
2)Features of Helical Gear
a)The manufacturing process is more complicated than that of spur gears and requires specialized machine tools.
b)It can be designed as either a parallel-axis or an interlaced-axis transmission.
c)Common materials include alloy steel, cast iron, etc.
3)Advantages of Helical Gear
a)Wide application range: from small instruments to large industrial equipment.
b)High transmission efficiency: up to over 98%.
c)Installation flexibility: By adjusting the helix angle, the transmission performance can be optimized.
