Forging Steel 20CrMnTi Pinion Single Helix Gear Shaft For Speed Reducer
Advantages of Helical Gears
a) Helical gears can be used with both parallel and non-parallel shafts.
b) Because the teeth engage more gradually, helical gears offer smoother gear operation,
reducing shock loads and causing less noise and vibration.
This makes them ideal for high-speed applications where noise abatement is a requirement.
c) Helical gears are more durable.
They have a higher number of teeth which means less load is placed on each tooth which results in less wear.
d) Helical gears have a high load-carrying capacity.
Its teeth, which are diagonally positioned, are larger in number and length, increasing the surface area of contact.
In addition, the teeth are always in mesh which enables the gears to distribute the load among several axes at all times.
