Helical Gears

Custom Helical Gears Manufacturer

Avon Gear & Engineering manufactures a full line of custom helical gears and drives. We manufacture high quality helical gears for many industries, from small to large in a variety of size ranges.

What are helical gears?

Helical Gears have teeth which are set at an angle. Helical gears and spur gears are very similar except that the teeth of a helical gear are cut at an angle to the axis or hole. These teeth typically engage more slowly and smoothly than spur and other types of gears used for similar applications, because the load is transferred uniformly and gradually. This results in superior performance and reduced noise and vibration. When used on parallel shafts, helical gears are similar to spur gears, but generally provide a stronger, smoother running gear train. When used on shafts at right angles, these helical gears are commonly known as spiral gears or crossed axis helical gears. Helical gears are made in both right and left hand configurations.

Accurate gears require accurate gear blanks; for better control at this critical stage of gear manufacturing, Avon Gear manufactures custom helical gears with our own gear blanks. We also have the capabilities to manufacture custom helical gears in a variety of materials.
