Helical Gears

Helical gears are like spur gears in that they are usually manufactured from cylindrical gear blanks and are most frequently used to transmit power and motion between parallel shafts. Drawing on over 80 years of industry experience, our technicians will work with you to determine whether Helical or spurs gears best match your design requirements. The primary difference between spur gears and helical gears is spur gear teeth are oriented parallel to the axis of rotation, and helical gear teeth are cut at an angle. Because of this, helical gears can be used to transmit motion between shafts that are situated at various angles in different planes. helical gears will also run smoother and quieter than spur gear pairs in parallel shaft arrangements. Additionally, because meshed helical gears will have more teeth in contact with mating gears at any time, helical gears can transmit higher loads than spur gears of the same size.

Helical Gear Experience

Geartronics produces helical gears in a multitude of configurations from a wide-variety of materials with helix angles as steep as 45-degrees. The helical gears we currently produce for our customers are typically used in applications where noise reduction is of primary importance and/or where space is limited.

We have manufactured helical gears for customers from a number of industries, including:
