Sovereign Gears is a supplier and manufacturer of custom gears with more than 80 years’ experience of serving customers in the UK and across the world. One of the key components we manufacture are Helicals, or Helical Gears

All our gear components are high quality products produced at our workshops in the UK. Our engineers have extensive professional experience of working with gears from a variety of applications and industrial uses. We offer you an individualised service to meet the needs of your business, so contact us today and talk to us about creating the right helicals to fit your machinery.

What is a Helical?

A helical is a round, toothed gear, with teeth built into the outside face side of the gear at a slanted angle. When used in a system with other helical gears, contact begins with the teeth touching, with engagement building gradually as the gears rotate. At the end of the rotation the two gears will be fully engaged.

Helical gears are commonly used components in the automotive industry, where they are frequently utilised in car transmissions. Helicals are commonly made of steel, although other materials can be used.
Please Note: due to the angle of the teeth in helical gears, a thrust load is generated whenever two gears mesh. Systems utilising helical gears must therefore use bearings designed to support this load.

The Benefits of Helicals

There are several reasons helical gear systems can be beneficial in some circumstances:
Smooth Operation: As the engagement between two gears is gradual in helical systems, helical gears enable a smooth and quiet operation. This is an advantage over spur gears and makes helicals ideal for use in car gearboxes.
Perpendicular Shafts: helical gear teeth can be designed to protrude at different angles. When aligned correctly with other helical gears on a perpendicular shaft, the rotation angle can be adjusted by 90°.
