What Are Hypoid Spiral Gears?

Hypoid gearboxes are a type of spiral bevel gearbox where the axis doesn’t intersect. This specific gear is between a bevel gear and a worm drive. It’s offset from the gear center and allows for unique configurations to be made, as well as a large diameter shaft. The pitch surface is known as a hyperboloid and the teeth are known as a hypoid gear. Hypoid gears are often used for the output stage because high torques and lower speed are needed.

How They Work

This specific type of gear allows for multiple points of contact, which allows for energy to transfer at any angle. Because of the large diameters, it’s very useful for an abundance of applications. Remember: for energy to be transferred nicely and quietly, the hypoid gears always need lubrication.


The proper gear to use will depend on the job, workload, and environment. If you’re looking for a gear with an offset center, this might just be for you. One example of the most common applications for this specific gear is automotive because it’s used in the rear axle of vehicles and large trucks. This is because vehicle’s and trucks have a center of gravity that is “below center”, which allows for the driveshaft to be lower than the vehicle.
