The bevel gear with axial offset is used to be called “hyperbolic gear”.

Hypoid Gear

There are also called “hypoid gears” or “quasi-hyperbolic gears”.

The importance of hypoid gears in the development of automotive rear axle assemblies is increasingly valued by developers, and the requirements for gear weight, transmission stability, load carrying capacity, and life expectancy are also increasing.

For hypoid gears, since the tooth surface is a complex curved surface, it is difficult to obtain a more accurate geometric model by the usual method, and it is more difficult to obtain a more accurate finite element model.

To accurately simulate this complex surface contact process, the accuracy of the finite element model is very high.

The more accurate finite element model has a hexahedral finite element model.
