Bevel Gear Theory
The Bevel Gear model is defined as a rigid body. A finite stiffness for the gear mesh (or gear tooth) can be specified in the Gear Pair node while connecting to other gears. Similar to the rigid domain, the bevel gear is a material model, which is mutually exclusive to all other material models. The only material property needed is the mass density.

For details about the theory of a rigid body, see the Rigid Domain Model in the Structural Mechanics Module User’s Guide.
The following section is an addition to the Spur Gear Theory section, some of which is also applicable for the bevel gear.
Connection to Other Gears
A bevel gear can be connected to another Bevel Gear through the Gear Pair node. A single gear can be connected to one or more gears.
Gear Properties
The additional parameter cone angle (γ) is required to define a bevel gear. The positive cone angle results in a decrease in diameter along the gear axis.
