# Bevel gear mesh

> Connection kind `bevel-mesh` (category `mech`, DSL name `bevelMesh`, API v1)

Couples two bevel gears of the same module. Axes meet at pitchAngle_a + pitchAngle_b (typically 90° for mitre bevels).

## Accepted ports

- `bevel-gear.axis` → `bevel-gear.axis`

## Parameters schema

_No parameters._

## Kinematics

ω_driven = -ω_driver · (teeth_driver / teeth_driven). Same ratio as spur-gear mesh; only the axis geometry differs.

## Layout

This connection computes the driven component position from the anchor.

## Example

```
connect B1.axis -> B2.axis with mech.bevelMesh
```
