GearSimulator

This extension allows to simulate gears with exact physics in Omniverse.

This repository is inspired by blender.

Gear analysis is fun but hard. Without getting connect to good physics, the gear simulation cannot be performed accurately. We provide this extension Gear Simulator in Omniverse to support customized gear with customized analysis.

Play with Gear Simulator

1. Create Gear

Set up gear properties and Click Create Gear

We support live editting gear features.

2. Add physics

Right now, the gear is just a mesh with any collision or rigid body.

Click Add Physics to add rigid body, and D6 joint to the gear. The D6 joint allows it to rotate on z-axis.

3. Add Driver

To make the gear rotate by itself, we can click Add Driver with a specific speed.

Additional features

Bind two gear

Two simulate two gears rotate on the same axis, select two gears and

click Bind Gear to add a fixed joint between them.
