Helical Gear
Use the Helical Gear node to model a helical gear in 2D and 3D. The gear is assumed to be rigid. Select one or more domains to make them a part of the gear.
A helical gear can be connected to the following gear types:
•
Another Helical Gear, or a Spur Gear through the Gear Pair node.
•
A Worm Gear through the Worm and Wheel node.
•
A Helical Rack, or a Spur Rack through the Rack and Pinion node.
Any two gears or rack can be connected to each other only if they satisfy the Gear Pair Compatibility Criteria.
