The new STEP export in TBK automatically checks for geometry conflicts delivering robust 3D models for any CAD environment. Efficient, flexible, reliable.
Digital gear design does not end with calculation. It must seamlessly transition into CAD.
The TBK software from GWJ Technology now offers a significantly enhanced 3D STEP export for gears, designed to improve robustness, geometry validation, and flexibility.
Intelligent geometry validation before STEP export: Before generating the 3D tooth geometry as a solid STEP model, TBK now automatically checks:
- Whether an undercut/root fillet intersection is present
- Whether a pointed tooth occurs
- Whether there is any flank interference at the tooth tip/outside diameter
And this is not limited to involute cylindrical gears. The validation is available for:
- External and internal spur gears
- Gear racks
- Involute splines (shafts and hubs)
- Straight and helical bevel gears
- Spiral bevel gears
Even the complex 3D tooth geometry of bevel gears is checked prior to model creation. If geometry conflicts are detected, the software provides clear guidance on how to resolve them saving valuable iteration time.
In addition to solid models with a defined number of teeth, TBK also enables the export of a surface model of the tooth space profile. This surface model is generated without interference checks and can be used in any CAD system.
This allows simple creation of gears, especially bevel gears, with arbitrary blank geometries by applying a boolean subtraction in your CAD system. So, complete gears can be generated efficiently and flexibly.
For users working with CAD systems where no dedicated TBK CAD plugin is available, the new improved STEP export provides a powerful and practical alternative.
Calculation, validation, and CAD integration — now more robust than ever.
