This paper outlines the technical capabilities and workflow of Camnetics GearTrax , specifically focusing on the 2021 version's role in streamlining the design and modeling of drive components within major CAD environments like SolidWorks , Autodesk Inventor, and Solid Edge .
Title: Modernizing Drive Component Modeling with GearTrax 2021 1. Introduction
Traditional gear design is often a labor-intensive process requiring hours of manual calculation and complex sketching in CAD software. GearTrax 2021 provides a robust alternative by allowing designers to create precise solid models in seconds, bridging the gap between expert gear knowledge and general design requirements. 2. Core Modeling Capabilities
GearTrax 2021 supports a wide range of drive components, including:
Gears: Spur, helical, bevel (straight and spiral), worm gears, and elliptical gears.
Splines: True involute tooth profiles for both internal and external splines.
Pulleys & Sprockets: Timing belt pulleys, V-belt pulleys, and chain sprockets.
Advanced Mechanisms: Cycloidal drive gears and rack-and-face gears. 3. Key Features and Enhancements
Intuitive Animation: A dedicated animation window allows users to visualize the gear mesh in real-time , helping them understand how parameter changes (like tooth count or pressure angle) impact physical performance.
CAD Integration: The software acts as a dynamic plugin , directly generating parts and assemblies within the host CAD system using native features like cut-extrudes rather than simple boss-extrudes to better mimic manufacturing processes.
Data Management: Users can export design data directly to Excel, CSV, or text files to create comprehensive data sheets for manufacturing and documentation. The 32-bit Hangover: Geartrax 2021 still struggled with
Standard vs. PRO Versions: The PRO version offers additional functionality, including a full-screen mode and the ability to modify existing models created by the software. 4. Design Workflow
Selection: Choose the component type (e.g., spur gear) and the target CAD system.
Parameterization: Input specific mechanical data such as module, number of teeth, bore diameter, and pressure angle.
Visualization: Use the animation module to verify the mesh and check for potential interference.
Generation: Execute the "Create" command to automatically build the 3D geometry and assemblies in the CAD environment. 5. Conclusion
GearTrax 2021 remains a critical tool for mechanical engineers, significantly reducing the design cycle by automating the generation of complex gear geometry while ensuring high accuracy through its adherence to true involute profiles. GearTrax | Camnetics, Inc. - SolidWorks
Here are a few options for a post about Geartrax 2021, depending on your target audience (technical engineers vs. general CAD enthusiasts) and the platform you are using (LinkedIn vs. a blog).
Performance transmission shops use GearTrax to design custom gear sets for drag racing or off-road vehicles, where standard OEM gears are insufficient.
With the rise of printed gears, GearTrax 2021 has become a favorite among makers. Exporting high-resolution involute gears to STL for FDM or SLA printers yields quiet, efficient plastic gears.
Issue: GearTrax 2021 does not appear in SolidWorks Tools menu.
Solution: In SolidWorks, go to Tools > Add-Ins. Browse for GearTrax2021.swAddIn and enable it.
Issue: Generated gear has "flat tops" on teeth. Solution: Increase the "Number of Segments per Tooth" in the advanced settings. Default is 10; set to 15-20 for smoother curves (increases file size).
Issue: Autodesk Inventor crashes during generation. Solution: Run Inventor as administrator first. Close any open documents before generating.
Most CAD users don't know that the involute curve only exists above the form diameter. Below that, it’s a trochoid (generated by the cutting tool). Geartrax 2021 visually highlights where the "true involute" ends. If you try to put a sensor or bearing seat there, it warns you.
The software does not approximate gear teeth using arcs or splines. It calculates the true involute curve. This level of precision ensures that the 3D model is manufacture-ready, whether you are using 3D printing, CNC hobbing, or wire EDM.
