ABENICS Maker

Fusion360 Plugin to create ABENICS. Blue gear and red one are CS-Gear and MP-Gear, respectively.

This script is derived from SpurGear.py which is a sample script written by Brian Ekins. Kazuki Abe, Kenjiro Tadakuma and Riichiro Tadakuma develop ABENICS and have a presentation on YouTube. ABENICS system is patent pending. You have to pay attention to create and use the gears and application.

Usage

Clone this project in your environment.

git clone https://github.com/botamochi6277/ABENICS-Maker.git

Run Fusion360 and open Scripts and Add Ins tab. Add ABENICS.py to My Scripts with pushing "+" icon. When you have some troubles to adding, visit the official instruction page.

Input parameters and run. You can get gears of ABENICS.

Parameters

• Pressure Angle : pressure angle of teeth. It is usually 20 deg.
• Module : module of a gear sketch. it is size of a tooth.
• Backlash : Backlash of the gear. It shrinks the cs-gear sketch and enlarges the sh-cutter sketch.
• Gear Thickness: Thickness of MP-Gear
• Hole Diameter: Hole diameter of MP-Gear
• Num. of teeth of CS-Gear: the number of teeth of CS-Gear
• Gear Ratio: Gear Ratio of CS-Gear/MP-Gear
• Num. of rotation steps: the number of rotation steps for engraving MP-Gear. When it is 36 steps, MP-Gear rotates by 10deg in every step.

What this code does

This code runs according to the ABENICS Paper. The following list may you help to customize the script

1. Draw a half gear sketch of a SH-Cutter
2. Revolve the sketch profile to make a SH-Cutter body
3. Draw a ring sketch for a MP-Gear
4. Extrude the sketch profiles to make a MP-Gear body
5. Engrave and rotate the MP-Gear with SH-Cutter
6. Remove SH-Cutter
7. Draw a half gear sketch of a CS-gear
8. Revolve the sketch profile to make a CS-Gear body
9. Draw another half gear sketch of CS-gear for intersection
10. Revolve the sketch profile to intersect the CS-Gear body
