Getting Started

After installing the add-in, you can access it directly within Fusion.

 Step-by-Step Guide:

1. Launch Fusion and open your desired project.
2. Navigate to the Create menu.
3. Select HTD3M Pulley Generator to open the generator dialog.

2. Using the Pulley Generator

Pulley Creation

In the generator dialog box, customize your pulley using the following options:

• Number of Teeth: Specify the number of teeth on your pulley.
• Bore Diameter: Enter the diameter of the pulley's central bore.
• Belt Width: Set the width compatible with your 3M HTD belt.
• Flange Thickness: Define the thickness of the flanges on either side of the pulley.
• Fillet Radius (rt): Adjust the fillet radius of the tooth crest (automatically constrained within the 3M standard).

Once parameters are configured, click OK to generate the pulley in your Fusion workspace.

Customization Options Explained

• Number of Teeth: Adjusts pulley diameter and affects gear ratio.
• Bore Diameter: Matches the shaft or axle dimension onto which the pulley fits.
• Belt Width: The width of the belt; this value is internally increased by 1 mm. For example, enter 5 mm if you want a final width of 6 mm.
• Flange Thickness: Helps maintain belt alignment and reduces the risk of belt slip.
• Fillet Radius (rt): Improves tooth strength and belt engagement. The value is constrained to the 3M standard range (0.26 – 0.35mm).

3. Saving and Importing Settings

Exporting Settings:

• Configure your pulley settings.
• Click Export Settings, choose a filename, and save the configuration for future use.

Importing Settings:

• Click Import Settings to reuse saved configurations.
• Locate and select your saved file, then click Open to apply.
