Zahnrad mit Inventor erstellen und bemaßen

Introduction

This tutorial will guide you through the process of creating and dimensioning a gear using Autodesk Inventor. By the end of this guide, you will have the skills to design a gear and produce its technical drawing, which can be essential for engineering projects and mechanical design.

Step 1: Start a New Part in Inventor

• Open Autodesk Inventor.
• Select "New" from the file menu.
• Choose the "Part" template to begin designing your gear.

Step 2: Create the Base Sketch

• Start a new 2D sketch on the XY plane.
• Use the circle tool to draw the gear’s base circle, which will determine the gear size.
• Dimension the circle using the dimension tool to specify the diameter.

Step 3: Define the Gear Profile

• Use the polygon tool to create the tooth profile of the gear.
  • Select the number of sides (typically, this will be a circle representing the tooth shape).
• Adjust the size and positioning of the polygon to align with the base circle.

Step 4: Extrude the Gear

• Finish the sketch once the gear profile is defined.
• Go to the "3D Model" tab and select "Extrude."
• Enter the desired thickness for the gear to create a solid 3D model.

Step 5: Create a Drawing from the Gear Model

• Navigate to the "File" menu and select "New" again.
• Choose the "Drawing" template.
• Place the gear model in the drawing sheet for dimensioning.

Step 6: Add Dimensions and Annotations

• Use the dimension tool to add critical measurements to the gear drawing, such as:
  • External diameter
  • Internal hole diameter (if applicable)
  • Tooth height and width
• Include any necessary notes or specifications for clarity.

Step 7: Finalize and Export the Drawing

• Review the drawing for completeness and accuracy.
• Save the drawing file in the appropriate format (e.g., PDF, DWG) for sharing or printing.

Conclusion

In this tutorial, you learned how to create a gear in Autodesk Inventor and produce its technical drawing. These skills are foundational for mechanical design and can be applied in various engineering projects. To further enhance your design skills, consider exploring additional features of Inventor, such as assembly modeling and advanced dimensioning techniques.
