Aim: Gear designed with current standards and right dimensions.
This is one of entry level projects I have made at my university. First picture below shows the input data. It has been scanned and reworked in Adobe Photoshop. Tooth diameter allowed to set base refference section. Measurements have been compared to standards and construction rules. Cooperating elements like bearings, seals or shaft connectors were drawn first. All drawings were made with Autodesk AutoCAD. I have completed 30+ similar projects since 2015.
