Diff. Gear Part 4. that Comes With Its Own Splined Shaft (Here's Why That Matters)

Learn how to design a differential pinion gear in SolidWorks — Part 4 of my full differential gearbox build, continuing on from the housing, flange, and shaft in Parts 1 through 3. Watch Part 1 (Differential Housing) here:    • Design a Differential Gearbox Housing in S...   Watch Part 2 (Differential Flange) here:    • Design a Differential Flange in SolidWorks...   Watch Part 3 (Splined Shaft) here:    • Differential Gearbox Pt  3 -  (The One Par...   In this video, I walk through the process of modeling the pinion: ✅ Model the splined shaft section on one end ✅ Build the bevel gear on the opposite end ✅ Blend the shaft and gear into one continuous part ✅ Fillet the transition between the shaft and the gear body This is the piece that actually drives the ring gear inside the housing from Part 1, so its bevel angle and spline size have to match up with the rest of the build, not just look correct on their own. ⏱️ Chapters 00:00 Final Part Preview 00:10 Starting from the existing bevel gear 00:40 Building the shaft from behind the gear 02:00 Cutting and patterning the splines 06:30 Fillets and final cleanup 🔧 Commands used: Extrude Boss/Base, Extruded Cut, Circular Pattern, Fillet 📌 Subscribe to Learn CAD with Billu to follow the rest of the differential gearbox build. #SolidWorks #CADTutorial #MechanicalEngineering #Projects
