Spline Shaft and Bush Coupling Design & Assembly in Solidworks - Full Tutorial

Learn how to model and assemble a Spline Shaft / Bush Coupling in SolidWorks from scratch! This step-by-step tutorial covers both part modeling and assembly, perfect for beginners and mechanical design students. In this video you’ll learn: Part Modeling Commands: • Sketch Command – Create 2D profiles for the shaft and bush • Extruded Boss Command – Build the base 3D geometry • Extruded Cut Command – Add keyways and internal features • Circular Pattern Command – Quickly replicate features around an axis • Circular Sketch Pattern Command – Pattern sketch entities for splines • Fillet Command – Add smooth edges for realism and stress relief • Chamfer Command – Create beveled edges for manufacturing detail Assembly Commands: • Insert Components – Bring parts into the assembly environment • Mate Command – Constrain parts using coincident, concentric, and distance mates • Temporary Axis – Use temporary axes for easy concentric mating of the shaft and bush By the end, you’ll have a fully assembled spline shaft coupling ready for rendering or motion study.
