Flanged Flexible Gear Coupling Hub

Here is a detailed, structured prompt you can use with AI CAD generators (like Text-to-CAD or AI scripting tools in SolidWorks/Fusion 360) or to hand off as a formal design brief to a 3D CAD designer: CAD Modeling Prompt & Design Brief: Standardized 100 mm Flexible Gear Coupling > Role & Objective: > Act as an expert mechanical design engineer. Create a fully parametric 3D CAD model (and parametric assembly) of an industrial Double-Engagement Flanged Flexible Gear Coupling based on ISO 10441 / AGMA standards, designed for a direct-drive heavy-duty conveyor transmission system. > 1. Core Dimensional Specifications > * Shaft Interface (Symmetrical): > * Motor Output Shaft Bore (d_1): 100\text{ mm} (Parallel keyway per ISO/DIN 6885: 28\text{ mm} width \times 16\text{ mm} depth, 125\text{ mm} engagement length). > * Gearbox Input Shaft Bore (d_2): 100\text{ mm} (Parallel keyway per ISO/DIN 6885: 28\text{ mm} width \times 16\text{ mm} depth, 125\text{ mm} engagement length). > * Internal Gear Teeth Parameters: > * Pitch Circle Diameter (D_p): 180\text{ mm}. > * Module (m): 3.0\text{ mm}. > * Number of Teeth (Z): 60 teeth (20^\circ pressure angle, stub tooth profile). > * Hub External Teeth: Crowned geometry with a 250\text{ mm} crowning radius (R_c) for 1.5^\circ angular misalignment capacity. > * Sleeve Face Width (b): 25\text{ mm}. > 2. Assembly & External Geometry Features > * Outer Sleeve & Flange: > * Two symmetrical sleeve halves featuring a central split flange. > * Flange Outer Diameter: 260\text{ mm}. > * Bolt Circle Diameter (BCD): 220\text{ mm}. > * Fastener Pattern: 10\times evenly spaced \text{M12} Grade 8.8 hex bolts with nuts and lock washers. > * Stepped Outer Profile: > * Main Sleeve Body Outer Diameter: 210\text{ mm}. > * Hub Seal Extension Outer Diameter: 150\text{ mm}. > * Smooth stepped transitions with 2\text{ mm} \times 45^\circ chamfers on all outer edges. > 3. Modeling Workflow & Features > * Hubs (Inner Driving & Driven Gears): Revolve a stepped cylindrical body with a 100\text{ mm} central bore and ISO keyway cut. Extrude/cut the 60 external crowned gear teeth on the outer perimeter (D_p = 180\text{ mm}). > * Outer Sleeve Halves: Revolve the outer casing with a outer bolt flange. Internal bore cut with matching 60 internal spur gear teeth to mesh with the hub. > * Flange Bolting Array: Create a circular pattern of 10 clearance holes (\varnothing 13.5\text{ mm}) on the 220\text{ mm} BCD. > * Assembly Alignment: Mate the two inner hubs onto their respective 100\text{ mm} shafts. Mate the sleeve halves over the hubs and align the central flanges face-to-face with concentric bolt hole alignment. >
