The prompt
Create a highly detailed, mechanically realistic 3D CAD model of an industrial Coiled Tubing Injector Head used in oil and gas well intervention operations. The model must represent a real coiled tubing injector, not a conventional fuel injector or injection molding machine. Design the complete mechanical assembly, including: 1. Main structural steel frame and mounting base. 2. Two opposing continuous gripper chain assemblies. 3. Individual gripper blocks mounted on the chains. 4. Chain links, rollers, pins, bushings, and retaining rings. 5. Hydraulic chain tensioning cylinders. 6. Hydraulic drive motors. 7. Planetary reduction gearboxes. 8. Drive sprockets and idler sprockets. 9. Tubing guide rollers and entry guide. 10. Front and rear chain guide housings. 11. Hydraulic hoses, fittings, and mounting brackets. 12. Coiled tubing passing centrally through the injector. MECHANICAL REQUIREMENTS: - The tubing must pass through the center of the injector. - The two opposing gripper chains must contact and grip the tubing symmetrically. - The chain assemblies must be mechanically connected to drive sprockets and tensioning mechanisms. - The assembly must resemble an actual industrial oilfield injector head. - Use realistic industrial proportions, mechanical clearances, fasteners, bearings, and machined surfaces. - Avoid decorative or fictional components. CAD OUTPUT REQUIREMENTS: - Create a complete parametric assembly. - Every major component must be a separate part. - Include an exploded assembly configuration. - Include front, side, top, and sectional views. - Generate an assembly tree and bill of materials. - Export the assembly as STEP AP242. - Export individual parts as STEP files. - Provide native CAD files if supported. Use a realistic industrial engineering style inspired by NOV Hydra Rig coiled tubing injector designs. Important: This is a conceptual engineering model. Do not invent certified dimensions or claim that the model is suitable for manufacturing without engineering verification.
