A twin-screw gearbox is required for continuous-duty industrial machinery. I need a complete mechanical design that can withstand heavy cyclic loads and operate reliably on a 24/7 production line. While the exact host machine will be shared after project start, think of a high-throughput environment where durability and serviceability matter more than compactness. Your task spans concept through production-ready documentation. That includes sizing and selecting gears, shafts, bearings, seals, and lubrication; producing a robust housing that keeps alignment tight under load; and predicting performance so we can validate torque capacity, efficiency, and noise levels before committing to steel. I am open to design choices—as long as the solution can be tuned later for higher torque, higher efficiency, or quieter operation without forcing a complete redesign. Deliverables • 3D CAD model (SolidWorks, Inventor, or comparable neutral format) • Detailed manufacturing drawings with tolerances, surface finishes, and material specs • Bill of materials and consumables list • Basic FEA or AGMA/ISO calculations demonstrating factor of safety and service life • Assembly & maintenance guide, including lubricant type and change intervals Files must be organised clearly so my machine shop can quote and the maintenance crew can service the unit without lengthy explanations. Let me know the software versions you’ll be using and the standards you plan to reference when you submit your proposal.

Hello, Your project is exactly the type of engineering work I enjoy. I understand that this gearbox is intended for continuous industrial operation, where reliability, durability, and ease of maintenance are more important than minimizing size. I can design a complete twin-screw gearbox from concept to production-ready documentation. The design will include properly sized gears, shafts, bearings, seals, lubrication system, and a rigid housing that maintains alignment under heavy cyclic loads. Throughout the design process, I'll focus on achieving a solution that is efficient, serviceable, and can be upgraded in the future for higher torque or quieter operation without requiring a complete redesign. You'll receive a fully organized project package, including 3D CAD models (SolidWorks 2024 and STEP format), detailed manufacturing drawings with tolerances and material specifications, a complete Bill of Materials, engineering calculations with basic FEA/AGMA validation, and an assembly and maintenance guide with lubrication recommendations. I believe in keeping communication simple and transparent, and I'm happy to discuss design decisions throughout the project to ensure the final product meets your expectations. I'm looking forward to learning more about your application and contributing to a reliable, production-ready gearbox design. Best regards, Sumit Kumar Mechanical CAD Engineer | SolidWorks | CAD/CAM | Design for Manufacturing
