roller-chain-sprocket-10b

Designed and engineered a high-performance industrial roller chain and sprocket drive system tailored for reliable power transmission under heavy cyclic loads. The project focused on precise standard tooth-profile generation, pitch diameter calculations, dynamic assembly fit, and design optimization to minimize friction, tooth wear, and premature fatigue failure. Key Responsibilities & Highlights Standard-Compliant Tooth Geometry: Engineered precise sprocket tooth profiles in accordance with ANSI/ISO standards to ensure smooth roller engagement, low operational noise, and reduced contact stress. Parametric 3D CAD Modeling: Created fully parametric 3D CAD models and kinematic drive assemblies with realistic chain-link wrapping, clearance verifications, and tolerance stack-up analysis. Material Selection & Durability: Specified high-strength alloy steels (such as AISI 1045 / 4140) with induction-hardening recommendations for teeth flanks to maximize wear resistance and fatigue life. Manufacturing Documentation: Generated comprehensive 2D manufacturing drawings featuring GD&T, bore keyway tolerances, hub dimensions, and surface finish callouts ready for CNC machining and hobbing operations.
