Two-Stage Speed Reducer · 模型 72663
Two-Stage Speed Reducer Project Description: Design of a two-stage gear speed reducer for a naval Bow Thruster. The project focused on managing composite gear ratios to convert high-speed motor input into propeller torque while optimizing for compact dimensions and mechanical efficiency. Development followed Shigley and Norton methodologies using Autodesk Fusion and FTool. Technical Scope: Gear Trains: Dimensioned two pairs of spur gears, optimizing reduction ratios and load distribution across stages to minimize wear. Fatigue Analysis: Evaluated bending strength and contact stress for both stages under intermittent duty cycles. Shaft Engineering: Designed input, intermediate, and output shafts. Conducted deflection analysis and calculated critical speeds to ensure structural integrity under peak torque. Support Systems: Selected rolling-element bearings based on dynamic load ratings and dimensioned shaft-to-hub connections via keys for shear and bearing stress. 3D Modeling: Developed the complete assembly in Autodesk Fusion, performing interference checks and housing optimization for mass reduction.
