Read More →This article analyzes small crankshaft manufacturing for reciprocating compressors. These core components endure alternating loads over 200 MPa, speeds to 3000 r/min, thin oil film, and -20 to 80°C temperatures. Material choice prioritizes 40CrNi2MoA for fatigue strength, with 42CrMo as economic alternative. Process includes die forging (ratio >=3), quenching/tempering to 28-34 HRC core, surface hardening to 54-58 HRC, and precision machining to IT7, Ra <=0.4 μm. Quality control covers dimensions, hardness, MPI, UT, with three-level inspection. Failure prevention targets fatigue, wear, cracking, and imbalance. A case study achieved 99.5% yield. Cost breakdown shows machining as largest share; batch optimization and near-net-shape forging reduce costs. Trends include laser hardening, 3D repair, in-process sensing, composites, and green quenchants. Zero-defect production integrates materials, heat treatment, precision machining, and quality management for reliable compressor operation.
