Naval vessels and large commercial ships use double helical reduction gearboxes to step down turbine or diesel engine speed to propeller shaft speed. The requirement for low underwater radiated noise (UNR) in naval applications and low shipboard noise in commercial vessels drives the helix angle selection and tooth profile quality requirements. At \u03b2 = 30\u00b0, the high contact ratio achieves the acoustic specification without the extreme manufacturing precision of turbine-grade gears. Korea Ever-Power supports classification society documentation requirements for Lloyd’s, DNV, ABS, and KR certification.
