Helical Gear Units

A Comparison of Current AGMA, ISO and API Gear Rating …

Specification for High-Speed Helical Gear Units. The first high-speed gear unit standard was adopted in 1943 and has evolved over time. It is now based on ANSI/AGMA 2001-D04 and applies when the pitch line velocity exceeds 6,890ft/min (35 m/s). The factors to be used for rating are either specified or a specific calculation procedure is given.
