本文件描述了计算外齿圆柱齿轮微点蚀承载能力的程序。该程序是在对油润滑齿轮变速器进行测试和观察的基础上开发的，其模块在3 mm和11 mm之间，节线速度在8 m/s到60 m/s之间。但是，如果满足以下规定的标准，该程序适用于有适当参考数据的任何齿轮副。 规定的公式适用于主动和从动圆柱齿轮，其齿廓符合ISO 53中规定的基本齿条。 它们也适用于虚拟接触比（εαn）小于2,5的与其他基本齿条共轭的齿。对于正常工作压力角高达25°，参考螺旋角高达25°，以及节线速度高于2m/s的情况，结果与其他方法一致。 本文件不适用于评估除微点蚀以外的齿轮齿面损伤类型。

This document describes a procedure for the calculation of the micropitting load capacity of cylindrical gears with external teeth. It has been developed on the basis of testing and observation of oil-lubricated gear transmissions with modules between 3 mm and 11 mm and pitch line velocities of 8 m/s to 60 m/s. However, the procedure is applicable to any gear pair where suitable reference data are available, providing the criteria specified below are satisfied. The formulae specified are applicable for driving as well as for driven cylindrical gears with tooth profiles in line with the basic rack specified in ISO 53. They are also applicable for teeth conjugate to other basic racks where the virtual contact ratio (εαn) is less than 2,5. The results are in good agreement with other methods for normal working pressure angles up to 25°, reference helix angles up to 25° and in cases where pitch line velocity is higher than 2 m/s. This document is not applicable for the assessment of types of gear tooth surface damage other than micropitting.
