1 Scope This part of ISO 10300 specifies the basic formulae for use in the determination of the surface load capacity of straight and helical (skew), Zerol and spiral bevel gears including hypoid gears, and comprises all the influences on surface durability for which quantitative assessments can be made. This part of ISO 10300 is applicable to oil lubricated bevel gears, as long as sufficient lubricant is present in the mesh at all times. The formulae in this part of ISO 10300 are based on virtual cylindrical gears and restricted to bevel gears whose virtual cylindrical gears have transverse contact ratios of ε vα < 2. The results are valid within the range of the applied factors as specified in ISO 10300-1 (see ISO 6336-2 [ 1 ] ). Additionally, the given relations are valid for bevel gears of which the sum of profile shift coefficients of pinion and wheel is zero (see ISO 23509). The formulae in this part of ISO 10300 are not directly applicable to the assessment of other types of gear tooth surface damage, such as plastic yielding, scratching, scuffing or any other type not specified.
WARNING The user is cautioned that when the formulae are used for large average mean spiral angles ( β m1 + β m2 )/2 > 45°, for effective pressure angles α e > 30° and/or for large face widths b > 13 m mn , the calculated results of ISO 10300 should be confirmed by experience.
