This part of ISO 10300 specifies the basic formulae for use in the determination of the surface loadcapacity of straight and helical (skew), Zerol and spiral bevel gears including hypoid gears, and comprisesall the influences on surface durability for which quantitative assessments can be made. This part ofISO 10300 is applicable to oil lubricated bevel gears, as long as sufficient lubricant is present in the meshat all times.The formulae in this part of ISO 10300 are based on virtual cylindrical gears and restricted to bevelgears whose virtual cylindrical gears have transverse contact ratios of εvα < 2. The results are validwithin the range of the applied factors as specified in ISO 10300-1 (see ISO 6336-2[1]). Additionally, thegiven relations are valid for bevel gears of which the sum of profile shift coefficients of pinion and wheelis zero (see ISO 23509).The formulae in this part of ISO 10300 are not directly applicable to the assessment of other types ofgear 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 spiralangles (βm1+βm2)/2 > 45°, for effective pressure angles αe > 30° and/or for large face widthsb > 13 mmn, the calculated results of ISO 10300 should be confirmed by experience.
