ISO 10300-3:20 14规定了用于直齿和螺旋（斜齿）、零齿和螺旋锥齿轮（包括准双曲面齿轮）齿根应力计算的基本公式，齿根下的最小轮辋厚度为3.5 mmN。所有载荷对齿根应力的影响都包括在内，只要它们是齿轮传递的载荷的结果并且能够定量评估。在计算齿根应力σ f或允许齿根应力σ fp时，应考虑由齿轮轮辋的收缩配合引起的应力，这些应力叠加在齿载荷引起的应力上。ISO 10300-3:20 14不适用于评估所谓的齿面断裂，即牙齿内部疲劳断裂（TIFF）。ISO 10300-3:20 14中的公式基于虚拟圆柱齿轮，仅限于虚拟圆柱齿轮横向接触比为？V α<2。结果在ISO 10300-1（另见ISO 6336-3）规定的应用因子范围内有效。此外，给定的关系对于锥齿轮有效，其中小齿轮和车轮的轮廓变速系数之和为零（参见ISO 23509）。
ISO 10300-3:2014 specifies the fundamental formulae for use in the tooth root stress calculation of straight and helical (skew), Zerol and spiral bevel gears including hypoid gears, with a minimum rim thickness under the root of 3,5 mmn. All load influences on tooth root stress are included, insofar as they are the result of load transmitted by the gearing and able to be evaluated quantitatively. Stresses, such as those caused by the shrink fitting of gear rims, which are superposed on stresses due to tooth loading, are intended to be considered in the calculation of the tooth root stress, σF, or the permissible tooth root stress σFP. ISO 10300-3:2014 is not applicable in the assessment of the so-called flank breakage, a tooth internal fatigue fracture (TIFF).The formulae in ISO 10300-3:2014 are based on virtual cylindrical gears and restricted to bevel gears whose virtual cylindrical gears have transverse contact ratios of ？vα < 2. The results are valid within the range of the applied factors as specified in ISO 10300-1 (see also ISO 6336-3). Additionally, the given relationships are valid for bevel gears, of which the sum of profile shift coefficients of pinion and wheel is zero (see ISO 23509).
