标准范围
This part of ISO 10300 specifies the methods of calculation of the load capacity of bevel gears, theformulae and symbols used for calculation, and the general factors influencing load conditions.The formulae in ISO 10300 (all parts) are intended to establish uniformly acceptable methods forcalculating the pitting resistance and bending strength of straight, helical (skew), spiral bevel, Zerol andhypoid gears. They are applicable equally to tapered depth and uniform depth teeth. Hereinafter, theterm “bevel gear” refers to all of these gear types; if not the case, the specific forms are identified.The formulae take into account the known major factors influencing pitting on the tooth flank andfractures in the tooth root. The rating formulae are not applicable to other types of gear tooth deteriorationsuch as plastic yielding, micropitting, case crushing, welding, and wear. The bending strength formulaeare applicable to fractures at the tooth fillet, but not to those on the active flank surfaces, to failuresof the gear rim or of the gear blank through the web and hub. Pitting resistance and bending strengthrating systems for a particular type of bevel gears can be established by selecting proper values for thefactors used in the general formulae. If necessary, the formulae allow for the inclusion of new factors ata later date. Note, ISO 10300 (all parts) is not applicable to bevel gears which have an inadequate contactpattern under load (see Annex D).The rating system of ISO 10300 (all parts) is based on virtual cylindrical gears and restricted to bevelgears whose virtual cylindrical gears have transverse contact ratios of εvα < 2. Additionally, the givenrelations are valid for bevel gears of which the sum of profile shift coefficients of pinion and wheel iszero (see ISO 23509).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 (all parts) should be confirmed by experience.
