The formulae specified in this International Standard are intended for the establishment of a uniformly acceptable<\/p>\n
method for calculating the pitting resistance and bending strength capacity for the endurance of the mainpropulsion<\/p>\n
and auxiliary gears of ships, offshore vessels and drilling rigs, having straight or helical teeth and subject<\/p>\n
to the rules of classification societies.<\/p>\n
The rating formulae in this International Standard are not applicable to other types of gear tooth deterioration, such<\/p>\n
as plastic yielding, micropitting, scuffing, case crushing, welding and wear, and are not applicable under vibratory<\/p>\n
conditions where there may be an unpredictable profile breakdown. The bending strength formulae are applicable<\/p>\n
to fractures at the tooth fillet, but are not applicable to fractures on the tooth working profile surfaces, failure of the<\/p>\n
gear rim, or failures of the gear blank through web and hub. This International Standard does not apply to teeth<\/p>\n
finished by forging or sintering. This standard is not applicable to gears having a poor contact pattern.<\/p>\n
This International Standard provides a method by which different gear designs can be compared. It is not intended<\/p>\n
to assure the performance of assembled drive gear systems. It is not intended for use by the general engineering<\/p>\n
public. Instead, it is intended for use by the experienced gear designer who is capable of selecting reasonable<\/p>\n
values for the factors in these formulae based on knowledge of similar designs and awareness of the effects of the<\/p>\n
items discussed.<\/p>\n
WARNING \u2014 The user is cautioned that the calculated results of this International Standard should be<\/b><\/p>\n
confirmed by experience.<\/b><\/p>\n","protected":false},"excerpt":{"rendered":"
