Nosaukums<p>The formulae specified in this International Standard are intended to establish a uniformly acceptable method for</p> <p>calculating the pitting resistance and bending strength capacity of industrial gears with spur or helical teeth.</p> <p>The rating formulae in this International Standard are not applicable to other types of gear tooth deterioration such</p> <p>as plastic yielding, micropitting, scuffing, case crushing, welding and wear, and are not applicable under vibratory</p> <p>conditions where there may be an unpredictable profile breakdown. The bending strength formulae are applicable</p> <p>to fractures at the tooth fillet, but are not applicable to fractures on the tooth working profile surfaces, failure of the</p> <p>gear rim, or failures of the gear blank through web and hub. This International Standard does not apply to teeth</p> <p>finished by forging or sintering. It is not applicable to gears which have a poor contact pattern.</p> <p>This International Standard provides a method by which different gear designs can be compared.
