GB/T 19406-2003 — This standard specifies: strength and flexural strength check calculation method of industrial contacts with straight and helical gears, this standard the formula does not apply to other forms tooth damage, such as plastic deformation, micro- pitting, gluing, surface crushing, welding and wear, can not be applied to unexpected tooth profile destroy under vibration conditions.

Flexural strength formula can be applied to the tooth root root fillet break, rather than using tooth profile on the tooth surface work broken gear ring failure or gear blank spokes and wheels failure.

This standard does not apply to forging or became final processing methods tooth, then angle can not be applied to spot poor gear.

What this standard covers

This standard specifies: strength and flexural strength check calculation method of industrial contacts with straight and helical gears, this standard the formula does not apply to other forms tooth damage, such as plastic deformation, micro- pitting, gluing, surface crushing, welding and wear, can not be applied to unexpected tooth profile destroy under vibration conditions. Flexural strength formula can be applied to the tooth root root fillet break, rather than using tooth profile on the tooth surface work broken gear ring failure or gear blank spokes and wheels failure. This standard does not apply to forging or became final processing methods tooth, then angle can not be applied to spot poor gear. This standard specifies a different gear design comparison method, their purpose to ensure that the assembly does not drive gear system performance, nor for general engineering use, but for experienced designer gear used, him based on a similar design knowledge and discussed on the impact of these chapters understanding, energy for these formulas coefficient reasonable choice value.
