AlwaysUseChosenToothThicknessForBendingStrength

If this option is selected, the chosen tooth thickness will always be used for bending strength calculations, otherwise the design tooth thickness (zero backlash) will be used when thickness reduction is less than 0.05 m_n.

Declaration
public bool AlwaysUseChosenToothThicknessForBendingStrength { get; set; }
Property Value
Type Description
System.Boolean

ApplyApplicationAndDynamicFactorByDefault

LimitDynamicFactorIfNotInMainResonanceRangeByDefault

If the ISO 6336 Dynamic Factor would give a value greater than 2, and the mesh is not operating in its main resonance range, then this option will clip the dynamic factor to 2.

Declaration

Property Value
Type Description
System.Boolean

LimitMicroGeometryFactorForTheDynamicLoadByDefault

If ISO 6336 Dynamic factor is calculated using Method B for gears ISO tolerance class in the range 1 to 5 as specified in ISO 1328-1:2013(E), then this option will clip the calculated BK to 1.

Declaration
public bool LimitMicroGeometryFactorForTheDynamicLoadByDefault { get; set; }
Property Value
Type Description
System.Boolean

MeanCoefficientOfFrictionFlashTemperatureMethod

Scuffing - Flash Temperature Method. This is the coefficient of friction, as required by the flash temperature method, just before the transition at incipient scuffing. A default value of 0.5 is used as a conservative estimate as suggested in ISO/TS 6336-20:2017 Section 4.3. According to ISO/TS 6336-20:2017, a gear load capacity can be predicted accurately with the coefficient of friction between 0.25 and 0.35, dependent on the lubricant.

UseInterpolatedSinglePairToothContactFactorForHCRHelicalGears

For LCR gears, when the axial contact ratio is above 1, the single pair tooth contact factor will be 1 and for LACR gears, the value is interpolated between 1 and the value for spur gears. For HCR gears (Transverse contact ratio> 2), Section 6.3 applies the calculation of contact stress to the inner point of two pair tooth contact. When interpolating, HCR LACR gears will be interpolated between the value from Section 6.3 and 1. For helical HCR gears with an axial contact ratio above 1 the single pair tooth contact factor will be 1.
