What is addendum Dedendum?
DEDENDUM Addendum is the height of the tooth above the pitch circle. Dedendum is the depth of the tooth below the pitch circle. Whole Depth is the total length of a tooth space equal to the sum of the addendum and dedendum.
How is addendum and Dedendum measured?
With the movement of teeth profile, now we have:
- addendum ha=(1+x)*m.
- dedendum hf=(1.25-x)*m.
Are addendum and Dedendum equal?
Explanation: WHOLE DEPTH is the total depth of a tooth space, equal to addendum plus dedendum, equal to the working depth plus variance. WORKING DEPTH is the depth of engagement of two gears; that is, the sum of their addendums.
Why is Dedendum value more than addendum?
Why dedendum Value is more than addendum value? In order to get clearance between the teeth of one gear and bottom surface of mating gear so as to avoid interference, dedendum is having more value than addendum.
What is Dedendum circle?
Definition of dedendum circle : the circle touching the bottom of the spaces between the teeth of a gear wheel.
How is DP of gear calculated?
Gear Spur Tooth Strength Equation and Calculator….Spur Gear Design Calculator.
| To Find | Equation |
|---|---|
| Pitch Diameter | D = N / P D = (N p ) / π |
| Root Diameter | DR = D – 2b |
| Whole Depth | a + b |
| Working Depth | aG + ap |
What is working depth of a gear tooth?
Working depth: This is the distance of the engagement of two mating teeth and is equal to the sum of the addendum of the mating teeth of the two gears. It is the radial distance from the addendum circle to the clearance circle. Hence if both the gear were identical then, Working depth = 2 × addendum.
What is the velocity ratio of worm gears?
Explanation: Velocity ratio in worm gears is given as the ratio of the angle turned by the gear to the angle turned by the worm. Thus, velocity ratio = (2l/d2)/(2π) = l/(πd2).
