This formula uses 1 Functions, 5 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Pitch Line Velocity - The Pitch Line Velocity is defined as the product of the constant pi, the diameter of the pitch circle, and the angular velocity. (Measured in Meter per Second)
Deformation factor - The Deformation factor is defined as the ratio of the form of tooth factor to the sum of the inverse of modulus of elasticity of pinion and inverse of modulus of elasticity of fear. (Measured in Newton per Square Millimeter)
Error - Error can be defined as gears on small-diameter shaft easily twist through an angle equivalent to the effective tooth error and the dynamic load is reduced. e = ep + eg. (Measured in Millimeter)
Face width - Face width is the length of the tooth parallel to the gear axis. (Measured in Millimeter)
Tangential force - Tangential force due to rated torque is ratio of the rated torque upon the radius of the gear or pinion. (Measured in Newton)

## What is dynamic load ?

The dynamic load or additional load due to dynamic conditions between two meshing teeth. Buckingham has used a term ‘incremental dynamic load’ for (Pd). It is used to calculate the effective load in the gera geometry.

## How to Calculate Dynamic load?

Dynamic load calculator uses Dynamic_load = ((21*Pitch Line Velocity)*((Deformation factor*Error*Face width)+(Tangential force)))/((21*Pitch Line Velocity)+sqrt((Deformation factor*Error*Face width)+(Tangential force))) to calculate the Dynamic load, The dynamic load is the additional load due to the dynamic condiitons associated between the two meshing teeth. Dynamic load is denoted by Pd symbol.

How to calculate Dynamic load using this online calculator? To use this online calculator for Dynamic load, enter Pitch Line Velocity (v), Deformation factor (C), Error (esum), Face width (b) & Tangential force (Pt) and hit the calculate button. Here is how the Dynamic load calculation can be explained with given input values -> 1088.313 = ((21*2.5)*((10000000*5E-05*0.04)+(2000)))/((21*2.5)+sqrt((10000000*5E-05*0.04)+(2000))).

### FAQ

The dynamic load is the additional load due to the dynamic condiitons associated between the two meshing teeth and is represented as Pd = ((21*v)*((C*esum*b)+(Pt)))/((21*v)+sqrt((C*esum*b)+(Pt))) or Dynamic_load = ((21*Pitch Line Velocity)*((Deformation factor*Error*Face width)+(Tangential force)))/((21*Pitch Line Velocity)+sqrt((Deformation factor*Error*Face width)+(Tangential force))). The Pitch Line Velocity is defined as the product of the constant pi, the diameter of the pitch circle, and the angular velocity, The Deformation factor is defined as the ratio of the form of tooth factor to the sum of the inverse of modulus of elasticity of pinion and inverse of modulus of elasticity of fear, Error can be defined as gears on small-diameter shaft easily twist through an angle equivalent to the effective tooth error and the dynamic load is reduced. e = ep + eg, Face width is the length of the tooth parallel to the gear axis & Tangential force due to rated torque is ratio of the rated torque upon the radius of the gear or pinion.
The dynamic load is the additional load due to the dynamic condiitons associated between the two meshing teeth is calculated using Dynamic_load = ((21*Pitch Line Velocity)*((Deformation factor*Error*Face width)+(Tangential force)))/((21*Pitch Line Velocity)+sqrt((Deformation factor*Error*Face width)+(Tangential force))). To calculate Dynamic load, you need Pitch Line Velocity (v), Deformation factor (C), Error (esum), Face width (b) & Tangential force (Pt). With our tool, you need to enter the respective value for Pitch Line Velocity, Deformation factor, Error, Face width & Tangential force and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
