The formula to calculate the Equivalent Dynamic Load (P) is:
\[
P = X \cdot Fr + Y \cdot Fa
\]
Where:
P – The equivalent dynamic load in kilonewtons (kN).
X – The radial load factor.
Fr – The radial bearing load in kilonewtons (kN).
Y – The axial load factor.
Fa – The axial bearing load in kilonewtons (kN).
Definition
Equivalent Dynamic Load (P): The combined effect of the static load and the centrifugal force in a bearing.
Radial Load Factor (X): A factor that accounts for the radial load on the bearing.
Radial Bearing Load (Fr): The load acting radially on the bearing.
Axial Load Factor (Y): A factor that accounts for the axial load on the bearing.
Axial Bearing Load (Fa): The load acting axially on the bearing.
Example
Let's say the radial load factor (X) is 0.56, the radial bearing load (Fr) is 5 kN, the axial load factor (Y) is 1.2, and the axial bearing load (Fa) is 3 kN. Using the formula:
