1. What is the Axial Thrust Load Calculation?

The axial thrust load calculation determines the amount of thrust load acting axially on a spherical roller bearing when the ratio of axial to radial load (Fa/Fr) is greater than the eccentricity factor (e). This is crucial for proper bearing selection and performance analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Fa = \frac{Peq_{sp} - (0.67 \times Fr)}{Y2} \]

Where:

\( Fa \) — Axial or thrust load acting on bearing (N)
\( Peq_{sp} \) — Equivalent dynamic load on spherical bearing (N)
\( Fr \) — Radial load acting on bearing (N)
\( Y2 \) — Factor Y2 of the bearing

Explanation: This formula calculates the axial thrust load by subtracting a portion of the radial load (67%) from the equivalent dynamic load and dividing by the bearing's Y2 factor.

3. Importance of Axial Thrust Load Calculation

Details: Accurate axial thrust load calculation is essential for proper bearing selection, ensuring optimal performance, preventing premature failure, and maintaining system reliability in mechanical applications.

4. Using the Calculator

Tips: Enter equivalent dynamic load in Newtons, radial load in Newtons, and the Y2 factor of the bearing. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: When is this calculation applicable?
A: This calculation is specifically used when the ratio of axial to radial load (Fa/Fr) is greater than the eccentricity factor (e) of the bearing.

Q2: What is Factor Y2 in bearing calculations?
A: Factor Y2 is a bearing-specific constant used in the calculation of equivalent dynamic load for bearings, representing the bearing's axial load capacity.

Q3: Why is 67% of radial load subtracted?
A: The 0.67 factor accounts for the portion of radial load that contributes to the equivalent dynamic load calculation in this specific scenario.

Q4: What are typical Y2 values for spherical roller bearings?
A: Y2 values typically range from 1.8 to 3.5 depending on the specific bearing design and manufacturer specifications.

Q5: How does this affect bearing life calculation?
A: Accurate axial load calculation directly impacts the equivalent dynamic load, which is used to calculate bearing life using the L10 life formula.
