Eccentricity Ratio in Terms of Minimum Film Thickness of Bearing Solution

STEP 0: Pre-Calculation Summary

Formula Used

Eccentricity Ratio of Journal Bearing = 1-(Minimum Film Thickness/Radial clearance for bearing)
ε = 1-(h_°/c)
This formula uses 3 Variables

Variables Used

Eccentricity Ratio of Journal Bearing - Eccentricity Ratio of Journal Bearing is the ratio of the eccentricity of the journal bearing's inner race to the radial clearance.
Minimum Film Thickness - (Measured in Meter) - Minimum film thickness is the lowest amount of the thickness of the oil film formed inside the sliding bearing.
Radial clearance for bearing - (Measured in Meter) - Radial clearance for bearing is a measured value of the total movement of one ring relative to the other in a plane perpendicular to the bearing axis.

STEP 1: Convert Input(s) to Base Unit

Minimum Film Thickness: 0.013 Millimeter --> 1.3E-05 Meter (Check conversion here)
Radial clearance for bearing: 0.024 Millimeter --> 2.4E-05 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ε = 1-(h_°/c) --> 1-(1.3E-05/2.4E-05)

Evaluating ... ...

ε = 0.458333333333333

STEP 3: Convert Result to Output's Unit

0.458333333333333 --> No Conversion Required

FINAL ANSWER

0.458333333333333 ≈ 0.458333 <-- Eccentricity Ratio of Journal Bearing
