Diameter of journal at bearing1 of side crankshaft at TDC position Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diameter of Journal or Shaft at Bearing 1 = Resultant Reaction on CrankShaft Bearing 1/(Length of Bearing1 of Crankshaft*Bearing Pressure of Journal at Bearing 1)
d₁ = R₁/(l₁*P_b)
This formula uses 4 Variables

Variables Used

Diameter of Journal or Shaft at Bearing 1 - (Measured in Meter) - Diameter of Journal or Shaft at Bearing 1 is the inner diameter of the journal or outer diameter of the shaft at the 1st bearing of the crankshaft.
Resultant Reaction on CrankShaft Bearing 1 - (Measured in Newton) - Resultant Reaction on CrankShaft Bearing 1 is the total reaction force on the 1st bearing of the crankshaft.
Length of Bearing1 of Crankshaft - (Measured in Meter) - Length of Bearing1 of Crankshaft is the length of the 1st bearing of a crankshaft and this bearing supports the crankshaft.
Bearing Pressure of Journal at Bearing 1 - (Measured in Pascal) - Bearing pressure of journal at bearing 1 is the compressive stress acting on the contact area between journal and the crankshaft.

STEP 1: Convert Input(s) to Base Unit

Resultant Reaction on CrankShaft Bearing 1: 11000 Newton --> 11000 Newton No Conversion Required
Length of Bearing1 of Crankshaft: 15 Millimeter --> 0.015 Meter (Check conversion here)
Bearing Pressure of Journal at Bearing 1: 12.22222 Newton per Square Millimeter --> 12222220 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d₁ = R₁/(l₁*P_b) --> 11000/(0.015*12222220)

Evaluating ... ...

d₁ = 0.0600000109090929

STEP 3: Convert Result to Output's Unit

0.0600000109090929 Meter -->60.0000109090929 Millimeter (Check conversion here)

FINAL ANSWER

60.0000109090929 ≈ 60.00001 Millimeter <-- Diameter of Journal or Shaft at Bearing 1

Some types of Bearings

1. Deep-Groove Ball Bearings
2. Angular Contact Ball Bearings
3. Self-Aligning Ball Bearings
4. Thrust Ball Bearings
5. Spherical Roller Bearings
6. Cylindrical Roller Bearings
7. Tapered Roller Bearings
8. Needle Roller Bearings

Bearing Strength

In essence, bearing strength is the maximum stress load that the unit can “bear” or hold before the structure fails. But bearing strength can also be measured in terms of tensile, compression, and flexural strength, plus bearing hardness.
