Length of Bush on Crank Pin Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Bush on Crank Pin = Force on Crank Pin Bearing/(Inner Diameter of Bush on Crank Pin*Bearing Pressure of CrankPin Bush)
l_c = P_c/(d_cp*p_bc)
This formula uses 4 Variables

Variables Used

Length of Bush on Crank Pin - (Measured in Meter) - Length of bush on crank pin is the length of the bush used in between the crank pin and the crank pin bearing.
Force on Crank Pin Bearing - (Measured in Newton) - Force on crank pin bearing is the force acting onto the bearing used in the assembly of crank pin, crank, and the connecting rod.
Inner Diameter of Bush on Crank Pin - (Measured in Meter) - Inner diameter of bush on crank pin is the internal diameter of the bush used in between the crank pin and the crank pin bearing.
Bearing Pressure of CrankPin Bush - (Measured in Pascal) - Bearing Pressure of CrankPin Bush is the bearing pressure at the crank pin bearing of the big end of the connecting rod.

STEP 1: Convert Input(s) to Base Unit

Force on Crank Pin Bearing: 28800 Newton --> 28800 Newton No Conversion Required
Inner Diameter of Bush on Crank Pin: 50.05892 Millimeter --> 0.05005892 Meter (Check conversion here)
Bearing Pressure of CrankPin Bush: 7.59 Newton per Square Millimeter --> 7590000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

l_c = P_c/(d_cp*p_bc) --> 28800/(0.05005892*7590000)

Evaluating ... ...

l_c = 0.0758000053369521

STEP 3: Convert Result to Output's Unit

0.0758000053369521 Meter -->75.8000053369521 Millimeter (Check conversion here)

FINAL ANSWER

75.8000053369521 ≈ 75.80001 Millimeter <-- Length of Bush on Crank Pin

Connecting Rod

The main function of a connecting rod is to form a link between a piston and crankshaft. A small end of the connecting rod is connected to the piston with a gudgeon pin and the big end is separated into two parts for ease of assembly with a crankpin. The two parts of the big end are the bearing cap and big end housing. Both are being bolted together. This is done for ease of assembly of connecting rod with a crankpin. To supply oil to the big end, the oil hole is drilled from the big end.

Crankshaft

The crankshaft is the final link in the slider-crank mechanism. The linear motion of a piston is converted into the rotary motion of a crankshaft. The energy is generated into the combustion chamber by transforming the reciprocating motion of a piston into the rotary motion of a crankshaft. Crankshaft consists of two main bearings at the other side of it, made up into two half liners. Crankshaft, crankshaft oil seals, main bearings, pulley, and vibration damper are parts of crankshaft assembly.
