Crank Pin for Different Engines
In a single-cylinder engine, straight engine, or flat engine, each crankpin normally serves just one cylinder. This results in a relatively simple design and it is the cheapest to produce. Most V engines have each pair of cylinders sharing a crankpin. This usually requires an offset between the cylinders in each bank, resulting in a simple connecting rod design. If a cylinder offset is not used, then the connecting rods must be articulated or forked at the big end. Forked connecting rods are mainly used in V-twin motorcycle engines, but in the past were found on a number of automobile and aero engines, such as the Rolls-Royce Merlin aero engine of the WWII era. Radial engines use a more complicated version of articulated connecting rods, where a single "master" connecting rod is attached to the single crankpin (one for each row in multi-row designs), and smaller bearings for each of the corresponding cylinders machined into the big end of the master rod.
How to Calculate Bearing Pressure on Crank Pin Bush?
Bearing Pressure on Crank Pin Bush calculator uses Bearing Pressure of CrankPin Bush = Force on Crank Pin Bearing/(Inner Diameter of Bush on Crank Pin*Length of Bush on Crank Pin) to calculate the Bearing Pressure of CrankPin Bush, Bearing pressure on crank pin bush is the compressive force acting on the contact area between crank pin and the bush having no relative motion between them. Bearing Pressure of CrankPin Bush is denoted by pb symbol.
How to calculate Bearing Pressure on Crank Pin Bush using this online calculator? To use this online calculator for Bearing Pressure on Crank Pin Bush, enter Force on Crank Pin Bearing (Pc), Inner Diameter of Bush on Crank Pin (dcp) & Length of Bush on Crank Pin (lc) and hit the calculate button. Here is how the Bearing Pressure on Crank Pin Bush calculation can be explained with given input values -> 6.8E-6 = 28800/(0.0558*0.0758).
