Minimum length of crankpin given crankpin diameter Solution

STEP 0: Pre-Calculation Summary
Formula Used
Length of Crank Pin = 0.6*Diameter of Crank Pin
lc = 0.6*dcp
This formula uses 2 Variables
Variables Used
Length of Crank Pin - (Measured in Meter) - Length of Crank Pin is the size of the crankpin from one end to the other and tells how long is the crankpin.
Diameter of Crank Pin - (Measured in Meter) - Diameter of crank pin is the diameter of the crank pin used in connecting the connecting rod with the crank.
STEP 1: Convert Input(s) to Base Unit
Diameter of Crank Pin: 48 Millimeter --> 0.048 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
lc = 0.6*dcp --> 0.6*0.048
Evaluating ... ...
lc = 0.0288
STEP 3: Convert Result to Output's Unit
0.0288 Meter -->28.8 Millimeter (Check conversion here)
FINAL ANSWER
28.8 Millimeter <-- Length of Crank Pin
(Calculation completed in 00.020 seconds)

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 Minimum length of crankpin given crankpin diameter?

Minimum length of crankpin given crankpin diameter calculator uses Length of Crank Pin = 0.6*Diameter of Crank Pin to calculate the Length of Crank Pin, Minimum length of crankpin given crankpin diameter is the minimum required length of the crankpin of a crank and connecting rod assembly.
