Width of Crank Web is defined as the width of the crank web (the portion of a crank between the crankpin and the shaft) measured perpendicular to the crankpin longitudinal axis. It is an important parameter in crankshaft design and analysis.
The calculator uses the formula:
Where:
Explanation: The formula provides a proportional relationship between the crank pin diameter and the required width of the crank web for proper mechanical strength and stability.
Details: Accurate calculation of crank web width is crucial for ensuring the structural integrity of the crankshaft, proper load distribution, and preventing mechanical failures in engine operation.
Tips: Enter the diameter of crank pin in meters. The value must be valid (diameter > 0).
Q1: Why is the factor 1.14 used in the formula?
A: The factor 1.14 is derived from empirical data and engineering standards to ensure adequate strength and stability of the crank web relative to the crank pin diameter.
Q2: What are typical values for crank pin diameter?
A: Crank pin diameter varies depending on engine size and application, typically ranging from 0.03m to 0.15m for automotive engines.
Q3: Does this formula apply to all types of crankshafts?
A: This formula is specifically designed for centre crankshafts at TDC position. Other crankshaft configurations may require different calculation methods.
Q4: What units should be used for input values?
A: The calculator uses meters for both input and output. Ensure consistent unit usage for accurate results.
Q5: Are there other factors that affect crank web design?
A: Yes, additional factors include material properties, operating loads, safety factors, and specific application requirements that may influence the final design.
