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 a critical dimension in crankshaft design that affects the structural integrity and performance of the engine.
The calculator uses the formula:
Where:
Explanation: This formula provides a direct relationship between the thickness and width of the crank web, where the width is approximately 1.6285 times the thickness.
Details: Accurate calculation of crank web width is crucial for ensuring proper stress distribution, fatigue resistance, and overall structural stability of the crankshaft. Proper dimensions help prevent mechanical failures and extend the lifespan of engine components.
Tips: Enter the thickness of the crank web in meters. The value must be a positive number greater than zero. The calculator will automatically compute the corresponding width based on the established formula.
Q1: Why is the width calculated as 1.6285 times the thickness?
A: This ratio is derived from engineering standards and empirical data to ensure optimal mechanical performance and stress distribution in crankshaft design.
Q2: What units should be used for input values?
A: The calculator uses meters for both input and output values to maintain consistency with engineering standards.
Q3: Can this formula be used for all types of crankshafts?
A: This formula is specifically designed for centre crankshafts at TDC position. Different crankshaft configurations may require different calculation methods.
Q4: How accurate is this calculation method?
A: The formula provides a standard engineering approximation. For critical applications, additional finite element analysis and testing may be required.
Q5: What factors influence the choice of crank web dimensions?
A: Engine load requirements, material properties, operating conditions, and safety factors all influence the optimal dimensions of crank web components.
