The Horizontal Bending Moment in Shaft Under Flywheel is the bending moment in the horizontal plane of the part of the crankshaft under the flywheel. It represents the rotational force effect caused by belt tensions acting on the crankshaft bearing.
The calculator uses the formula:
Where:
Explanation: The horizontal bending moment is calculated by multiplying the horizontal reaction force at the first bearing by the distance from the flywheel center.
Details: Accurate calculation of horizontal bending moment is crucial for crankshaft design and analysis, ensuring structural integrity and proper functioning of the engine system under various load conditions.
Tips: Enter the horizontal reaction force in Newtons and the bearing gap distance in meters. Both values must be positive numbers greater than zero.
Q1: What causes horizontal reaction at bearing 1?
A: The horizontal reaction is primarily caused by belt tensions acting on the crankshaft pulley system.
Q2: How is bearing gap from flywheel measured?
A: The bearing gap is measured as the distance from the center of the first bearing to the line of application of flywheel weight or flywheel center.
Q3: Why is horizontal bending moment important in crankshaft design?
A: It helps determine the stress distribution and ensures the crankshaft can withstand the bending forces without failure.
Q4: What units should be used for input values?
A: Force should be in Newtons (N) and distance in meters (m) for consistent SI unit results.
Q5: Can this calculator be used for other types of shafts?
A: While specifically designed for crankshafts, the same principle can be applied to other shaft systems with similar loading conditions.
