Vertical Reaction at Bearing 2 Due to Flywheel is the vertical reaction force acting on the 2nd bearing of the crankshaft because of the weight of the flywheel. This calculation is important for determining the load distribution and stress analysis in crankshaft design.
The calculator uses the formula:
Where:
Explanation: This formula calculates the vertical reaction force at the second bearing based on the principle of moments and force equilibrium.
Details: Accurate calculation of bearing reactions is crucial for proper crankshaft design, bearing selection, and ensuring the structural integrity of the engine assembly under maximum torque conditions.
Tips: Enter the weight of flywheel in Newtons, the gap distance from bearing 1 to flywheel in meters, and the distance between bearing 1 and 2 in meters. All values must be positive numbers.
Q1: Why is this calculation important for crankshaft design?
A: This calculation helps determine the load distribution on crankshaft bearings, which is essential for proper bearing selection and ensuring the crankshaft can withstand operational stresses.
Q2: What factors affect the vertical reaction at bearing 2?
A: The reaction force is directly proportional to the flywheel weight and the distance from bearing 1 to the flywheel, and inversely proportional to the distance between the two bearings.
Q3: When is maximum torque condition considered?
A: Maximum torque condition is considered during engine design to ensure the crankshaft and bearings can handle the highest loads encountered during operation.
Q4: Are there other reactions that need to be calculated?
A: Yes, horizontal reactions and reactions at other bearings should also be calculated for complete load analysis of the crankshaft system.
Q5: How does flywheel weight affect bearing reactions?
A: Heavier flywheels create larger reaction forces on the bearings, which may require stronger bearings and potentially affect the overall crankshaft design.
