1. What is the Vertical Reaction on Bearing 1 of Side Crankshaft?

The vertical reaction at bearing 1 due to flywheel weight is the force exerted on the first bearing of the side crankshaft as a result of the flywheel's weight distribution. This calculation is crucial for determining the load distribution and ensuring proper bearing design and selection.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( R'_{1v} \) — Vertical reaction at bearing 1 due to flywheel (N)
• \( W \) — Weight of flywheel (N)
• \( C_2 \) — Side crankshaft bearing 2 gap from flywheel (m)
• \( C \) — Distance between bearing 1 & 2 of side crankshaft (m)

Explanation: The formula calculates the vertical reaction force at the first bearing based on the principle of moments, considering the flywheel weight and the distances between bearings.

3. Importance of Vertical Reaction Calculation

Details: Accurate calculation of vertical reaction forces is essential for proper bearing selection, structural integrity analysis, and ensuring the crankshaft system operates within safe load limits. This helps prevent premature bearing failure and ensures optimal performance.

4. Using the Calculator

Tips: Enter the flywheel weight in Newtons, bearing 2 gap from flywheel in meters, and distance between bearings in meters. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Why is this calculation important for crankshaft design?
A: This calculation helps determine the load distribution on bearings, which is crucial for selecting appropriate bearings and ensuring the crankshaft system can handle the operational loads without failure.

Q2: What units should be used for input values?
A: Weight should be in Newtons (N), and distances should be in meters (m). Ensure consistent units for accurate results.

Q3: How does flywheel position affect the reaction force?
A: The position of the flywheel (represented by C2) directly affects the moment arm and thus the reaction force at bearing 1. A larger C2 increases the reaction force at bearing 1.

Q4: Can this formula be used for other types of shafts?
A: While the principle is similar, this specific formula is designed for side crankshaft configurations with flywheel loading. Other shaft configurations may require different calculations.

Q5: What if there are multiple loads on the crankshaft?
A: For multiple loads, the principle of superposition applies. Each load's effect can be calculated separately and then summed to find the total reaction force at each bearing.
