1. What is the Gap of Bearing 3 from Flywheel?

The Gap of Bearing 3 from Flywheel is the distance between the 3rd bearing of a centre crankshaft and the line of action of flywheel weight. This measurement is crucial for proper crankshaft alignment and load distribution in engine design.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ c2 = \frac{Rv2 \times c}{W} \]

Where:

\( c2 \) — Centre Crankshaft Bearing3 Gap from Flywheel (m)
\( Rv2 \) — Vertical Reaction at Bearing 2 due to Flywheel (N)
\( c \) — Gap Between Bearing 2&3 of Centre Crankshaft (m)
\( W \) — Weight of Flywheel (N)

Explanation: This formula calculates the distance from the third bearing to the flywheel based on the vertical reaction force at the second bearing, the distance between bearings, and the flywheel weight.

3. Importance of Bearing Gap Calculation

Details: Accurate bearing gap calculation is essential for proper crankshaft alignment, reducing vibration, preventing premature bearing wear, and ensuring optimal engine performance and longevity.

4. Using the Calculator

Tips: Enter the vertical reaction force in Newtons, the gap between bearings in meters, and the flywheel weight in Newtons. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is the bearing gap important in crankshaft design?
A: Proper bearing gap ensures even load distribution, reduces stress concentrations, and prevents premature bearing failure in the crankshaft assembly.

Q2: What factors affect the vertical reaction at bearing 2?
A: The vertical reaction is influenced by flywheel weight, engine torque, rotational forces, and the overall crankshaft geometry and alignment.

Q3: How does flywheel weight impact bearing loads?
A: Heavier flywheels create higher bearing reactions and require more precise gap calculations to maintain proper load distribution and alignment.

Q4: When should this calculation be performed?
A: This calculation should be done during engine design, crankshaft modification, or when replacing bearings to ensure proper fitment and alignment.

Q5: Are there limitations to this formula?
A: This formula provides a basic calculation and may need adjustments for complex loading conditions, dynamic forces, or non-standard crankshaft configurations.
