1. What is Vertical Reaction at Bearing 2 Due to Radial Force?

Vertical Reaction at Bearing 2 Due to Radial Force is the vertical reaction force on the 2nd bearing of the crankshaft because of the radial component of thrust force acting on connecting rod. This calculation is essential for proper crankshaft design and bearing selection.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ R2v = \frac{Pr \times b1}{b} \]

Where:

\( R2v \) — Vertical Reaction at Bearing 2 Due to Radial Force (N)
\( Pr \) — Radial Force at Crank Pin (N)
\( b1 \) — Centre Crankshaft Bearing1 Gap from CrankPinCentre (m)
\( b \) — Gap Between Bearing 1&2 of Centre Crankshaft (m)

Explanation: The formula calculates the vertical reaction force at the second bearing based on the radial force at the crank pin and the geometric distances between bearings.

3. Importance of Vertical Reaction Calculation

Details: Accurate calculation of vertical reaction forces is crucial for proper bearing selection, crankshaft design, and ensuring the structural integrity of the engine assembly under maximum torque conditions.

4. Using the Calculator

Tips: Enter radial force at crank pin in Newtons, bearing distances in meters. All values must be positive and non-zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of radial force at crank pin?
A: Radial force at crank pin represents the component of thrust force acting radially on the connecting rod, which is crucial for calculating bearing reactions and stress analysis.

Q2: How are the bearing gaps measured?
A: Bearing gaps are measured as distances along the crankshaft centerline between bearing centers and the crank pin center.

Q3: When is this calculation most important?
A: This calculation is particularly important during maximum torque conditions when bearing loads are at their highest, ensuring proper design and safety margins.

Q4: Are there any limitations to this formula?
A: This formula assumes ideal conditions and may need adjustment for dynamic loads, thermal expansion, and other real-world factors in complex engine designs.

Q5: How does this relate to overall crankshaft design?
A: This calculation is part of the comprehensive stress analysis and bearing load calculations required for robust crankshaft design and engine reliability.
