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

Vertical Reaction at Bearing 1 Due to Radial Force is the vertical reaction force on the 1st bearing of the crankshaft because of the radial component of thrust force acting on connecting rod. This force is crucial for determining the load distribution and stress analysis in crankshaft design.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ R1v = \frac{Pr \times b2}{b} \]

Where:

\( R1v \) — Vertical Reaction at Bearing 1 Due to Radial Force (N)
\( Pr \) — Radial Force at Crank Pin (N)
\( b2 \) — Centre Crankshaft Bearing2 Gap from CrankPinCentre (m)
\( b \) — Gap Between Bearing 1&2 of Centre Crankshaft (m)

Explanation: The formula calculates the vertical reaction force at bearing 1 based on the principle of moments and force equilibrium in the crankshaft system.

3. Importance of Vertical Reaction Calculation

Details: Accurate calculation of vertical reaction forces is essential for proper bearing selection, fatigue analysis, and ensuring the structural integrity of the crankshaft under maximum torque conditions.

4. Using the Calculator

Tips: Enter radial force at crank pin in Newtons, bearing gaps 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 the connecting rod force that acts perpendicular to the crank radius, creating bending moments in the crankshaft.

Q2: How does bearing gap affect the reaction force?
A: The relative distances between bearings (b2 and b) determine how the radial force is distributed between the two bearings, following the principle of moments.

Q3: When is maximum vertical reaction likely to occur?
A: Maximum vertical reaction typically occurs at maximum torque conditions when the radial force component is at its peak value.

Q4: Are there limitations to this calculation?
A: This calculation assumes static equilibrium and may need adjustment for dynamic loading conditions and other forces acting on the crankshaft system.

Q5: How is this calculation used in crankshaft design?
A: The calculated reaction forces are used for bearing selection, stress analysis, fatigue calculations, and ensuring proper lubrication system design.
