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 crucial for determining bearing loads and ensuring proper crankshaft design.
The calculator uses the formula:
Where:
Explanation: The formula calculates the vertical reaction force at the second bearing based on the principle of moments and force distribution in the crankshaft system.
Details: Accurate calculation of vertical reaction forces is essential for proper bearing selection, crankshaft design optimization, and ensuring the mechanical integrity of the engine system under maximum torque conditions.
Tips: Enter radial force at crank pin in Newtons, overhang distance in meters, and distance between bearings in meters. All values must be positive and non-zero for accurate calculation.
Q1: What is radial force at crank pin?
A: Radial Force at Crank Pin is the component of thrust force on connecting rod acting at the crankpin in the direction radially to the connecting rod.
Q2: How is overhang distance measured?
A: Overhang Distance of Piston Force From Bearing1 is the distance between the 1st bearing and the line of action of piston force onto the crank pin.
Q3: Why is this calculation important at maximum torque?
A: Maximum torque conditions produce the highest forces on the crankshaft, making this calculation critical for ensuring structural integrity and proper bearing performance.
Q4: What factors affect the vertical reaction force?
A: The vertical reaction force depends on the radial force magnitude, the geometry of the crankshaft (overhang distance and bearing spacing), and the load distribution.
Q5: How is this result used in crankshaft design?
A: The calculated vertical reaction force is used to determine bearing loads, select appropriate bearing sizes, and verify the structural adequacy of the crankshaft design.
