Vertical Reaction on Bearing 3 of centre crankshaft at TDC position due to weight of flywheel Solution

STEP 0: Pre-Calculation Summary

Formula Used

Vertical Reaction at Bearing 3 due to Flywheel = Weight of Flywheel*Centre Crankshaft Bearing2 Gap from Flywheel/Distance Between Bearing 2&3 of Centre Crankshaft
R_v3 = W*c/c₁
This formula uses 4 Variables

Variables Used

Vertical Reaction at Bearing 3 due to Flywheel - (Measured in Newton) - Vertical Reaction at Bearing 3 due to Flywheel Weight is the vertical reaction force acting on the 3rd bearing of the crankshaft because of the weight of the flywheel.
Weight of Flywheel - (Measured in Newton) - Weight of Flywheel is defined as the force of gravity acting on the flywheel and may be calculated as the mass times the acceleration due to gravity of the flywheel.
Centre Crankshaft Bearing2 Gap from Flywheel - (Measured in Meter) - Centre Crankshaft Bearing2 gap from Flywheel is the distance between the 2nd bearing of a centre crankshaft and the line of action of flywheel weight.
Distance Between Bearing 2&3 of Centre Crankshaft - (Measured in Meter) - Distance Between Bearing 2&3 of Centre Crankshaft is the distance between the 1st and 2nd bearing of a centre crankshaft.

STEP 1: Convert Input(s) to Base Unit

Weight of Flywheel: 1427 Newton --> 1427 Newton No Conversion Required
Centre Crankshaft Bearing2 Gap from Flywheel: 200.1 Millimeter --> 0.2001 Meter (Check conversion here)
Distance Between Bearing 2&3 of Centre Crankshaft: 219.5 Millimeter --> 0.2195 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_v3 = W*c/c₁ --> 1427*0.2001/0.2195

Evaluating ... ...

R_v3 = 1300.87790432802

STEP 3: Convert Result to Output's Unit

1300.87790432802 Newton --> No Conversion Required

FINAL ANSWER

1300.87790432802 ≈ 1300.878 Newton <-- Vertical Reaction at Bearing 3 due to Flywheel

(Calculation completed in 00.004 seconds)

Types of Crank Shaft

There are two types of crankshafts—side crankshaft and center crankshaft. The side crankshaft is also called the ‘overhung’ crankshaft. It has only one crank web and requires only two bearings for support. It is used in medium-size engines and large-size horizontal engines. The center crankshaft has two webs and three bearings for support. It is used in radial aircraft engines, stationary engines, and marine engines. It is more popular in automotive engines. Crankshafts are also classified as singlethrow and multi-throw crankshafts depending upon the number of crankpins used in the assembly. Crankshafts used in multi-cylinder engines have more than one crank pin. They are called multi-throw crankshafts.

Design of Centre Crankshaft

A crankshaft is subjected to bending and torsional moments due to the following three forces:
(i) Force exerted by the connecting rod on the crank pin.
(ii) Weight of flywheel (W) acting downward in the vertical direction.
(iii) Resultant belt tensions acting in the horizontal direction (P1 + P2).
In the design of the center crankshaft, two cases of the crank, positions are considered. They are as follows:
Case I The crank is at the top dead center position and subjected to maximum bending moment and no torsional moment.
Case II The crank is at an angle with the line of dead center positions and subjected to maximum torsional moment.
