Overhung Crankshaft
With an overhung crankshaft, you have the crankshaft supported at only one end and do not need a connecting rod with a split big end. This makes it a bit cheaper to manufacture and easy to assemble. But the connecting rod is now cantilevered so the load seen by the support bearing of the crankshaft, in this case, is piston force + moment load (due to offset) and needs to be considered when choosing the bearing for this kind of system. Designs with this overhung crankshaft generally use a double roll ball bearing or two deep groove ball bearing with a small distance between them to handle this moment load. This design is common in smaller air compressors with low working pressure. With a regular crankshaft, you have support on both sides which makes for robust construction. That is why you see them on engines, big compressors, etc.
How to Calculate Horizontal Reaction on Bearing 1 of side crankshaft at TDC position due to belt tension?
Horizontal Reaction on Bearing 1 of side crankshaft at TDC position due to belt tension calculator uses Horizontal Reaction at Bearing 1 due to Belt = ((Belt Tension in Tight Side+Belt Tension in Loose Side)*Side Crankshaft Bearing2 gap from Flywheel)/Distance Between Bearing1&2 of Side Crankshaft to calculate the Horizontal Reaction at Bearing 1 due to Belt, Horizontal Reaction on Bearing 1 of side crankshaft at TDC position due to belt tension is the horizontal reaction force acting on the 1st bearing of the side crankshaft at Top Dead Centre position because of the belt tensions, And when the side crankshaft is designed for the crank at the top dead center position and subjected to maximum bending moment and no torsional moment. Horizontal Reaction at Bearing 1 due to Belt is denoted by Rh1 symbol.
How to calculate Horizontal Reaction on Bearing 1 of side crankshaft at TDC position due to belt tension using this online calculator? To use this online calculator for Horizontal Reaction on Bearing 1 of side crankshaft at TDC position due to belt tension, enter Belt Tension in Tight Side (P1), Belt Tension in Loose Side (P2), Side Crankshaft Bearing2 gap from Flywheel (c2) & Distance Between Bearing1&2 of Side Crankshaft (c) and hit the calculate button. Here is how the Horizontal Reaction on Bearing 1 of side crankshaft at TDC position due to belt tension calculation can be explained with given input values -> 336.6667 = ((750+260)*0.2)/0.6.
