An engine/compressor crankshaft has several places where rods to the pistons are connected. The rods are on a pin which is offset from the center of the crankshaft.
Thus, as the crankshaft rotates, the pin orbits in a circle around it.
The connecting rod is thus forced back and forth, due to the pin's motion.
The pin is connected to the crankshaft by two pieces called WEBs.
On a perfectly-aligned crankshaft, the distance between the two webs is constant, even as the shaft rotates.
However, after months of constant use, the mounting of the engine/compressor can change: ground settling, worn support structures, bolt tension changes, etc.
When this happens, the distance between the webs can start to vary with rotation. The amount of variation in this distance is called WEB DEFLECTION.
That means the webs are subject to cyclic stress every rotation, and if severe enough, the crankshaft can be destroyed.
WEB DEFLECTION is thus an indicator of the state of crankshaft alignment. Even a few mils variation is indicative of trouble. Manufacturers recommend checking this periodically, and re-aligning the shaft if the deflection is over a given limit.
Here is a drawing of a crankshaft, with the web labeled:

You have rod bearing caps that hold the rods on the crankshaft. And you also have main bearing caps that hold the crankshaft in the engine block. NEUTZ.
The Crankshaft Position Sensor senses it's position from a toothed timing ring behind the Crankshaft pulley. The CKP is above and to the left of the crankshaft pulley.
An automotive engine's camshaft rotates at A. the same speed as the crankshaft. B. one-quarter the speed of the crankshaft. C. one-half the speed of the crankshaft. D. twice the speed of the crankshaft.
Main bearings are between crankshaft and main journals (engine block), rod bearings are between connecting rods and crankshaft and thrust bearings ensure crankshaft does not slide horizantally between journals they hold crank in place.
flaxibility on cranck shaft during the operation ,if we will not find deflection on cranck shaft it mean it's can be broken or band.
due to running in excess of maximum continous rating...
Crankshaft used to transforms the linear motion of the pistons into a rotational motion that is transmitted to the load.Piston connected with crankshaft by connecting rod.Each units of the crankshaft supported by crank bearing(usually journal bearing) In multi-cylinder engine every units piston connected with crankshaft create rotational motion according to firing order.Crank shaft alignment is necessary for smooth engine operation.
It is the deflection on the screen (meter) per volt of deflection
maximum deflection will accure
Deflection is a change of course, essentially. An example sentence would be: His deflection, eventually, brought him to meet his wife.
The Coriolis effect is the clockwise deflection of air in the north hemisphere and the counterclockwise deflection in the Southern Hemisphere.
The Coriolis effect is the clockwise deflection of air in the north hemisphere and the counterclockwise deflection in the Southern Hemisphere.
Electromagnetic deflection is used because it can create greater deflection angles of the electron beam compared to electrostatic deflection.
Yes. On a unintentional deflection...
The deflection of the ball caused it to change direction. The politician used deflection to redirect attention away from the controversial issue. The deflection of the light off the mirror created a dazzling effect in the room.
