The first thing we are going to determine is that crankshaft is a term that comes from the Latin word “ciconia”.
He crankshaft , also called crankshaft , is a axis that has elbows and that, thanks to a mechanism from connecting rod , manages to convert a uniform circular movement into an alternative rectilinear movement and vice versa.
It has its origin in an old mechanism that was used to draw water from shallow wells. Specifically, it was a system that was based on a kind of pole that had a counterweight with which the necessary force was obtained to proceed to raise the water and thus be able to enjoy it.
We can understand what a crankshaft is by analyzing the different terms that are part of the aforementioned definition. A axis It is a bar that functions as a support for a rotating body when there is a movement. The connecting rod mechanism or set, meanwhile, refers to the gear that transforms a translation movement into a circular movement, or a circular movement into a translation movement.
Given these details, we can say that the crankshaft is a cranked bar that, interacting with other components of a machine , allows the transformation of a rectilinear movement into a circular (or vice versa).
Usually the crankshafts are made with alloys very resistant, they are already subjected to an effort of great intensity. Many times they have ducts and perforations where a lubricating substance circulates.
The internal combustion engines who use the cars They have a crankshaft. With the engine in functioning , the fuel located in the combustion chamber causes an explosion that moves the piston linearly. Said movement is transmitted to a connecting rod that is attached to the piston and the crankshaft. When the movement reaches the crankshaft, it transforms it into a rotary or circular movement. The counterweights and flywheels of the crankshaft allow to minimize the irregularities that are generated in the movement of the shaft.
On more than one occasion it has happened to you that you have encountered a problem in your car due to the crankshaft mentioned. A serious problem since this element is a key part of the vehicle's engine. Specifically, among the most frequent breakdowns that you may experience are the following:
-There has been a scratch of what the wrists are, which is related to the filtering of the oil and even the lubrication. The causes of this situation can be several such that the lubricant is not doing its job properly, that it has traveled at full load with very few revolutions, that accelerations have been made while the engine is still too cold ...
-The crankshaft has been broken by fatigue. This other fault, which requires taking the car to the workshop without any doubt, can take place because the crankshaft is not well balanced, because torsional vibrations have occurred or even because a cylinder has been ignited in the wrong way.
