The key moment or sometimes called the torque wrench is one of the important equipment in the automotive industry. Without the moment lock, the engine components in the vehicle cannot be assembled properly. To understand how the work, types, and key functions of a moment, you can listen to the following explanation.
Definition of Torque Wrench
To combine material or machine components, there are many ways you can do it. One way is to use nuts and bolts. This method is the easiest and most efficient way. Even so, to be able to get after the right nuts and bolts requires its own abilities and experience.
Nuts and bolts that are not tightly mounted will obviously be dangerous, but if they are installed too tightly it can also have an impact. For that, you need to know the size of the torsional force or the tightness of the nuts and bolts to be glued. Key moments can help you find out. This tool will show the value of firmness in accordance with the pair of nuts and bolts that you use.
The appearance and workings of the actual moment key are similar to other keys. The difference only lies in the measuring indicator which is located near the handle or lock handle. Whereas at the other end is a socket wrench that can be used to tighten nuts and bolts.
Torque Wrench Function
Then, what exactly is the key moment function? Besides functioning to tighten nuts and bolts, the moment lock also has other important functions. The function is to measure the most appropriate tightness value of nuts and bolts.
This is because basically nuts and bolts do have their respective tightness values. Not always good tightly installed nuts and bolts. In some conditions, nuts and bolts that are tightly attached can actually cause damage. For this reason the key moment is needed so that the nut and can be attached with the appropriate moment.
Types of Torque Wrench
Since it was first discovered in 1931 by John H. Sharp, the key moment continues to experience innovation to match needs. The innovation certainly makes the key moment has a variety of types and shapes. Here are some types of key moments that are often used.
Torque Wrench Deflecting Beam
This type of torque wrench indicates the value of firmness by using the number indicator indicated by the needle. The shape resembles a sword with the end in the form of a socket wrench and a needle on the other end. The needle will move according to the magnitude of the moment of tightening of the nut and bolt.
Torque Wrench Dial Type Indicator
The next type of key moment is the indicator dial. As the name implies, this type of moment lock uses a dial indicator (dial gauge) to show the value of firmness. The level of accuracy of the key moment indicator dial is fairly high, in the range of 0.01 to 0.001 mm. This tool is commonly used in the automotive industry.
Torque Wrench Click Adjustable
Besides the needle moment lock and indicator dial, there is also a click type moment lock. In this type of moment lock you can adjust the firmness value without having to look at the scale or indicator hand (as in the needle type moment lock). To find out the value of firmness, you just hear the sound of 'click'.
The torque wrench is an important tool when you need to know the right moment and value of firmness. From this article, you can find out what is the moment key, moment key function, and types of moment key. May be useful.
