Whether it is a fastener such as a nut, screw, or electrical equipment such as an electric motor, it needs a force to turn. However, if you fasten the nut too tight, this excessive Torque can lead to stretching and, consequently, breaking bolts. On the other hand, if you provide it with insufficient Torque, it will result in loose connections. To ensure quality in manufacturing or repairing, you need to perform torque testing.

What is Torque Testing?
Torque testing is the measurement of the force you apply on particular machinery. This method tries to determine how the object under observation will react to turning it commonly and excessively.
Consider a typical scenario of tightening nuts of the tire while changing it for puncture. Here you have to apply a torque test to avoid loose bolts on the go. For testing the Torque, you will insert a torque transducer between the turning tool, i.e. the wrench, and the object on which you are applying force, i.e. the nut. If this force is sufficient, you are ready to continue your journey. Otherwise, you will fasten the bolts again.
When to test the Torque?
Testing the Torque is vital while dealing with machinery with rotating parts such as engines and motors. Some typical applications for torque testing are
To Check Fastening
In the assembly process of heavy and complex machinery, you will involve several screws and nuts. At this point, the manufacturer must ensure proper fastening. However, suppose there are loose fasteners. In that case, the integrity of the entire machinery will be at stake, which can cause severe danger to innocent lives.
Therefore, you have to tighten the bolts until it achieves its maximum Torque. Nevertheless, there may be many cases where the threaded fastener has malfunctioned. If so, your nut will reach the peak torque value, and in actuality, it has not completed its turns at all. Hence, to cater to such a situation, you need objective measures.
One proven method is to capture the Torque vs angle signature during the fastening process. By this, you will identify the number of full rotation angles that the object has moved when it gets to the maximum torque value. In addition, you can check whether the fastener is the root cause of the defect or any other issue is also present.
To Check Torque-to-Turn
Torque-to-turn is the force a system need when overcoming the inertia and friction it faces from its environment. Shaft and bearing assemblies undergo tests for these two types of torques
Consider a simple motor that has to overcome the friction around it to get moving. For that, it may use fuel or electricity to produce enough energy for breaking away from inertia. This friction may be the result of insufficient lubricant, damaged parts, or debris inside bearings. Greater is the force of friction; more significant is the energy that it will use up.
Just like the fastening process, you can check for a predetermined value of Torque and use it to check whether the engine is assembled correctly. Yet you need to dive into the details for proper analysis of the machine. Record the Torque vs time signatures and you will get to know the performance at each second, thus unveiling the issue.
Likewise, in testing the running Torque, you can check for the predefined highest value, but this will result in no more profound analysis. In this case, you again can record Torque vs angle signatures. Observing it will lead you to identify whether your problem has to do with damaged gears or their geometric imperfections.
How to perform Torque Testing?
With experience, you may know the proper torque of equipment it needs for fixation. Even so, you need to conduct a periodic audit as time passes to maintain the system. General testing methods that you can opt for are
For this method, use a wrench with a torque meter on it. Rotate the already fixed fastener in the direction you moved it while tightening. Upon a slight movement of the bolt, note the value on the meter. You will get the original Torque the joint needs for fastening. Note that do not move the nut further as it will cause damage.
Here, you will note the torque reading as the fastening breaks lose. It will give you the value of the approximate Torque you need for the joint.
Things to Consider Before Getting a Torque Tester
You need to measure the Torque at all stages of manufacturing and assembling. For that, you will need an appropriate torque measuring tool for proper torque values. Torque tester can be an investment of your business, which will not waste since it will benefit you in a project. By using a suitable torque tester, you can save yourself and your assembled machinery from various defects.
To choose from a range of torque testers, you need to understand your work type. So a little pre-purchase research will help you in making the right choice. In our opinion, there are 7 things you should consider before choosing a tester.
Understand the type of tools
For each of the different types of equipment, there are types of testers available in the market. When you purchase one, you need to see whether it has the complete functions that you need or not. Therefore, knowing the type of tools that you will be handling will narrow down the choices, and you will get your required tester.
Consider the type of measured Torque
There are two types of Torque, static or dynamic. With each class, different factors will play a role in the accuracy of data found. Hence, before selecting a tester, you must identify whether you are working with static Torque or dynamic Torque to minimize errors.
Understand the type of Torque Test
Different tests require special testers with meters installed on them for the specific value like the above cases. Two approaches to test the Torque are
Each technique requires a unique type of sensors and thus special testers. That is why it is an essential factor to consider.

Check if you want the tool for Torque Verification
As shown above, torque testing involves three methods: the fastening, loosening, and marking test. So if you want to test the joint relaxation points from the following tests, you need to consider them before buying the tester.
Check if you want the tool for Torque Auditing Program
In auditing, you validate, inform and then confirm a specific thing. It is necessary to check the performance of a job, and it is a preventive measure on latent failures. To audit the Torque, you need to test
Hence, your tester should be able to check for all these values if you want them for the auditing program of Torque.
Check the need of using external sensors
In many situations, you need an external sensor, as you have to enter the value into some software. If so, you have to a digital torque tester that is compatible. That way, it will convert the value into an electrical signal. The system will utilize it in the decision-making process.
Check the need for Pulse Tools
Similarly, your project may need some pulse tools to provide torque to your system in small increments. For that, you need a torque tester that measures the Torque and the pulse too. This type of tester could be very beneficial for the other projects because it gives you more information and accuracy. You can further use this data to schedule your maintenance schedule for the device.
Conclusion
Since insufficient amounts can cause joints to lose and disconnect the machine, you need to test it over the period. Over tightening of the nuts also give them no benefit as extra force can cause wear and tear of the fasteners. So, torque Testing is necessary.
By the way, to keep your motors safe, you need to assemble them with care and perfection. Here at Cloom, we offer custom wiring assembly with attention to each detail so that your devices are easy to maintain. Please fill the form and contact our team now.
Torque is the measurement of the force that can cause an object to rotate about its axis. Understanding and measuring this force is important in several industries, including manufacturing.
Although it may seem minor, the measurement of torque should not be neglected. It can lead to the selection of incorrect torque measuring equipment, which is then used for torque testing applications.
There are several different torque testers to choose from, so it&#;s important to do your research before setting out to buy a torque tester of your own. Researching in advance can help you sort through the various types of torque analyzers, each offering slightly different features, and select the best torque tester to serve your specific project needs.
If selected correctly, a torque tester can be very beneficial for your project. It&#;s a good idea to use all the available resources, including asking for assistance from a torque expert or requesting a product demonstration.
A torque tester is an essential instrument of the tool kit to test, calibrate, and monitor torque applications. Torque should be measured at all stages of the assembly process, including before, during, and after assembly.
Understanding your project needs is the first step of the torque tester selection process. Taking the time to conduct some research and asking yourself some key questions will help you make the right choice the first time. If you&#;re getting ready to purchase your torque tester, we&#;re here to help share a few things you should know before doing so.
A torque tester is used to test and calibrate torque applications, so knowing the types of tools you intend to test and calibrate is the first question you should be asking yourself.
It&#;s also important to ensure that the torque tester you select will cover the full range of torque measurements for all the different types of tools used. The types of tools you are testing and calibrating will help guide your decision to select the correct torque tester.
Understanding the type of torque intended to be measured and the different types of torque testers available plays a major role in the accuracy of the data gathered by the measurement tool. Before selecting a torque tester, it&#;s important to determine whether the torque being measured is static or dynamic, or both.
Static torque does not produce an angular acceleration. For example, someone pushing on a door is an example of static torque because it does not rotate about its hinges. Alternatively, dynamic torque refers to an accelerating force, such as the drive shaft in a racing car, which accelerates from the starting line.
Testing torque is relatively simple and is achieved by inserting a torque transducer between the tool that is applying the force and the item against which the force is being applied. In order to select the correct torque testing equipment, it&#;s important to define the torque testing process being used.
There are two different approaches to measuring torque, including reaction and in-line. The in-line method of torque testing measures the torque required to turn the rotating part, while the reaction method measures the amount of force required to prevent the part from rotating. Each of the two testing methods uses different specialized sensors. This is why it&#;s important to consider the torque testing method, prior to purchasing your torque tester.
As a form of quality control, torque should always be carefully measured and monitored. Insufficient or excessive torque can cause a screw or bolt to loosen or overstretch and break, respectively, which is why torque should always be verified periodically.
Testing torque involves a sequence of three methods, including the movement check, the loosening check, and the marking check. It&#;s important to ask yourself whether you will be conducting torque verification procedures, before selecting your torque tester.
Auditing is a process used to validate, inform, and confirm. Torque calibrations must be completed to ensure accuracy and repeatability. Auditing is important to gain information about how a job was performed, even if it is controlled perfectly, and is a preventative measure to help eliminate the possibility of failure.
Torque auditing is a way to validate the fastening process, the torque tool itself, its design, and the materials used in the application. There are three main types of audit methods:
Before purchasing your torque tester, ask yourself whether it is being used for an auditing program and the type of auditing method used to help guide your decision.
Many torque testers allow the flexibility to connect with external torque sensors. A torque sensor or transducer converts torque into an electrical signal. If you require a torque sensor to be connected to your torque tester now or in the future, it&#;s important to consider this when selecting your torque tester.
Many manufacturers utilize pulse tools, which are discontinuous-drive tools. Pulse tools apply torque in small increments rather than in one continuous stream. If pulse tools are being utilized, it&#;s important to consider purchasing a torque tester that measures both torque and pulse counts.
A torque tester that can also measure pulse counts is unique and provides very useful data. This data is used to guide the setting of torque on pulse tools and evaluating its maintenance schedule.
Verifying that the required torque setting is achieved is an important part of any manufacturing project. Measuring torque is an essential practice for companies who wish to ensure the quality, safety, and reliability of their tools. There are a number of benefits of torque testing, including:
