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.
Consider the Types of Tools
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.
Static or Dynamic Torque
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.
Consider the Torque Testing Process
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.
Is the torque tester being used for a torque verification process?
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.
Is the torque tester being used for a torque auditing program?
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:
- First movement in the fastening direction
- First movement in the loosening direction
- Determination of the rotation angle
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.
Connection to External Torque Testers
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.
Testing Pulse Tools
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.
Why is it important to test torque?
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:
- To determine good assembly from bad – essential for keeping everything safe
- Preventing the loss of energy through connections that are not tight enough, resulting in the dissipation of energy at loose connections
- Ensuring that connections are not overly tightened and stripped, which could also lead to failure. Simply tightening a “hot” connection detected using infrared inspection is usually not sufficient to correct the problem.
- Torque measurements can provide information on the root cause of a problem identified during the test
- Manufacturers can identify and address these problems at the source
Measuring torque is an essential component of manufacturing. With such an important task at hand, the right tools should be used to ensure that torque is measured with absolute accuracy. This is where Delta Regis can help you with your tasks.
When it comes to torque testers, the right type of tester is dependent on the specific project needs. It’s important to ask yourself what the torque tester is being used for and the tools on which it will be applied.
The torque testing needs of manufacturers differ greatly, which is why a broad range of torque testers are available to satisfy all project demands. When selecting a torque tester, it is key to select a flexible device, offering you the ability to cover a wide range of torque.
