The torque required to initiate turning is referred to as breakaway. The DI-12 outputs torque data continuously (in PD mode) to data acquisition software via the USB virtual COM port, enabling the display of breakaway torque profiles. This process involves applying additional torque to a tightened fastener to detect actual tightened torque as the fastener starts moving. Automatic Breakaway Torque Tester . The new torque tester had to be able to test tamper-evident closures for breakaway (or slip) torque and bridge torque on a wide range of plastic and glass bottles and pots. After being tightened, and torque is applied, there is a point when the fastener begins to move again. Breakaway torque is defined as how much torque is required to start a part’s rotation from a stationary … Controlling the tightening torque on fasteners (bolts and screws) being tightened by impact and non-impact power tools is challenging. As a result, “applied torque” does not equate to “actual tightening torque.“ For this reason, auditing the actual tightening torque is critical. Torque is applied to tip caps on disposable medical syringes to determine their breakaway torque. Power tools provide dynamic torque that can vary depending on many variables, such as joint material types, joint layer thicknesses, temperature, the presence of lubricants, etc. Once breakaway torque is measured, power drivers can be reset to the proper tightening torque.

Spillage on filling can either … We tend to look at movement at about 3 degrees of rotation. To prevent transverse frictional forces, the holding fixture and support bearing are mounted on a common precision slide … PD determines breakaway and yield torque (CW only). This will be proportional to the mass being rotated and its moment of inertia. The peak torque or peak down torque in breakaway tests is captured automatically. but if requirement falls outside of limits a tool can be made to suit. PP Displays peak torque values. Loosening test also called breakaway test operates similar as the movement check except an extra force is employed to the fastened bolt in the loosening direction. That means the tool … Part of testing the fastener includes measuring the … The bearing preload is determined by measuring the torque required to rotate the inner race while the outer race is held. However, auditing fasteners made of plastic or small-size screws is often challenging, as standard breakaway testing will not always show a clear dip in torque. Series TT01 Cap Torque Testers are designed to measure the application and removal torque of bottle caps. Adjustable posts effectively grip a broad range of container shapes and sizes, while optional flat and adjustable jaws are available for unique profiles. kebamerica.com . PD determines breakway and yield torque (CW only). Once torque has been applied to a joint, an audit function measures exactly how tight that fastener was torqued. This test method is to be used to measure the locking torque, breakaway torque, torque off and preload of threaded collars. These wrenches feature a large easy to read dial with an indicator needle to record the highest torque before the breakaway occurs. This is the torque due to the locking element only. If the breakaway force of a nut is too low, the vibration of the equipment may cause the nut to loosen; if it's too high, the threads may strip and the bolt may be impossible to remove. The torque testers had to have clear intuitive controls, with easy-to-read pass/fail parameters, an on-board memory to keep statistical results, and also had to be waterproof for testing on the production floor. q�R�. ̀�+�s�b�Q�X Step 1 – Insert Breakaway Torque Tool into Bearing Insert breakaway torque tool into bore of the bearing until the flange sits flush against the bearing.

The syringe barrel is gripped firmly in a holding fixture. If the load torque is higher than the breakaway torque of the motor, then the motor speed decreases below the breakdown–torque speed (in extreme cases down to 0); the drive breaks down. The DI-12 also can be used to detect the yield torque value of a specific joint, to help establish an ideal tightening torque value by testing—not by commonly used calculation methods. With our clamps, breakaway torque is determined in the development phase in order to ensure that sufficient clamping force – in addition to all existing requirements – is maintained. In order to test the light breakaway and running torque values required to operate the dosage dial, it is essential to eliminate friction and position the sample with absolute concentricity. Virtual RS-232 (9600 bps): PP 1 peak data, PD 80 data/sec. Breakaway torque is the turning force required to initiate rotation (similar to static friction), and running torque is the turning force required to keep a system in rotation (similar to kinetic friction). A rugged aluminum design and simple, intuitive operation allow for use in laboratory and production environments. Aero Staking Break Away Torque testers and receiver cups are made-to-order devices that are designed to help measure effectiveness against the requirements of the customer specification. Emperor TM Torque software: Unlimited capability for all closure torque tests. With this strategy, a digital torque wrench applies torque to rotate the screw further, and measures the torque at the point where the screw starts moving.

Breakaway torque tests require a skilled, experienced operator to sense when the bolt begins to breakaway. This breakaway point is detected as an initial peak, and is followed by a reducing running torque. The tester features three measurement modes: TR, PP and PD. The Imada Cedar DI-12-SL Automatic Breakaway Torque Tester is designed to find the actual yield tightening torque value for specific thread joints which consist of a variety of thread types, multi-layered material, hole sizes, etc.Torque controlled power tools are set to apply consistent torque, but fasteners are not necessarily tightened to that value if the tools are not calibrated. The Series i torque calibrator displays Max, Min and Avg statistics. Using an Imada DI-12 motorized auto-detect breakaway torque tester, operators achieve a more reliable and consistent breakaway torque measurement, even in the case of small or plastic fasteners. The IMADA DI-12 automates this complex operation. The amount of torque necessary to loosen the bolt is the torque applied to the bolt in the beginning. breakaway (slip) torque . This test is also known as the “breakaway” test. Loosening Torque Test. That point of movement is "breakaway torque." ISO-17025 Certificates are available at an additional charge.

The end of the tip cap is carried in a support bearing. We do this in relaxation tests, for example. The greater the friction, the greater breakaway torque required. There are two basic types of torque-to-turn tests: Breakaway torque (BT) is required to get the shaft moving, to overcome the inertia of the crankshaft and the static friction between it and the seal. The Importance of Torque Auditing What is breakaway torque or as others call it, Residual Torque? Friction keeps a closure secure, and reduces as a screw thread is turned. Bearing Preload Test with TorquePRO In the manufacturing of Precision Bearings, every bearing must go through a final quality test where the breakaway torque and the running torque are measured to determine the bearing preload. Additionally, performing a good breakaway test requires a skilled operator and many hours of training and experience. It’s easy to use and provides rapid, reliable testing for actual tightening torque. This assumes (theoretically) that torque values dip down briefly before climbing to higher than original tightened torque. The friction may be between the container finish or seal and the cap or its liner, in the screw thread or threads, or all of these. ���`>S�^�D嬽%�X��&��_��F:I��D?�ӕ�s$ ,M��Gŭpٮa���:���V�׹�X��.�1����D8j����O���}�k��.
