Breakaway torque tests require a skilled, experienced operator to sense when the bolt begins to breakaway. This is the torque due to the locking element only. 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. The most common torque auditing method is breakaway testing. 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. Once breakaway torque is measured, power drivers can be reset to the proper tightening torque.

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. Plain Bearing No-Load Rotational Breakaway Torque Measurement ARP5448/5 This test method provides a procedure for measuring no-load rotational breakaway torque of self-lubricating spherical bearings. Run sophisticated routines for closure system product development and design optimisation. This breakaway point is detected as an initial peak, and is followed by a reducing running torque. PNote Calculation results of the test self-locking torque statistical control methods pnooesu (SPC) has no statistical significance a Clamping force nuts for strength class 04 is equal to 80% of the test load for nuts strength class 04 nominal diameter of 3 mm . 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. q�R�. 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. If breakaway torque value is detected, the green indicator will light, and tester rotation will stop automatically. The amount of torque necessary to loosen the bolt is the torque applied to the bolt in the beginning. This will be proportional to the mass being rotated and its moment of inertia. These wrenches feature a large easy to read dial with an indicator needle to record the highest torque before the breakaway occurs. At the exact position that the bolt breaks loose, note the reading and mark it off. PP Displays peak torque values. Instead of applying torque in the tightening direction of the fastener, this test uses force in the direction that loosens the fastener. Part of testing the fastener includes measuring the … 3100 Dundee Rd., Suite 707, Northbrook, IL 60062 © Copyright 2021ISO 9001 Registered & ISO/IEC 17025 Accredited  Phone: 847-562-0834  Fax: 847-562-0839, ISO 9001 Registered & ISO/IEC 17025 Accredited. !��,/�Lܼ�:��O�����/8܀NXD-k�*�5�p�|�dӱ����.��u.�\���+���_��2�Wˣ�M���AG wI!}�d�ِ&���]A����⍣Jafn�������2�#L�cn*w䵈�f��! h�bbd``b`� $_��" �tD��� �K@�;HX�q v��[ �u �w����@,!�fs������b``�M�g��` 3�@ endstream endobj startxref 0 %%EOF 257 0 obj <>stream This assumes (theoretically) that torque values dip down briefly before climbing to higher than original tightened torque. "Rc���� endstream endobj 234 0 obj <>stream 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. PP Displays peak torque values. The tester features three measurement modes: TR, PP and PD. 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. If breakaway torque value is detected, the green indicator will light, and tester rotation will stop automatically. Step 2 – Select Gauge Pin The greater the friction, the greater breakaway torque required. The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. 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. The tip cap is held in a positive-fitting fixture with toothed pulley and belt. 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). To prevent transverse frictional forces, the holding fixture and support bearing are mounted on a common precision slide … %PDF-1.5 %���� Torque-to-turn These measurements are an essential validation and diagnostic tool for any assemblies where the primary function involves rotating parts, such as engines, motors, transmissions or axles. Ranges DI-12-SL Ranges (Resolution) Accuracy: ±1% F.S., 1LSD. The peak torque or peak down torque in breakaway tests is captured automatically. Typical, standard tools work within a range 5-170in/lbs. 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. �bu5j��[����e�%���&.

Mechanics and engineers often measure the breakaway torque of threaded fasteners in part to ensure product integrity as part of a process called torque auditing. 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. There are two basic categories of torque-to-turn tests: breakaway torque and running 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. Test fixture for tip cap breakaway torque with a single-axis testing machine Torque is applied to tip caps on disposable medical syringes to determine their breakaway torque. Emperor TM Torque software: Unlimited capability for all closure torque tests. That point of movement is "breakaway torque." What is breakaway torque or as others call it, Residual Torque? The tip cap is held in a positive-fitting fixture with toothed pulley and belt. It is similar to the “ first movement ” method, with one basic difference. On this basis, we recommend the tightening torque and tightening speed that must be complied with to our customers. This will change with reuse and be referred to as the “1st Off”, “5th Off” torque and so forth. The bearing preload is determined by measuring the torque required to rotate the inner race while the outer race is held. PP: Displays PEAK Torque value that will not change until a higher value is measured. TR displays real time torque values. Friction keeps a closure secure, and reduces as a screw thread is turned. A rugged aluminum design and simple, intuitive operation allow for use in laboratory and production environments. 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. 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. ISO-17025 Certificates are available at an additional charge. After being tightened, and torque is applied, there is a point when the fastener begins to move again. What is Breakaway Torque Used for? DI-12 Breakaway Torque Tester. TR displays real time torque values. The torque required to initiate turning is referred to as breakaway. Additionally, performing a good breakaway test requires a skilled operator and many hours of training and experience. 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 International Standard describes torque and preload test method for threaded collars. Torque is applied to tip caps on disposable medical syringes to determine their breakaway torque. The IMADA DI-12 automates this complex operation. The DI-12 can also detect yield torque value for a specific joint, to easily establish ideal tightening torque. The syringe barrel is gripped firmly in a holding fixture. The larger impact wrench method would be done by using the more powerful tool to tighten a nut/bolt over the maximum torque which the impact being tested could achieve on it’s own (for example — 1,100 ft-lbs). *�����oZN?���(w�h�p��/ Breakaway Torque — The torque necessary to start relative ro-tation between a locking fastener and its mating thread with no axial load on the screw. Loosening Torque Test. 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. We stock dial indicating torque wrenches and torque test adaptors for bearings from .187 inches I.D. Adjustable posts effectively grip a broad range of container shapes and sizes, while optional flat and adjustable jaws are available for unique profiles. 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.
