Benefits of DTF-Lock thread

1. Proven and reliable anti-vibration and anti-loosening functionality.
2. ProEPTTed nut and bolt service existence and fatigue existence.
3. Affective reusability.
4. No temperature variation impact and no rigorous application atmosphere prerequisite.
5. Cost-free spinning software – assembly can be accomplished with XiHu (West EPT) Dis.Hu (West EPT) Dis.n fingers until finally clamp load will increase torque is essential for closing seat. EPT to assemble and disassemble.
6. No dimensional restriction.
7. Match stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd male thread.
8. No need to have for auXiHu (West EPT) Dis.liary locking objects, these kinds of as EPT washer, locking washer, drilled/wire nut, thread adhesives, thread patches, etc.
9. In addition to DTF-Lock nuts, DTF-Lock threaded holes have the same self-locking capacity can also be produced with DTF-Lock taps. These holes can be used in different EPTT elements with self-locking prerequisite.
10. Can lessen thread stripping of comfortable content (this sort of as EPT alloy).
11. Reduced deviation of k factor (ratio of torque and clamping load)

The purpose why DTF-Lock fastener can effectively prevent thread from loosening is due to its EPT structure. There is a thirty deg wedge ramp at the root of the feminine thread. When the bolt and the nut are tightly engaged, tooth crest of the bolt thread will push tightly from the wedge ramp of the DTF-Lock thread and as a result produce large locking power. Because of to modify of the thread angle, the angle between the standard pressure created at the thread pair and the bolt aXiHu (West EPT) Dis.s is now sixty deg as an alternative of 30 deg with an regular thread. Clearly, typical power of the DTF-Lock thread is considerably better the fastening pressure. So, the anti-loosening friction pressure created by this normal force will turn into a lot better.

For the regular threads, the first two engaged threads bear 70-80% of the overall load. The other engaged threads bear only a little portion of the complete load. So, unEPTTvibrating doing work masses, fastener with regular thread sort can very easily defeat the locking power generated on the getting in touch with area and as a result produce relative turning. Then the thread will turn into unfastened.

For DTF-Lock threads, owing to its EPT framework, crest of every bolt thread push tightly towards the 30 deg wedge ramp. The load can be evenly distributed between all engaged threads. So the load can be evenly dispersed to every getting in touch with surface or level, and diverse parts of the thread can produce nearly the same anti-loosening friction pressure. It can endure transverse vibration. So, problems such as loose thread or thread stripping, and so forth. can be eliminated. In addition, fatigue toughness of the thread can also be tremendously enhanced.

The transverse load vibration check was conducted with a Junkers vibration tester in the laboratory confirmed that the DTF-Lock thread provides outstXiHu (West EPT) Dis.Hu (West EPT) Dis. anti-vibration capability (see Fig.two). They examined 3 types of nuts, i.e. regular stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd nut, powerful torque locking nut and DTF-Lock nut. Every single nut was tested for 2 minutes with the identical stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd bolt, the exact same tightening torque, the same vibration amplitude and frequency, and the identical vibration tester in the very same laboratory. The check end result was: normal stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd nut turned free extremely speedily and dropped all its locking functionality, effective torque locking nut drop 70% of its locking ability, even though DTF-Lock nut maintained its locking capability throughout the EPTT take a look at length.

Apart from, more transverse vibration tests ended up executed to examination the reusability of the 3 types of thread. The examination consequence was: the DTF-Lock self-locking nut has good reusability because it can preserve its locking power and locking performance soon after recurring screwing and unscrewing, even though regular nut and powerful torque locking nut may possibly slowly lose its locking drive and locking ability right after several occasions of screwing and unscrewing.
