EMUGE Self-Lock integrated thread locking system

Product catalog summary
Introduction
The document introduces EMUGE SELF-LOCK threading tools, which are designed to create self-locking internal threads. These tools integrate a thread locking system, eliminating the need for additional, often costly, locking devices.

Standard vs. SELF-LOCK Threads
Standard screw connections concentrate stress on the first thread, risking stripping, especially in soft materials. The EMUGE SELF-LOCK system distributes stress evenly across the thread length, preventing stripping and allowing for repeated use.

Features of EMUGE SELF-LOCK Internal Threads
  • Integrated thread locking within the internal thread.
  • Modified profile with a 30-degree ramp surface for self-locking.
  • Easy assembly with no risk of forgetting the locking device.
  • Compatible with standard external threads.
  • Even stress distribution prevents thread stripping.
  • Cost-effective as no additional components are needed.
  • Maintains holding power under dynamic stress.
  • Threads can be produced using EMUGE taps, cold-forming taps, or thread milling cutters.


Performance Comparison
The EMUGE SELF-LOCK thread maintains its holding power under dynamic stress better than standard threads, even after repeated loosening and tightening. The design ensures a more even load distribution, reducing the risk of stripping.

Designation and Gauging
  • The SELF-LOCK profile is marked with "LK" before the thread size.
  • Designations "BT" (Back Taper) and "TT" (Top Taper) indicate the direction of the ramp surfaces.
  • Gauging is recommended using EMUGE's two-piece gauge system to ensure accuracy.


Applications and Specifications
The document provides detailed specifications for various materials and thread types, including cutting speeds and feed rates for different steel and stainless steel materials.

Conclusion
EMUGE SELF-LOCK threading tools offer a reliable and efficient solution for creating self-locking threads, reducing the need for additional locking devices and ensuring durability and performance under dynamic conditions.

...die integrierte Gewindesicherung ... the integrated thread locking system Thread Cutting Technology Schraubenverbindungen sind lösbare Verbindungen. Um ungewolltes Lösen besonders unter dynamischen Beanspruchungen zu vermeiden, bedarf es häufig zusätzlicher Sicherungselemente. Diese verursachen Kosten, sind nur bedingt wiederholt verwendbar und zum Teil temperaturempfindlich. Screw connections are generally made so that they can be loosened again. If an involuntary loosening of threads, especially under dynamic stress, must be avoided it is often necessary to use additional locking devices....

Dies ist eine Folge von Steigungsdifferenzen zwischen Außen- und Innengewinde.
