Tooth Coupling

Characteristic of Tooth

Tooth coupling was developed by Gleason company from U.S.A in 1942 and was registered for Curvic by the Gleason company.
The three basic types of Tooth Coupling are (1) the Fixed Tooth Coupling, (2) the semi-Universal Coupling, and (3) the Relating Coupling.
The coupling provides a positive drive along with precision centering and high load carrying capacity.
The Fixed Tooth Coupling is used extensively in the construction of built-up turbine and compressor rotors for aircraft and industrial gas or steam turbine engines. the Fixed Tooth Coupling is also used today by many major machine tool manufactures for precision indexing mechanisms.

In the 4th Japan's machine tools exhibition in 1968, Tooth Coupling got into spotlight an important element as indexing positioning instrument.
By rapid developing of NC and CNC machine tool, Curvic has become representative of high accuracy and super rigidity.
After this, Curvic has been started to produce differently method of manufacturing the term "Tooth" in Korea.

Advantages of Tooth

• Various standardized products, the number of 360 teeth!!
  Selection range has been expanded by producing various standardized products based on the size and the number of teeth.(the number of teeth : 20-360, Outside diameter : Ø50mm - Ø700mm)
• High Rigidity!!
  High rigidity and impact resistance is achieved by increasing abrasion resistance and rigidity through the at treated Cr-mo steel.
• Precise Self-Centering!!
  By teeth mating of convex and concave teeth, precise automatic centering is realized. As master Tooth Coupling is used in the process of manufacturing, high compatibility is achieved.
• High Restoration and Division Accuracy!!
  It guarantees 1sec restoration and 5 sec remained division of the same teeth position.
• Long term quality assurance!!
  Long term quality assurance is provided by secure quality control of the entire products.
