Product Information

CURVIC COUPLING
CURVIC COUPLING Is Product Description

Curvic Coupling Use for Turret of CNC Lathe
Machining Center, Robot, Gas Turbine, Airplane, etc

| Feature

Accurate and precise centering

The curvature of the teeth give these couplings their very own and unique self-centering feature. One member is ground with the outside edge of the cup type grinding wheel to form a concave-shaped tooth. The mating member is ground with the inside edge thus producing a convex-shaped tooth. Both halves of the couping are ground to ensure that they mesh at the center ot the teeth. The coupling has the advantages of accurate alignment and precision centering when-ever they are in mesh.

High indexing accuracy of ±2 sec of arc.

This very high accuracy is achived by the prease self centering centering feature of the wide spread tooth contecting uniformly over all the teeth.

High wear resistance

High grade case hardened steels are used to manufacture the couplings. The teeth are first cut, hardened to HRC 60 and then accuretely ground. This gives a high level of durability to the precision tooth profile which means that the coupling retains its high accuracy characteristic over a long period of use.

Curvic Coupling

Because it can receive enough hardness and big clamp force at Machining Center of Index Table. High Torque Is suitable by power transmission purpose Curvic Coupling's Allowable load differs according to size. Allowable Cutting Load, Allowable Torque, and Force Clamp is calculated and decided according to it's usage
