Extremely easy and economical to use, these couplings are particularly suitable for electric motors. Axial, angular or lateral offset should nonetheless remain limited. If this is not the case, or if the power or vibration is very high, use of tyreflex couplings is then recommended.
LIGHTWEIGHT: due to their low moment of inertia, these couplings are particularly recommended for intermittent operation electric motors (frequent startups).
SAFE: even if the spider element deteriorates, these couplings will still "hold" and transmission is not interrupted.
Couplings are made up of 3 parts (two flanges and a spider element) avec 3 possiblités de combinaisons :
- Coupling YZ : 1 flange Y + 1 flange Z + 1 spider element.
- Coupling YY : 2 flanges Y + 1 spider element.
- Coupling ZZ : 2 flanges Z + 1 spider element.
(*) Y taper bush is made of steel, not cast iron.
