Rigid flange coupling
14.7 - 1 960 kNm | ETP-HYCON F/FX
ETP
ETP-HYCON F and FX are compact rigid shaft-flange couplings for high performance, quick mounting/dismantling and thus short downtime. Type FX is longer than F and can transmit considerably higher torque. Both types are type approved by DnV for marine applications.
CONSTRUCTION
ETP-HYCON F and FX both consists of an outer sleeve with hydraulic connections, an inner sleeve with a flange and ETP-HFC on the inside and an on the inner sleeve assembled cylindrical ring and seals.
OPERATION
When mounting both two connections are pressurized simultaneously. The oil pressure lubricates the contact surfaces in the axial space between the seals. This facilitates the movement of the outer sleeve, which is forced to move because of the axial force created by the oil pressure. When the outer sleeve has been driven up a certain length, the pressure is released and the outer sleeve compresses the inner sleeve to an even surface pressure to the shafts. A rigid strong joint has been created.
Dismantling is done in same way, but with a lower pressure to get an even dismantling process.
QUALITIES
The unique ETP-HFC treatment which increases the friction considerably, the hydro mechanical principle and the through seals closed oil chambers together gives a great number of advantages:
* High transmittable torque.
* High torsional stiffness.
* Quick mounting/dismantling.
* Low weight, low polar moment of inertia.
* No oil drainage.
* Compact design.
* The flange does not move axially during pressurizing.
