ETP-HYCON is available on request for shafts 80 – 200 mm. Also available in stainless steel. When mounting/dismantling only one oil pump needs to be used. As the coupling is completely sealed, no oil drainage occurs, resulting in a more user- and environment friendly handling.
The hydro-mechanical couplings ETP-HYCON type S and type F consists of an outer sleeve with hydraulic connections, an inner sleeve (type F with a flange) with ETP-HFC (High Friction Coating) on the inside and an on the inner sleeve assembled cylindrical nut and seals.
When mounting both T (Taper) and J (Jack) are pressurized simultaneously. The oil pressure in T 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 into J. When the outer sleeve has been driven up a certain length, s, the pressure in T and J is released, 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 in J, to get an even dismantling process.
Benefits and features
Extremely high torque. ETP-HFC = μ 0,30
No oil leakage.
Low weight and moment of inertia.
Operated with only one pump.
Application Example : Marine
Connecting four drive shafts from two 1920kW motors on a marine application. Coupling design torque was 85kNm
Mounting: with an oil pump the outer sleeve is driven up onto the inner sleeve. When mounted there is no hydraulic pressure. The small conical angle prevents the outer sleeve from releasing.
Dismantling: the outer sleeve is in a controlled way driven back to its origin. The inner sleeve releases the contact to the shaft and the joint can be dismantled.
