Hardened steel shaft-hub rigid coupling
40 - 18 000 Nm | ETP-TECHNO
ETP
CONSTRUCTION
ETP-TECHNO consists of a double-walled hardened steel sleeve filled with a pressure medium, and a flange. The flange part contains the pressurizing mechanism, which consists of a screw and piston with double sealing function, an o-ring and a metallic seal with a steel ball, which is pressed against spherical a seating.
The outer and inner diameter and the side of the flange towards the hub are accurately machined for extremely good concentricity.
The pressurizing mechanism is designed for 1000\'s of mountings.
OPERATION
When the pressure screw is tightened the double-walled sleeve expands uniformly against the shaft and the hub thus creating a rigid joint. Dismantling of the joint is done by loosening the screw. ETP-TECHNO returns to its original measurements and can easily be dismantled.
QUALITIES
The unique hydraulic principle gives a great number of advantages:
* Fast mounting/dismantling. Only one screw needs to be tightened.
* Extremely good concentricity, also after several mountings.
* Can be mounted/dismantled 1000\' s of times.
* Possible to mount in tight spaces. The pressure screw is tightened in the radial direction to the shaft.
* Small built-in dimensions.
* The hub can be adjusted easily and accurately.
