Backlash-free, torsionally stiff and maintenance-free steel lamina coupling
High displacement figures
Nominal torque up to 280,000 Nm
Operating range up to 280° C
Standard range up to shaft diameter 400 mm
RIGIFLEX® couplings are used on such applications which require a reliable and maintenance-free torque transmission with shaft displacement at the same time. The laminas are waisted lamina sets arranged in layers. They are connected to the hubs or flanges, respectively, in an absolutely backlash-free fit by means of positive-locking set screws.
RIGIFLEX® laminae are waisted laminae sets arranged in layers. They are connected to the hubs or flanges, respectively, in an absolutely backlash-free fit by means of positive-locking set screws. The number of the layers of individual laminae allows to vary torques, displacement figures and stiffness for special designs.
Since our main idea with the development of RIGIFLEX® couplings was to comply with the standards of API 610 and API 671, the spacer is secured by a safety catch, too. In case that the laminae break the spacer remains within the coupling.
In general the removable part is supplied along with a laminae set preassembled by the manufacturer.
