Can an Euroflex coupling be used in vertical operation?
Euroflex disc couplings can be used in vertical operations and generally do not require a support. Even though a disc coupling when suspended in vertical mode will experience sag of the spacer section directly proportional to the stiffness of the two flexing elements taken in parallel, the degree of this sag will very with the coupling size, design, length and weight of the spacer section. However since the axial stiffness of the disc coupling increases with speed, the level of sag will consequently reduce as the unit begins to operate. The Euroflex coupling design takes into consideration the resulting stresses caused by the imposed sag. However if the spacer section is too long or heavy and there is a need for a support to be introduced, then the Euroflex design practice is to provide spherical buttons as shown in the figure. These buttons are placed at the central point of the flexing element, to ensure that any angular misalignment causes rolling of the surface and not rubbing.
