AUTOFLEX METAL MEMBRANE COUPLINGS

AUTOFLEX METAL MEMBRANE COUPLINGS The Autoflex Metal Membrane Coupling is designed to provide a highly reliable connection for rotating equipment.The coupling requires no lubrication and thus is maintenance free. Properly installed, the coupling is designed to provide infinite life. Autoflex Advantages Metal membrane coupling construction provides optimum power and misalignment capability Cartridge transmission unit provides for easy assembly while maintaining an inherent balance to AGMA class 9. The Autoflex has an optional design to handle non-standard DBSE* using factory assembled Guard Ring Packs which are bolted to a standard spacer tube. Membranes are made from high strength 301 stainless steel. Hubs have been optimised to provide a larger bore capacity. All steel parts are phosphate coated. ATEX Approval The range of Autoflex Couplings has been approved under ATEX directive 94/ 9/ EC - for use in potentially explosive gas and dust atmospheres. I M2 . II 2 GD The Autoflex membrane has been optimised using finite element analysis.This has resulted in a waisted link design which provides more flexibility and thus substantially lower reaction forces on the bearing of the connected equipment. The stresses through the new membrane design are uniform and are inherently low due to the reduced weight and inertia of the pack.The membranes have been designed to provide for infinite life utilising a safety factor of 2 times on the Modified Goodman Diagram. * DBSE - Distance Between Shaft Ends Reduced windage configuration which also provides an inherent fail-safe feature in the unlikely event of membrane failure. Overload collars also provide an inherent fail-safe feature, protecting the membrane in the event of severe transient torque overloads. Coupling performance is enhanced using high grade washers with an optimised radius profile. Higher grades of dynamic balance are possible through the elimination of balance tools.Gagging is achieved by locking the guard ring to the spacer flange.
