Jaw couplings are an economical way to connect electric motors to uniform and properly aligned loads. Each coupling consists of two identical hubs and a cam ring of elastomer element. The cam ring provides torsional flexibility to rotating shafts and protect the motor and load from rotational shocks. Elastomer elements are usually considered the consumable part of the coupling and can be replaced at lower cost compared to replacing the complete coupling. It is essential to use the jaw-type coupling in applications with negligible axial loads to avoid the separation of the two hubs during operation. Hubs can be either in finished or tapered bores. Tapered bore hubs are more convenient for maintenance as there are no need to axially move the motor nor the load to replace the flexible elements. Jaw couplings are Fail safe which means that they can work at emergency situations even when the flexible elements are worn out. The German Manufacturer “Flender” supply BIPEX jaw coupling with Pilot or finished bore BWN, or tapered Bore BWT with both A and B variants depending on the direction from which taper clamping bush is inserted. The taper clamping bush is fitted from the machine side if hub part 4 used in BWT type. On the other hand, if hub part 3 used, the clamping bush if fitted from the shaft end face side. BIPEX are usually used to connect electric motors with pumps, compressors, cranes, or bell housing installation. The hubs are made of cast Iron EN-GJL-250 and the standard cam ring is made of PU 92 ShoreA -30 to 80 degrees Celsius. https://optimalpart.com
