KE Series Elastomeric Couplings The KE coupling is a general-purpose flexible coupling, fully interchangeable with the standard couplings frequently used throughout the industry. The coupling consists of two machined cast iron hubs connected by an elastomeric gear ring. Available in 8 basic sizes, with torque capacity to 3300 Nm, the KE coupling provides positive power transmission between shafts, combined with the ability to accommodate moderate levels of misalignment. KE couplings are designed to transmit torques equal to the capabilities of sizes of commercial shafting which can be accommodated. Available either with parallel bore or with taper bush, these couplings are quick and easy to assemble with the machined outer flanges enabling simple alignment with just a straight edge. The elastomeric gear ring is moulded in Pebax R Polyether which is oil resistant, has a partial resistance to chemicals, and a low moisture absorption rate. The gear ring cushions transient peak torques, effectively reducing transmission of operational vibrations and shock loads. Standard couplings can be operated in environmental temperatures ranging from –40˚C to +85˚C. Refer to page 2 for standard procedure for coupling selection. The number of starts to which an KE coupling is subjected will affect its life, and it is thus necessary to modify the design power Pd for drives subject to more than 4 starts per day by factor f. in table, to get selection power Ps.

KE Series Couplings KE Couplings Dimensions and Technical Specification The KE couplings are available with solid hubs for reworking, ‘type B’; or taper bored hubs for standard taper bushes. The taper bored hubs can be provided with the bush fitting from the hub end, ‘type H’, or from the flange end, ‘type F’, to enable easy fitting to end of motor/gearbox shafts.
