© Siemens AG 2015 FLENDER Standard Couplings Highly Flexible Couplings — ELPEX-B Series General information ELPEX-B coupling types EBWN Coupling as a shaft-shaft connection with drilled and grooved hubs EBWT Coupling as a shaft-shaft connection with Taper clamping bushes EBWZ Coupling as shaft-shaft connection with detachable adapter The coupling types set up for shaft-hub connections with Taper clamping bushes are designated as follows: • Variant A: Coupling with part 3 – part 3 • Variant B: Coupling with part 4 – part 4 • Variant AB:
Coupling with part 3 – part 4 Further application-specific coupling types are available; dimension sheets for and information on these are available on request. In the case of part 3, the Taper clamping bush is screwed in from the shaft end face side. The coupling half must be fitted before the machines to be connected are pushed together. In the case of part 4, the Taper clamping bush is screwed in from the machine-housing side. If there is insufficient room, the Taper clamping bushes cannot be fitted from this side. Besides fitting space for the Taper clamping bush bolts, space for the fitting tool (offset screwdriver) must be taken into account.
In the case of coupling type EBWT, part 3 and part 4 can be combined as required. Furthermore, the variant with a Taper clamping bush can be combined with the finish-drilled hub. Unfitted coupling The elastic tire can simply be slipped over the hub parts. The elastic tire is held firmly in place by fitting the clamping ring. The connection transmits the torque by frictional engagement. Fitted coupling, shown without connecting shafts. 10 Fitted elastic tire 10/3 Siemens MD 10.1 · 2015 Type Description
