The coupling types set up for shaft-hub connections with Taper clamping bushes are designated as follows: » VariantA: Coupling with part 3 – part 3 » Variant B: Coupling with part 4 – part 4 » VariantAB: Coupling with part 3 – part 4 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.
