KBK Servo Insert Couplings

Servo Insert Couplings are coupling types which should be used in applications where vibrations and

crushes may appear. The dampening attributes of those couplings are caused by the spider element

which is positioned between the two hubs. This spider element is available in different shore –

hardnesses. Depending on the requirements it is proposed to use a spider element with low dampening

properties for applications with low vibrations and crushes (higher torsional stiffness of the coupling)

and to use a spider element with high dampening properties for application with high grades of

vibrations or crushes (lower torsional stiffness of the coupling).

A further positive property of the servo insert couplings is that they are pluggable, so those types can be

assembled quickly and easily even under difficult assembly conditions. The possible varieties of the hub

style include shaft fixing with set screws, with clamp hubs and with outer conical hubs. As you can find

it with other coupling types too, the version with clamp hubs is the most popular with the servo insert

couplings as well because they ensure the fastest assembly/ disassembly without leaving trays on the

shafts.

A misalignment of the shafts in axial, lateral and angular directions can be compensated by a servo

insert coupling as well but it should be only a minimum of misalignment because relatively high reset

forces are caused by the coupling which do negatively influence the lifetime of the components like

bearings in the environment.

For compensating higher misalignments it is proposed to use different kinds of couplings, like a metal

bellows coupling.
