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 and to use a spider element with high dampening properties for
application with high grades of vibrations or crushes.
Another advantage of using servo insert couplings is that they are pluggable, so they 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/dismantling without leaving trays on the shafts.
