Chesterfield based mechanical components supplier, Ondrives has introduced a range of servo-insert couplings into its coupling range.
 Typically, they are used in applications where vibrations and crushes may appear. The dampening attributes of the 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, Ondrives recommends customers 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 of high grades of vibrations or crushes (lower torsional stiffness of the coupling).
A further property of the couplings is that they are pluggable, so they can be assembled under difficult assembly conditions. The varieties of the hub style include shaft fixing with set screws, with clamp hubs and with outer conical hubs.
Torque range varies from 1.2 up to 940Nm and according to Ondrives they offer high resistance against environmental influences and temperature.
Typical applications range from stepping motors, servo drives and machine tools, to factory automation machinery, printing machines and industrial robots.
