Ondrives develops servo-insert couplings
An
Ondrives product story
Edited by the Engineeringtalk editorial team
Jun 24, 2009
Ondrives has recently introduced a range of servo-insert couplings into its extensive coupling range via its biggest ever catalogue, after merging with sister company, Rino Industries.
Typically, the couplings are used in applications where vibrations and crushes may appear.
The dampening attributes of those couplings are caused by the spider element that is positioned between the two hubs.
This spider element is available in different shore hardnesses.
Depending on the requirements it is recommended 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 with high grades of vibrations or crushes (lower torsional stiffness of the coupling).
A further feature of the servo-insert couplings is that they are pluggable, so they can be assembled quickly even under difficult assembly conditions.
The many different varieties of the hub style include shaft fixing with set screws, with clamp hubs and with outer conical hubs.
The most popular type is with the clamping hubs as they ensure the fastest assembly/disassembly without leaving marks on the shafts.
Torque range varies from as low as 1.2Nm up to 940Nm on the largest sizes.
Other features include an extremely compact design and minimum mass and inertia as standard.
They offer high resistance against environmental influences and temperatures as well as being non-wearing and therefore maintenance free.
A misalignment of the shafts in axial, lateral and angular directions can be compensated by a servo-insert coupling as well, but it should only be a minimum of misalignment because relatively high reset forces are caused by the coupling that negatively influence the lifetime of components such as bearings in this environment, the company said.
Typical applications include: stepping motors, servo drives, machine tools, CNC machines, wood working and packaging machines, factory automation machinery, printing machines, sheet metal forming machines, industrial robots, textile machines, plus control and feedback control systems.
