Inkoma KWK Inkocoss couplings from Francis and Francis
In this coupling, two steel pins act as circular planular keys, locked into shallow grooves, cut at 90° to each other, on either side of the central steel disc. Each pin also slots radially into a deep circular-section, low friction, bushed groove, across the inner face of the two steel end-hubs, enabling large radial and angular movements.
>As the bushed groove, circular-section, in both end-hubs exceeds 180°, all 3 coupling discs are axially retained, within a tight tolerance; thereby making the design ideal for precise transmission of axial push-pull actions, as well as a torsionally stiff rotary drive connector.
>With its free-pivoting around - and easy-slide radial movement along-the 90° 'crossed' pins, between the two end-hubs and with minimal side/support-bearing loading, or misalignment restoration forces, other than from the central disc centrifugal mass, it also offers true constant velocity, good fail-safe, high torque transmission, whilst mounting and removal are simply achieved.
>Typical applications include: valve actuation, pick-and-place and printed circuit board machines, screw jacks and cylinder/piston action connections.
>Shaft connections are via flange as standard, or bossed end discs.
>The Range accommodates normal torques (TStat) up to 13,000Nm, for shaft diameters up to 160mm and maximum offsets up to ±15mm and angular misalignment up to ±3° (at low speeds).
