Product description The INKOMA-PK coupling is machine component designed to transmit torque between axially parallel, radially offset shafts. The coupling permits both static and dynamic stepless adjustment of radial offset within the designed adjustment range. The coupling functions on a parallel crank principle (similar to the traditional draughting mechanism). Each movement at the input is faithfully repeated at the output, without loss or change. No relative motion occurs regardless of the degree of offset, unlike a universal joint assembly. The INKOMA-PK coupling comprises three discs with their faces parallel to each other, connected by at least links. One outer disc is connected to the input shaft and the other to the output shaft. The centre disc provides the connection, via the links, to the outer discs. Features of the INKOMA-PK coupling The INKOMA-PK coupling has synchronous running characteristics; I.e. the input and output run totally synchronously with no angular displacement, regardless of the degree of offset. The INKOMA-PK coupling is dynamically balanced and damps and compensates for radial vibrations imposed from outside the drive. The INKOMA-PK coupling transmits purely torque and therefore imposes no radial loads on related bearings. The INKOMA-PK coupling requires very little space when compared with the offset capability. The INKOMA-PK coupling will tolerate all radial offsets, lying within the designed capability of the coupling. Within the limiting values the radial offset can be freely adjusted whilst transmitting torque loads and at any speed. The angular velocities remain completely synchronous between input and output. Special sizes and designs are possible. Please enquire. 001

Technical information INKOMA-PK coupling is available in the following versions: A1 = Basic version: Both outer discs have fixing holes for socket head cap screws for connecting components. The number of fixing holes on pitch circle "C": Links= x Links= x 5 Links= 5 x 2 6 Links= 6 x A2 = Hub version: Both outer discs have machined hubs. A = Tension hub version: Basic version A1 with additional shrink disc. The shrink disc allows keyless fitting to the shaft. For details of the tension flange see page 18. A = Separable hub version: Basic version A1 with additional adaptor flanges. These flanges have hubs for shaft fitting. For details of separable flanges see page 16. A = Split hub version: This hub version has two components - a fixed and a removable part allowing radial clamping to the shaft. This version requires no axial displacement of the shaft for assembly and disassembly. A1 A2 A A1 A2 A Combinations: Each coupling can combine any of these versions. E.g. A1/A2 - one disc with fixing holes and the other with outward facing bored hub. All versions may be combined with one another, e.g. A/A, A1/A, A2/A Special versions: In addition to basic versions, customer specific executions are also possible e.g. incorporating sprocket, gears, shaft, etc. in the outer discs.

Technical information Notes for installation and operation: The shafts to be connected must have their centre lines parallel to one another. If the specified max. possibible angularity is exceeded the use of an INKOMA-Inkoflex coupling is recommended. (see catalogue Inkoflex couplings). An inclination of the shafts towards each other leads to edge loading of the bearings and premature wear and failure. All have axial freedom: Light series - Plain bearing coupling + 2 mm Standard series - up to size NA 196 ± 2 mm Heavy series - up to size NAS 0 ± mm Ensure that the coupling is not axially tensioned in assembly; the centre disc should feel axially free. Care should be taken to ensure the coupling does not run with the links in tension (stretched). It is possible that the links can be stretched leading to bearing failure. In addition this can lead to the centre disc taking a different sense of rotation when reversing. Max. permitted working offset 0,95 limit of displacement. This should be limited by an end stop. The two outer discs should not be run directly in line. A minimum value of 0, limit of displacement should be maintained. When in line the centre disc is no longer stable. The coupling is supplied ready for use. The needle roller bearings supporting the links are adequately lubricated. Re-greasing can be carried out using grease nipples. Under normal operating conditions the couling is lubricated for life. See page 5 for exceptions. Application examples: There are many applications for the INKOMA-PK coupling. A few typical cases are described below. Drive for rollers: Two related rollers must run synchronously even when the axes are being adjusted for varying products. Haul off: Drives for two haul-off chains used to pull tubes from a process machine. Both chains must run at precisely the same speed and the gap between them must be adjusted to accommodate different tube diameters. Avoidance of conflict: For design reasons the shafts must avoid a conflict. INKOMA-PK coupling provides a simple and space saving solution. Oscilllating drive: INKOMA- are successfully used where both the driving and driven shafts must achieve variations in their position and relationship to each other. To demonstrate the breadth of applications for INKOMA-PK coupling see the following list of machine types.: Filling machines, press lines, printing machines, labelling machines, pleating machines, glass tube drawing, woodworking machines, adhesive sealing machines, roller coating, oscillating drives, paper machinery, roller inspection, actuators, textile machinery, steering systems, packaging machinery, machine tools, cigarette machinery. Despite the most precisie manufacturing procedures and the use of the highest quality materials and bearings a small amount of play is present. In the adjacent diagram empirically derived values for average torsional stiffness are shown. If a complete absence of backlash is demanded we suggest using preloading or drag effects. In most applications the torsional values are adequate. The INKOMA-PK coupling is dynamically balanced and damps and compensates for radial vibrations imposed from outside the drive. 00
Technical information Lubrication for PK coupling: The coupling is supplied ready for operation. Re-lubrication can be carried out using the grease nipples fitted to the links. Re-lubrication frequency depends on the grease characteristics (and grease type), operating temperature, speed, load, amount of grease and environmental conditions. These factors must be observed since they can result in considerable differences. Values for relubrication intervals are expressed in the number of operating hours after which topping up or relubrication is required for that situation. Generally it may be assumed that, in normal operating conditions (moderate loading) life time lubrication is provided.
