ARPEX ARS-6 series

    Информационные материалы

    Coupling can be designed for potentially explosive environments.

    Область применения

    ARPEX couplings of the ARS-6 series are a versatile coupling solution which thanks to standard modular components can be used for most drive requirements at a low to medium speed. Torques of between 170 and 106000 Nm can be transmitted at a permitted angular misalignment of 0.7°. The open flange form is regarded as very easy to fit and has easily accessible screw connection points. On most types, the intermediate spacer can be radially fitted without moving the connected units.

    Main areas of application for the ARS-6 series:

    • Paper-making machines
    • Printing machines
    • Compressors
    • Pumps
    • Fans and blowers
    • Film and foil machines
    • Generators
    • Presses
    • Metalworking machines
    • Conveyors
    • Crane systems
    • Textile machines
    • Plastics processing machines
    • Centrifuges

    Дизайн

    The classic design of an ARPEX couplings of the ARS-6 series is shown in the following illustration. The plate packs are bolted alternately between the flanges of the coupling hubs and the intermediate spacer. Up to size 280-6 close-fitting bolts and from size 305-6 conical screw connections are used for fastening. A large number of intermediate spacer and shafts, hubs and flanges can be combined and thus cover a large number of possible drive requirements.

    Types

     

    NEN, BEN, BEB

    Variant with standard intermediate spacer, many sizes available from stock

    NON, BON

    Variant with shortest intermediate spacer

    All coupling types can be very easily combined with further standard components in the ARPEX modular system. Jumbo hubs are used to permit larger maximum bores.
    Clamping hubs transmit torque by friction without the use of parallel keys. F, D and C flanges offer many different possibilities for flange connection.

    The coupling parts of the ARPEX ARS-6 series are machined on all sides. Exceptions are H and Z spacers and intermediate shafts. The spacers are delivered with unmachined, primed spacer tube.

    Higher torques and maximum speeds with similar coupling outer diameters DA can be achieved with the ARPEX ARC-8/-10 series.

    Further application-specific coupling types are available in selection module x.CAT at www.flender.com. Dimension sheets and further information are available on request.

    Особенности

    ARPEX couplings of the ARS-6 series are outstanding for their versatility. Most standard components are available from stock, resulting in short delivery times. Their use in potentially explosive environments in accordance with Directive 94/9/EC is possible.

    The permitted shaft misalignments ΔKa, ΔKr and ΔKw are maximum values and must not occur at the same time (see following table).

    The permitted shaft misalignment ΔKr for types NHN, NZN and NWN applies to a coupling with shaft distance S = 1000 mm.

    For other shaft distances the permitted radial misalignment can be determined with the following formula:
    ΔKr = (S – S1) · tan (ΔKw).
    The shaft distance S is shown on the table for the type.

    TKmax permitted only five times per hour.

    The values for torsional stiffness apply to the complete coupling. In the case of types NHN and NZN to a coupling with shaft distance S = 1000 mm. In the case of type NWN, the torsional stiffness applies to a coupling without intermediate or torsion shaft. The torsional stiffness of the plate packs applies to the rated coupling torque TKN. To determine the torsional stiffness for a specific operating point, e.g. for calculating torsional vibration, the manufacturer must be consulted.
