  • Examples

    Example 1: Blade wheel fixture with two clamping sleeves type IK

    Die auf breiter Basis angeordneten Spannelemente wirken sich günstig auf die Planlaufgenauigkeit und die Umlaufbiegebeanspruchung des Welle-Nabe-Verbundes aus.

    The clamping sleeves arranged over a wide basis exert a positive influence on run-out accuracy and rotating flexural stress of the shafthub fit. The degree of torque which can be transferred with two consecutively arranged clamping sleeves is approx. 30 % higher than when using a single clamping sleeve.

    Example 2 – 4: Plug-in connections

    This shaft-hub connection is completely free of play and can be released an unlimited number of times. The tightening torque levels for clamping force initiating screws depend on the required clamping force for each individual clamping sleeve.

    Example 2

    Spanneinleitung auf ein IL Spannelement über Zugschraube.

    Clamping sleeve type IL with clamping force initiated by tension screw.

    Example 3

    Spanneinleitung auf ein AL Spannelement über Druckschraube.

    Clamping sleeve type AL with clamping force initiated by set screw.

    Example 4

    Spanneinleitung auf ein AL Spannelement über Hohlschraube.

    Clamping sleeve type AL with clamping force initiated by hollow screw.

     

    Example 5: Spindle sleeve clamped by two clamping sleeves type AK

    Hydraulisch wird die Pinole genau zentrisch gespannt, im drucklosen Zustand ist sie sofort frei bewegbar.

    The sleeve is hydraulically tensioned and precisely centred. Free movement is immediately possible in the un-tensioned state. The axial thrust created during the clamping process with single arrangement of a clamping sleeve is theoretically balanced out in this case by forces working in opposition. In practice, however, in case of a freely located sleeve, allowance must be made for a slight residual thrust as it is not possible to create identical clamping conditions at the clamping sleeves.

    Example 6: Bevel wheel fixture by clamping sleeves type IK

    Kegelradbefestigung mittels IK Spannelementen

    This connection is characterized by simple connecting components, a high degree of concentricity and absolute freedom from play.

    Example 7: Pulley fixture by clamping set type DSM

    Zahnriemenscheibenbefestigung durch einen Spannsatz Baureihe DSM

    The hub can be made of an aluminium alloy. Observe the minimum strength specification. High temperatures can impair retention force.

    Example 8: Indexing plate clamped with a clamping set type DSM

    Teilteller befestigt mit Spannsatz Baureihe DSM

    Indexing plate in alloy material at the shaft end of an indexing gear. Here, precise concentricity and run-out are vital.

    Example 9: Gear fixture by clamping set type DSL

    Zahnradbefestigung durch einen Spannsatz Baureihe DSL

    To satisfy the highest concentricity requirements, we recommend mounting a control facility on the gear to allow the concentricity to be checked and adjusted if necessary.

    Example 10: Pressure roller fixture by using two clamping sets type DSL

    Druckwalzenbefestigung mit zwei DSL Spannsätzen

    Here, two long clamping sets are used to achieve high overall radial rigidity due to intensive tensioning of the shaft and hub. The pressure roller is exchanged by pulling the shaft out of the bearings.

    Example 11: Rocker arm fixture by using a clamping set type DSK

    Schwinghebelbefestigung mit einem Spannsatz Baureihe DSK

    The peripheral and axial position can be ideally adjusted during assembly.

    Example 12: Guide column clamped with a clamping set type DSL

    Führungssäule geklemmt mit einem Spannsatz Baureihe DSL

    Fixture of a guide column in the machine body.

  • Benefits

    Competitiveness through technological leadership – a strategy that calls for an economical increase in power density, efficiency and accuracy. Cylindrical clamping sets create the foundation for this.

    Lower Resource Input

    • Simple configuration of connecting components.
    • Simple installation and dismantling of all components thanks to mating play.
    • Minimum axial drag during clamping process.
    • Clamping force initiation can be freely configured.
    • Quick-release connection.

    More Success

    • High level of concentricity.
    • Minimised vibrational excitation.
    • High torque levels and axial forces.
    • Suitable for alternating torsion.
    • Axial and angular position freely adjustable.
    • Preserves connecting components.
    • Connection can be automated/switched.
    • Re-usable.

    Four unique features – numerous benefits

    • Precise
      All functional surfaces that determine precision are machined to the finest geometrical and positional tolerances.
       
    • Single-piece design
      Unlike tapered clamping sets, the single-piece steel body does not have any joints that could compromise tolerances. This ensures that the high degree of precision achieved in the manufacturing process can also be brought to bear in the relevant application.
       
    • Self-centering
      When subjected to axial compression, the unique geometry of the absolutely symmetrical base body ensures uniform transverse contraction in the direction of the shaft and hub. The resulting centring effect is equivalent to that of the hydro-expansion principle, only much simpler, safer and stiffer.
       
    • Intelligent
      Cylindrical clamping sets exert very low levels of wear on their connecting components. Significantly better clamping homogeneity at the contact surfaces eliminates any possibility of peak clamping force acting at specific points, which frequently lead to damage and installation problems. At the same time, the Spieth design in the tensioned state is equivalent to the combination of a knee lever and a spring compressed against a block, thus guaranteeing an extremely rigid connection. And when released, the cylindrical clamping set easily returns to its original shape.
  • Function

    Functional principle

    Shown here is the using of a clamping set from series DSK with an integrated clamping screw.
    The principle is illustrated in a simplified diagram with enlarged play.

    Clamping set released, easy installation or dismantling with mating play.

    Clamping set clamped, connection is centred with a high load capacity. No lateral displacement during tightening. This ensures ultrahigh precision centring and optimum concentricity.

  • Transmittable Forces

    DSK / DSL / AK / IK / AL / IL

    The specifications provided in the table apply to a bore tolerance of H7 and a shaft tolerance of h5 in the connecting components. For an h6 shaft, in the most unfavourable scenario, a reduction of transmittable forces of approx. 10 % may be expected.

    DSM
    The specifications provided in the table apply to a bore tolerance of H7 and a shaft tolerance to DIN 748 (k6/m6).

    M: Transmittable torque at Fa = 0
    The specified values were ascertained in a series of tests, in which the connecting components were made of C45 steel, produced with the stipulated surface quality.

    The specified performance data are subject to the variation of the friction values of the different contact partners. The components are designed to be reusable, with frequent assembly and disassembly we recommend reducing the tightening torque. Please note that this can also reduce the transmissible torque.

    Fa: Transmittable axial force at M = 0
    The Fa values are calculated according to

    Subjection of the clamped connection to steady, pulsating, alternating or sudden stress has no impact provided that the occurring peak forces do not exceed the catalogue values. The risk of fretting corrosion is always a possibility in friction-locked connections subjected to alternating torsion or rotating bending stress. This phenomenon can complicate dismantling and can be prevented by complying with the following instructions:

    Perm. alternating torsion

    Perm. rotating bending stress

    M and Fa:
    If both torque and axial forces act on a clamping set at the same time, check using the following formula whether the resulting torque Mr is transmittable.

    M = Transmittable torque (catalogue value) [Nm]

    Me = Required torque [Nm]

    Mr = Resulting torque [Nm]

    Fae = Required axial force [N]

    d1 = Shaft diameter [mm]

    For series AK/IK, AL /IL only

    F: Maximum permissible clamping force
    To avoid the danger of fatigue failure and fretting corrosion, the clamping sleeves should be tensioned in case of high clamping/release cycle frequencies to a maximum of 0.75 F.

    C: Required functional installation space
    Spieth clamping sleeves must be clamped using the controlled application of force. The clamping force cannot be applied in relation to the clamping path. To prevent premature blocking, a "free" functional path "C" must be provided.

    Automated operation
    In the case of automated operation, for example, using hydraulic actuation, a variety of influencing variables can cause the actual values of the system to deviate from the catalogue values. For this application scenario, we strongly recommend that you verify the force or torque values required. In this application, care must be taken to ensure that the installation is completely free of axial play. To avoid fatigue failure and due to the danger of fretting corrosion, in case of high clamping/release cycle frequencies, the clamping sleeves should be tensioned at a maximum of 0.75xF.

    General
    If it is not possible to apply the clamping force F, the following formula is used for approximate determination of the torque Mred which can be transmitted with the given clamping force Fgiv. (<F).

    To ascertain the necessary clamping force for a transmittable torque Mred < M an approximation is possible using the following formula:

    M = Transmittable torque (catalogue value) [Nm]

    Mred = Reduced transmittable torque [Nm]

    F = Max. perm. clamping force (catalogue value) [N]

    Fae = Required axial force [N]

    Ferf = Required clamping force [N]

    Fgeg = Given clamping force (<F) [N]
