The CENTAFLEX design X is a variant of the proven and successful CENTAFLEX system.

The following types are wellknown since long:

  • the highly flexible CENTAFLEX design made of rubber

  • the torsionally relatively stiff design H made of polyes- terelastomer for Diesel hydraulic drives.

    These are joined by the torsionally stiff design X, which incorporates the following proven parts and principles of the above mentioned design types:

    • hubs made of high quality steel, precision machined all over, suitable for a multitude of applications

    • alternate axial and radial screw connection of the flex- ible element to the hubs by means of self securing high tensile fasteners.

      A special feature of the design type X is the slender ele- ment made of a newly developed extremely tough and highly stressable plastic.

      This element is torsionally very stiff, free from play, but has bending elasticity and is flexible in angular and axial directions. Moreover, it is oil resistant and withstands temperatures up to 150° C.

      The radial bushes are firmly injection moulded into the element.

Die CENTAFLEX-Bauform-X ist eine Variante des bewähr- ten und erfolgreichen CENTAFLEX-Systems.

Bekannt sind seit langem:

• die hochelastische CENTAFLEX Bauform aus Gummi

• die relativ drehsteife Bauform-H aus Polyesterelastomer für diesel-hydraulische Antriebe.

Dazu kommt die drehsteife Bauform X. Von den beste- henden Ausführungen wurden für die Bauform X folgen- de, bewährte Teile und Prinzipien übernommen:

  • Naben aus hochwertigem Stahl, allseitig präzise bear- beitet, vielseitig abwandelbar.

  • Abwechselnd axiale und radiale Verschraubung der flexiblen Lamellen mit den Naben mittels selbstsichern- der, hochfester Schrauben.

    Das Besondere an der Bauform X ist die schlanke Lamelle aus einem neu entwickelten, extrem zähen und hochbe- lastbaren Kunststoff.

    Diese Lamelle ist sehr drehsteif, spielfrei, jedoch biege- elastisch und daher axial und winkelig flexibel. Sie ist darüberhinaus ölbeständig und verträgt Temperaturen bis ca. 150° C.

    In dieser Lamelle befinden sich Stahlbuchsen, die abwechselnd axial und radial mit den Naben verschraubt werden. Die radialen Buchsen sind in die Lamelle fest eingespritzt.

The axial bushes are available in 2 versions:

Standard design X

The axial bushes are firmly pressed into the element, which makes this design axially movable only within close limits, namely within the limits of the elasticity of the ele- ment. This coupling can transmit axial forces.

Design X-S

Die axialen Buchsen gibt es in zwei Versionen:

Normalbauform X

Die axialen Buchsen sind fest in der Lamelle eingepreßt.

Diese Bauform ist daher nur in geringen Grenzen, nämlich im Rahmen der Elastizität der Lamelle, axial beweglich. Diese Kupplung kann Axialkräfte übertragen.

Bauform X-S

The axial bushes are free to slide axially in the element.

The design type X-S therefore is axially freely movable, it is a plug-in type and free from axial forces, provided there is axial play. It is used for fitting in closed hous- ings where blind fitting is necessary and especially where greater axial movement is required.

With the introduction of the torsionally stiff element of the series X design, and using existing construction parts, the CENTAFLEX system is most economically extended to new areas of application, e.g. pump drives (especially with radially removable spacer pieces), cooling tower drives, air conditioning, printing machines, packaging machines, step motors, tachometer drives, hydraulic drives, com- pressor drives. 

Advantages and Features

  • Simple, compact, smooth-face design

  • Low weight, low inertia

  • High performance, high permissible speed, large per- missible bores, rupture-proof

  • The torque is transmitted absolutely evenly and free from play

  • The coupling is free of maintenance

  • The element is airflushed all around, the heat generated is easily conducted away and it remains cool

  • The elements can be dismantled transversely without any axial displacement

  • By slackening the axial screws, the drive can easily be disconnected and rotated without dismantling

  • No axial reaction forces are imposed on the shafts and bearings as a result of the transmissions of torque.
