POWER TRANSMISSION LEADING BY INNOVATION SB-SC-SD-SE TORSIONALLY HIGHLY ELASTIC COUPLINGS FOR DIESEL ENGINES HOCHDREHELASTISCHE KUPPLUNGEN FÜR ANTRIEBE MIT DIESELMOTOREN
Open the catalog to page 1These torsional highly elastic CENTAMAX couplings were first introduced in 1980. Since that time they have been proved in numerous difficult applications. Diese sehr drehelastische Kupplung wurde 1980 von der Firma CENTA Antriebe entwickelt und auf den Markt gebracht. Sie hat sich seitdem in tausenden schwierigen Einsatzfällen bestens bewährt. This coupling has been developed and tested following intensive research, calculations and market studies for the following areas of application: Drives subject to torsional vibration especially diesel engi ne drives, where the driven components have...
Open the catalog to page 2For generator sets the following characteristics of the CENTAMAX couplings are very advantageous: Bei Generatorantrieben sind folgende Eigenschaften der CENTAMAX Kupplungen besonders vorteilhaft: • Suited for blind-fitting when set is flange-mounted. • Steckbar: bequeme Montage bei geflanschten Generatoren. • Free of backlash, even after long service time, therefore no creation of noise at idling or low load conditi ons. • Spielfrei: auch nach längerer Laufzeit, keine Geräuschbildung durch Drehschwingungen bei Leerlauf oder geringer Teillast. • Linear characteristic, that means resonances...
Open the catalog to page 3CE Important characteristics and advantages Wichtige Eigenschaften und Vorteile: • Torsionally very soft, no backlash. • sehr drehelastisch, spielfrei • Linear characteristic. • Torsional stiffness can be adjusted by choice of differ ent Shore hardness discs. • Temperature resistant. • Dampens vibration and shock loads, accepts axial, ra dial and angular misalignment. • Good heat dissipation due to special airflow over disc. • Suitable for high speeds. • Hub accepts large bores. • No wearing parts, long life, reliable, maintenancefree. • Compact, slim design, input flange dimensions to...
Open the catalog to page 4CENTAMAX couplings can be supplied in accordance with the requirements of the leading classification societies. However, if this is required, it must be specified at the time of the initial enquiry and when ordered. The cou plings have general type approval from many important societies. Please ask for details. If required, a „fail-safe“ design of the coupling can be sup plied (Page 18, figure 2). Die Kupplungen können gemäß den Klassifikationsvor schriften der verschiedenen Klassifikationsgesellschaften geliefert werden. Von den wichtigsten Gesellschaften liegt außerdem die allgemeine...
Open the catalog to page 5Flywheel — Shaft Type SB — Sizes 120–2400 Verbindung Schwungrad – Welle Bauform SB — Größen 120–2400 The driven inner hub consists of two pieces, the vulcanized steel ring and the inner steel-boss. Die innere Abtriebsnabe ist zweiteilig ausgeführt, sie besteht aus dem einvul kanisierten Stahlring und der eigentli chen inneren Stahlnabe. These two parts are bolted together and the drive is transmitted by the friction force created by the axial bolts, drawing the tapered hub onto a mating taper in the element. This connection is very conservatively dimensioned but it can be easily disas...
Open the catalog to page 6This type is comprised of 2 rubber ele ments - parallel acting - which are bolted to the hub in order to double the torque capacity. This version is basically possib le for the sizes 2800, 4000, 8000, 12000 and 18000. Bei dieser Bauform werden 2 Gummie lemente - parallel angeordnet - mit der Nabe verschraubt, um das übertragbare Drehmoment zu verdoppeln. Diese An ordnung ist grundsätzlich möglich für die Baugrößen 2800, 4000, 8000, 12000 und 18000. Types SBE, SCE and SDE Sizes 240–18000 Flywheel - shaft connection Bauform SBE, SCE und SDE Größen 240–18000 Verbindung Schwungrad – Welle...
Open the catalog to page 7CE Types SBEW, SCEW, SDEW Radial assembly/disassembly types for shaft-to-shaft drives Sizes 240–18000 Bauform SBEW, SCEW und SDEW Größen 240–18000 Verbindung Welle – Welle This type is for the connection of 2 shafts where the element can be removed radi ally without disturbing the driving or dri ven shafts. Here single cylindrical steel bolts are used instead of the aluminium teeth in the outer ring which engage with the toothed rubber disc, exept on the size 8000 SDEW (with double ele ments) where an outer aluminium ring is used. Diese Bauform dient zur Verbindung von 2 Wellen, und sie...
Open the catalog to page 8The following well-known formula can be used for the pre liminary coupling selection, based on transmitted torque: Eine überschlägige Zuordnung, ausgehend vom zu über tragenden Drehmoment, kann zunächst nach folgender bekannter Formel erfolgen: P T = n 9550 · Provided that: T < TKN· St1 P = Power [kW] n = Speed [rpm] T = Transmitted torque [Nm] TKN = Nominal torque of coupling [Nm] In closed flywheel housings there is always an ambient temperature of at least 60°C - 70°C. For reliable coupling selection on drives subject to tor sional vibration (diesel engines, piston compressors etc.)...
Open the catalog to page 9CE The CENTAMAX couplings are robust and reliable, but with the wrong torsional situation every coupling, and possib ly the whole power train, is in danger. Therefore it is of the utmost importance to ensure that torsional vibration calculations are made at the beginning of the coupling selection procedure. Die CENTAMAX-Kupplungen sind robust, aber bei falscher Drehschwingungslage ist jede Kupplung gefährdet, unter Umständen der gesamte Antriebsstrang. Darum ist es so wichtig, die Drehschwingungslage zu berechnen und von Anfang an eine geeignete Kupplung vorzusehen. The technical data on...
