The silent driveshaft The internationally patented CENTALINK shafts are on the market since 1991, more than 10,000 units perform well in severe applications. Many of them have reached more than 50.000 hrs in service without any problems. Die international patentierten CENTALINK-Gelenkwellen sind seit 1991 auf dem Markt, mehr als 10.000 Einheiten haben sich in harten Einsätzen bestens bewährt. Viele davon haben Laufzeiten von mehr als 50.000 Stunden ohne Probleme erreicht. The CENTALINK shaft consists of links which are designed for efficiency using flexible bushes for push and pull. In each...

CE CENTALINK joints offer the following outstanding advantages: Die CENTALINK Gelenkwellen bieten folgende hervorragende Eigenschaften: • compensation for considerable axial, radial and angular misalignment • Ausgleich von großen axialen, radialen und winkeligen Verlagerungen • with very low reacting forces and linear characteristics • Dabei geringe Rückstellkräfte, mit linearer Kennlinie, d.h. proportional zur Auslenkung und fast nicht beeinflußt vom übertragenen Drehmoment • constant velocity transmission, angular deflection of the two joints may be different • silent operation,...

CE Explanation of technical data and selection of CENTALINK Erläuterung der technischen Daten und Auslegung von CENTALINK Nominal torque First the CENTALINK shaft selection has to be based on the nominal torque TKN. This is allowable continuously within the permitted speed range. Under difficult operation conditions additional service factors may be required. For high ambient temperature the temperature factor of St1 has to be considered. Nenndrehmoment Die Auslegung der CENTALINK Gelenkwellen muß zunächst nach dem Nenndrehmoment TKN erfolgen. Dieses ist im zulässigen Drehzahlbereich...

Zulässiger axialer Wellenversatz Der Wert für ∆Ka in der Tabelle der technischen Daten gilt als maximaler Wert für transiente Betriebszustände (z.B. Schock, schwerer Seegang usw.). Bei der Installation der Gelenkwelle sollte der fest vorgegebene, dauernde (statische) axiale Wellenversatz möglichst gering sein, höchstens jedoch 20% vom ∆Ka. ∆Wa ≤ 0,2 · ∆Ka Reaktionskraft bei axialem Versatz: Fa = ∆Wa · Ca (KN) Zulässiger radialer und winkeliger Versatz Bei Gelenkwellen wird ein radialer Versatz immer in einen Winkelversatz umgewandelt. Zusätzlich kann ein winkeliger Versatz der verbundenen...

CE The angle has to be checked at each joint separately and the largest angle α1 or α2 has to stay within the allowable range. The resulting total angle β is not relevant for the selection of the shafts, as long as the two angles α1 and α2 are within their limits. These rules also apply analogously for single joints. The continuously allowable angular misalignment is about 1 degree. However, in the interest of long life this value should be kept as low as possible. For transient conditions (eg. engine starting and stopping, very rough sea etc.) up to 3 degrees are allowable. For shock...

CE Allowable Speed The value in the technical data tables shows the absolute maximum allowable speed. For longer lengths the allowable speed is also limited by the critical speed of the tube and if necessary it has to be reduced. The diagram below shows the limiting values for speed and length of shaft sizes. Each combination of speed and length below the relevant diagonal lines is permissible. e.g. for size 48: n = 1250 rpm, thus: LGmax = 3400 mm. The radial stiffness of the links has hereby already been considered. A further condition is, that the bearings and shafts, supporting the...

If not agreed differently, the CENTALINK-shafts are balanced as follows: a) flanges, flangehubs and inner part to quality Q6.3 b) the links to quality Q16. The links for the CENTALINK consist of forged...

Series Baureihe CL-FF CENTALINK Size CENTALINK Grosse The series FF is the normal series and includes 2 flanges, which can be similar or different in design. Furthermore, if required, standard flanged hubs (page 12) or other special hubs, flanges or adapters can be provided. Die Bauform FF ist die Normalbauform und sie beinhaltet 2 Flansche, die gleich oder unterschiedlich ausgebil-det sein konnen. Dazu kommen dann, je nach Bedarf, Standardflanschnaben (siehe Seite 12) oder sonstige fallspezifische Naben, Flansche oder Adapter. * Die AnschluBmaBe entsprechen der DIN-Norm. Die...

Series Baureihe CL-F0 CENTALINK Size CENTALINK Grosse For series FO a standard flange on one side is intended, while on the other side an existing plain flange can be used. In order to ensure the necessary space for movement is available, the axial bushes are elongated. Thus specially tailored series can be easily designed. * The connecting dimensions are to metric standards. It is important that the value of clamping force is checked to ensure that the torque can be transmitted. If necessary larger standard flanges can be used. When using CENTA flanged hubs the torque capacity is increased...
