AFL / Periflex®VN | Stromag

The flange bearing is a bell that is mounted to the diesel engine. An axially mountable, plug-in, highly flexible Stromag Periflex® disc tyre arranged inside the bell transmits the torque from the flywheel to the cardan shaft.

The disc tyre has a linear spring characteristic and ensures the balanced torsional vibration behavior of the system, while the integrated bearing transmits the cardan shaft’s reaction forces to the engine housing via the bell. This means that the crank shaft bearings are not exposed to the reaction forces. As a rule, the AFL can be use up to a deflection angle of 10°, larger deflection angles are possible on request, depending on the operating conditions.

The bell’s connecting dimensions to the engine housing are based on SAE standard J617. The connecting dimensions to the flywheel on the engine side primarily conform to SAE standard J620 or DIN 6281.

Application

  • The Highly Flexible Couplings for Cardan Shafts is designed for applications with piston engines. The outer part can be bolted directly to the flywheel of an engine. The cardan shaft is flange mounted to the B-side of the coupling.
  • Other application fields are railway industry and engine test cells.

Product Features

  • Highly flexible rubber disc coupling with a linear characteristic for connecting a cardan shaft directly to a diesel engine.
  • Deflection angle of the cardan shaft of up to 10°.
  • The radial and axial forces generated by the cardan shaft are absorbed by an integrated bell housing and transmitted to the engine housing.
  • Torque range between 1000 Nm to 20.000 Nm.
