Geislinger Flexlink

Coupling Designation

Example: GFL S 63 F 8A GFL: Geislinger Flexlink S: Series 63: Size F: Type 8: Number of links A: Axial support Technical data for each coupling can be selected from the technical data sheets depending on size, series and number of links.

Nominal Torque

KN The mean torque
T is calculated from the engine power
P and rotational speed

-1 The coupling size should be selected so that the coupling's nominal torque
T KN is greater or equal to the mean torque
T specified by the prime mover / application.
KN

TT

It is not recommended to choose an oversized coupling however, in combination with a Geislinger Coupling, the nominal torque of the Geislinger Flexlink should be equal or greater than that of the Geislinger torsional elastic Coupling

Permissible Vibratory Torque

T

v In addition to the static nominal torque
T KN , the coupling can also transmit a vibratory torque. The limits for vibratory torques
T v both under transient and continuous conditions are shown in diagram 1. Smaller engine mean torques
T allow for greater vibratory torques
T v . The limits shown in the diagram 1 should not be exceeded, not even during cylinder misfiring.
