Fluid Coupling for Internal Combustion Engines KFBD - SKF

Product catalog summary
Introduction
Transfluid Fluid Couplings are designed for use with internal combustion engines up to 2300 kW, enhancing performance and protecting machinery by transmitting power through fluid.
Performance Characteristics
Fluid couplings operate by allowing a slip between input and output, which is represented by performance curves. At 100% governed speed, slip is 1.5%. The coupling allows engines to deliver maximum torque without stalling, ensuring smooth power transmission and easy engine starts under low load conditions.
Advantages of Fluid Couplings
  • Prevents engine stalling during heavy starts by allowing slip.
  • Eliminates mechanical connection, providing a cushioned drive.
  • Dampens torsional vibrations, extending transmission life.
  • Protects equipment by smoothing shock loads.
  • Ensures full input torque transmission.
  • Balances load distribution in compounded drives.
SKF Series Installation
SKF type installations require specific designs and certified instructions from the technical department. Dimensions are subject to change without notice.
Technical Specifications
Includes detailed dimensions and specifications for various sizes of fluid couplings, such as KFBD and KRDA, with notes on keyway standards and optional temperature switches.
Product Applications
Fluid couplings are suitable for a wide range of applications, including tractors, pumps, compressors, fans, marine propellers, and more, with power ranges from 15 to 3500 kW.

Fluid Coupling for Internal Combustion Engines KFBD - SKF-2

FLUID COUPLINGS FOR INTERNAL COMBUSTION ENGINES Applying TRANSFLUID Fluid Couplings in your Drive Line Transfluid Fluid Couplings are used on all types of industrial equipment driven by internal combustion engines up to 2300 kW. By transmitting power through a fluid, they improve overall performance and protect both driving and driven machine. Figure 1 shows the typical performance available from a Fluid Coupling when used with an internal combustion engine. The curved sloping lines represent the torque capacity of Fluid Coupling for various values of slip and input speeds. The relatively flat...

THE ADVANTAGES OF FLUID COUPLINGS When you drive through a Transfluid Coupling you profit by these Basic Benefits Frees engine during heavy starts During heavy starts and sudden running load increases, engine stalling is prevented. The Fluid Coupling simply “slips” while the engine smoothly picks up the load. 2 Provides cushioned drive Mechanical connection is eliminated; power and torque are transmitted entirely by the mass and velocity of the fluid. The result is a smooth, sustained flow of power without the shocks and strains which, with mechanical drives, reduce equipment life. 3 Prevents...
