Flange coupling FL-SP

torsionally rigidcompactsteel

General description
The flange coupling FL-SP is developed for hydrostatic pump drives to connect internal combustion engines with hydraulic pumps. Its torsionally stiff design shifts critical resonances above the operating speed, enabling sub-critical operation without passing through damaging torsional vibration amplitudes. The FL-SP is compact, axially pluggable and suited for installations with limited axial space.

Design and construction
The FL-SP coupling consists of a clamping hub and a plastic-steel composite flange assembled as an axial plug-in connection. The clamping hub provides a backlash-free connection on the pump shaft. The coupling flange is available in various SAE sizes. REICH supplies pump mounting plates to attach hydraulic pumps to engine housings. Customized solutions can be developed under the D2C (Designed to Customer) principle.

Advantages

• Torsionally stiff design allows sub-critical operation and avoids resonance crossing
• High torque transmission capacity for a wide range of applications
• Compact and axially pluggable construction for restricted installation spaces
• Compensation of axial, radial and angular displacements reduces assembly effort and improves operational reliability
• Backlash-free shaft-hub connection prevents pump-shaft wear and ensures smoother operation
• Axial plug-in design enables fast installation and short repair times
• Multiple spline options for pump-shaft connection; finish bore with keyway possible
• Operating ambient temperature range from -20 °C to 100 °C
• Pump mounting flanges available for nearly any installation situation

Standard types / Product variants

• Type D2C "Your design" — couplings developed individually to customer requirements
• Modular components enable efficient and cost-effective customer solutions
• Close cooperation with partners: consulting, development, design, manufacturing and integration
