HR 07

Product catalog summary
Overview: The document provides detailed technical information about DESCH HRC flexible couplings, designed for reliable shaft connections in machinery. These couplings are noted for their durability and resistance to wear, oil, ozone, and temperature variations. They effectively absorb impacts, rotary vibrations, and noise.
Specifications: DESCH HRC couplings come in various types, including standard, taper-bush, and combined types. They are engineered to handle radial and axial movements, ensuring that no damaging axial forces impact machine bearings, even with alternating torque. The couplings are fail-safe up to the fracture moment of the cast iron transmission cam, ensuring maximum operational safety.
Installation and Maintenance: These couplings are plug-in type, requiring no rigorous alignment accuracy, making them easy to install. The taper-bush system facilitates fast and easy installation, even with greater shaft tolerances, ensuring a backlash-free and axial fixing of the shaft. The coupling star can be replaced without disassembling the connected machines.
Technical Data: The document includes tables with technical data such as maximum shaft misalignment, rotational speed, torque, torsion spring rigidity, moments of inertia, and weight for different sizes of couplings. The balancing quality complies with DIN-ISO 1940, quality range G 16.
Applications: DESCH HRC couplings are utilized across the entire field of machine construction wherever a reliable shaft connection is needed between a motor and working machines.

Flexible HRC-couplings Standard coupling Taper-bush type combined type standard/Taper The flexible DESCH HRC coupling is a break-through safe claw coupling with flexible element to provide a torsionally flexible connection for shafts. The efle- xible element, the coupling star, excels in its wear resistance, its oil, ozone and ageing resistance and its tempera- ture resistance from -20°C to + 80 °C. Thanks to the coupling's flexibility, impacts, rotary vibrations and noises are effectively absorbed. The coupling star is dimensioned such that radial and axial movements between the two halves of...
