SYPT H-EUPEX high flexible couplings are for shaft connection of machines,they compensate for shaft misalignment,generating only low restorative forces.
The torque is conducted through elastomer flexibles, so the coupling has typically flexible rubber properties.
The flexible inserts of the H-EUPEX coupling are subjected to compression. If the flexible inserts are irreparably damaged, the hub parts come into contact with metal. This “emergency operation capability” is required, etc., in the case of fire pump drives.
The motor torque is transmitted to the hub at the drive end via the shaft-hub connection, which is mostly designed as a keyway connection. The torque is transmitted to the hub on the output side with the aid of elastomer flexible inserts. The hub on the output side further transmits the torque to the driven machine or a gear unit placed in between. Because of the primarily compressionloaded elastomer flexible inserts, the coupling has a progressive torsional stiffness.

Materials Used in Manufacturing Gear Couplings
Gear couplings are designed to transmit torque between shafts while accommodating misalignment. To ensure the durability and reliability of gear couplings, manufacturers use a variety of materials, each with its specific properties. Commonly used materials in manufacturing gear couplings include:
- Steel: Steel is the most widely used material for gear couplings. It offers excellent strength, durability, and resistance to wear and fatigue. Steel gear couplings are suitable for a wide range of applications, including heavy-duty industrial machinery.
- Stainless Steel: Stainless steel is chosen for gear couplings that require resistance to corrosion and high-temperature environments. Stainless steel couplings are commonly used in food processing, pharmaceutical, and chemical industries.
- Alloy Steel: Alloy steel is utilized to enhance specific properties, such as increased strength and improved performance under high loads and extreme conditions. Alloy steel gear couplings are ideal for demanding applications in heavy industries.
- Cast Iron: Cast iron is known for its excellent machinability and good resistance to wear. Cast iron gear couplings are suitable for low to moderate torque applications and can be cost-effective in certain scenarios.
- Non-Metallic Materials: In some cases, non-metallic materials like nylon or urethane may be used for specific gear coupling applications, especially in situations where electrical isolation or chemical resistance is required.
The choice of material depends on the application’s demands, including the torque, speed, environmental conditions, and budget considerations. Gear coupling manufacturers carefully select materials that will provide optimal performance and longevity while meeting the specific requirements of the intended application.
