Coupling
Double Diaphragm Coupling is a high-performance flexible coupling that utilizes two parallel sets of metal diaphragm assemblies. Its core consists of high-strength stainless steel diaphragm packs connected to both hubs via precision bolts, leveraging the diaphragms' elastic deformation to compensate for axial, angular, and radial misalignments. The symmetrical design of the two diaphragm sets effectively cancels out additional bending moments in the center spacer, providing higher transmission accuracy.
This coupling features zero backlash, high torsional stiffness (up to 10,000 N·m/rad), and excellent fatigue resistance, with a torque capacity reaching 50,000 Nm and maximum speeds of 12,000 rpm. Its all-metal construction requires no lubrication, withstands high temperatures (-50°C to +300°C), and supports long-term maintenance-free operation. Widely used in wind power generation, marine propulsion, high-speed compressors, and other heavy-duty applications, it is particularly suitable for industrial drive systems demanding high reliability and precision.
