The coupling of doubly-fed unit is usually diaphragm coupling and some of them are connecting rod type and diaphragm type. The mainly composed of brake disk, diaphragm, locking assemblies, glass fiber tube and torque limiter.
Features:Tengxuan Technology
Strong fault tolerance and able to absorb large axial, radial and angular misalignment.
Have excellent electrical insulation, generally ＞100MΩ， it can be effectively reduce the electrical corrosion of gear box.
Strong ability to withstand short-term impact of large loads, the built-in torque limiter can reduce the short impact of high torque through silpping.
Light weight, suitable for high-speed applications.
