EQ-Flex®

EQ-Flex provides the reliable transmission of the torque and ensures the torque limitation in the event of an overload. Sturdy materials ensure long service life in the most challenging environmental conditions.

The RAFLEX® portfolio offers the ideal solution for almost any application area due to our products from the standard and high-speed series. A torque limiter and an electrical insulation to protect other system components from leakage currents were developed for use in wind turbines in particular. Operators benefit from maintenance-free and the wear resistance as well as from a technical functional design appropriate to the system. The use of high-quality, certifiable materials ensures the sustainability of the system as well as the easy assembly, compact and simple design.

EQ-Flex steel disk coupling consist of optimized as well as maintenance-free and wear-free components. They are designed for a complete system lifetime, even in the most demanding environmental conditions. Due to the layered structure of the specially shaped disks, these couplings compensate axial, radial, and angular misalignments between the drive and driven machines without generating high restoring forces.

An innovative and patented torque limiter gives the coupling decisive advantages for enhancing the system  availability and optimizing the maintenance costs. An adjustment of the slip torque is now possible for the first time within a  few minutes without disassembling the coupling. Especially for the coaxial platform configuration, the use of RENK torque limiter simplifies the coupling adjustment and avoids the complex disassembly of the pitch wire.
