With the “EQ-Gear” and the “EQ-Flex” couplings, Renk is presenting two new products for wind turbines. The plain bearing technology of the gearbox enables an enormous power density through ideal load distribution. Special materials and innovative coating processes ensure optimum operation.
The intelligent planetary bearing ensures almost even load distribution in all operating conditions. The small variety of parts of the planetary gearconcept guarantees high reliability. The ability to master extreme forces makes the low-wear plain bearings a sustainable alternative to the usual ones Bearings. There is no lifetime restriction. At the same time, the modular design enables economical solutions for practically every application.
Engine and gearbox design energy-efficient and free of charge
The EQ-Gear is suitable for low and medium-speed platform configurations in a coaxial design and for the high-speed drive train with off-axis generator connection. Especially with the coaxial platform configuration, the cables required for pitch control can simply be routed through the gearbox between the input and output shafts. The wireless temperature monitoring ensures remote monitoring of plain bearings. The optimal load distribution between the planetary stages is self-adjusting. The entire drive train, consisting of the gearbox EQ-Gear, the clutch EQ-Flex with integrated torque measuring system and the Condition monitoring System VIB Monitor, can optionally be tested and validated on the in-house test bench. The gearboxes are certified according to IEC and GL guidelines.
Couplings, brakes and monitoring for the wind turbine
The torque limiter of the EQ-Flex coupling guarantees torque limitation in the event of overload. This increases the availability of the system and the operators benefit from the freedom from maintenance and wear resistance. The patented slip system ensures a variable and stable slip torque during operation. The slipping torque can be readjusted without having to dismantle the clutch in the drive train or do a new one Calibration possible in the test bench. The layer structure of the specially shaped lamellas compensates for axial, radial and angular misalignments between the drive and working machines without generating large restoring forces. The torque measurement takes place continuously.
