Planetary gearbox COPAZ

precisionhigh-speedturbine

gearboxes transmit outputs of more than 20 MW and torques of more than 4.5 million Nm. Due to their optimized designs combined with high manufacturing quality, they prove particularly effective during long-term operation and thereby ensure the availability of the system over extended periods of time. RENK very successfully employs three-dimensional, corrected straight/high toothing in the COPAZ. The sun pinions and planetary carriers are case-hardened and ground, the ring gear is highly tempered, optionally hardened, and precision ground. The gearbox is free-standing; the high-speed coupling is included in the delivery. The uncomplicated construction of the COPAZ, its high production quality, and outstanding efficiency ensure low life cycle costs. The gearbox is used preferentially in turbine systems for power production purposes as well as in process technology. Features Most cost-effective free-standing gearbox solution Low space requirements Lightweight Integrated HSS couplings and coupling guards No internal axial forces caused by the system Compensation for thermal external axial forces possible Co-axial shaft arrangement (no center distance) Reduced noise emissions due to double-walled housing High degree of efficiency
