Planetary gearboxes have been an important part of RENK’s product portfolio for many decades. RENK’s planetary 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.
Most cost-effective free-standing gearbox solution
Low space requirements
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
Power: 2 – 35 MW
Low speed shaft: < 3 600 rpm
High speed shaft: < 20 000 rpm
Ratio: 3 - 11
