Planetary gearboxes
CPG - compact planetary gearboxes
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.
COPAZ – free-standing, compact planetary gearbox
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 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.
Planetary gearbox, P type
The planetary gearboxes of the P type are designed and constructed according to the latest findings and methods of gear unit technology.
The sun pinions of the single- or multi-stage planetary gearboxes rotate at up to 36,000 rpm. The gearbox housing and the customer’s connecting dimensions can either conform to RENK’s standards or be adapted completely to the requirements of the customer.
