RENK Compact Planetary Gear CPG

Innovative Power Transmission


CPG – direct coupled planetary gearbox

Power range: 1 – 30 MW

Low speed: 1000-2500 rpm

High Speed: 5000-25000 rpm

Ratio: 5 - 12

Efficiency: 98,3 - 99,2%


CPG – advantages

The CPG concept offers:

• Short delivery time

• Both couplings included

• Both coupling guards included

• Typical no baseframe required

• No allignment on l.s.s.

• Electric Machine tested with gear mounted

• Coaxial arrangement

• More compact shaft trains (shorter)

• Reduced clarification required


CPG – Prinziple CPG112z/3L - ODK GT

Direct coupled to GT

Coupling and guard included.

Connection to generator:

Alternative 1

direct coupled (as shown)

requires a generator plate to

connect the gearbox housing

Alternative 2

Free standing gearbox (not

shown) with own bearing

support at low speed shaft

requires additional a coupling

and add. axial space,

Baseframe…!

Sample for 4800 KW / 10519/1000 rpm Efficiency 98,35% for Altern. 1


CPG – free standing arrangement

Solution applied for large machines with foot mounted bearings


CPG – Disassembly

The high speed coupling length is to be selected to

give propper axial space

CPG – Summarize

• Easy access and disassebly

• Integrated couplings and guards

• Minimized overhang to electrical machine

• Low weight compared with parallel shaft solutions (50%)

• No axial forces out of gearing system

• Compensation of termal movements of high speed shaft

• Equal load distribution without peak compared to helical

• Reduced power losses and oil requirements

• Low airborne sound level due to partial double wall casing.

• Coaxial design

• Reduced base frame costs
