Key features of Advance GWS66.75 Marine Gearbox
GWS66.75 reverse reduction gear has no primary stage, but a reduction and a reverse stage. Input and output are vertically offset and have opposite sense of rotation.
| Input Speed (rpm) | Ratio | Rate (kW/rpm) |
| 300-950 | 1.97 | 7.200 |
| 2.47 | ||
| 3.00 | ||
| 3.52 | ||
| 3.95 |
Important note:
The Advance marine gearbox GWS66.75 can not be held responsible for torsional problems arising from the drive system. We therefore recommend that a calculation and adjustment for the vibrational data of the ship’s entire drive system should be performed including the torsional compatibility of the gearbox.
