Key features of Advance GWK70.76 Marine Gearbox
GWK70.76 reduction gear has no reverse function and is of single stage design. Input and output are vertically offset and have opposite sense of rotation.
| Input Speed (rpm) | Ratio | Rate (kW/rpm) |
| 300-900 | 1.94 | 8.111 |
| 2.54 | ||
| 3.00 | ||
| 3.50 | ||
| 3.95 |
Important note:
The Advance marine gearbox GWK70.76 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.
