Advantages Of Advance GWC78.96 Marine Gearbox

Novel gearbox structure ensures reliable operation. The optimized design enables softer and smoother layout matching between the gearbox and engine.It is compatible with domestic and foreign high-speed diesel engines, and supports vertical, horizontal and inclined installation layouts to meet users’ various arrangement requirements.
The gearbox adopts a combined modular design. All moving components are elaborately designed and precision-machined to stringent standards, helping reduce fuel consumption and deliver stable running performance. It can be matched with most mainstream engine models.
Adopting 2-stage reduction design, the input and output share the same centerline. It is equipped with a reverse clutch reduction function under same-direction rotation conditions.
We provide professional technical support and after-sales service by gearbox specialists, with genuine spare parts readily available from stock.

The Marine gearbox has the function of reverse, clutch, deceleration and the thrust of the propeller, which is equipped with the main engine to form the Marine power unit.
The “transfer capacity” refers to the ratio of the engine’s rated power to the rated speed, and the reduction ratio corresponds to the transmission capacity, which should be less than the number be offered.
The gearbox and engine shafting are not allowed to use rigid connection, and the bracket is recommended to be installed on the same rigid support.If the engine is mounted on the elastic support, and the gearbox is installed on the rigid support, please contact the technical department of the company to select the suitable high elastic coupling.
The weight of the gearbox is approximation, for different reduction ratio the weight is different.
Due to the technical improvement of the products, the products may change without notice. For any other questions please contact our sales engineer.
