1. 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.
2. 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.
3. 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.
4. The weight of the gearbox is approximation, for different reduction ratio the weight is different.
5. Due to the technical improvement of the products, the products may change without notice. For any other questions please contact our sales engineer.
