The GW series marine gearbox has small size. Its high torque transmission capacity,with a speed range form 360 to 1800 rpm and reduction ratio between 2:1 and 6:1,can vary within the range of 0.38 to 46.2. The value depends on size and reduction of the gearbox.
The marine gearbox is available in six types,including four reverse reduction gearboxes and two reduction gearboxes without reversing function(each type divided into eleven models).
According to the varied relative position of input and output shaft,the gearbox can be either coaxial or offset, the latter can be subdivided into gearboxes with vertically ,horizontally or diagonally offset shaft. The modular design affords a variety of advantages including low-cost manufacture and minimum spare parts.
