Marine gearbox (GW3941-4245)

GW reversing clutch gearbox used in driving units for vessels.

Their high torque transmission capacity covers a speed range from 360 to 1800 rpm depending on size and reduction and a torque power speed(N/n1) capacity from 0.38 up to 46.2 for reduction from 2 up to 6: 1.

The design family has six different modesl, four reverse reduction gears and two reduction gears without reversing function-each divided into eleven size. The relative configuration of input and output shaft is eighter coaxial or offset, the latter eigher vertically, horizontally or diagonally. The modular design affords a variety of advantages including low-cost-manufacture and spare stocking.
