China 1500kw Diesel Marine Engine with Gear Box

Our marine gearbox is produced according to the technology introduced from LOHMANN, Germany. It covers six series, among which, GWC, GWD, GWS and GWH series are ahead-astern clutch reduction gearboxes; GWL and GWK clutch reduction gearboxes. Their structural features are as follows:
GWC series: Have double-step reduction (primary and final) and reversal step input shaft and output shaft are homocentric arranged, with the rotation direction same SGW model of double ratios is a derivative of GWC series.
GWD series: Have single-step reduction (no primary) and reversal step one of the two clutch shafts functions as a driving shaft; Input and output shafts are angular heterocentric arranged, with the rotation direction contrary.
GWS series: No primary device, only have final and reversal step; Input and output shafts are vertical heterocentric arranged, with the rotation direction contrary.
GWH series: No primary reduction device, only have final and reversal steps; Input and output shafts are horizontal heterocentric arranged, with the rotation direction cintrary.
GWL series: Have no functions of ahead and astern; Similar to GWC series in construction, but only have primary and find reduction devices; Input and output shafts are homocentric arranged with the rotation direction same.
GWK series: Have no functions of ahead and astern; only have single-step reduction device; Input and output shafts are vertical heterocentric arranged with the rotation direction contrary.
