GC Series Marine Gearbox(matched with controllable pitch propeller)

There are five series in GC Marine Gearbox(matched with controllable pitch propeller), among which GCS is the fundamental one:
GCS Series: this series has one reduction stage, and can apply the function of reduction. Its input and output is vertically offset and
of opposite rotation directions. An oil distributor can be fixed at the output front end for CPP and a PTO can be fixed vertically above
the output.
GCST Series: this series has one reduction stage, and can apply the function of reduction. Its input and output is vertically offset
and of opposite rotation directions. An oil distributor can be fixed at the output front end for CPP and a PTO and a PTI can be fixed
vertically above the output.
GCD Series: this series has one reduction stage, and can apply the function of reduction. Its input and output is angularly offset and
of opposite rotation directions.An oil distributor can be fixed at the output front end for CPP and a PTO can be fixed angularly above
the output.
GCH Series: this series has one reduction stage, and can apply the function of reduction. Its input and output is horizontally offset
and of opposite rotation directions. An oil distributor can be fixed at the output front end for CPP and a PTO can be fixed at the
horinzontally opposite side of the output.
GCCSeries: this series has two stages for reduction, and can apply the function of reduction. Its input and output is coaxial and of
the same rotation direction. A PTO can be fixedat the horizontally opposite side of the output.
Control Mode:Pneumatical or electrical operation

GW series marine gearbox covers six series, among which G W C, G W D, G

GW SERIES
W S and G W H series are ahead-astern clutch reduction gearboxes, and G
W Land G W K clutch are reduction gearboxes.
Structural features:
G W C series: Double-step reduction (primary and final) and reversal step. Input
and output shafts are homocentric with same rotation direction. G W S model of
double ratio is a derivative of G W C series.
G W D series: 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
hetero-centric arranged with the rotation direction contrary.

G W S series: No primary device, only final and reversal steps; Input and output shafts are vertical hetero-centric
with contrary rotation direction.
G W H series: No primary reduction device, only have final and reversal steps; Input and output shafts are horizontal

hetero-centric with contrary rotation direction.
G W L series: No function of ahead and astern; Similar to G W C series in construction, but only have primary and
find reduction devices; Input and output shafts are homocentric with same rotation direction.
G W K series: No function of ahead and astern; Only single-step reduction device; Input & output shafts are
vertical hetero-centric with contrary rotation direction.

HIGHLY-FLEXIBLE COUPLING

HGT series highly flexible couplings

occupy 50% shipbuilding market in China, similar to the world
famous “VULKAN”RATO couplings.The highly flexible
HGT coupling is a torsionally flexible rubber coupling which
can compensate radial, axial and angular shaft displacements
of the connected machinery. T h e t or q u e is transmitted by
elements loaded in shear. The different torsional stiffness and
damping factors provide the possibility to satisfactorily tune the
torsional vibration behavior of the drive system. The essential
parts of the coupling are: the torsionally flexible part, the membrane
part and the connecting part. The torsionally flexible part consists

HIGHLY-FLEXIBLE COUPLING
of rubber elements, which can be arranged in one or two rows res-
pectively, depending on the coupling size and the stiffness level.
The flexible elements are divided into several segments. Due to
the element segments and in the case of multi-row couplings, a
displaced arrangement of the segments gives good ventilation
and cooling of the elements. The HGT couplings can be used
in ship's main propulsion, generator sets, pumps, fans and
compressors, especially when the internal combustion engine as the prime mover. It is unnecessary to remove the engine
or gearbox for the coupling mounting or replacing of the flexible elements.
As to the selection of specific type we use the formula:Tkn30≥K*9.55*P/n, where P is the rated power in kW, n is the
rated rotational speed in rpm, and K is the safety factor. We recommend K=1.5 for ship's main propulsion, K=1.3 for
generator sets and K=2.0 for mud pump.
The following is the specification of the two-row couplings. A typical expression of HGT5020 Ⅲ D is HGT－companycode,
50－rated torque 50kNm, 2－two rows of flexible elements, 0－stiffness code,Ⅲ－connecting mode by flange, and D－with
the overload device.
