It closes, II grade of gear wheel connects output shaft；The coaxially connected reverse-gear of I grade of pinion gear, the output end dress of reverse-gear
There is reversing friction clutch, the output end of I grade of canine tooth is equipped with positive vehicle friction clutch.
One kind high-power ahead and astern gear assembly peculiar to vessel of the invention realizes that power carries shunting using torsion shaft,
Using just, reversing friction clutch as ahead and astern change working component, positive vehicle friction clutch is located at I grade of canine tooth end,
Vehicle friction clutch is located at II grade of pinion gear end.With realize high-power naval vessel just, reverse-gear drive mechanism, switch speed is fast
And the stable effect of switching.
Detailed description of the invention:
Fig. 1 is schematic structural view of the invention.
Specific embodiment:
As shown in Figure 1, one kind high-power ahead and astern gear assembly peculiar to vessel of the invention, is big by transmission mechanism 11 and II grade
Gear 4 is constituted, and two transmission mechanisms 11 are meshed with II grade of gear wheel 4, and the transmission mechanism is by I grade 1, I grade of pinion gear
2, II grades of pinion gears 3 of canine tooth, reverse-gear 5, torsion shaft 7, positive vehicle friction clutch 8, reversing friction clutch 9 and gas turbine
Output shaft 10 is constituted, I grade of 1 axis connection of pinion gear on gas turbine output shaft 10, I grade of pinion gear 1 with two I grade greatly
Tooth 2 is meshed, and I grade of canine tooth 2 is coaxially connected by torsion shaft 7 with II grade of pinion gear 3, is located inside on two transmission mechanisms 11
II grade of pinion gear 3 is meshed with II grade of gear wheel 4, and II grade of gear wheel 4 connects output shaft 12；I grade of pinion gear 1 is coaxial
It is connected to reverse-gear 5, the output end of reverse-gear 5 is equipped with reversing friction clutch 9, the output end dress of I grade of canine tooth 2
There is positive vehicle friction clutch 8.Axis connection is all made of diaphragm coupling 6 in device.
One kind high-power ahead and astern gear assembly peculiar to vessel of the invention, it is each to ensure using branched power technology
Branch power distribution is uniform, accomplishes that each branch all transmits the power of host 50% as far as possible, to guarantee load property, in I grade of 2 He of canine tooth
7 are realized using torsion shaft between the grade of II grade of pinion gear 3.Positive vehicle friction clutch is located at I grade of 2 end of canine tooth, friction clutch of moving backward
Device is located at II grade of 3 end of pinion gear.Just, reversing friction clutch control valve group control strategy should be interlocked relationship, just, move backward
Maximum torque that friction clutch can transmit and it is non-slip, while can also in longer period of time (about 10S) interior energy
Overcome the torque of propeller, in this course, just, reversing friction clutch can consume the energy of skidding.Due to combustion gas
Turbine input speed is constant, realizes the change that II grade of gear wheel 4 turns to by gear wheel-train and friction clutch 8.
Branched power technology is used in double combustion engine and vehicle operational process, can use transmitting needed for one-stage gear adjutant
Power dividing is two, and each branch only transmits the half of lotus published originally, then by connection between torsion shaft and grade to pass to second level small
Gear.This load for bearing meshing gear substantially reduces, and the size of gear pairs and retarder at different levels is reduced.
Realize that the matching of double combustion engine and vehicle load property is applied on level-one pinion shaft after combustion engine starting by torsion shaft
Torque gradually increase.During the loading process, the level-one gear wheel of two branched structure Zhong Hui Xian Youyige branches and level-one are small
Gear enters engagement, and the inside and outside tooth of spline that the second level pinion gear of the branch couples between second level gear wheel and grade is also same
When enter meshing state.At this moment, due to the influence of manufacturing and fixing error, one-stage gear in another branch is secondary, second level
Gear pair and spline pair are not introduced into meshing state or have one or two link not enter into meshing state --- flank
There are gaps.With the increasing of input torque, the flexible deformation of the torsion shaft of the branch by being introduced into meshing state is eliminated
The backlash of another branch makes all gears of two branches and spline all enter meshing state.
Its operational mode are as follows: in combustion engine starting, host by I grade small tooth 1 by power-sharing to two I grade of canine tooths 2,
Power is transmitted to respectively in II grade of pinion gear 3 by torsion shaft 7, power is merged in II grade of canine tooth by two II grade of pinion gears 3
On wheel 4, and it is transmitted to stern tube shaft spacing paddle, pushes naval vessel operation.
When needing naval vessel to go to backward running operating condition from ahead operation operating condition, positive vehicle friction clutch 8 is disconnected first,
I grade of canine tooth 2 at this time, II grade of pinion gear 3, II grade of gear wheel 4 run out of steam source, follow stern tube shaft to carry out inertial rotation, start at this time
Reversing friction clutch 9, host combination reverse-gear 5 are realized by reverse-gear 5 by power transfer to II grade of gear wheel 4
Naval vessel reversing.
When needing naval vessel to switch to ahead operation operating condition from backward running operating condition, reverse-gear 5 is disconnected first, is fallen at this time
Skiving wheel 5 and II grade of gear wheel 4 run out of steam source, and stern tube shaft is followed to carry out inertial rotation, combine positive vehicle friction clutch 8 at this time,
Host combines I grade of canine tooth 2, and II grade of pinion gear 3 drives II grade of gear wheel 4 to realize host ahead operation.
