Fig. 1 is differential cross pin figure of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is differential control system device schematic diagram of the present utility model.
The specific embodiment
For example the utility model is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～3, this device is comprised of following three parts:
One, differential cross pin
Differential cross pin is comprised of following two parts
1, major-minor gear, planetary wheel.Connect the left-and-right spiral oar by semiaxis.Two planetary wheels of diff did not rotate when trimaran was kept straight on, and during ship turning, rotating speed is different as required for two planet teeth of diff and both sides semiaxis, realizes differential, causes the both sides propeller speed different, ship turning.
2, gear case.Come the gear transmission assembly of transmitted power by transmission gear, the moment of torsion of main frame is realized that with two cone gears vertical transmission is to the both sides semiaxis.
Two, be installed on the symmetrical expression twin screw of main body both sides
The propeller arrangement that is installed between the master hull mainly is comprised of three parts:
1, screw propeller.It adopts common three bladed propeller or quadruple, and the propeller blade rotation direction of the left and right sides is opposite, and propeller disk and other coefficient are all identical.Two screw propellers are installed on main body and position, side hull middle, and left-right symmetric is installed.
2, right angle gear transmission.The right-angle structure pattern is adopted in transmission between power generating apparatus and the screw propeller, is connected by gear case by bevel gear.
3, propeller arrangement is installed on the connecting bridge downside, is immersed in fully in the water, is lower than the floating line of trimaran.
Three, differential control system
Differential control system is comprised of following two parts
1, parameter acquisition CPU device.The live signals such as the speed of a ship or plane when the collection trimaran travels, course, and the expection signal of setting is done contrast, the deviation that calculating exists, the voltage signal of output adjustment amount.
2, electronic brake.Receive the voltage signal that the CPU device passes over, semiaxis is realized asymmetric braking, thereby change the rotating speed of semiaxis.
During vessel motion, marine main engine is passed to diff input shaft 9 with moment of torsion, and diff input shaft 9 drives initiative taper generating gear 2 and rotates.Initiative taper generating gear 2 is in the whole gear case of diff, driving gear ring 6 rotates, two small planetary gears 8 of diff that drive on it by diff framework 3 and compensating-gear shaft 7 when gear ring 6 rotates, diff small planetary gear 8 drive the side gear 4 simultaneously synchronized rotations of the left and right sides.The side gear 4 of both sides links to each other with semiaxis 5, in the 1 interior rotation of transmission shaft shell.When the trimaran turning, suitably brake a side semiaxis by electronic brake, diff small planetary gear 8 on the diff framework 3 is inconsistent with small planetary gear 8 rotating speeds of opposite side by connected compensating-gear shaft 7, thereby make the side gear 4 of both sides speed discrepancy occur, after jackshaft 5 drives another secondary cone gear change torque direction, control both sides prop shaft 12 rotates with friction speed, realizes the boats and ships break-in.
The power of main frame is through the transmission of diff, from passageway between main body 18 and the side hull 17 is passed in main body 18 inside.Jackshaft 5 is installed on the connecting bridge 15 in main body 18 outsides, by gear case 16 under the combined action of prop shaft bevel gear 10 and transmission shaft bevel gear 11, the rotation of transmission shaft 5 is passed to vertical prop shaft 12, prop shaft 12 drives common screw propeller 13 and rotates, thereby the promotion trimaran is turned or advanced.Prop shaft 12 is installed on main body and side hull midway location 14, left and right sides full symmetric.Being combined with of the installation site of screw propeller and differential cross pin, further improved the propulsion coefficient of trimaran engine installation, improved the fuel service efficiency of trimaran, reduced the resistance of propeller when trimaran advances, the vibration and the noise that have produced when having reduced the screw propeller operation.
The live signal 24 such as the speed of a ship or plane, heading sensor 22 gathered and processes when 20 couples of differential control system CPU navigated by water from trimaran, and with desired signal 26 contrasts from rotation angle sensor 23, calculate the error that exists, output needs the control voltage 25 of adjustment amount, control electronic brake 21, make electronic controller 21 change the rotating speed of diff jackshafts 9, the speed of regulating both sides screw propeller 13 reaches the purpose of turning.
The utility model patent is compared with marine powerplant installation form (for example being installed in the hull afterbody) of the same type: the efficient of the utility model patent will be higher by 2%～3% than the efficient of common engine installation installation site; The device of this patent institute utility model substitutes the rudder for ship of boats and ships with symmetrical propeller arrangement.General boats and ships all have rudder for ship now, are used for changing the direction of ship's navigation.Common rudder for ship has the two large functions that keep the boats and ships predetermined course and change direction of ship travel.In the place that power machine drive mechanism and power generating apparatus (diesel engine, automotive gas turbine, steam turbine, nuclear power plant etc.) should be installed originally, install battery pack.Adopt differential cross pin to control symmetrical screw propeller, when vessel motion, the differential controls system gathers and contrasts every operational factor of trimaran, and the velocity contrast of regulating two screw propellers by diff reaches the purpose that turns to.
