The purpose of this utility model is finished by following technical solution, and it mainly includes lower box, input block, drive disk assembly, output block; The input shaft that input block is arranged by bearing installation on the described upper box, an end of input shaft has the input driving gear by middle plain bearing sliding sleeve, between input driving gear and input drive gear first clutch is housed; Described input drive gear is meshed with hot jacket has clutch outer member on the transmission shaft of drive disk assembly transmission gear, the other end of transmission shaft also has transmission gear by middle plain bearing sliding sleeve, between transmission gear and the transmission gear second clutch is housed; Described input driving gear and transmission gear mesh with the driven gear of hot jacket on output shaft respectively.
Described input driving gear and transmission gear are connected with the transmission transmission gear with input drive gear respectively by first and second power-transfer clutchs separately, described first and second power-transfer clutchs are the hydraulic actuated multi-disc wet clutch, be respectively equipped with clutch plunger on it, one side of piston is communicated with fluid chamber, another side is provided with return spring, and output shaft links to each other with marine rear shaft by plunging joint.
The described axis centre face of going up the split surface of lower box by input and drive disk assembly, the mounting bracket that lower box and bears propeller thrust is connected as a single entity; On described box part, be fixed with oil pump by bonnet; Top at described upper box is furnished with control block hydraulic unit with, and this control block hydraulic unit with communicates respectively with described first and second power-transfer clutchs by built-in oil duct.
The utility model is with each function part integration of gear case, and modularization reduces excessive part, can satisfy the designing requirement of ship type better.It has the structural arrangement compactness, good looking appearance, and work and maintenance reliability height can adapt under high rotating speed characteristics such as long-term work.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a gear transmission section-drawing of the present utility model.
The specific embodiment
Below will the utility model is further introduced by accompanying drawing:
The utility model mainly comprises lower box 1, input block, drive disk assembly, output block etc.On upper box 1, be separately installed with input shaft 3 by bearing 2,4, one end sliding sleeve of input shaft has input driving gear 7, there is plain bearing 8 centre, passing tooth 6 in input is equipped with power-transfer clutch 17 described input drive gears 6 between the driving gear 7 and is meshed with hot jacket has clutch outer member on transmission shaft 10 transmission gear 9 with importing, transmission shaft 10 is installed on the casing 1 by bearing 28,29, the other end of transmission shaft also sliding sleeve has transmission gear 12, there is plain bearing 8 centre, between transmission gear 9 and the transmission master tooth 12 power-transfer clutch 18 is housed also.Described input driving gear 7 and transmission gear 12 mesh with the driven gear 14 of hot jacket on output shaft 15 respectively; Output shaft also is placed on the casing 1 by pair of bearings 11,13 and bearing 16.Input driving gear 7 and transmission gear 12 are connected with transmission transmission gear 9 with input drive gear 6 respectively by hydraulic actuated multi-disc wet clutch 17,18 separately, the one side that is respectively equipped with clutch plunger 19,20. pistons on the power-transfer clutch 17,18 is communicated with fluid chamber 26,27, and another side is provided with return spring 21,22. output shafts 15 and links to each other with marine rear shaft by plunging joint 23.
The utility model is in the body structure design, and the split surface of last lower box is by the axis centre face of input and drive disk assembly, as long as the gear case upper box lid is opened, input and two parts of transmission just can take out fully, keep in repair easily; Supporting way slided on input and the transmission shaft in driving gear adopted, and dynamical axis mainly bears twisting force, has strengthened transmission capacity, had reduced the number of bearings of support and the overall weight of gear case simultaneously; The mounting bracket and the lower box that bear propeller thrust are connected as a single entity, and make rigidity increase, the weight saving of gear case; Oil pump is fixed on the box part by bonnet; Control block hydraulic unit with is arranged in the top of upper box, and is identical with power-transfer clutch by built-in oil duct.
During use, when bar handle " stopping " position, promptly simultaneously the power fluid of the power-transfer clutch on input shaft 3 and the transmission shaft 10 17,18 is switched to back oil road, clutch plunger 19,20 breaks away from friction lining rapidly under the effect of return spring 21,22, input driving gear 7 and transmission gear 12 sky respectively are enclosed within on input shaft 3 and the transmission shaft 10, thereby, can not drive the driven gear 14 of hot jacket on output shaft 15 and rotate, screw propeller stops not change.
When bar handle in " ahead running " position, the work oil duct of the power-transfer clutch 17 of input shaft 3 with connect with oil pump, operating oil pressure promotes clutch plunger 19 pressing friction sheets, input driving gear 7 is rotated synchronously with input shaft 3, and drive driven gear 14 backward rotation, at this moment, boats and ships advance.
When bar handle " reversing " position, the work oil duct conducting of transmission shaft 10 power-transfer clutchs 18, operating oil pressure promotes clutch plunger 20 pressing friction sheets, transmission gear 12 and transmission shaft are rotated synchronously, and drive driven gear 14 backward rotation, at this moment, boats and ships retreat.
The utility model is placed in control block hydraulic unit with integral body on the upper box, connects the power-transfer clutch epitrochoidal chamber by interior oil circuit, possesses compact design layout more, good looking appearance; Other three cover parts all directly are supported on the casing by bearing, make precision higher, and safe and reliable.
