Background technique
Existing common marine gearbox, primarily of casing, input block, the composition such as intermediate shaft part and output block, the gear-box of this structure can configure clutch according to actual needs, and input shaft and output shaft are arranged in parallel on casing, realizes horizontal power transmission; Therefore, existing marine gearbox cannot realize the transmission of power of existing inclination angle type (8 °) substantially.And inclination angle type ship powerplant module is needed for some boats and ships such as speedboat, fisheries administration ship, therefore prior art can not meet these special boats and ships to the actual demand of inclination angle type ship powerplant module.
Model utility content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of reasonable structural arrangement, compact, and beautiful shape, good reliability, precision is high, can meet the marine gearbox of inclination angle type ship powerplant module requirement.
The purpose of this utility model has been come by following technical solution, described marine gearbox, it is primarily of casing, input block, transmission shaft parts, output block forms, and input shaft one end of described input block is connected by input coupling and coupling and power, and on input shaft, on input end side, hot jacket has the input shaft driving gear of clutch outer member; On the transmission shaft that same and input shaft is arranged in parallel, on input end side, hot jacket has the transmission shaft driven gear of clutch outer member, and input shaft driving gear is meshed with transmission shaft driven gear;
The other end of described input shaft and transmission shaft is supported with input drive bevel gear and transmission drive bevel gear respectively by respective bearing, and described input drive bevel gear and transmission drive bevel gear by respective hydraulic operation wet-type multi-chip friction clutch respectively with input shaft driving gear and transmission shaft driven gear couplings;
Described input drive bevel gear and transmission drive bevel gear engage with the driven wheel of differential be placed on output shaft respectively, and input shaft and output shaft are formed with 6-10 ° of inclination angle.
Casing described in the utility model tiltedly cuts open structure by upper box and lower box employing and forms, and described upper box is separately installed with input shaft and transmission shaft by selfaligning roller bearing and roller bearing; The front end of described output shaft is arranged on lower box by the roller bearing of two tapered roller bearings installed face-to-face and rear end, and output shaft is connected with tailing axle by exporting shaft coupling; The other end of described input shaft is connected with the oil pump be fixed on by bonnet on casing.
For ease of assembling and maintenance, described upper lower box adopts and tiltedly cuts open structure, oil pump is fixed on box part by bonnet, driving gear and clutch outer member are designed to overall also hot jacket in the front end (by input side) of axle, therefore no matter suitable, reversing, less moment of flexure is only born at the thinnest position of axle, increases transmission capacity; Output shaft described in the utility model and input shaft inclination angle the best are 8 °, and it makes it reach maximum transmission capacity and reduction speed ratio meeting under reliability prerequisite; It is applicable to inclination angle type ship powerplant module, is particularly useful for the boats and ships such as speedboat, fisheries administration ship.
The utility model has reasonable structural arrangement, compact, and beautiful shape, good reliability, precision is high, can meet the features such as inclination angle type ship powerplant module requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is gear transmission sectional drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further introduced: shown in Fig. 1,2, marine gearbox described in the utility model, it is primarily of casing, input block, transmission shaft parts, output block forms, and input shaft 4 one end of described input block is connected by input coupling 18 and coupling and power, and on input shaft 4, on input end side, hot jacket has the input shaft driving gear 5 of clutch outer member; On the transmission shaft 7 that same and input shaft 4 is arranged in parallel, on input end side, hot jacket has the transmission shaft driven gear 6 of clutch outer member, and input shaft driving gear 5 is meshed with transmission shaft driven gear 6;
The other end of described input shaft 4 and transmission shaft 7 is supported with input drive bevel gear 11 and transmission drive bevel gear 19 respectively by respective bearing, and described input drive bevel gear 11 and transmission drive bevel gear 19 are connected with input shaft driving gear 5 and transmission shaft driven gear 6 respectively by respective hydraulic operation wet-type multi-chip friction clutch 8,9;
Described input drive bevel gear 11 and transmission drive bevel gear 19 engage with the driven wheel of differential 13 be placed on output shaft 12 respectively, and input shaft 4 and output shaft 12 are formed with 6-10 ° of inclination angle, and the best is 8 °.
Shown in figure, casing described in the utility model is adopted by upper box 1 and lower box 10 and tiltedly cuts open structure and form, and described upper box 1 is separately installed with input shaft 4 and transmission shaft 7 by selfaligning roller bearing 2 and roller bearing 3; The front end of described output shaft 12 is arranged on lower box 10 by the roller bearing 16 of two tapered roller bearings 14,15 installed face-to-face and rear end, and output shaft 12 is connected with tailing axle by exporting shaft coupling 17; The other end of described input shaft 4 is connected with the oil pump 20 be fixed on by bonnet on casing.
During use, when Joystick is in " stopping " position, hydraulic control system is by the ahead running clutch 8 on input shaft 4 and transmission shaft 7, the working oil of reverse clutch 9 directly connects back oil road, friction plate departs from, and input driving gear 11 and transmission gear 19 distinguish empty set on input shaft 4 and transmission shaft 7, thus, the driven gear 13 of hot jacket on output shaft 12 can not be driven to rotate, and propeller cavitation stops not turning.
When Joystick is in " ahead running " position, the working oil of ahead running clutch 8 oil cylinder on input shaft 4 imports, and promotes piston and pressing friction sheet, makes input driving gear 11 and input shaft 4 synchronous axial system, and drives driven gear 13 to rotate backward, and now, boats and ships advance.
When Joystick " reversing " position, the work oil duct conducting of the reverse clutch 9 on reverse shaft 7, friction plate compresses, and makes transmission gear 19 and reverse shaft 7 synchronous axial system, and drives driven gear 13 to rotate backward, and now, boats and ships retreat.
The utility model compared with prior art, has structural configuration compact, beautiful shape, the feature of good reliability.More meet working boat operating mode, meet user's requirement.
