Background technology
The marine gear box of existing equal-wattage, as MA125 type ship gear case, its structure adopts three five gear transmission layouts, have suitable, clutch, deceleration, fall and arrange along two cover power-transfer clutchs rear end arranged side by side, this arrangement has increased the difficulty of mounting or dismounting, also causes dynamical axis will bear the bending application force simultaneously, thereby has reduced the transmission of power ability; All be supported on the casing with the intermeshing driving gear of output shaft driven gear two ends on input shaft and the transmission shaft with two ball-bearing casings; Hydraulic control device is that an independent parts bolt together is on the transmission bonnet of gear case; Shared 12 bearing arrangments of the input of gear case, transmission and three axles of output support.Said structure all causes difficulty to layout small-sized, light-duty marine gear box, has caused the volume of existing gear case bigger inevitably, Heavy Weight, and it is attractive in appearance that profile is owed, body structure complexity, shortcomings such as manufacturing cost height.Because the axle head excessively extension of output shaft has increased the external force that the cantilevered moment of flexure is produced to bearing axial capacity originally again with regard to weak deep groove ball bearing, make reduce greatly the service life of ball-bearing casing in addition.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of volume little, in light weight, structural arrangement compactness, good looking appearance, good reliability, the light high-speed marine gear box that precision is high.It is with input shaft, transmission shaft and output shaft respectively by bearing installation on casing, input shaft links to each other with power by coupler, one side hot jacket has input drive gear on the axle, another side is equipped with the input driving gear by bearing, between two gears input clutch is housed, power-transfer clutch has piston on one side, and piston links to each other with hydraulic control device by fluid chamber; Transmission transmission gear and transmission gear and middle drive clutch are installed on transmission shaft too; Transmission gear on input shaft and the transmission shaft is meshing with each other, driving gear on input shaft and the transmission shaft simultaneously with output shaft on the driven gear engagement, external coupler of output shaft and marine rear shaft, described hydraulic control device is arranged in the gear case rear end, and is connected as a single entity with rear side housing and power-transfer clutch oil-feed device.
Described input shaft rear side housing is provided with and enters the lubricated of power-transfer clutch and the oil duct and constitute power-transfer clutch oil-feed device of working, and hydraulic control device directly is arranged on the rear side housing, omits to connect link, makes compact conformation; And the buckle type oil sealing is adopted in rear end blowout patche power fluid oil-feed place of input shaft, makes sealing effectiveness better.
Be fixed with oil pump on the rear side housing of described transmission shaft, this oil pump links to each other with transmission shaft by adapter sleeve, and rear side housing is provided with conducting turnover oil duct with the oil pump faying face and communicates with oil sump and cooling vessel respectively, has increased reliability, makes profile more attractive in appearance.
Described input shaft, transmission shaft and output shaft all are supported on the casing by two tapered roller bearings, and two driving gears respectively slide over respectively on input shaft and the transmission shaft by plain bearing, have compressed arrangement space, improve transmission speed.
The utility model compared with prior art, it is little, in light weight to have a volume, the structural arrangement compactness, good looking appearance, characteristics such as good reliability, the working condition that it more can meet speedboat, yacht satisfies user's requirement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a transmission shaft structure scheme drawing of the present utility model.
Fig. 3 is a gear transmission generalized section of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: as shown in Figure 1, by a pair of tapered roller bearing 2,11 input shaft 3 is installed on casing 1, the one end links by importing axle sleeve and coupler 5 and power.The front end hot jacket of input shaft has input drive gear 6, one ends that have clutch outer member to be lined with plain bearing 8 sliding sleeves by the centre input driving gear 7 is arranged.Input drive gear 6 is meshed with the transmission gear that has clutch outer member 9 of hot jacket on transmission shaft, sees shown in the accompanying drawing 2.Transmission shaft 10 also is installed on the casing 1 by a pair of tapered roller bearing 2,11, the other end of transmission shaft 10 also sliding sleeve has transmission gear 12, also be lined with plain bearing 8 in the middle of it, input driving gear 7 and transmission gear 12 mesh with the driven gear 14 of hot jacket at output shaft 15 respectively.Output shaft also is installed on the casing 1 by a pair of tapered roller bearing 16.Input driving gear 7 and transmission gear 12 connect with input drive gear 6 and transmission transmission gear 9 respectively by hydraulic actuated Wet-type multi-disc friction clutch 17,18 separately, are respectively arranged with clutch plunger 19,20 on the power-transfer clutch 17,18.One side of piston is joining fluid chamber 26,27, and another side is provided with return spring 21,22.Output shaft 15 links to each other with tailing axle by plunging joint 23.The rear side housing of input shaft 3 is provided with and enters the lubricated of power-transfer clutch and the oil duct and constitute power-transfer clutch oil-feed device of working, and hydraulic control device 24 directly is arranged on the rear side housing, omits to connect link, makes compact conformation; And the buckle type oil sealing is adopted in rear end blowout patche power fluid oil-feed place of input shaft 3, makes sealing effectiveness better.
Be fixed with oil pump on the rear side housing 25 of described transmission shaft 10, this oil pump links to each other with transmission shaft by adapter sleeve, and rear side housing 25 is provided with conducting turnover oil duct with the oil pump faying face and communicates with oil sump and cooling vessel respectively, has increased reliability, makes profile more attractive in appearance.
During use, when bar handle " stopping " position, promptly simultaneously the work oil duct of the power-transfer clutch in input shaft 3 and the transmission 10 17,18 is switched to back oil road, clutch plunger 19,20 hightails friction lining 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, therefore they can not drive driven gear 14 rotations of hot jacket on output shaft 15, propeller stops not change, the interior oil of hydraulic efficiency gear this moment all is lubricating oil, by each oil duct each lubricating point to gear case.When bar handle in " ahead running " position, the work oil duct conducting of the power-transfer clutch 17 of input shaft 3, the work oil duct promotes clutch plunger 19 pressing friction sheets, input driving gear 7 is rotated synchronously with input shaft, and drive driven gear 14 backward rotation, at this moment, boats and ships advance.When bar handle in " reversing " position, the work oil duct conducting of the power-transfer clutch 18 of transmission shaft 10, operating oil pressure promotes clutch plunger 20 pressing friction sheets, transmission gear 12 and transmission shaft are rotated synchronously, and drive the driven gear backward rotation, at this moment, boats and ships retreat.
