Abstract
A gear case for ship includes a case body, input shaft components, transmission shaft components and output shaft components. Wherein, both the input shaft and the transmission shaft are arranged on the case body by bearings, a transmission gear with clutch shell is shrinkage-fitted at the front end of the two shafts respectively, a driving gear is arranged at the right side of the transmission gear, a bimetallic sliding bearings are fixed and sleeved into the inner hole of the two driving gears and stand on the shafts, the two clutches are respectively arranged inside the transmission gears of the input shaft and the transmission shaft. The utility model has the advantage of smaller bulk, lighter weight, more compact structure and arrangement, more reliable work compared with the prior art, and is applicable for ship with high requirement to gear case, such as a high-speed passenger ship, a workboat, and a yacht etc.
Description
Technical field
The utility model relates to the power drive of a kind of, clutch suitable by having of fluid control, deceleration, all kinds of boats and ships that are mainly used in high-speed ship, yacht and have above-mentioned functions belong to the driving device of ship power moving system.
Background technology
In the prior art, the structure of marine gear box of the same type mainly includes casing, input shaft parts, transmission shaft parts and output shaft assembly etc., in input shaft parts and the transmission shaft parts, the driving gear of kink on axle all adopt external support, the messenger chain complexity, part is many, cause the single-piece volume big, Heavy Weight is difficult to adapt to the supporting operating needs of high-speed ship.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of volume littler than existing product, weight is lighter, the structural arrangement compactness, the marine gear box of reliable operation, it includes casing, the input shaft parts, transmission shaft parts and output shaft assembly, wherein input shaft in input shaft parts and the transmission shaft parts and transmission shaft all by bearing installation on casing, each hot jacket of the front end of diaxon has the transmission gear of band clutch outer member, in its right side arranged adjacent driving gear is arranged, the endoporus of two driving gears is installed with bimetal sliding bearing and is bearing on the axle, and two power-transfer clutchs respectively are arranged in the transmission gear on input shaft and the transmission shaft.
Driving gear on described input shaft and the transmission shaft respectively with output shaft assembly in output gear engagement, this output gear connects with output shaft by tapering interference and key, one side of output shaft is equipped with a pair of tapered roller bearing, and opposite side is equipped with a cylindrical roller bearing and is bearing on the casing.
Described casing is divided into two parts up and down, and adopts and laterally tiltedly cut open connection structure.
The utility model compared with prior art, it is littler to have a volume, characteristics such as weight is lighter, and structural arrangement is compacter, and it is more reliable to work are applicable to that high speed passenger craft, repair ship, yacht etc. are to the demanding boats and ships of gear case.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a drive disk assembly structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: the utility model mainly includes casing 1, input shaft parts, transmission shaft parts and output shaft assembly etc.On casing 1, input shaft 2, transmission shaft 3 and output shaft 4 are arranged by bearing installation, the front end of input shaft links by input coupling and elastic coupling and power, the front end hot jacket of axle has the input drive gear 5 of band clutch outer member, in its right side arranged adjacent input driving gear 6 is arranged, the endoporus of this input driving gear is installed with bimetal sliding bearing 7 and is bearing on the axle, and input clutch 8 is disposed in the input drive gear 5.The structure of transmission shaft parts and input shaft parts are basic identical, it also has hot jacket transmission transmission gear 9 on axle, the band clutch outer member, on its right side also arranged adjacent transmission gear 10 is arranged, the endoporus of this transmission gear 10 is installed with bimetal sliding bearing 11 and is bearing on the axle, and a drive clutch 12 is disposed in the transmission transmission gear 9.Driving gear 6,10 on described input shaft 2 and the transmission shaft 3 respectively with output shaft assembly in output gear 13 engagement, this output gear 13 connects with output shaft 14 by tapering interference and key, one side of output shaft 14 is equipped with a pair of tapered roller bearing 15, and opposite side is equipped with a cylindrical roller bearing 16 and is bearing on the casing 1.Output shaft 14 links to each other outputting power by plunging joint 17 with marine rear shaft.The utility model is divided into two parts up and down with casing, and adopts and laterally tiltedly cut open connection structure, so that assembling and maintenance.
During work, when control setup in " stopping " when position, the clutch oil cylinder oil input channel on input shaft 2 and the transmission shaft 3 is connected oil sump, is in depressurization phase, piston in it is under the effect of return spring, break away from friction lining, input shaft and transmission shaft idle running, and the empty driving gear that overlaps on it does not change, meshing output gear respectively with two driving gears does not change yet, this moment, power was not exported, and the oil in the hydraulic control system all is lubricating oil, was sent to each lubricating point in the gear case by each oil duct.When control setup in " suitable " when position, the power-transfer clutch work oil duct conducting of input shaft, enter clutch oil cylinder, oil pressure promotes piston and overcomes spring force pressure friction-tight sheet, input driving gear and input shaft rotate synchronously, the output gear contrarotation that drive is engaged with drives output shaft and rotates, and this moment, boats and ships advanced.When control setup in " falling " when position, the power-transfer clutch on the input shaft is in depressurization phase, the clutch engagement on the transmission shaft, the transmission gear running, output gear that is engaged with and the rotation of input homophase, this moment, boats and ships fell back.
Claims (3)
1, a kind of marine gear box, it includes casing, the input shaft parts, transmission shaft parts and output shaft assembly, wherein input shaft in input shaft parts and the transmission shaft parts and transmission shaft all by bearing installation on casing, each hot jacket of front end that it is characterized in that described input shaft (2) and transmission shaft (3) has the transmission gear (5 of being with clutch outer member, 9), in its right side arranged adjacent driving gear (6 is arranged, 10), the endoporus of two driving gears is installed with bimetal sliding bearing (7,11) and be bearing in separately axle (2,3) on, two power-transfer clutchs (8,12) respectively be arranged in transmission gear (5 on input shaft (2) and the transmission shaft (3), 9) in.
