Embodiment
Below will the utility model is further introduced by accompanying drawing: shown in the accompanying drawing 1,2, the utility model mainly is made up of casing, input shaft parts, transmission shaft parts and output shaft assembly, is respectively arranged with clutch 1,11 near power intake on the transmission shaft of the input shaft of described input shaft parts and transmission shaft parts; The front end hot jacket of described input shaft 2 has the input drive gear 3 that has clutch outer member, the rear end is set with input driving gear 4, input drive gear 3 and hot jacket driving gear 9 on transmission shaft 8, that have a clutch outer member equally is meshed, the rear end of transmission shaft 8 also is set with transmission gear 12, input driving gear 4 and transmission gear 12 mesh with output driven gear 15 simultaneously, the output shaft 16 of output driven gear 15 hot jackets on output shaft assembly, output shaft 16 pass through with it, and the coupling 17 of one links to each other with tailing axle.
Shown in the accompanying drawing 2, two bearings are passed through on casing in described input shaft 2 two ends; Transmission shaft 8 also be by two Bearing Installation on casing; Two self-aligning thrust roller bearings of output shaft 16 usefulness and a roller bearing are supported on the casing.
For guaranteeing the maintenance and the mounting or dismounting of gear-box, casing of the present invention is divided into upper, middle, and lower part, upper box 18 and middle casing 19 are along transmission shaft 8 line of centres horizonally splits, middle casing 19 and lower box 20 are along input and output shaft 16 line of centres horizonally splits, and input shaft 2 is connected with coupling 5, output shaft 16 and the easily detachable connecting structure of output driven gear 15 tapering interference.Output shaft coupling and output shaft are to be one.
Shown in Figure 2, on the casing that middle casing 19, lower box 20 constitute, input shaft 2 is installed by a pair of roller bearing, input shaft 2 front ends link with power by coupling 5 and high-elastic coupling 14, front end hot jacket on the axle has the input drive gear 3 that has clutch outer member, and the rear end is set with input driving gear 4.Input drive gear 3 is meshed with the transmission driving gear 9 that has clutch outer member of hot jacket on transmission shaft, and on casing 18,19, the rear end of transmission shaft 8 also is set with transmission gear 12 to transmission shaft 8 by two Bearing Installation.Input driving gear 4 and transmission gear 12 mesh with output driven gear 15 simultaneously, the output shaft 16 of driven gear 15 hot jackets on output shaft assembly, output shaft 16 have on two self-aligning thrust roller bearings and two the roller bearing supporting box 19,20.Output shaft 16 passes through with it, and the shaft coupling 17 of one links to each other with tailing axle.Described input clutch 1 is arranged in the input drive gear 3, Yi Bian clutch 1 has piston 7, piston links to each other with hydraulic control system 13 by hydraulic fluid chamber; During use, when Joystick " stopping " position, promptly simultaneously the work oil duct of the clutch on input shaft 2 and the transmission shaft 81,11 is switched to back oil road, clutch plunger 7,10 is thrown off friction plate rapidly under the effect of return spring, input driving gear 4 and transmission gear 12 sky respectively are enclosed within on input shaft 2 and the transmission shaft 8, thereby, can not drive the driven gear 15 of hot jacket on output shaft 16 and rotate, thereby propeller stops not change.At this moment, the oil in the hydraulic system all is lubricant oil, by each oil duct each lubricating point to gear-box.When Joystick " ahead running " position, the work oil duct conducting of the clutch 1 of input shaft 2, operating oil pressure promotes clutch plunger 7 pressing friction sheets, input driving gear 4 is rotated synchronously with input shaft, and drive output driven gear 15 backward rotation, rotate thereby drive output shaft and propeller, at this moment, boats and ships advance.When Joystick " reversing " position, the work oil duct conducting of the clutch 11 of transmission shaft 8, operating oil pressure promotes clutch plunger 10 pressing friction sheets, transmission gear 12 and transmission shaft are rotated synchronously, and drive output driven gear 15 backward rotation, rotate thereby drive output shaft and propeller, at this moment, boats and ships retreat.
Boats and ships berth or by in being towed, and traction pump lubrication system drives pump housing work by traction pump driving gear 22 engagements on the traction pump drive gear on the traction pump drive shaft 24 23 and the output shaft.Scavenger valve is opened (automatically) during ship running, and the lubricant oil that the traction pump extracts directly flows back to the gear-box oil sump.
The specified input transmission capacity of the utility model gear-box is 1.204kw/r.min
-1(being that moment of torsion is 11498N.m) is middle high power gearbox, is used for the cargo ship about 5000 tons.
