Abstract
The utility model relates to a reinforced gearbox for a ship, which belongs to the manufacturing technical field of a ship drive device. The utility model comprises a gearbox body, an input shaft, an output shaft, a drive shaft, a gearwheel fixedly connected to a shaft, an oil pump, a clutch, etc. The utility model is characterized in that the oil pump is arranged at the outer part, the drive shaft of the oil pump and the input shaft are in mesh, the output end of the drive shaft of the oil pump is arranged on the inner side of the gearbox body, and the shaft end extends the gearbox body. Through the connection of an open slot of the shaft end and a rotation shaft of the oil pump, the number of pinch surfaces of a friction disk in the clutch is increased from 10 to 12, and inner 6 pieces and outer 7 pieces are adopted. The utility model causes the replacement and repair of the oil pump to be very convenient, and at the same time, after the pinch surfaces of the friction disk of the clutch are increased to 12 pinch surfaces, the conveyance torsional force of the output shaft is increased by above 15 %.
Description
Technical field
The utility model belongs to marine transmission manufacturing technology field, the particularly a kind of and supporting middle low power reinforced marine gearbox of diesel engine for boats.
Background technology
Marine gear box be a kind ofly have down, suitable, clutch, deceleration, and can bear the marine gearing that propeller promotes.The common rotating speed of middle low power diesel engine for boats is higher, but can not reverse, and therefore, must match with marine gear box, and this could form unit power plant peculiar to vessel.So far, the commercially available marine gear box of China has formed different types of machines, is one of main frame type in the middle low power tooth case peculiar to vessel such as 135A type ship gear case.This type is located at oil pump in the case because of being subjected to the body structure space constraint, adopts nonstandard mark oil pump usually, and the outputting power of oil pump can not be regulated, in case when the horsepower output of gear case increases, can make high and low pressure oil circuit fuel feeding deficiency cause fuel tank to generate heat.Simultaneously, oil pump is the easily worn part of gear case, often needs to change.But built-in because of oil pump, changing needs to open the whole box body protecgulum, dismantles whole messenger chain, wastes time and energy, and influence is operation normally.Therefore, design a kind of fuel feeding abundance that can guarantee to guarantee when defeated turnout increases, reinforced marine gearbox that again can the easy disassembly oil pump is the problem that the insider explored always.
Summary of the invention
The utility model is at the above-mentioned defective of 135 type ships with gear case, do not changing former type size, under the prerequisite of spatial volume, the layout and the clutch facing of oil pump made improvements, design a kind of 135A reinforced marine gearbox that higher output power is arranged again rational in infrastructure.
The utility model solves above-mentioned technical matters by the following technical solutions, and marine gear box comprises casing, input shaft, output shaft, transmission shaft, is fixed on the parts such as gear, oil pump and power-transfer clutch on the axle.In casing, set up an oil pump drive spindle, input end is positioned at place, former built-in oil pump space, and the transmission gear of oil pump drive spindle input end is meshed with the transmission gear of gearbox input shaft, and oil pump drive spindle mouth frame is in the box inside bearing carrier ring, axle head stretches out casing, and axial end is established an open slot.Oil pump connects by open slot and oil pump rotating shaft, and pump body is screwed with the connecting panel that is located at the casing outside.Simultaneously, also the power-transfer clutch internal friction sheet on the output shaft is increased to 12 pinch planes from 10 pinch planes.Friction disk is placed as interior 6, is 7 outward.
The technical solution of the utility model makes built-in oil pump become the peripheral hardware oil pump, and the oil pump drive spindle input end then utilizes the space of crude oil pump, and mouth is located at box inside, therefore makes the space setting of former type need not change.Behind the oil pump peripheral hardware, not only make the oil pump repair and replacement very convenient, and can the selection standard oil pump, condition created for change required adjustment oil pump coupling because of horsepower output.Another technique effect of the utility model scheme is that power-transfer clutch internal friction sheet pinch plane increases to 12, can make output shaft transfer torque power increase more than 15%.

Among Fig. 2, oil pump (4) is located at casing (1) outside, the mouth of oil pump drive spindle (13) links to each other with axle sleeve on the casing, axle head stretches out outside the case, the rotating shaft of oil pump links to each other with the open slot (14) of the axial end of oil pump drive spindle (11), and the input end of oil pump drive spindle (12) is meshed with input shaft (2) transmission gear by transmission gear.
Among Fig. 3, power-transfer clutch (6) places on the input shaft (2), and Friction disk (7) is located in the power-transfer clutch.
The specific embodiment
The utility model can be described further with the following Examples, the marine gear box of 135A type is provided with an input shaft (2) in the casing (1), be fixedly connected with power-transfer clutch (6) on the axle, this power-transfer clutch drives driving gear, and this driving gear is meshed with the driven gear of output shaft (3).Oil pump (4) is located at outside the casing (1), by the transmission gear and the transmission gear engagement that connects firmly on input shaft (2) of oil pump drive spindle input end (12).Two bearings of the mouth of oil pump drive spindle (13) place box inside, and axle head stretches out outside the casing, and axial end is established an open slot (14).The rotating shaft of oil pump (4) and open slot (14) socket, the connecting panel on pump body and the casing (15) is screwed.6 outer 7 arranged in power-transfer clutch (6) internal friction sheet (7) adopted, and the pinch plane of Friction disk is 12.
