Abstract
The utility model belongs to the technical field of marine power transmission and relates to a marine gearbox which is matched with a medium-powered diesel engine. A set of oil pump transmission devices are arranged in a box body, a transmission gear on the input end of a transmission shaft of an oil pump and a transmission gear of an input shaft of the gearbox are engaged, and the output end extends the box body and is connected with the oil pump. Because the tooth number of the transmission gear of the oil pump is smaller one-half than the tooth number of the transmission gear, thereby, the oil pump is operated faster and faster. At the same time, the adjoining surface of a friction disk of a clutch is increased to 16 surfaces, which makes the cooling area enlarged. When the utility model is implemented, the function of the gearbox can be strengthened, and the transmission capacity is improved by 20 %.
Description
Technical field
The utility model belongs to marine powerplant manufacturing technology field, relates in particular to the marine gear box a kind of and mid power that diesel engine for boats is complementary.
Technical background
Marine gear box is a kind ofly to have suitable, clutch, deceleration, and can bear the marine gearing of propeller thrust.So far, the mid power marine gear box of China market has different types of machines, is one of mainstream models of mid power marine gear box as 300 type ship gears.This class type is because the structure design that adopts oil pump to link to each other with the input shaft tail end; when the diesel engine low-speed running; usually oil pump can occur and descend, thereby cause gear case clutch fading and gear case heating because of rotating speed causes gear case operating oil pressure and lubrication pressure inadequately.Therefore, design and a kind ofly still can guarantee the fuel feeding abundance when the diesel engine minimum operating speed, strengthen the reinforced marine gearbox of gear case transmission capacity, be the problem that the insider inquired into always.
Summary of the invention
The utility model is at the said structure defective of 300 type ships with gear case, under the prerequisite that does not change former type size, spatial volume, layout and power-transfer clutch, cooling vessel to oil pump make improvements, and design a kind of J300A reinforced marine gearbox that VHO Very High Output is arranged again rational in infrastructure.
The utility model solves the problems of the technologies described above by the following technical solutions.A kind of improved type marine gear box, comprise casing, input coupling, input shaft, driving gear, transmission gear, clutch base, power-transfer clutch, output shaft and driven gear, it is characterized in that in casing, setting up an oil pump drive spindle, oil pump drive spindle by two bearings on cabinet wall, the oil pump driving gear of oil pump drive spindle input end is meshed with transmission gear on the gearbox input shaft, the mouth of oil pump drive spindle stretches out casing and links to each other with oil pump, realizes that the input shaft of gear case drives the running of oil pump speedup.Simultaneously, the clutch-lining face of joint is designed to 14 to 16, and the best is 16, and sheet was 8 in friction lining was placed as, 7 of outer plates, 2 of monolithics.Can make the cooling area of cooling vessel increase to 0.5 sq m like this by 0.3 original sq m.
The technical solution of the utility model salient point is to have set up a cover oil pump driving device to link to each other with input shaft in casing, thereby makes the oil pump speedup, and oil pump also can provide the pressure of marine gear box normal operation when the diesel engine low-speed running.Another characteristics of the utility model are that the clutch-lining face of joint increases to 16, make the cooling area of cooling vessel increase to 0.5 sq m.Owing to adopted technique scheme, the marine gear box transmission capacity is increased more than 20%, have higher technique effect.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model oil pump drive mechanism scheme drawing.
Fig. 3 is the utility model clutch configuration scheme drawing.
In the diagram 1, input coupling (1), input shaft (2), driving gear (3), transmission gear (4), clutch base (5), power-transfer clutch (6), clutch outer member (7), output shaft (8), driven gear (9), casing (10).
In the diagram 2, establish an oil pump drive spindle (12) in the casing, with two bearings (11) oil pump drive spindle (12) is fixed on casing (10) inwall, the oil pump driving gear of input end (13) is meshed with the transmission gear (4) of gearbox input shaft, and the mouth of oil pump drive spindle (12) links to each other with casing oil pump (14) outward.
In the diagram 3, power-transfer clutch (6) places between clutch outer member (7) and the clutch base (6), and power-transfer clutch is made up of 8 interior sheets, 7 outer plates, 2 monolithics, and face of joint is 16.
The specific embodiment
The utility model is described further with the following Examples: J300A type ship gear case, one cover oil pump driving device is set in casing (10), form by bearing (11), oil pump drive spindle (12), oil pump driving gear (13), oil pump (14), transmission gear (4), the transmission gear of gearbox input shaft (14) links to each other with oil pump driving gear (13) engagement, the oil pump (14) outer by the mouth and the gear case of oil pump drive spindle (12).Because the number of teeth of the ratio of number of teeth transmission gear (4) of oil pump driving gear (13) lacks 1/2nd, both are meshed, and can make the running of oil pump speedup.Simultaneously the friction lining face of joint in the power-transfer clutch (6) is increased to 16, make the cooling area of cooling vessel increase to 0.5 sq m.The J300A type ship is strengthened with the function of gear case, improve more than 20% than the transmission capacity of original design.
Claims (3)
1. improved type marine gear box, comprise casing (10), input coupling (1), input shaft (2), driving gear (3), transmission gear (4), clutch base (5), power-transfer clutch (6), output shaft (8) and driven gear (9), it is characterized in that being provided with in the casing (10) oil pump drive spindle (12), the oil pump driving gear (13) of axle input end is meshed with gearbox drive gear (4), and the axle mouth links to each other with casing oil pump (14) outward.
2. marine gear box according to claim 1 is characterized in that described oil pump drive spindle (12) props up at casing (10) inwall with bearing (11).
