Abstract
The utility model belongs to field of ship power transmission manufacturing technology and relates to a gearbox for reinforced ship, which comprises box body, import shaft coupling, input shaft, transmitting gear, driving gear, second grade driving gear, driven gear, output shaft and clutch, the second grade driving gear set is located out of transmission shaft, the clutch is arranged one end of second grade driving gear, the one end of second grade driving gear is prolonged for 125-130mm with surface treated spline. The utility model can reduce volume of gearbox; improve use reliability of marine gearbox.
Description
Technical field
The utility model belongs to ship power transmission device manufacturing technology field, relates to middle power reinforced marine gearbox a kind of and the marine diesel engine coupling.
Background technique
Marine gearbox is a kind ofly to have suitable, clutch, deceleration and can bear the boat transmission of propeller thrust.In the common rotating speed of powerful marine diesel engine higher, and can not reverse, therefore, must be supporting during use with marine gearbox, could form power unit peculiar to vessel.The marine gearbox of power at present on the domestic and international market, as types such as T300, this class formation has many unreasonable design parts.Be with a clutch base on one end of its driving gear, and the cylindrical of this end of driving gear can not be done very greatly, otherwise influence the processing of driving gear, and the friction plate endoporus in the clutch can not be done very for a short time, otherwise can influence the transmission capacity of gear-box.
Summary of the invention
The purpose of this utility model is to design a kind of volume reinforced marine gearbox little, in light weight, simple in structure.
For solving the problems of the technologies described above, the utility model is realized by the following technical solutions: a kind of reinforced marine gearbox, comprise casing, input coupling, input shaft, driving gear, driving gear, the secondary driving gear, driven gear, output shaft, clutch, the secondary driving gear is sheathed on outside the transmission shaft, clutch is located at an end of secondary driving gear, one end of described secondary driving gear prolongs 125-130mm, surface Machining has spline, spline is that pressure angle is 30 ° a brachmorphy tooth, replaced the clutch base in the conventional construction, and improve the prescription of Friction Disk Surface friction layer, improve its friction factor and reduce its heating value, dwindle the cylindrical and the endoporus of friction plate, it is increased to friction plate is the 8-12 group, thereby allow friction plate directly be connected, dwindled the volume of gear-box, improved the operational safety of marine gearbox with driving gear.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a partial enlarged drawing of the present utility model.
Fig. 3 is an another partial enlarged drawing of the present utility model.
As shown in Figure 1, 2, 3, friction plate 8b, driving gear 9, output shaft 10, driven gear 11, output shaft coupling 12, casing 13 in input coupling 1, input shaft 2, driving gear 3, idler shaft 4, idle gear 5, transmission shaft 6, secondary driving gear 7, spline 7a, clutch 8, clutch outside friction disc 8a, the clutch.Secondary driving gear 7 is sheathed on outside the transmission shaft 6, and clutch 8 is located at an end of secondary driving gear 7.
Embodiment
As shown in Figure 1, secondary driving gear 7 is sheathed on outside the transmission shaft 6, and clutch 8 is located at an end of secondary driving gear 7.
Shown in Fig. 2,3, an end of secondary driving gear 7 prolongs 126mm and is processed with spline 7a, and spline 7a is that pressure angle is 30 ° a brachmorphy tooth; Set about from the prescription of powder metallurgy, improve the prescription of Friction Disk Surface friction layer, improve its friction factor and reduce its heating value, the quantity of the outside friction disc 8a of clutch 8 is made as 11 groups, the quantity of the interior friction plate 8b of clutch is made as 10 groups, thus the operational safety that has realized dwindling the volume of gear-box and improved gear-box.
Claims (2)
1, a kind of reinforced marine gearbox, comprise casing, input coupling, input shaft, driving gear, driving gear, secondary driving gear, driven gear, output shaft, clutch, the secondary driving gear is sheathed on outside the transmission shaft, clutch is located at an end of secondary driving gear, it is characterized in that: an end of secondary driving gear prolongs 125-130mm, and surface Machining has spline.
2, reinforced marine gearbox according to claim 1 is characterized in that: the friction plate progression in the clutch is the 8-12 group.
