Marine gearbox T400

Qualified marine gearbox with competitive price and best service.

Marine gearbox model T400 for Marine Diesel Engines

Marine gearbox T400, which performs the duties of reduction, ahead and astern, engaging and disengaging, and carrying the propeller thrust, is designed in response to the matching requirement of middle and high speed engines either domestic or abroad.

It is somewhat novel in construction, smooth in engagement. The ratios of both ahead and astern are identical as well as the product can run under full load for a long time. Therefore it can be couple with engines of same rotation dierection to form right or left-hand power unit.

Marine gearbox T400:

1.Transmission mode: 7 helical gears with 4 shafts.

2.Clutch: Hydraulically-controlled wet-type multi plates.

3.Input coupling: Toothed rubber block coupling.

4.Input speed: 1000-2100rpm

5.Center distance:375mm

6.Ratios and the transmission capacity(with toothed rubber block coupling):

Normal ratio	Practical ratio	Trans.capacity kW/r*pm-1 (ps/r*pm-1)
6:1	6.087:1	0.331(0.450)
6.5:1	6.491:1
7:1	6.933:1
7.5:1	7.42:1	0.309(0.420)
8:1	7.950:1	0.287(0.390)
8.5:1	8.4:1	0.265(0.360)
9:1	9.0:1	0.243(0.33)
9.5:1	9.474:1	0.245(0.333)

Note: Both ratio and trans.capacity of astern are identical to those of ahead

7.Direction of rotation of input shaft(facing the output end): Anticlockwise

8.Direction of rotation of output shaft:same as that of input shaft

9.Rated propeller thrust:82,000N

10.Mechanical efficiency:≤96%

11.Time required for reversal:≤10S

13.Working oil pressure:1.3-1.5MPa

15.Oil grade: SC/CC30,SAE30;

                   SD/CC40, SAE40(for summer in the torrid zone)

16.Overal dimension(L*W*H): 800X1052X1130mm

17.Net weight:             1200kg;
