Specific embodiment
Embodiment shown in reference to the accompanying drawing is further described the utility model:
Referring to figure 1, a kind of marine gearbox comprising gear housing is arranged in the intracorporal transmission group of gear-box
Part and the fuel reserve tank 1 being connected to gear housing are provided with the overflow oil return pipe 2 of connection gear housing bottom in fuel reserve tank 1, also wrap
It includes the compressed air system 3 for air to be filled with or extracted out into gear housing and extracts the lubricating oil spray biography of fuel reserve tank 1
The spray system of dynamic component.
Spray system includes that circulating oil path 51 and the spray equipment 52(spray equipment being arranged on circulating oil path 51 setting exist
In gear-box, indicate conveniently to be labeled in figure outer), the cooling device 53 for cutting oil, the dress of the filtering for filtering
The transfer tube 55 setting 54 and being arranged on circulating oil path 51.
Gear housing includes the intermediate gear box 43 of both upper gear box 41, lower tooth roller box 42 and connection, intermediate gear box
Vertical transmission shaft is provided in 43.Compressed air system 3 is connected with the top of intermediate gear box 43.
Fuel reserve tank 1 is in a ring that ring is located at the middle part of gear-box, and specifically, ring is located at the outside of intermediate gear box 43.
The liquid level sensor component 6 of liquid level in detector and the temperature sensor group of detection temperature are provided in fuel reserve tank 1
Part is provided with the pressure sensor assembly of the detection intracorporal pressure of gear-box in gear housing.And be provided on fuel reserve tank 1 with
The pressure maintaining valve 7 of atmosphere.
When the marine gearbox of the present embodiment is out of service, lubricating oil in fuel reserve tank 1 some can pass through overflow
Oil return pipe 2 flows into lower tooth roller box 42, and 1 oil level of fuel reserve tank is being maintained at preset shutdown oil level, when liquid level sensor component 6 detects
To shut down oil level it is too low when, when booting, issues system alarm.
Before the present embodiment unlatching, compressed air system 3 is first opened, compressed air, compressed air are filled with into gear-box
The lubricating oil of lower tooth case can be pressed into fuel reserve tank 1, when 1 oil level of fuel reserve tank rises to preset operation oil level, under lower tooth fuel level in tank
