The consumption of few lubricating oil.
The utility model solves above-mentioned technical problem using following technical scheme：
A kind of backgear room with gas oil separation structure, including backgear chamber body, gas oil separation structure, oil gas air inlet pipe and
Air outlet adapter；
The gas oil separation structure is arranged on backgear chamber body top；
The gas oil separation structure includes rugged reinforcing rib and oilhole；
The oil gas air inlet pipe and air outlet adapter are connected on gas oil separation structure.
Further, the rugged reinforcing rib is the reinforcing rib of at least one L-type.
Further, the oil gas air inlet pipe is vertically set in backgear chamber body, and top is connected with valve mechanism cover.
Further, one end that the air outlet adapter is not connect with gas oil separation structure is provided with oil gas outlet sebific duct.
Further, backgear room bottom is provided with oil sump.
Further, the backgear chamber body includes shell, high-pressure oil pump gear, camshaft timing gear and crankshaft timing
Gear, the high-pressure oil pump gear and crankshaft timing gear are separately positioned on both sides below camshaft timing gear.
Further, there are two hydraulic pumps to install interface for setting in the backgear chamber body.
Further, backgear room side is provided with bell housing.
Further, the backgear room is mounted on by crankshaft rear end flange on diesel engine frame with bell housing.
The utility model has the advantage of：
The utility model is simple in structure, good oil gas separation effect, has reached maintenance crankcase pressure and has reduced lubricating oil
Consumption, the alternative independent respiratory organ structure of diesel engine, to reduce diesel engine cost, can be promoted in similar product makes
With.
Description of the drawings
Fig. 1 is a kind of sectional view of the backgear room with gas oil separation structure of the utility model embodiment；
Fig. 2 is the knot that a kind of backgear room with gas oil separation structure of the utility model embodiment is mounted on diesel engine frame
Structure schematic diagram.
Specific implementation mode
The utility model is described in detail below in conjunction with attached drawing.
As shown in Figs. 1-2, a kind of backgear room with gas oil separation structure of the utility model, including backgear chamber body 1, oil
Gas separation structure 2, oil gas air inlet pipe 3 and air outlet adapter 4；
The gas oil separation structure 2 is arranged on the top of backgear chamber body 1；
2 section of the gas oil separation structure is right angled triangle, and two right-angle sides are respectively horizontal and vertical direction, the oil
Gas separation structure 2 includes the reinforcing rib 21 and oilhole 22 of a horizontal L-type, reinforcing rib 21 and the gas oil separation structure 2 of L-type
Vertical right-angle side is orthogonal, and the reinforcing rib 21 of L-type makes 2 internal structure of gas oil separation structure form a type labyrinth structure,
Oil gas is set to reach separation, the lowermost end of the right angled triangle constituted in gas oil separation structure 2 is arranged in oilhole 22；
The oil gas air inlet pipe 3 is vertically set on the top on 2 level right angle side of gas oil separation structure；The air outlet adapter 4
It is connected to above 2 level right angle of gas oil separation structure, and positioned at the other side of oil gas air inlet pipe 3.
The oil gas air inlet pipe 3 is vertically set in backgear chamber body 1, and the top of oil gas air inlet pipe 3 is connected with cylinder
Housing 5.
Valve mechanism cover 5 is the place that engine oil, gas collect, and oil gas by oil gas air inlet pipe 3 enters oil gas point after collecting
From in structure 2.
One end that the air outlet adapter 4 is not connect with gas oil separation structure 2 is provided with oil gas outlet sebific duct 6, oil gas outlet
Sebific duct 6 is reversed inverted L-type structure sebific duct, and the long tube tail end of vertical direction is connected in backgear chamber body 1, and gas is by going out
Gas connector 4 is discharged by oil gas outlet sebific duct 6.Backgear room bottom is provided with oil sump 7, and oil sump 7 is machine oil storage
The place collected.
The backgear chamber body 1 includes shell 11, high-pressure oil pump gear 12, camshaft timing gear 13, crankshaft timing tooth
Wheel 14 and two hydraulic pumps install interfaces 15, the high-pressure oil pump gear 12 and crankshaft timing gear 14 respectively with camshaft timing
Gear 13 engages and the both sides below camshaft timing gear 13 is arranged.
1 side of backgear room is provided with bell housing 8.
The backgear room 1 is mounted on by crankshaft rear end flange 9 on diesel engine frame 10 with bell housing 8, crankshaft rear end method
Orchid 9 is located at the center of bell housing 8, and bell housing 8 plays the role of vehicle installation and docking, backgear room 1, bell housing 7
So that backgear room 1 forms independent gas oil separation structure after being installed together with diesel engine frame 10.
