The consumption of lubricating oil.
The present invention 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 housing, 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 pump installation interfaces 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 application method of this backgear room with gas oil separation structure, step include：From oil gas air inlet after gas collection
Pipe enters, and oil gas is settled after entering gas oil separation structure by machine oil its own gravity, and oil gas is made to reach separation, then so that gas
It is discharged at air outlet adapter, it is oily then discharged through oil-through hole.
The advantage of the invention is that：
The configuration of the present invention is simple, good oil gas separation effect have reached maintenance crankcase pressure and have reduced disappearing for lubricating oil
Consumption, the respiratory organ structure of alternative diesel engine independence so as to reduce diesel engine cost, can be promoted the use of in similar product.
Description of the drawings
Fig. 1 is a kind of sectional view of the backgear room with gas oil separation structure of the embodiment of the present invention；
Fig. 2 is that the structure that a kind of backgear room with gas oil separation structure of the embodiment of the present invention is mounted on diesel engine frame is shown
It is intended to.
Specific embodiment
The present invention 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 present invention, including backgear chamber body 1, oil gas point
From 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 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 causes 2 internal structure of gas oil separation structure to form a type labyrinth structure,
Oil gas is made to reach separation, oilhole 22 is arranged on the lowermost end for the right angled triangle that gas oil separation structure 2 is formed；
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 opposite 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 the place that machine oil storage collects.
The backgear chamber body 1 includes housing 11, high-pressure oil pump gear 12, camshaft timing gear 13, crankshaft timing tooth
Wheel 14 and two hydraulic pumps installation interfaces 15, the high-pressure oil pump gear 12 and crankshaft timing gear 14 respectively with camshaft timing
