Description
Technical field
The utility model belongs to technical field of engines, particularly relates to a kind of gas and oil separating plant oil return mechanism.
Background technique
Present stage, when oil-gas separating device of engine takes rearmounted layout, the return tube be connected with gas and oil separating plant is communicated with by the return tube being arranged on motor side and flows back to oil sump.Because the length of return tube is longer, not only there is difficult arrangement and arrange chaotic problem, and very easily occurring the problem that on return tube and motor, other pipelines are interfered mutually; Meanwhile, the reliability of gas and oil separating plant work can not get good guarantee.Especially, when motor adopts major and minor Oil-gas Separation, owing to having two return tubes, interference problem and Layout Problem then can be more serious.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of gas and oil separating plant oil return mechanism, under the prerequisite ensureing gas and oil separating plant reliably working, solve the problem that on return tube difficult arrangement, chaotic problem and return tube and motor, other pipelines are interfered mutually.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of gas and oil separating plant oil return mechanism, comprise setting gas and oil separating plant on the engine, one is formed for the shoe cream room of oil storage between the flywheel casing that described motor and described motor are installed, the top of described flywheel casing is provided with one and runs through described flywheel casing wall thickness and the return tube extended to bottom described shoe cream room, is provided with a connecting tube between described return tube and described gas and oil separating plant;
Be provided with between the bottom surface of described return tube and described shoe cream room one for described return tube fuel-displaced go out oil-gap;
Be provided with one for discharging the oil outlet of described shoe cream room inner fluid with the described flywheel casing sidewall of described shoe cream room corresponding position, described oil outlet higher than described go out oil-gap.
Improve as one, described oil outlet is positioned at the inner side surface of described flywheel casing, and described shoe cream room is communicated with the gear chamber on described flywheel casing by described oil outlet.
As further improvement, described gas and oil separating plant comprises main deaerator and secondary deaerator, described connecting tube comprises the First Transition pipe be connected with described main deaerator and the second transition tube be connected with described secondary deaerator, and described First Transition pipe, described second transition tube and described return tube are interconnected by three-way pipe.
As further improving, described First Transition pipe is provided with an one-way valve.
As further improving, described return tube is metal return tube, and described connecting tube is rubber linking tube.
After have employed technique scheme, the beneficial effects of the utility model are:
Owing to forming a shoe cream room between motor and flywheel casing, shoe cream room is connected with gas and oil separating plant with return tube by the connecting tube be interconnected, thus the isolated fluid of gas and oil separating plant flows to the bottom of shoe cream room through connecting tube and return tube, when shoe cream room inner fluid runs up to certain liquid level, just return tube can be exported fluid-tight, effectively can prevent from oil gas from escaping like this or return altering, when the fluid in shoe cream room is abundant, be flowed out by oil outlet.Compared with traditional return tube, this structure can shorten the length of return tube between gas and oil separating plant and oil sump greatly, decrease cost, not only take full advantage of the unused cavity between motor and flywheel casing, also can improve motor upper pipeline difficult arrangement, chaotic situation, make that motor upper pipeline is arranged more rationally, outward appearance is more succinct, meanwhile, avoid the problem that on return tube and motor, other pipelines are interfered mutually; In addition, the reliability of gas and oil separating plant work is also improved.
Because shoe cream room is communicated with the gear chamber on flywheel casing by oil outlet, thus when fluid in shoe cream room is abundant, enters gear chamber lubricate train of gearings by oil outlet, the secondary achieving fluid utilizes, and avoids waste.
Because First Transition pipe is provided with an one-way valve, thus by one-way valve, prevent operationally, oil gas only through main deaerator without secondary deaerator, directly enter shoe cream room.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment one:
As Fig. 1 and Fig. 2 jointly shown in, a kind of gas and oil separating plant oil return mechanism, comprise the gas and oil separating plant 5 be arranged on motor 1, this gas and oil separating plant 5 is single-stage deaerator, formed between the flywheel casing 2 that this motor 1 and motor 1 are installed seal and for the shoe cream room 201 of oil storage, the top of this flywheel casing 2 is provided with one and runs through flywheel casing 2 wall thickness and extend to the return tube 3 bottom shoe cream room 201, is provided with a connecting tube 4 between this return tube 3 and gas and oil separating plant 5; Be provided with between this return tube 3 and bottom surface of shoe cream room 201 one for return tube 3 fuel-displaced go out oil-gap 204; Be provided with one for discharging the oil outlet 202 of shoe cream room 201 inner fluid with flywheel casing 2 sidewall of shoe cream room 201 corresponding position, this oil outlet 202 is higher than going out oil-gap 204.
This oil outlet 202 is positioned at the inner side surface of flywheel casing 2, and this shoe cream room 201 is communicated with the gear chamber 203 on flywheel casing 2 by oil outlet 202.
This return tube 3 is metal return tube, and this return tube 3 can be processed separately, also can form with flywheel casing 2 integrally casting; This connecting tube 4 is rubber linking tube.
Embodiment two:
The structure of the present embodiment is substantially identical with the structure of embodiment one, and its difference is:
