Abstract
The utility model provides a labyrinth cover capable of reducing external ejection of lubricating oil in a crankcase. The labyrinth cover is fixed to the position of a ventilation hole in the lower portion of the crankcase through screws matched with installation holes at four corners. The upper portion of the labyrinth cover is provided with a small through hole communicated with the air, the outer end of the small through hole is provided with a connector connected with a respirator, a plurality of labyrinth ribs are arranged in a cavity of the labyrinth cover from top to bottom so as to enable the lower portion of the cavity of the labyrinth to be communicated to the upper portion of the cavity of the labyrinth cover in a zigzag mode, the labyrinth ribs tilt downwards by 10-30 degrees, and the ends of the labyrinth ribs are turned downwards. The labyrinth ribs are additionally arranged in the cavity of the labyrinth cover from top to bottom, the lubricating oil , ejecting outwards due to pressure, in the crankcase swells to perform pressure relief in the cavity of the labyrinth cover, meanwhile, the lubricating oil is blocked by the labyrinth ribs and can condense and collect on the labyrinth ribs easily, the lubricating oil flows to the lower portion of the labyrinth cover along the labyrinth ribs tilting downwards, when the pressure in the crankcase is reduced, the lubricating oil flows back to the inside of the crankcase, so that leakage is avoided, and therefore the labyrinth cover is beneficial to environment protection and resource conservation.
Description
Technical field
The utility model relates to a kind of parts of crankcase, specifically relates to a kind of labyrinth lid that can reduce the outer spray of lubricant oil in crankcase.
Background technique
Crankshaft & connecting is when operation, what the pressure in crankcase was either large or small is changing, and for the pressure in the balance crankshaft case changes, a spiracle need to be set in the crankcase bottom, in order to prevent the oil leakage in crankcase, a lid need to be set at the spiracle place simultaneously.In prior art, the cap structure that is arranged on place, crankcase respiratory hole is comparatively simple, and the labyrinth muscle is not set in the lid cavity, when the lubricant oil pressurized in crankcase is sprayed with outward, can go out by the resuscitation apparatus string on lid, causes leakage, befouling environment, waste resource.
Summary of the invention
The utility model is mainly to solve the existing technical problem of above-mentioned prior art, and a kind of labyrinth lid that can reduce the outer spray of lubricant oil in crankcase is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of labyrinth lid that can reduce the outer spray of lubricant oil in crankcase, Gai De top, labyrinth is provided with and connects open to atmosphere small through hole, place, small through hole outer end is provided with the interface that connects resuscitation apparatus, in the cavity of described labyrinth lid, be provided with some labyrinth muscle from top to bottom, make the sinuous top that is communicated to labyrinth lid cavity, bottom of labyrinth lid cavity.
As preferably, the downward-sloping 10-30 degree of described labyrinth muscle, and Jin De end, labyrinth turns down downwards.
The utility model has been set up some labyrinth muscle from top to bottom in the cavity of labyrinth lid; the lubricant oil of the outer spray of the pressurized release of at first expanding in the cavity of labyrinth lid in crankcase; be subjected to simultaneously stopping of labyrinth muscle; lubricant oil is easy to condense and collect on the muscle of labyrinth; and be flowed to Gai De bottom, labyrinth along downward-sloping labyrinth muscle; when pressure reduces in crankcase, be back to again the crankcase the inside, can not cause leakage, be conducive to protection of the environment and economize on resources.Therefore, the utlity model has the characteristics such as simple in structure, reasonable in design.
The accompanying drawing explanation
Fig. 1 is a kind of main TV structure schematic diagram of the present utility model;
Fig. 2 is a kind of side-looking structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1 and Fig. 2, the utility model labyrinth lid 1 is fixed on the spiracle place of crankcase bottom via the mounting hole 2 at four jiaos of places of screw fit, the top of labyrinth lid 1 is provided with and connects open to atmosphere small through hole 3, small through hole 3 places, outer end are provided with the interface 4 that connects resuscitation apparatus, in the cavity of described labyrinth lid 1, be provided with some labyrinth muscle 5 from top to bottom, make the sinuous top that is communicated to labyrinth lid 1 cavity, bottom of labyrinth lid 1 cavity.The downward-sloping 10-30 degree of labyrinth muscle 5 wherein, and the end of labyrinth muscle 5 turns down downwards.The utility model has been set up some labyrinth muscle from top to bottom in the cavity of labyrinth lid; the lubricant oil of the outer spray of the pressurized release of at first expanding in the cavity of labyrinth lid in crankcase; be subjected to simultaneously stopping of labyrinth muscle; lubricant oil is easy to condense and collect on the muscle of labyrinth; and be flowed to Gai De bottom, labyrinth along downward-sloping labyrinth muscle; when pressure reduces in crankcase, be back to again the crankcase the inside, can not cause leakage, be conducive to protection of the environment and economize on resources.Therefore, the utlity model has the characteristics such as simple in structure, reasonable in design.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, and many distortion can also be arranged.Every foundation technical spirit of the present utility model, to any simple modification, equivalent variations and modification that above embodiment does, all should be thought and belong to protection domain of the present utility model.
Claims (2)
1. the labyrinth that can reduce the outer spray of lubricant oil in crankcase is covered, Gai De top, labyrinth is provided with and connects open to atmosphere small through hole, place, small through hole outer end is provided with the interface that connects resuscitation apparatus, it is characterized in that being provided with some labyrinth muscle from top to bottom in the cavity that covers in described labyrinth, make the sinuous top that is communicated to labyrinth lid cavity, bottom of labyrinth lid cavity.
2. a kind of labyrinth that can reduce the outer spray of lubricant oil in crankcase is covered according to claim 1, it is characterized in that the downward-sloping 10-30 degree of described labyrinth muscle, and Jin De end, labyrinth turns down downwards.
