Abstract
The utility model discloses a multi-oil hole main shaft bushing for an engine. The multi-oil hole main shaft bushing comprises a main shaft bushing body. A main shaft bushing oil groove is formed on the middle part of the main shaft bushing body. A first main shaft bushing oil hole is formed in one end of the main shaft bushing oil groove. A second main shaft bushing oil hole is formed in the other end of the main shaft bushing oil groove. By the multi-oil hole main shaft bushing, the formation of an oil film thickness and the removal of granular impurities can be facilitated, temperature between a connecting rod and a connecting rod shaft bushing can be reduced, the lubrication of the connecting rod shaft bushing can be improved, and the service life of the connecting rod shaft bushing can be prolonged; and the multi-oil hole main shaft bushing can be widely applied to a crank connecting rod device of an automotive engine.
Description
Technical field
The utility model relates to the motor car engine crank connecting rod apparatus, particularly relates to a kind of engine multi-oil cellular type structure main axle bush.
Background technique
Existing engine spindle watt is single oilhole formula structure; Referring to Fig. 1; Existing engine spindle watt comprises and to be provided with main axle bush oil groove 2 at the middle part of main axle bush body 1 by main axle bush body 1, is provided with the first main axle bush oilhole 3 at an end of main axle bush oil groove 2; The said first main axle bush oilhole 3 mainly is in order to carry enough lubricant oil for the connecting rod bearing shell (not shown), to guarantee the effectively lubricating of connecting rod bearing shell and reduce the temperature between connecting rod and the connecting rod bearing shell.Yet the oil mass that existing single oilhole formula structure is supplied with is few, causes the lack of lubrication of connecting rod bearing shell, and heat radiation is slow, can not effectively reduce the temperature between connecting rod and the connecting rod bearing shell.
The model utility content
The purpose of the utility model is in order to overcome the deficiency of above-mentioned background technology; A kind of engine multi-oil cellular type structure main axle bush is provided; Make its formation that can help oil slick thickness, reduce the temperature between connecting rod and the connecting rod bearing shell, improve the lubricated of connecting rod bearing shell; And help the eliminating of granule foreign, increase the working life of connecting rod bearing shell.
A kind of engine multi-oil cellular type structure main axle bush that the utility model provides; Comprise the main axle bush body; Be provided with the main axle bush oil groove at the middle part of main axle bush body, be provided with the first main axle bush oilhole, be provided with the second main axle bush oilhole at the other end of main axle bush oil groove at an end of main axle bush oil groove.
The engine multi-oil cellular type structure main axle bush of the utility model; Has following beneficial effect: increase the oilhole quantity on the engine spindle watt; Can provide more machine oil to be supplied to connecting rod bearing shell; This structure can be improved the lubricated of connecting rod bearing shell on the one hand, helps the formation of oil slick thickness and reduces the temperature between the friction pair; This on the other hand structure helps the eliminating of granule foreign, reduces friction or scratch between engine spindle watt, connecting rod bearing shell, main journal and the rod journal, has increased the working life of each friction pair.
Description of drawings
Fig. 1 is the structural representation of the engine spindle watt of existing technology;
Fig. 2 is the structural representation of the utility model engine multi-oil cellular type structure main axle bush;
Fig. 3 is the oil supply structure explosive view between bent axle, engine multi-oil cellular type structure main axle bush and the cylinder body.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe in detail, but this embodiment should not be construed as the restriction to the utility model.
Referring to Fig. 2, the engine multi-oil cellular type structure main axle bush of the utility model comprises main axle bush body 1.
Be provided with main axle bush oil groove 2 at the middle part of main axle bush body 1, be provided with the first main axle bush oilhole 3, be provided with the second main axle bush oilhole 4 at the other end of main axle bush oil groove 2 at an end of main axle bush oil groove 2.
Referring to Fig. 3, be followed successively by from top to bottom shown in the figure and comprise bent axle 5, main axle bush body 1 and cylinder body 8.Bent axle 5 is provided with the rod journal oilhole 7 that main journal oilhole 6 and an end are connected with main journal oilhole 6 tops, and the other end of rod journal oilhole 7 is connected with the connecting rod bearing shell (not shown).Cylinder body 8 tops are provided with main bearing seat oil groove 9, also are provided with the main bearing seat oilhole 10 that two ends are connected with main bearing seat oil groove 9 and main oil gallery 11 respectively on the cylinder body 8.
Machine oil gets into main bearing seat oil groove 9 by main oil gallery 11 through main bearing seat oilhole 10.Under the effect of engine oil pressure; Main bearing seat oil groove 9 is full of machine oil with main axle bush oil groove 2, and when bent axle 5 turns to main journal oilhole 6 when being connected with the first main axle bush oilhole 3, the machine oil in the main bearing seat oil groove 9 is to main axle bush body 1 fuel feeding; And flow to main journal oilhole 6 via main axle bush body 1; Flow into rod journal oilhole 7 by main journal oilhole 6 subsequently, give the connecting rod bearing shell fuel feeding through rod journal oilhole 7 at last, guarantee the lubricated and cooling of connecting rod bearing shell.If have only first main axle bush oilhole 3 on the main axle bush body 1 this moment, this covering device is existing engine spindle watt, for once promptly accomplishes the fuel feeding process.If when also being provided with the second main axle bush oilhole 4 on the main axle bush body 1; When bent axle 5 turns to main journal oilhole 6 when being connected with the second main axle bush oilhole 4; Machine oil will be given the connecting rod bearing shell fuel feeding by main oil gallery 11 once more in a similar fashion; This will improve the lubrication circumstances of connecting rod bearing shell, and quicken the cooling of bent axle 5 and relevant friction pair.Simultaneously, the setting of the second main axle bush oilhole 4 more helps getting rid of the residual impurity that causes because of reason lack of standardization, has reduced friction or scratch between main axle bush body 1, connecting rod bearing shell and the bent axle 5, has increased the working life of each friction pair.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.
The content of not doing in this specification to describe in detail belongs to related domain professional and technical personnel's known prior art.
