Description
Technical field
The present invention relates to a kind of engine components, specifically, relate in particular to the cover of oil filter on the motor.
Background technique
Motor is in the process of running, and the machine oil in the lubrication system can be constantly dirty, and there are several aspects in the source of pollution: the one, and exogenous impurity locates to enter crankcase as airborne dust by respirating tube, oil filler etc.; Next is the metal fillings that parts depreciation is got off; Product in the oxidizing process of machine oil own besides, as various organic acids, burnt matter pitch and carbide etc.; The water of oil sump in addition bleeds.These impurity can promote the wearing and tearing of component, and the corrosion of generation can be killed movement parts.The effect of oil filter just is the above-mentioned objectionable impurities that is present in the machine oil of filtering, and protection main frame component prolong its working life.
Traditional motorcycle engine generally adopts spin-on oil filter, and this spin-on oil filter is installed on the bent axle, and with the bent axle high speed rotating, the centrifugal force that produces by rotation removes the impurity in the machine oil.Because spin-on oil filter is positioned at crankcase, when needing to be serviced or change, must dismantle crankcase cover and bent axle, so not only complex operation, workload are big, inefficiency, and frequent easy disassembling causes crankcase seals bad, and destroy the dynamic balancing of bent axle, the stationarity of crankshaft operation is descended, the vibration that can strengthen engine operation on the other hand, also can be shortened the working life of bent axle on the one hand.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of oil filter cover structure, conveniently oil filter safeguarded or to be changed.
Technological scheme of the present invention is as follows: a kind of oil filter cover structure, have lid, and described lid is up big and down small stepped cylinder structure, is provided with journal stirrup on lid is appeared on the stage the excircle in stage, offers the installation via hole on this journal stirrup; The leave from office stage at described lid is provided with oil duct, and the import of this oil duct is positioned on the lid outer peripheral surface in leave from office stage, and the outlet of oil duct is positioned at the bottom surface of lid.
The present invention is the parts that improvement is increased newly according to crankcase cover structure, sets up an oil filter mounting groove on crankcase cover, the filter net type filter core is installed in this mounting groove, and the notch of mounting groove is sealed by the present invention.Oil duct import of the present invention communicates with the crankcase cover inner chamber by the oil inlet hole on the crankcase cover, oil duct outlet of the present invention communicates with the inside of filter core, machine oil in the engine sump flows in the oil duct of the present invention by the oil inlet hole on the crankcase cover under the effect of oil pump like this, flow in the filter core by oil duct again, after filter core filters out impurities, directly import in the crankshaft oil gallery by the oil outlet on the crankcase cover, bent axle is cooled off, lubricates.
The present invention and filter core, crankcase cover are formed the novel static filter net type oil strainer device that disappears, can realize the function of conventional centrifugal oil filter, and clean, safeguard at needs or more during renew cartridge, only need the present invention is removed and can carry out, need not to dismantle crankcase cover and bent axle, so not only simple to operate, workload is little, efficient is high, and guaranteed that the dynamic balancing of the sealing of crankcase and bent axle is unaffected, make bent axle to turn round reposefully all the time, prolonged working life.
Processing for convenience, above-mentioned oil duct is made up of horizontal hole and upright opening, and the import of described horizontal hole is on the lid outer peripheral surface in leave from office stage, and the outlet of horizontal hole communicates with the upper vertical of upright opening, and the lower end of described upright opening connects the bottom surface to lid.
Central authorities in above-mentioned lid bottom surface are formed with round boss, and the lower end of described upright opening connects the bottom surface to this boss.Round boss to the filter core location, has guide function on the one hand on the other hand, machine oil can be imported in the filter core, filters.
Offer annular groove on the circumferential surface in above-mentioned lid leave from office stage, this annular groove is positioned at the top of oil duct.Annular groove is for the assembling of O type circle, to realize the crankcase cover mounting groove is formed the sealing effect of cylndrical surface; Simultaneously, the transitional surface of lid up/down steps section is a planar annular, can press-fit the sealing paper washer when being assembled on the crankcase cover, with further raising plane sealing effect.
Offer circular deep gouge on the end face of above-mentioned lid, circular deep gouge plays beautiful decoration.
Beneficial effect: the present invention provides convenience for the maintenance and the replacing of filter core, make cleaning, the operation simple and fast more of renew cartridge more, and the dynamic balancing that has guaranteed the sealing of crankcase and bent axle is unaffected, have be skillfully constructed, simple in structure, implement easily, characteristics such as good reliability.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is a user mode reference drawing of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, a kind of oil filter cover structure has lid 1, lid 1 is up big and down small stepped cylinder structure, offer circular deep gouge 1c on the end face of lid 1, this deep gouge 1c plays beautiful decoration, and the central authorities of lid 1 bottom surface are formed with round boss 1a.The stage of appearing on the stage of described lid 1 is shorter, and the leave from office stage is longer, is symmetrically arranged with two journal stirrups 2 on lid 1 is appeared on the stage the excircle in stage, and this journal stirrup 2 be a monolithic construction with lid 1, and offers installation via hole 2a on each journal stirrup 2.On the circumferential surface on described lid 1 leave from office stage top, offer annular groove 1b, assemble for O type circle.The bottom that lid 1 is left office the stage is provided with oil duct 3, this oil duct 3 is made up of horizontal hole and upright opening, the import of described horizontal hole is on the lid outer peripheral surface in 1 leave from office stage, and the outlet of horizontal hole communicates with the upper vertical of upright opening, and the lower end of described upright opening connects to the bottom surface of boss 1a.
