Abstract
The utility model discloses a crank head gland for oil engine comprising a gasket base connected to the current gear box. Wherein a baltimore groove is open outwards in the gasket base to install the gasket which is dynamic seal arranged with the peripheral surface of the crankshaft flange fixed on the crank. A positioning flange which has the same axis with the groove is provided in the inner surface of the gasket base to fit the current gear box. The crank head gland can ensure a homogeneous contact between the gasket and the crankshaft flange periphery. When in operation, the pressure is homogeneous and medium between the crankshaft and the gasket, improving seal performance.
Description
Technical field
The utility model relates to the seal arrangement technical field, relates in particular to a kind of seal arrangement that is used for the crankshaft of diesel engine front end.
Background technique
During the diesel engine operation, bent axle is at high speed rotating, and the machine oil of lubricated bent axle is also driven rotation together, and along the bent axle axial flow.Need a cover sealing configuration at the diesel engine front end like this, prevent that lubricating oil leakage is to the diesel engine outside.Leakage of oil, oil impregnate appear in original forward end seal sealing structure poor effect.The consequence that causes is: befouling environment, influence the diesel engine overall appearance, consumption of lubricating oil increases, the Economy variation.
The model utility content
Technical problem to be solved in the utility model is: the crankshaft of diesel engine forward end seal device that a kind of good sealing effect is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: crankshaft of diesel engine forward end seal device, comprise the oil sealing base that is connected in housing for timing gear, and described oil sealing base is provided with a uncovered laterally annular groove; Be installed on the oil sealing in the described groove, described oil sealing contacts with the outer circumferential face motive sealing of the crankshaft flange that is fixed in bent axle, the inboard of described oil sealing base be provided with one with the suitable locating flange of described housing for timing gear, described locating flange and described groove have same axis.
Locating flange can make oil sealing base and housing for timing gear realize accurately location, again because described locating flange has same axis with described groove, thereby the assurance oil sealing on whole circumference with respect to crankshaft flange outer peripheral surface even contact.
As a kind of improvement, described oil sealing base is that bolt is connected with housing for timing gear.Described housing for timing gear is provided with six edges circumferentially distribution and symmetrical in twos screw, described oil sealing base is provided with six through holes that adapt with described screwhole position, the bar portion of six bolts passes each oil sealing base through hole respectively, and is tightened in the corresponding housing for timing gear screw.Adopt such structure, in the bent axle rotation process, guarantee that the pressure that produces between bent axle and the oil sealing is even, moderate, thereby further improve sealing effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model embodiment's a sectional view.
Embodiment
As shown in drawings, crankshaft of diesel engine forward end seal device comprises the oil sealing base 4 that is connected in housing for timing gear 6, and described oil sealing base 4 is provided with a uncovered laterally annular groove; Be installed on the oil sealing 3 in the described groove, described oil sealing 3 is skeleton oil sealing.The sealing lip of described oil sealing 3 contacts with the outer circumferential face motive sealing of crankshaft flange 1, the inner peripheral surface static seal of the outer circumferential face of described oil sealing 3 and described groove; The inboard of described oil sealing base 4 be provided with one with the suitable locating flange 41 of described housing for timing gear 6, described locating flange 41 has same axis with described groove, described crankshaft flange 1 is fixed on the axle journal of bent axle 2.
Described oil sealing base 4 is connected for bolt with housing for timing gear 6.Described housing for timing gear 6 is provided with six edges circumferentially distribution and symmetrical in twos screw, described oil sealing base 4 is provided with and the suitable through hole of described screwhole position, the bar portion of six bolts 5 passes each oil sealing base through hole respectively, and is tightened in the corresponding housing for timing gear screw.
