Abstract
The utility model discloses a front oil seal seat of diesel engine, which comprises a front oil seal seat body, wherein the front oil seal seat body is provided with a center hole that is bonded tightly with the outer side of oil seal lip, the periphery of the front oil seal seat body is provided with a plurality of screw holes that are used to connect the body of the diesel engine, a convex solid is arranged at bottom end of the front oil seal seat body, the convex solid is provided with screw holes that are connected with the upper end of the oil bottom shell of the diesel engine, the front oil seal seat is matched with the crankshaft, the unit body and the oil bottom shell, so that the crankshaft machine-oil pump gear chamber and the front-end oil bottom shell form a closed space, so as to effectively seal the lubricating oil entering the crankshaft machine-oil pump gear chamber from the crankshaft, oil bottom shell and other parts, so that the front end of the crankshaft of the diesel engine reaches good sealing effect, thereby solving the problem of oil leakage and penetration of front end of the diesel engine and improving product quality.
Description
Technical field
The utility model relates to a kind of seal arrangement, relates in particular to a kind of seal arrangement of crankshaft of diesel engine front end.
Background technique
Now, most diesel oil machine front end is equipped with the crankshaft engine oil pump gear, and when diesel engine was worked, crankshaft engine oil pump gear chamber interior had a large amount of lubricant oil, made the leakage of oil of diesel engine front end, oil impregnate easily, influenced the quality of diesel engine integral body.
The model utility content
Technical problem to be solved in the utility model provides a kind of diesel engine Front oil seal seat that makes the crankshaft of diesel engine front end reach better sealing effect.
For solving the problems of the technologies described above, the technical solution of the utility model is: diesel engine Front oil seal seat, comprise the Front oil seal seat body, described Front oil seal seat body is provided with the center hole that can combine closely with the oil seal lip outside, described Front oil seal seat body periphery is provided with some screws that are connected usefulness with diesel-engine body, the bottom of described Front oil seal seat body is provided with outstanding entity, and described entity is provided with the connection screw that is connected usefulness with the diesel engine oil pan upper end.
As a kind of improvement, be provided with some radial pattern stiffening ribs around the described center hole.
Owing to adopted technique scheme, diesel engine Front oil seal seat, comprise the Front oil seal seat body, described Front oil seal seat body is provided with the center hole that can combine closely with the oil seal lip outside, described Front oil seal seat body periphery is provided with some screws that are connected usefulness with diesel-engine body, the bottom of described Front oil seal seat body is provided with outstanding entity, and described entity is provided with the connection screw that is connected usefulness with the diesel engine oil pan upper end; The Front oil seal seat cooperates with bent axle, body, oil sump, make crankshaft engine oil pump gear chamber and front end oil sump form the space of a sealing, can seal effectively from bent axle, oil sump and other parts and enter into the indoor lubricant oil of crankshaft engine oil pump gear, make the crankshaft of diesel engine front end reach good sealing effect, solve the difficult problem of diesel engine front end leakage of oil, oil impregnate, put forward the quality of high product.
Description of drawings
Accompanying drawing is the utility model embodiment's a structural representation.
Embodiment
As shown in drawings, diesel engine Front oil seal seat comprises the Front oil seal seat body, and described Front oil seal seat body is provided with the center hole 2 that can combine closely with the oil seal lip outside, be provided with some radial pattern stiffening ribs 3 around the described center hole 2, in order to strengthen the strength and stiffness of Front oil seal seat.Described Front oil seal seat body periphery is provided with some screws 4 that are connected usefulness with diesel-engine body, and the bottom of described Front oil seal seat body is provided with outstanding entity, and described entity is provided with the connection screw 5 that is connected usefulness with the diesel engine oil pan upper end.
Screw 4 links to each other with diesel-engine body by bolt, combines closely in Front oil seal lip and center hole 2 inboards, and Front oil seal is installed on the bent axle by interference fit; Present embodiment also can be used for sealing crankshaft engine oil pump gear chamber, plays the effect of front cover.Connect screw 5 and link to each other with oil sump, can play the effect of sealing front end oil sump, prevent that the interior lubricating oil splash of oil sump is to the body outside by bolt.
Present embodiment can constitute the cavity of sealing with body, framework and oil sump, can seal effectively from bent axle, oil sump and other parts and enter into the indoor lubricant oil of crankshaft engine oil pump gear, make the crankshaft of diesel engine front end reach good sealing effect, solve the difficult problem of diesel engine front end leakage of oil, oil impregnate, put forward the quality of high product.
