Abstract
The utility model relates to a kind of crankshaft oil hole and cleans seal arrangement, comprise upper slips, lower slips, described lower slips is fastened on crankshaft journal, on upper slips and lower slips inner arc face, be respectively equipped with closed loop groove, in groove, be embedded with respectively seal ring and lower seal, upper seal ring contacts with crankshaft journal with lower seal and forms ring packing space.The inlet opening that when the utility model is used, cleaning solution is provided with by upper slips enters ring packing space, and then enters in the straight oilhole and inclined oil hole of air of bent axle, realizes the cleaning to crankshaft oil hole inside.Its good airproof performance, cleaning solution can be to upper slips and lower slips two side direction pressure releases.Have rational in infrastructurely, manufacture simply, good airproof performance, changes feature easily, is that a kind of desirable crankshaft oil hole cleans seal arrangement.
Description
Technical field
The utility model relates to crankshaft oil hole and cleans frock, and specifically a kind of crankshaft oil hole cleans seal arrangement.
Background technique
In prior art, crankshaft washer frock directly contacts with axle journal by upper and lower slips conventionally, and sealing is poor, thereby to two side direction pressure releases, causes crankshaft oil hole turbidity test not up to standard.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, manufactures simply, and good airproof performance, changes crankshaft oil hole easily and clean seal arrangement.
The technological scheme that the utility model solves its technical problem employing is: a kind of crankshaft oil hole cleans seal arrangement, comprise upper slips, lower slips, described upper slips, lower slips are fastened on crankshaft journal, it is characterized in that: on described upper slips and lower slips inner arc face, be respectively equipped with closed loop groove, in groove, be embedded with respectively seal ring and lower seal, upper seal ring contacts with crankshaft journal with lower seal and forms ring packing space.
Described upper seal ring and lower seal are closed loop seal ring, are embedded in respectively in the closed loop groove of upper slips and lower slips.
The utility model is distinguished seal ring and lower seal on setting-in in upper slips and lower slips groove, they contact with crankshaft journal and form ring packing space, the inlet opening that cleaning solution is provided with by upper slips enters ring packing space, and then enter in the straight oilhole and inclined oil hole of air of bent axle, realize the cleaning to crankshaft oil hole inside.Against existing technologies, the utility model good airproof performance, cleaning solution can be to upper slips and lower slips two side direction pressure releases.It has rational in infrastructure, manufactures simply, and good airproof performance, changes feature easily.That a kind of desirable crankshaft oil hole cleans seal arrangement.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is composition structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to schematic diagram.
1. upper slipses in figure, 2. crankshaft journal, 3. goes up seal ring, 4. ring packing space, 5. lower seal, 6. lower slips.
Embodiment
From Fig. 1, Fig. 2, can find out, a kind of crankshaft oil hole cleans seal arrangement, comprise upper slips 1, lower slips 6, described upper slips 1, lower slips 6 are fastened on crankshaft journal 2, it is characterized in that: on described upper slips 1 and lower slips 6 inner arc faces, be respectively equipped with closed loop groove, in groove, be embedded with respectively seal ring 3 and lower seal 5, upper seal ring 3 contacts with crankshaft journal with lower seal 5 and forms ring packing space 4.
Described upper seal ring 3 and lower seal 5 are closed loop seal ring, are embedded in respectively in the closed loop groove of upper slips and lower slips.
When the utility model is used, the inlet opening that cleaning solution is provided with by upper slips 1 enters ring packing space 4, and then enters in the straight oilhole 21 and inclined oil hole of air 22 of bent axle, and enters other oilhole from inclined oil hole of air, completes the cleaning of crankshaft oil hole inside.
The utility model good airproof performance, cleaning solution can be to upper slips and lower slips two side direction pressure releases.It has rational in infrastructure, manufactures simply, and good airproof performance, changes feature easily.That a kind of desirable crankshaft oil hole cleans seal arrangement.
