Description
Technical field
Vehicle component is the utility model is related to, especially a kind of circular ring shape axle-shaft oil seal being readily disassembled.
Background technology
Axle-shaft oil seal is the common part of automobile, is embedded in axle-shaft oil seal groove, by the drive axle and hub reduction of automobile
The lubricating oil of device is not connected at two positions.Axle-shaft oil seal is made by rubber more, the easy aging of rubber material, and is being used
During the inner ring of axle-shaft oil seal be affixed with semiaxis axial plane.It is easy in use for some time based on above-mentioned factor, axle-shaft oil seal
There is a situation where journal wear or material ageing go bad, axle-shaft oil seal is caused to lose sealability, it is therefore desirable to inspect periodically oil
Seal and replace in time the axle-shaft oil seal for losing sealability.Existing axle-shaft oil seal is mostly circular ring structure, for circular ring shape semiaxis
The replacement of oil sealing, it is general using between more sharp object insertion oil sealing and oil seal groove, oil sealing is prized, but this method is taking
Easily oil seal groove cell wall is damaged when going out oil sealing, causes to produce gap between oil seal groove and new oil sealing, influences new oil sealing
Sealing performance.
The content of the invention
Goal of the invention：In order to solve the above technical problems, the utility model proposes a kind of half shafting oil of circular ring shape being readily disassembled
Envelope, can avoid damaging oil seal groove cell wall when dismantling axle-shaft oil seal.
Technical solution：The utility model proposes technical solution be：
A kind of circular ring shape axle-shaft oil seal being readily disassembled, including：Oil sealing body 1, circular ring shape positioning plate 2 and at least one spiral shell
Mother 3；The oil sealing body 1 is annulus column, is adapted with corresponding axle-shaft oil seal groove；The circular ring shape positioning plate 2 covers
In oil sealing body 1 towards in the one side outside axle-shaft oil seal groove, the center of circle of circular ring shape positioning plate 2 falls in the central axes of oil sealing body 1
On；Circular shaft bore among the circular hole and oil sealing body 1 at 2 center of circular ring shape positioning plate is equal in magnitude, and circular ring shape positioning plate 2
Outside diameter is more than the outside diameter of 1 circular cylindrical cross-section of oil sealing body；The nut 3 is fixed on circular ring shape positioning plate 2 away from oil sealing body 1
One side on.
Further, dust plug is additionally provided with the screw hole of the nut 3, the dust plug is detachably connected with nut 3.
Further, the nut 3 is fixed on the circular ring shape positioning plate 2 and the misaligned anchor ring of oil sealing body 1.
Further, it is coated with hydrophobic oleophobic film in the one side of the circular ring shape positioning plate 2 away from oil sealing body 1.
Beneficial effect：Compared with existing oil sealing, the utility model has the advantage that：
The utility model mounting circular ring shape positioning plate on existing oil sealing body, and be provided with circular ring shape positioning plate
Nut；Only need to be screwed on fixation by a threaded rod to match with nut inner wall screw thread and nut in dismounting, then with screw thread
Bar is force lever, and axle-shaft oil seal is extracted out of oil seal groove, simple and convenient.During whole dismounting, threaded rod and oil
Sealing groove cell wall does not contact, therefore oil seal groove cell wall will not be damaged.
Brief description of the drawings
Fig. 1 is the front view of the embodiment of the utility model；
Fig. 2 is the top view of the embodiment of the utility model；
In figure：1st, oil sealing body, 2, circular ring shape positioning plate, 3, nut.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 to Fig. 2 show the structure chart of the present embodiment；In figure, including：Oil sealing body 1, circular ring shape positioning plate 2 and extremely
A few nut 3；The oil sealing body 1 is annulus column, is adapted with corresponding axle-shaft oil seal groove；The circular ring shape positioning
Plate 2 is covered in oil sealing body 1 towards in the one side outside axle-shaft oil seal groove, and the center of circle of circular ring shape positioning plate 2 falls in oil sealing body 1
On central axes；Circular shaft bore among the circular hole and oil sealing body 1 at 2 center of circular ring shape positioning plate is equal in magnitude, and circular ring shape is determined
The outside diameter of position plate 2 is more than the outside diameter of 1 circular cylindrical cross-section of oil sealing body；The nut 3 is fixed on circular ring shape positioning plate 2 away from oil
Seal in the one side of body 1.
In use, be screwed on fixation by a threaded rod to match with nut inner wall screw thread and nut, then with threaded rod
For the lever that exerts a force, axle-shaft oil seal is extracted out of oil seal groove.
In above-mentioned technical proposal, the point contact power between threaded rod and nut is converted to circular ring shape by circular ring shape positioning plate 2
Face contact force between positioning plate 2 and axle-shaft oil seal, since the area of circular ring shape positioning plate 2 is more than axle-shaft oil seal towards half shafting oil
The area of one side outside sealing groove, therefore can further increase the forced area of axle-shaft oil seal.
As the further optimization of above-mentioned technical proposal, dust plug, the dust plug are additionally provided with the screw hole of the nut 3
It is detachably connected with nut 3.Dust plug is used to avoid the screw hole of nut 3 to be blocked in use by greasy dirt and dust, influences
Dismounting.
Further, the nut 3 is fixed on the circular ring shape positioning plate 2 and the misaligned anchor ring of oil sealing body 1.
Nut 3 is arranged on 2 extension of circular ring shape positioning plate, increase 2 stress point of circular ring shape positioning plate and circular ring shape positioning plate 2 it is circular away from
From can be further laborsaving.
Further, hydrophobic oleophobic film is coated with the one side of the circular ring shape positioning plate 2 away from oil sealing body 1, it is hydrophobic to dredge
Oil film is used to avoid circular ring shape positioning plate 2 from being subject to greasy dirt to corrode, and causes the junction of itself and axle-shaft oil seal to be broken.
The utility model only needs to be screwed on by one and the threaded rod that nut inner wall screw thread matches and nut in dismounting
It is fixed, then using threaded rod as force lever, axle-shaft oil seal is extracted out of oil seal groove, it is simple and convenient.Whole dismounting process
In, threaded rod is not contacted with oil seal groove cell wall, therefore oil seal groove cell wall will not be damaged.
The above is only the preferred embodiment of the utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
