Description
Technical field
The utility model is related to technical field of bearings, and in particular to a kind of bearing seal structure.
Background technology
Existing structure is made of following critical piece：1 dust guard, 2 bearing glands, 3 bearings, 4 bearing bodies, 5 axis, 6 labyrinths
Sealing ring.Dust guard 1 is sleeved on axis 5, and the inner circle of outer circle and bearing gland 2 cooperatively forms labyrinth seal ring 6, can will be extraneous
The impurity such as dust obstruct outside bearing bore.Bearing 3 and bearing gland 2 are fitted in bearing body 4, form bearing bore, chamber
Inside there is lubricating oil to be lubricated, cool down to the bearing 3 in work, labyrinth seal ring 6 also plays a part of preventing oil leakage.
Existing structure has the following disadvantages：Easily leakage, has certain interval, the splashing in bearing bore between labyrinth seal ring 6 and dust guard 1
Lubricating oil understand some pass through labyrinth seal ring 6, be leaked to outside, pollute working environment.
Utility model content
The utility model is in view of the above-mentioned problems, provide a kind of bearing seal structure.
The purpose of this utility model can be realized by following technical proposals：A kind of bearing seal structure, including bearing
Gland, bearing, bearing body, axis, labyrinth seal ring and gear oil jacket；The bearing body and gear oil jacket are set on axis, bearing
Gland is sleeved on gear oil jacket, and bearing gland combine and internal formation bearing bore with bearing body, bearing holder (housing, cover) be mounted on axis and
It is installed in bearing bore；One end of the gear oil jacket is located at outside bearing bore and screw and axis connection by being radially arranged are fixed,
Keep off oil jacket outer circle and bearing gland inner circle be engaged and between labyrinth seal ring is set, the other end for keeping off oil jacket is located at axis
Intracavitary is held, the other end outer circle for keeping off oil jacket forms cricoid oil retaining part to side extension and ends bent；The bearing gland
Composition bearing bore inner side end on form annular convex platform, annular convex platform correspond to the gear oil jacket other end outer circle and oil retaining part it
Between the space that is formed, the side of annular convex platform circumferentially offers annular groove.
Further, the outer circle of the gear oil jacket and/or the inner circle of bearing gland offer corresponding with labyrinth seal ring
Groove.
Further, further include dust guard, the dust guard is sleeved on gear oil jacket and outside bearing bore, dust guard
One end inner circle is embedded in the groove that one end outer circle for keeping off oil jacket opens up, and the other end of dust guard is against the outside of bearing gland
On end face.
Compared with prior art, the utility model has the advantage of：A part for lubricating oil is another by gear oil jacket in bearing bore
One end end face stops, directly flows back to bearing bore；A part of lubricating oil is guided by keeping off the oil retaining part that the oil jacket other end is formed to axis
Annular groove on pressure cap interior annular boss is flowed to inside bearing bore along annular groove, is not leaked again；Labyrinth seal ring
Prevent oil leak；The impurity such as the extraneous dust of dust guard barrier.The sealing of entire bearing arrangement and good dustproof effect.
Description of the drawings
Fig. 1 is the structural schematic diagram of the prior art.
Fig. 2 is the structural schematic diagram of the utility model.
It is marked in figure as follows：
1 dust guard, 2 bearing glands, 3 bearings, 4 bearing bodies, 5 axis, 6 labyrinth seal rings, 7 gear oil jackets, A oil retaining parts, B annulars
Slot.
Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing, those skilled in the art is made to become apparent from
How ground understanding puts into practice the utility model.Although describing the utility model in conjunction with its preferred embodiment, these
Embodiment only illustrates, rather than limits the scope of the utility model.
Referring to Fig. 2, a kind of bearing seal structure, including bearing gland 2, bearing 3, bearing body 4, axis 5, labyrinth seal ring 6
With gear oil jacket 7, the bearing body 4 and gear oil jacket 7 are set on axis 5, and bearing gland 2 is sleeved on gear oil jacket 7, and axis
Pressure cap 2 combines and internal formation bearing bore with bearing body 4, and bearing 3 is sleeved on axis 5 and is installed in bearing bore, bearing bore
Inside there is lubricating oil to be lubricated, cool down to the bearing 3 in work；One end of the gear oil jacket 7 is located at outside bearing bore and passes through diameter
Be connected and fixed to the screw of setting with axis 5, keep off oil jacket 7 outer circle and bearing gland 2 inner circle be engaged and between be arranged fan
The inner circle of palace sealing ring 6, the outer circle and/or bearing gland 2 of keeping off oil jacket 7 offers groove corresponding with labyrinth seal ring 6, keeps off
The other end of oil jacket 7 is located in bearing bore, and the other end outer circle for keeping off oil jacket 7 is formed cricoid to side extension and ends bent
Oil retaining part A；Annular convex platform is formed on the inner side end of the composition bearing bore of the bearing gland 2, annular convex platform corresponds to gear oil jacket 7
The space formed between the outer circle and oil retaining part A of the other end, the side of annular convex platform circumferentially offer annular groove B.
