Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
With reference to Fig. 1, a kind of agricultural equipment gear-box shaft combination oil seal, including shell 1 and inner casing portion 2, it is described outer
Shell portion 1 includes outer casing framework 11 and shell forming part 12, and shell is provided in the shell forming part 12 and seals main lip 13 and outer
Shell sealing pair lip 14, the shell seal main lip 13 by 15 banding of spring of annular；The inner casing portion 2 includes 21 He of inner casing skeleton
It is anti-to be provided with inner casing oil sealing pair lip 23, the main lip 24 of inner casing oil sealing and inner casing in the inner casing forming part 22 for inner casing forming part 22
Dirt lip 25；The shell seals that main lip 13 is corresponding with the position of inner casing oil sealing pair lip 23 and there are gaps between the two；Institute
It states the main lip 13 of shell sealing, shell sealing pair lip 14, inner casing oil sealing pair lip 23 and the main lip 24 of inner casing oil sealing and is respectively positioned on combination oil
On the internal spherical surface of envelope, the shell seals main lip 13, shell sealing pair lip 14, inner casing oil sealing pair lip 23 and inner casing oil sealing master
Lip 24 is in contact with shaft, for constraining shaft.
The shell seals main lip 13 and shell sealing pair lip 14 is used to be sealed the oil liquid in gear-box, is formed
First and second sealing, avoid oil liquid leakage.
The inner casing oil sealing pair lip 23 and the main lip 24 of inner casing oil sealing are used to the oil liquid in gear-box and are sealed, and form the
Three and the 4th sealing, avoids oil liquid leakage；The inner casing dustproof lip 25 be used to avoiding muddy water in adverse circumstances, weeds with
And dust etc. enters inside gear-box.
The outer casing framework 11 is fixedly connected with inner casing skeleton 21；The shell sealing pair lip 14 is located at shell and seals main lip
13 sides far from inner casing oil sealing pair lip 23.
It is obtuse angle that the shell sealing pair lip 14, which seals the angle of main lip 13 with shell,；The inner casing oil sealing pair lip 23 with it is interior
The angle of the main lip 24 of shell oil sealing and inner casing dustproof lip 25 and the main lip 24 of inner casing oil sealing is obtuse angle.
The shell sealing pair lip 14 seals between main lip 13 with shell, shell seals main lip 13 and inner casing oil sealing pair lip
Lithium saponify lubricating oil is filled in gap between 23 and between inner casing oil sealing pair lip 23 and the main lip 24 of inner casing oil sealing.
The inner casing dustproof lip 25 is particularly located at side of the main lip 24 of inner casing oil sealing far from inner casing oil sealing pair lip 23, and interior
The side that shell dustproof lip 25 is directed away from the main lip 24 of inner casing oil sealing is obliquely installed.
The working principle of the utility model are as follows: shell seal main lip 13, shell sealing pair lip 14, inner casing oil sealing pair lip 23 with
And the main lip 24 of inner casing oil sealing is in contact with shaft, occurs in the rotary course of shaft for constraining shaft, therefore can reduce
Circular runout, while four sealings can guarantee the leakproofness in the case where shaft is beated to oil liquid, avoid oil seal failure.
Oil liquid inside gear-box breaks through first of sealing of shell sealing pair lip 14 in the case where shaft is beated
Afterwards, the oil liquid inside gear-box reaches shell and seals at main lip 13, and under oil liquid pressure effect, shell seals main lip 13 and can send out
First portion deformation is in close contact with inner casing sealing pair lip 23, it is thus eliminated that shell seals main lip 13 and inner casing sealing pair lip 23
Between gap, cooperation lithium saponify lubricating oil pressure effect, to avoid oil liquid leakage.
The utility model is not confined to these for being further described to the utility model by above-described embodiment
Specific embodiment.Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc.,
It is interpreted as being within the protection scope of the utility model.
