As further program of the utility model：The upper end of the main shaft is assigned into seal, and lower end is sequentially interted
Go out bearing chamber, oil sealing, bearing and bearing baffle.
Compared with prior art, the utility model beneficial effect：
This sealing device, seal are arranged on above bearing chamber, form sealing for the first time and the sealing of most critical；Oil sealing
Inside bearing chamber, above bearing, form second and seal, so as to protect bearing not damaged by material, bearing chamber
The position for needing to seal is directly installed on, and seal supports the use, material cannot be introduced into bearing chamber, and the protection of shape matched bearings is made
With the utility model is simple in construction, easy to use, using gravity principle, plays permanent sealing function, reduces and change bearing
Number, extend bearing service life, so as to improve production efficiency, save labour, save resource.
Brief description of the drawings
Fig. 1 is structure sectional view of the present utility model.
In figure：1- main shafts；2- seals；3- bearing chambers；4- bolts；5- bearing baffles；6- oil sealings；7- bearings.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of sealing device, including main shaft 1, the upper end of main shaft 1 are provided with
Seal 2, for seal 2 to be a kind of using component made of cast iron or cast steel, the lower section of seal 2 is provided with bearing chamber 3, bearing
Room 3 uses component made of cast iron or cast steel to be a kind of, and seal 2 is arranged on above bearing chamber 3, and forming sealing for the first time is also
The sealing of most critical, bolt 4 is provided between seal 2 and bearing chamber 3, is connected to together by the spiral of bolt 4, bearing chamber 3
It is sleeved on main shaft 1, bearing chamber 3 is directly installed on the position for needing to seal, and seal 2 supports the use, and material cannot be introduced into
Bearing chamber 3, the protective effect of shape matched bearings 7 are provided with oil sealing 6 and bearing 7 in bearing chamber 3, oil sealing 6 for it is a kind of using steelframe and
Component made of rubber, oil sealing 6 are arranged on above bearing 7, and oil sealing 6 is arranged on inside bearing chamber 3, above bearing 7, is formed
