Specific embodiment
The core of the utility model is to provide a kind of flotation device main axis protective sleeve, solves main shaft and easily consumes, repairs frequency
Numerous problem.
In order to make those skilled in the art more fully understand the utility model, with reference to the accompanying drawing and specifically
The utility model is described in further detail for embodiment.
Fig. 1 and Fig. 2 are please referred to, Fig. 1 is specific for the first of flotation device main axis protective sleeve provided by the utility model
The structural schematic diagram of embodiment；Fig. 2 is second of specific implementation of flotation device main axis protective sleeve provided by the utility model
The structural schematic diagram of example.
The utility model provides a kind of flotation device main axis protective sleeve, including protective case ontology 2, and protective case ontology 2 is circle
Tubular structure is equipped with round cavity, when processing protective case ontology 2, should ensure that the internal diameter of protective case ontology 2 slightly larger than main shaft
1 outer diameter, but gap should not be too large, that is, thus it can be prevented that between main shaft 1 and protective case ontology 2 there are lesser gap
Cause protective case ontology 2 and main shaft 1 that relative motion occurs because gap is excessive.
Main shaft 1 is installed through round cavity, that is, 1 length of main shaft is slightly longer than protective case ontology 2, after installation, main shaft 1
It is stretched out from protective case ontology 2, so, an annular gap is formed between main shaft 1 and protective case ontology 2, in order to anti-
Only ore pulp enter gap and corrode with wear spindle 1, sealing element 3 can be respectively set in two side end faces of protective case ontology 2, it is right
Gap between protective case ontology 2 and main shaft 1 is blocked, to improve the sealing performance of protective case entirety.
For considering for 2 insulating properties of protective case ontology and corrosion resistance is improved, protective case ontology 2 is preferably by oil resistant insulating
Rubber is made, the high resiliency, good insulating properties and the corrosion resistance that have using electro-insulating rubber, the advantages that surface is smooth, can be with
Acid ore pulp corrosion protection set ontology 2 is avoided, it is possible thereby to extend the service life of protective case ontology 2.
In a specific embodiment, above-mentioned sealing element 3 is specially epoxy resin adhesive layer, that is, not changing main shaft 1
In the case where material, one layer of epoxy resin sealing is respectively coated in two planar end surfaces of protective case ontology 2, it is solidifying to epoxy resin sealing
After Gu, that is, epoxy resin adhesive layer is formd, it, can since epoxy resin sealing has the advantages that good airproof performance, glue-joint strength are high
With gluing securely on main shaft 1 and protective case ontology 2, to realize to the jail between main shaft 1 and protective case ontology 2 at gap
Sealing is stifled, thus avoids acid ore pulp from entering in protective case ontology 2 and main shaft 1 is corroded and worn.Certainly, adhesive layer is not only
It is limited to epoxide resin material, can also is the other materials with corrosion resistance, about the specific colloidal materials of adhesive layer, originally
Text is not construed as limiting.
In another specific embodiment, above-mentioned sealing element 3 is specially nut cap, and the center of the nut cap offers circle
Through-hole after main shaft 1 is installed, nut cap is mounted in the round cavity of protective case ontology 2 so that main shaft 1 is pierced by from nut cap, is covered
The outer rim of cap is matched with the inner wall of protective case ontology 2.For considering for raising nut cap service life, it is preferred that nut cap uses
Oil resistant rubber is made, to improve the acid etch resistance energy of nut cap.
Above-mentioned nut cap can be cylindrical structure, or the polygonized structures such as regular hexagon, when nut cap is positive six sides
When shape structure, nut cap is acted on to tighten nut cap, that is, utilizing the opening knot at one end of spanner shank by spanner
Being screwed into and revolving for nut cap can be realized in use, threadingly direction of rotation to shank applies rotary force in structure, or set pore structure
It acts out；The circumferential surface of nut cap can be smooth curved surface, can also be equipped with non-slip texture, pass through the regular hexagon structure in nut cap
Lateral circle surface non-slip texture is set, to realize the purpose for increasing frictional force and pretightning force between spanner and nut cap.
In order to facilitate the installation and disassembly of nut cap, hanging ring 4 can be installed in the outer end face of nut cap, hanging ring 4 is with circle
The cyclic structure in section is soldered to the outer end face of the nut cap far from 2 one end of protective case ontology, is acted on and hung using auxiliary tool
Installation and disassembly to nut cap can be realized in ring 4, more province's time power.
Flotation device provided by the utility model is described in detail with main axis protective sleeve above.It is used herein
Specific case is expounded the principles of the present invention and embodiment, and the explanation of above example is only intended to help to manage
Solve the method and its core concept of the utility model.It should be pointed out that for those skilled in the art, not
Under the premise of being detached from the utility model principle, several improvements and modifications can be made to this utility model, these improve and repair
