Description
Technical field
This utility model relates to the bearing oil-proof device in press technologies field, particularly to a kind of simple type mechanical type
Bearing oil-proof device.
Background technology
In forcing press industry, rolling bearing is commonly used, the life-span of rolling bearing be weigh mechanical stability against short circuit because of
One of element, and the lubrication of rolling bearing directly influences the life-span of rolling bearing.The lubrication of rolling bearing have grease lubrication and
Thin oil lubricant two kinds.Owing to grease lubrication lubricant effect is poor, and safeguard, maintenance inconvenience, actually used in less use.Dilute
Oil lubrication lubricant effect is preferable, and the constantly circulation of thin oil is prone to distributing of rolling bearing heat, simultaneously auto-supply, application maintenance
Relatively reliable, convenient, but thin oil lubricant easily produces oil leakage phenomenon, use process to bring unstable factor to client, thus greatly
Reduce greatly client's degree of recognition to forcing press production firm product.
Utility model content
This utility model is for the deficiencies in the prior art, it is provided that a kind of simple type mechanical type bearing oil-proof device, and ties
Structure is simple and reliable, reasonable in design, with low cost.
For this technical solution adopted in the utility model it is: this utility model includes being axially arranged with the bearing block (1) of cavity,
Being equipped with rotary shaft (7) in described bearing block (1) cavity, described rotary shaft (7) is provided with the axis of rolling being positioned at described cavity
Hold (2), described rotary shaft (7) be provided be positioned at described rolling bearing (2) both sides get rid of oil jacket (4), described in get rid of oil jacket at least
Within part is positioned at described cavity.
The described oil jacket (4) that gets rid of is provided with some prominent oil scraper rings getting rid of oil jacket (4) body being arranged circumferentially vertically.
The annular chamber of accommodating described oil scraper ring it is provided with in described bearing block (1).
Described getting rid of sets sealing ring (3) between oil jacket (4) and rotary shaft (7).
The oil jacket (4) that gets rid of of described side is positioned by the shaft shoulder of rotary shaft (7), and the oil jacket (4) that gets rid of of described opposite side passes through
It is positioned at this little round nut (5) getting rid of oil jacket (4) outside and stop washer (6) location.
The cross section of described oil scraper ring is triangular in shape.
Described annular chamber constantly reduces toward direction, both sides size from rolling bearing (2).
The oil jacket (4) that gets rid of of described every side arranges two annular chambers, wherein arranges one in the annular chamber of rolling bearing (2)
Individual oil scraper ring, arranges two oil scraper rings in the annular chamber away from rolling bearing (2).
Described rolling bearing (2) both sides are distributed with described sealing ring (3).
The utility model has the advantages that: this utility model bearing block is fixed with matrix by screw attachment, described rotary shaft
Being arranged on inside bearing block by rolling bearing, the both sides of rolling bearing fill respectively left and right gets rid of oil jacket, and oil jacket is got rid of by axle in the right side simultaneously
Shoulder location, a left side is got rid of and is screwed on little round nut and stop washer outside oil jacket；The left and right oil jacket that gets rid of also is prevented equipped with sealing ring with rotation between centers
Leak-stopping oil, therefore this utility model can realize the good lubrication to rolling bearing, but seal structure and can farthest ensure
Greasing do not produces the phenomenons such as leakage of oil, thereby ensure that the steady operation of forcing press；This utility model is simple and reliable for structure,
Reasonable in design, with low cost, can be applicable in the structure that rolling bearing is grease proofing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 bearing block, 2 rolling bearings, 3 sealing rings, 4 get rid of oil jacket, 5 little round nuts, 6 stop washers, 7 rotary shafts.
Detailed description of the invention
As it is shown in figure 1, bearing block 1 is connected and fixed with matrix by screw.Equipped with getting rid of oil jacket 4, rolling in rotary shaft 7
Bearing 2, and load onto stop washer 6 and little round nut 5 outside oil jacket 4 in getting rid of of side, last after in rotary shaft 7, each part installs
It is contained in inside bearing block 1.
This utility model is getting rid of between oil jacket 4 and rotary shaft 7 equipped with sealing ring 3, can play the effect of axial seal, anti-
Only thin oil is spilt by axial gap.When rotary shaft 7 rotates, thin oil rotates inside bearing block 1, and rolling bearing 2 is carried out immersion oil
Profit is changed.When rotary shaft 7 rotates, have thin oil respectively to the left side of rotary shaft 7, right side splash.If left and right sides protection is bad,
Leakage of oil will be produced.The getting rid of of both sides is equipped with on oil jacket 4 gets rid of oil structure, and three layers the most altogether, often through one layer, oil will be hindered
Every once, by the obstruct of three layers, thin oil will be completely blocked in bearing bore.The thin oil being deposited in bearing bore passes through again
Oil return pipe bottom bearing block 1 returns in the dilute oil lubrication station of lathe, thus forms a circulation closed.By thin oil not
Disconnected circulation, the heat of rolling bearing 2 is constantly cooled down by thin oil, and then promotes the service life of bearing, promotes client to life
Produce the degree of recognition of vendor product.
In forcing press industry, owing to when rotary shaft 7 rotates, linear velocity is relatively big, now rotating seal ring 3 notes when choosing
Selection has the sealing member of linear velocity big (general 10m/s).For improving rotating seal ring 3 sealing property in use,
This example have employed 45 steel, for improving surface smoothness and the hardness of rotating seal ring 3 contact site in rotary shaft further
Value, has carried out fine grinding and Quenching Treatment to it.
These are only preferably embodiment of the present utility model, also have other embodiment.All employing equivalents or
The technical scheme that equivalent transformation is formed, all should be in the protection domain that this utility model requires.
