Abstract
The utility model is related to a kind of sealing structure of deep groove ball bearing, it offers a circle seal groove I in the both sides of bearing outer ring inner surface respectively, a circle seal groove II is offered respectively in the both sides of bearing inner race outer surface, seal groove I and seal groove II stagger setting and seal groove I is located at the inner side of seal groove II, seal groove I is inwardly angled to be opened up, seal groove II tilts opens outward and set and between the open outer side of seal groove II and bearing inner race outer face provided with guide surface of the ring cross-section as arc, the inner groove surface arc transition of the guide surface and seal groove II；It is additionally provided with sealing ring, the interior edge of soft quality sealing that sealing ring has the soft quality that can be embedded in seal groove I sealing outer and can be embedded in seal groove II.The problem of the utility model efficiently solves the sealing ring dismounting inconvenience existed under traditional deep groove ball bearing sealing structure.
Description
Technical field
The utility model is related to technical field of bearings, and in particular to a kind of sealing structure of deep groove ball bearing.
Background technology
The both sides of the inside and outside circle of bearing can effectively prevent Bearing inner lubricant from leaking outside and external dust by sealing ring sealing
Into Bearing inner.
The loss of internal lubricant occurs in bearing after work certain time, and this is accomplished by periodically pulling down sealing ring to mend
Fill lubricant.And under existing bearing seal structure, the problem of generally existing sealing ring dismounting inconvenience is mainly shown as：Tear open
There is no the good point of application when unloading, on sealing ring, layman can produce the sensation had no way of handling；During installation, sealing ring
Outer can not be fortunately sticked into the seal groove of the inside and outside circle of bearing, and this easily sealing ring occurs in bearing follow-up operation and come off
Situation, its gently then cause lubricant be lost in, dust enter bearing internal external circle between influence bearing service life, it is heavy then presence come off
Sealing ring influence the normal work of other transmission systems.
The content of the invention
The utility model is solves the problem of sealing ring that traditional deep groove ball bearing is present dismounts inconvenience, and spy provides one kind
The sealing structure of deep groove ball bearing.
The utility model is achieved by the following technical solution：
A kind of sealing structure of deep groove ball bearing, it offers a circle seal groove in the both sides of bearing outer ring inner surface respectively
I, a circle seal groove II is offered respectively in the both sides of bearing inner race outer surface, is characterized in that:Seal groove I and seal groove II
Stagger setting and seal groove I be located at seal groove II inner side, seal groove I is inwardly angled to be opened up, seal groove II tilt opens outward set
And between the open outer side of seal groove II and bearing inner race outer face provided with a ring cross-section be arc guide surface, the guide surface with
The inner groove surface arc transition of seal groove II；Sealing ring is additionally provided with, sealing ring has the soft quality sealing outer that can be embedded in seal groove I
With edge in the soft quality sealing that can be embedded in seal groove II.
Such scheme solves the problem of sealing ring installs inconvenience, during installation, first can be stuck in the sealing outer of sealing ring
In seal groove I（The incline direction of seal groove I facilitates being caught in for sealing outer）, the then slow sealing exerted a force by pressure seal ring
Along finally seal groove II is caught under the guide effect of guide surface in interior edge, sealing, the installation of sealing ring is realized.
Preferably to solve the problems, such as the dismounting of sealing ring, the utility model has following more excellent scheme：
Fluting is respectively equipped with two end faces of bearing outer ring；Sealing ring has hard annular brace matrix, annular brace base
Body is integrally formed by the annular ring in outside and the introversion annular brace circle of inner side；Edge and sealing outer difference in the sealing of sealing ring
Coat the inside and outside edge of introversion annular brace circle and extend；Sealing ring is additionally provided with the sealing outer II of laminating fluting, the ring of sealing ring
The opening groove for being easy to open is formed between shape circle outer and sealing outer II.
In such scheme, when dismantling sealing ring, a crow bar can be chosen（Or the instrument such as flat mouth screwdriver）, by the point of crow bar
End in insertion opening groove, then outwards exerts a force above opening groove（The annular ring of hard can ensure that the force for bearing crow bar）, just
Easily the sealing outer of sealing ring can be prized, sealing outer just can easily remove sealing ring after prizing.In addition, outside above-mentioned sealing
Effectively it can prevent external dust from entering Bearing inner along II setting.
The beneficial effects of the utility model are：It efficiently solves traditional deep-groove ball axle by rational structure design
The problem of holding the sealing ring dismounting inconvenience existed under sealing structure.
