Background technology
Deep groove ball bearing is a type the most common in rolling bearing.The deep groove ball bearing of basic model is outer by one
Circle, an inner ring, one group of steel ball and one group of retainer are constituted.Deep groove ball bearing type has single-row and two kinds of biserial, zanjon chou
Structure is also divided to sealing and two kinds of structures of open type, and open type refers to bearing without sealing structure, closed type deep-groove ball be divided into dust seal and
Anti- oil seal.Dust seal cover material is steel plate punched, only serves and simply prevent dust and enter raceway.Oilproof is to connect
Touch oil sealing, can effectively prevent the grease in bearing excessive.
At present, the Chinese patent of Application No. CN200920112625.1 discloses a kind of sealing knot of deep groove ball bearing
Structure, including bearing inner race, bearing outer ring and at least one lip ring, described sealing member is located at outside bearing inner race and bearing
Between circle, bearing outer ring inner side is provided with the annular dustproof groove one corresponding with sealing member, and the outer rim of above-mentioned sealing member is embedded into
In bearing outer ring dustproof groove one, the inner edge of the sealing member has seal lip one, seal lip two, seal lip three and sealing
Lip four.
Although the sealing structure good sealing effect of this deep groove ball bearing, simple structure, closure assembling is fixed up
It is brought into close contact with rotating shaft outer ring and rotating shaft inner peripheral surface afterwards, and is not easy to disassemble.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of deep-groove ball axle of convenient dismounting
Hold.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of deep groove ball bearing,
Including bearing outer ring, bearing inner race and closure, retainer is provided between the bearing outer ring and bearing inner race, outside the bearing
The medial wall of circle is provided with the turnover groove for closure radial rotary, and the turnover groove includes head end and tail end, the head
End bending extends protruding shaft, between the protruding shaft and turnover groove through the side of bearing outer ring on the side of the closure
Enter line slip cooperation.
By above-mentioned technical proposal, when the space between sealed bearings outer ring and bearing inner race is wanted, by closure side
On protruding shaft from turnover groove head end send into turnover groove in, protruding shaft by be slid onto up to turnover groove the other end, and then
Whole closure is covered between bearing outer ring and bearing inner race, play sealing function；When to dismantle closure, reversely rotate
Closure, making protruding shaft move to head end can just take out closure, make the easy to loading and unloading of closure and do not result in damage.
Preferably, the tail end is bent towards retainer direction.
By above-mentioned technical proposal, if tail end is not bent, closure only needs to that protruding shaft is aligned the end of turnover groove
Mouthful one presses, then is rotated and just can complete fixation, but deep groove ball bearing can drive when rotated closure to rotate, at this moment protruding shaft meeting
Head end is moved to, is simply fallen out, tail end is bent towards retainer direction now, the protruding shaft on closure is finally stuck in tail
On end, prevent closure from being rotated, make closure be not easy to drop out.
Preferably, the protruding shaft is the square shaft being engaged with the medial wall of turnover groove.
By above-mentioned technical proposal, due to being attached by protruding shaft and turnover groove between closure and bearing outer ring,
After closure is fixed, protruding shaft can be rotated in turnover groove causes closure to deflect, and makes closure inner side and retainer
Contact, hinders the operating of deep groove ball bearing, and square protruding shaft can prevent closure from deflecting, it is to avoid closure hinders zanjon
The operating of ball bearing.
Preferably, the medial wall of the turnover groove tail end is provided with the Anti-skid sheet on the protruding shaft surface that can fit.
By above-mentioned technical proposal, protruding shaft is slided into behind turnover groove one end end, and closure is fixed on bearing outer ring, convex
Axle can also enter to a certain extent line slip, and after protruding shaft is contacted with the Anti-skid sheet being located on turnover groove ends medial wall, two
There is larger friction between person, and then make that protruding shaft is viscid no longer to slide on Anti-skid sheet, the position of further fixing seal lid.
Preferably, the head end and the flexible shield of the junction of bearing outer ring side covering, the one of the elastic shield
Side is fixedly connected on the medial wall of head end and is passed through for protruding shaft with being curved.
By above-mentioned technical proposal, after closure is covered on bearing outer ring, the head end of bearing groove is in communication with the outside, extraneous
Impurity can be deposited in turnover groove, hinder the normal turnover of protruding shaft, now on this junction covers after elastic shield,
When protruding shaft presses to elastic shield, elastic shield can produce certain bending passes through protruding shaft, and after passing through etc. protruding shaft, elastic shield is extensive
Restore shape to prevent impurity from causing blocking into turnover groove.
Preferably, the protruding shaft quantity is two, and is symmetrically distributed in both sides on closure, has two on the bearing outer ring
The individual turnover groove corresponding with protruding shaft.
By above-mentioned technical proposal, after two symmetrical protruding shafts are inserted respectively in corresponding turnover groove, can make
Closure will not rock after fixing, and make closure more stable.
Preferably, the outer surface of the closure is provided with the gripping groove for accommodating finger.
By above-mentioned technical proposal, when closure is taken out, the surface of closure smooths, without impetus so that close
Capping is not allowed to be drawn out easily, and the gripping groove being located on sealing exterior surface can provide an impetus, make closure easily quilt
Extract.
Preferably, the medial wall for gripping groove is provided with tread plate.
By above-mentioned technical proposal, when to dismantle closure, put his hand into and pull out in gripping groove closure, but grip
Groove medial wall is relatively smooth, causes handss and the friction that grips between groove less, is difficult stress, and tread plate can increase handss with
The friction between groove is gripped, closure just can be pulled with less power, requirement of the dismounting closure to power is reduced.
