Abstract
The utility model provides a two -row ball bearing, belongs to bearing parts technical field, including outer lane, inner circle, steel ball, holder and sealing member, outside ring inner suiface, inner circle surface all are equipped with double annular channel, are equipped with the steel ball in the channel, are equipped with the holder in steel ball both sides, the holder has two, and every holder back is equipped with the open -ended fenestra, and the open -ended fenestra has from the hold depth, the caulking groove has been seted up to the inner circle inner wall, double annular channel both sides are located to the caulking groove branch, outer lane inner wall, inner embedding caulking groove are fixed in to the sealing member outer end to with the clearance setting of caulking groove outer wall. This two -row ball bearing adopts components of a whole that can function independently open type holder, has solved owing to inside space limitation the unable bottleneck that uses split type holder to the intensity of holder is greatly improved, and make and remain relative evenly distributed throughout between two steel balls, the equilibrium of load has improved, avoid stress concentration to bearing reliability and life -span is greatly improved.
Description
Technical field
This utility model belongs to bearing partss technical field and in particular to being a kind of two-row ball bearing.
Background technology
According to the difference of automobile model, on automobile engine idle pulley, some selection biserial deep groove ball bearings are as tensioner
Wheel bearing, the radial load that can bear for this bearing requires larger, typically can reach 1100N, therefore to this bearing
Design, in addition to high-quality raw material to be selected and technique, the sealing of bearing is particularly significant, deep-groove ball axle in prior art
It is provided with seal groove, sealing ring is embedded in described seal groove near the inner wall end surface of the outer ring held, but, the depth of this structure
Ditch ball bearing, after sealing ring embeds, sealing effectiveness is poor, is easy to produce leakage fat, and the service life of grease is difficult to meet and requires.
Utility model content
The purpose of this utility model is to overcome defect mentioned above and deficiency, and provides a kind of two-row ball bearing.
The technical scheme that this utility model realizes the employing of its purpose is as follows.
A kind of two-row ball bearing, including outer ring, inner ring, steel ball, retainer and sealing member；Described inner surface, inner ring
Outer surface is equipped with double annular channel, is provided with steel ball in raceway groove, is provided with retainer in steel ball both sides；Described retainer has two
Individual, each retainer back is provided with the fenestra of opening, and the fenestra of opening has from hold depth；Described inner ring inwall offers embedding
Groove；Described caulking groove is divided into double annular channel both sides；Outer ring inwall is fixed in described sealing member outer end, inner embedded caulking groove,
And arrange with caulking groove outer wall gap.
Described sealing member the inner is provided with first raised, the second raised and the 3rd projection；Described second projection is located at first
Raised and the 3rd projection is middle；The described first raised gap that there is 0.1 ~ 0.15mm with caulking groove outer wall；Described second raised with
There is the gap of 0.08 ~ 0.1mm in caulking groove outer wall；The described 3rd raised gap that there is 0.1 ~ 0.15mm with caulking groove outer wall.
This two-row ball bearing, using split open type retainer, is solved and is limited it is impossible to use split due to inner space
The bottleneck of formula retainer, and substantially increase the intensity of retainer；And make to remain relatively uniform between two row steel balls
Distribution, improves the equilibrium of load, it is to avoid stress concentration, keeps two row steel balls in rational distance work, thus greatly improving
Bearing reliability and life-span.In addition, this two-row ball bearing adopts sealing member, improve the sealing of bearing inner race, bearing outer ring
Degree and intensity are it is ensured that mechanical transmission mechanism effectively runs for a long time.
Brief description
Fig. 1 is cross section structure diagram of the present utility model；
Fig. 2 is to maintain the structural representation of frame；
Fig. 3 is the partial enlarged drawing in A portion in Fig. 1；
In figure：Outer ring 1, inner ring 2, caulking groove 2a, steel ball 3, retainer 4, the raised 5a of sealing member 5, first, the second raised 5b,
3rd raised 5c.
Specific embodiment
Below in conjunction with the accompanying drawings, this utility model is described in further detail.
A kind of two-row ball bearing, including outer ring 1, inner ring 2, steel ball 3, retainer 4 and sealing member 5；Table in described outer ring 1
Face, inner ring 2 outer surface are equipped with double annular channel, are provided with steel ball 3 in raceway groove, are provided with retainer 4 in steel ball 3 both sides；Institute
Stating retainer 4 has two, and each retainer 4 back is provided with the fenestra of opening, and the fenestra of opening has from hold depth；Described inner ring
2 inwalls offer caulking groove 2a；Described caulking groove 2a is divided into double annular channel both sides；Outer ring 1 is fixed in described sealing member 5 outer end
Inwall, inner embedded caulking groove 2a, and arrange with caulking groove 2a outer wall gap.
This two-row ball bearing, using split open type retainer, is solved and is limited it is impossible to use split due to inner space
The bottleneck of formula retainer, and substantially increase the intensity of retainer；And make to remain relatively uniform between two row steel balls
Distribution, improves the equilibrium of load, it is to avoid stress concentration, keeps two row steel balls in rational distance work, thus greatly improving
Bearing reliability and life-span.
Described sealing member 5 the inner is provided with the first raised 5a, the second raised 5b and the 3rd projection 5c；Described second raised 5b
In the middle of the first raised 5a and the 3rd projection 5c；Described first raised 5a and caulking groove 2a outer wall exist between 0.1 ~ 0.15mm
Gap；There is the gap of 0.08 ~ 0.1mm in the described second raised 5b and caulking groove 2a outer wall；Described 3rd raised 5c and caulking groove 2a outer wall
There is the gap of 0.1 ~ 0.15mm.
First raised 5a can store unnecessary oils and fatss in bearing, hinders oils and fatss excessive；Second raised 5b plays sealing and makees
With；3rd raised 5c prevents external dust from invading, and due to forming longer labyrinth seal passage, so that the sealing effectiveness of bearing is reached
Optimum degree.
Therefore, this bearing has good sealing property, and sealing member 5, to inner ring 2 no frictionally damage, is easily installed dismounting.
This utility model is illustrated according to embodiment, and on the premise of without departing from present principles, this device can also be made
Go out some deformation and improve.It should be pointed out that the technical scheme that the mode such as all employing equivalents or equivalent transformation is obtained, all fall
In protection domain of the present utility model.
