Abstract
The utility model discloses a novel outer lane V -arrangement inner circle arc raceway ball bearing, it is constituteed including arc profile inner circle, V -arrangement profile outer lane, holder and steel ball. The steel ball is arranged in between inner circle and the outer lane, and is fixed by the holder, and inner circle arc profile cross -section is the bilateral symmetry structure, and there are one section level and smooth play and ball contact in the arc top, outer lane V -arrangement raceway is unsymmetrical structure, ball and V -arrangement both sides wall surface contact, and there is a sulculus at the V -arrangement top, for oil storage area, can store lubricating grease. The utility model discloses an asymmetrical V shape outer lane and steel ball contact, at first, the V -arrangement outer lane left and right sides is asymmetric, can make the steel ball ball can fully contact with the inner circle in the inside fully expand of bearing in the motion process, compares with conventional bearing steel ball to have increased area of contact to wearing and tearing alleviate, steel ball and V -arrangement outer lane two -point contact, because its inclination of both sides is different, the steel ball had both received the axial force also to receive the radial force, had increased bearing bearing capacity, in addition, oil storage area can store sufficient lubricating grease, and help is lubricated, reduces the coefficient of friction of steel ball friction motion.
Description
Technical field
This utility model relates to field of mechanical structure design, concretely relates to a kind of Novel ball bearing.
Background technology
Ball bearing is most important mechanical basic part, and its major function is to support machinery rotary body, reduces the coefficient of friction in its motor process, and ensures its rotating accuracy.
Bearing, as a kind of important drive disk assembly, is widely used in every field.Dividing by rolling element, bearing can be divided into ball bearing and roller bearing.For ball bearing, its main cause lost efficacy is that steel ball wear track in bearing internal external circle motor process is more concentrated, and the long-term abrasion concentrated causes steel ball to lose efficacy because of abrasion, and bearing often lost efficacy because steel ball lost efficacy.
Utility model content
For the deficiency of existing technology, this utility model purpose is to provide a kind of a kind of novel bearing reducing worn steel ball crash rate.
To achieve these goals, this utility model provides following technical scheme: a kind of new outer lane V-arrangement inner ring arcuate groove ball bearing, its composition includes bearing outer ring, reserve, retainer, steel ball rolling body and bearing inner race, and steel ball is placed between bearing internal external circle and is fixed by retainer.Pass through technique scheme, in described outer ring, raceway is asymmetric V-arrangement contoured surface, being presented as that V-arrangement contoured surface both sides inclination alpha and β are unequal, its two side contacts with steel ball, it is ensured that steel ball wear track when Internal and external cycle moves no longer is concentrated, but surface is in contact with it friction entirely, it addition, steel ball and Internal and external cycle arc taper surface raceway two-point contact, radial force not only can be carried, axial force can also be carried, improve bearing capacity.
Of the present utility model being further arranged to, steel ball contacts with V-arrangement profile two sides, has an intersegmental gap with its top notch.
By using technique scheme, grease can be stored in steel ball with slit space, help lubrication, reduce coefficient of friction.
Compared with prior art, the beneficial effects of the utility model are: the asymmetric two side of V-arrangement profile contact with steel ball can make steel ball in Internal and external cycle motor process surface contact friction complete with Internal and external cycle raceway and be no longer the wear track of Relatively centralized, thus increase contact surface, and then reduce steel ball because of the probability of wear out failure；Steel ball and V-arrangement face, outer ring two-point contact, not only can carry radial force, moreover it is possible to carrying axial force, improves bearing capacity；Additionally reserve can store lubricant grease, helps lubrication, reduces the coefficient of friction between steel ball and Internal and external cycle.
Accompanying drawing explanation
Fig. 1 is the structural representation of this novel bearing；
Fig. 2 is its partial enlarged drawing.
Fig. 3 is the partial enlarged drawing of this utility model another side.
Accompanying drawing illustrates, 1 is bearing outer ring, and 2 is reserve, and 3 is retainer, and 4 is steel ball, and 5 is bearing inner race.Here need outer ring V-arrangement profile and bearing axis figure axisymmetricly are described.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
If Fig. 1 is this utility model outer ring V-arrangement inner ring arcuate groove ball bearing structure schematic diagram, it is made up of bearing outer ring, retainer, steel ball rolling body, bearing inner race.
It is illustrated in figure 2 this utility model partial enlarged drawing, it is asymmetric V-arrangement contoured surface that described bearing outer ring and steel ball connect thick surface, V-arrangement face inclination alpha and β is unequal can make the steel ball ball can be fully deployed at Bearing inner in motor process, it is fully contacted with inner ring, contact area is increased compared with conventional bearings steel ball, thus slow down the probability that steel ball lost efficacy because of abrasion, improve the service life of bearing, steel ball rolling body is two-point contact with raceway in outer ring, steel ball is possible not only to carry radial force in motor process can also carry axial force, substantially increase the bearing capacity of bearing.Gap between bearing outer ring 1 and steel ball 4, as reserve, stores lubricating oil and can reduce coefficient of friction, also can slow down abrasion.
Above-described is only that the technical scheme under this utility model thinking belongs to this utility model protection domain and is not limited merely to above-described embodiment, and the technical scheme under all genus this utility model thinkings belongs to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
