Abstract

The utility model discloses a novel interior outer lane all is arc toper profile raceway ball bearing, it is formed including arc toper profile inner circle, arc toper profile outer lane, holder and steel ball, steel ball are placed in between inner circle and the outer lane, and be fixed by the holder. Interior outer lane all is arc toper profile, and steel ball raceway is the arc conical surface promptly, four the arc toper wall surface contact in steel ball and interior outer lane, and arc vertex of a cone department forms a segment cavity with the steel ball, for oil storage area. Owing to interior outer ring raceway arc taper surface both sides inclination is different, the steel ball can rub by full surface contact when the raceway internal rotation, compares with the wearing and tearing orbit that the steel ball of traditional bearing was concentrated relatively, has reduced the probability that the steel ball lost efficacy owing to wearing and tearing greatly, and the two -point contact of steel ball and interior outer lane has increased the load scope of bearing, and in addition, oil storage area can store lubricating oil, help lubrication, reduce friction coefficient to extension steel ball life.

Description

A kind of novel Internal and external cycle is all arc tapered profiles raceway ball bearing
Technical field
This utility model relates to field of mechanical structure design, particularly relates to a kind of Novel ball field of bearings.
Background technology
Bearing is highly important a kind of parts in plant equipment in the present age, and its major function is to support machinery rotary body, reduces the coefficient of friction in its motor process, and ensures its rotating accuracy.For ball bearing, the effect rubbed between Internal and external cycle due to steel ball, it is easy to cause worn steel ball, although have grease can reduce the coefficient of friction of steel ball surface, but be generally also difficult to avoid that abrasion band wear out failure under long-term friction of Relatively centralized.Steel ball lost efficacy and caused bearing failure to remain an insoluble problem.
Utility model content
Deficiency for existing technology, the purpose of this utility model is: provide a kind of novel Internal and external cycle to be all arc tapered profiles raceway ball bearing, mainly from alleviating the angle of worn steel ball inefficacy to extend the life-span of bearing, to achieve these goals, this utility model provides following technical scheme: a kind of novel bearing, be asymmetric inner ring and outer ring including profile, steel ball ball and retainer, steel ball respectively with the arc tapered profiles sidewall contact of Internal and external cycle.It is characterized in that: in described outer ring, raceway is asymmetric arc taper cone pulley profile surface, be presented as that arc taper cone pulley profile surface both sides are unequal with the tangent line inclination alpha of steel ball contact point and β.
By technique scheme, arc tapered profiles is left-right asymmetry structure, and 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 full surface is in contact with it friction;
Novel being further arranged to of this use, steel ball and Internal and external cycle are all two-point contact.
By above technical scheme, steel ball and Internal and external cycle arc taper surface raceway two-point contact, not only can carry radial force, moreover it is possible to carrying axial force, improve bearing capacity.
Novel being further arranged to of this use, steel ball and arc tapered profiles two side contacts, have an areola with its top.
By using technique scheme, grease can be stored at steel ball in arc cone gap, help lubrication.
Compared with prior art, this use is novel to be provided the benefit that: achieve during bearing working face, whole world uniform contact between steel ball and raceway, wear out failure causes the problem of bearing failure because steel ball and raceway wear track are the most single to solve traditional bearing, extends the life-span of bearing;Steel ball and Internal and external cycle arc taper surface raceway 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 bearing another side.
Accompanying drawing illustrates, 1 is bearing outer ring, and 2 is steel ball, and 3 is retainer, and 4 is bearing inner race, and 5 is reserve.Here need to illustrate that Internal and external cycle arc tapered profiles and bearing centre are centrosymmetric figure.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
If Fig. 1 is this use new outer lane arc cone arcuate groove ball bearing schematic diagram, the micro-partial enlarged drawing of Fig. 2, it is made up of bearing outer ring 1, retainer 2, steel ball 3, bearing inner race 4,5 is reserve.
Described bearing internal external circle raceway is all asymmetric arc taper cone pulley profile surface, arc taper surface is unequal with the tangent line inclination alpha of steel ball contact point and β, due to this asymmetric contact, steel ball can realize surface complete with Internal and external cycle raceway under the effect of asymmetrical shearing force in being rolled into interior rolling process and contact, i.e. increase wear area, wear track is the most single, slow down the wear out failure of steel ball, thus extend the life-span of bearing, on the other hand, described steel ball 3 is two-point contact with described Internal and external cycle, increases its bearing capacity compared with traditional bearing.
Described reserve 5 is formed by steel ball and Internal and external cycle raceway contact gap, can store lubricating oil, in order to lubricate, reduces bearing steel ball and coefficient of friction of bearing internal external circle in rotation process.
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.
