Abstract
The invention discloses a novel ball bearing with an inner ring and an outer ring being arc-and-cone-shaped contour rolling tracks. The ball bearing comprises the arc-and-cone-shaped contour inner ring, the arc-and-cone-shaped contour outer ring, a retainer and a steel rolling ball, and the steel rolling ball is arranged between the inner ring and the outer ring and fixed by the retainer. The inner ring and the outer ring are both of arc-and-cone-shaped contours, in other words, the steel ball rolling track is an arc-and-cone-shaped surface, the steel ball is in contact with four arc-shaped wall faces of the inner ring and the outer ring, and a small gap section is formed between the arc top and the steel ball and serves as an oil storage area. The inclination angles of the two sides of the arc-and-cone-shaped surfaces of the rolling tracks of the inner ring and the outer ring are different, the steel ball revolves around the center of the bearing in the rolling track, meanwhile, the steel ball can be overturned to be completely unfolded, the abrasion tracks formed when the steel ball moves on the inner ring and the outer ring are not centralized any more, in other words, the abrasion contact surface between the steel ball and the bearing is increased, under the circumstance that other conditions are the same, compared with traditional bearings, abrasion is alleviated, the service life of the steel ball is prolonged, and furthermore, the service life of the bearing is prolonged.
Description
Technical field
The present invention relates to field of mechanical structure design, particularly relate to the design of 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. For ball bearing, due to the effect that steel ball rubs between Internal and external cycle, easily cause worn steel ball, although have grease can reduce the coefficient of friction of steel ball surface, but be generally also the rubstrip being difficult to avoid that Relatively centralized wear out failure under long-term friction.
By the known a kind of Multi-contact ball bearing of CN104956105A, its multiple spot performance guarantees bottom the rolling surface of ball under acting on big radial load effect with inner race track and also can prevent the damage of rolling surface of ball when part contact near it, but cannot be avoided steel ball in rotation process contact wear track concentration and affect the durability of steel ball.
By the known angular contact ball bearing of a kind of grease lubrication of CN105209773A, though the lubrication considered in steel ball motor process that this invention is careful, it is not solved by the problem that steel ball causes steel ball to lose efficacy with Internal and external cycle contact wear face Relatively centralized.
Summary of the invention
Deficiency for existing technology, it is an object of the invention to: provide a kind of novel Internal and external cycle to be all arc tapered profiles raceway ball bearing, main from alleviating angle that worn steel ball lost efficacy to extend the life-span of bearing, to achieve these goals, the technical scheme is that 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, being 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, steel ball and Internal and external cycle raceway are all two-point contact.
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; 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.
The further setting of the present invention is, steel ball contacts with arc tapered profiles two sides, has an areola with its top.
By adopting technique scheme, it is possible to storage grease in steel ball with arc cone gap, help lubrication.
Compared with prior art, the invention has the beneficial effects as follows: achieve in bearing working process 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 excessively 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 opposite side partial enlarged drawing of the present invention.
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 accompanying drawing 1 to 3, the present invention is further described.
If Fig. 1 is outer ring of the present invention 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 contacting with the full surface of Internal and external cycle raceway in being rolled into interior rolling process under the effect of asymmetrical shearing force, namely wear area is increased, wear track is no longer single, slow down the wear out failure of steel ball, thus extending 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, it is possible to store lubricating oil, in order to lubricate, reduces bearing coefficient of friction of steel ball and bearing internal external circle in rotation process.
Above-described is only that technical scheme under thinking of the present invention belongs to scope and is not limited merely to above-described embodiment, and the technical scheme under all genus thinking of the present invention belongs to protection scope of the present invention. It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under inventive principle premise, these improvements and modifications also should be regarded as protection scope of the present invention.
