Abstract
The utility model discloses an angular contact ball bearing which comprises an outer ring, an inner ring and rolling balls, wherein the rolling balls are installed between the outer ring and the inner ring through a retaining frame, the inner ring is provided with a concave camber rolling way, and the range of an included angle formed by a connecting line of contact points between each rolling ball and the outer ring and the inner ring and the radial direction is 34 DEG to 43 DEG. The angular contact ball bearing can simultaneously bear radial force and axial force, the axis direction of a tapered roller is adjusted according to different use environments and according to different axial and radial bearing pressures, the axial and radial loading capacity is distributed most reasonably, the service life of the bearing is greatly prolonged, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of mechanical parts, particularly a kind of angular contact ball bearing.
Background technique
In the prior art; Bearing is divided into tapered roller bearing, roller bearing and ball bearing; Every kind of bearing has different functions when on equipment, using; As axial load resistant, anti-radial load or anti-axially and connected load radially or sliding friction changed into rolling friction; According to the required type of bearing and the size of size selected of different working environments, wherein ball bearing mainly bears radial load and rolling friction is changed in sliding friction, yet ball bearing but can not bear axial load; At this moment just need to adopt ball bearing to cooperate tapered roller bearing or roller bearing to use reaching the requirement of bearing axial load, yet so just make that input increases relatively.
The model utility content
To the deficiency that exists in the existing technology, the purpose of the utility model is to provide a kind of and can satisfies radial load and can satisfy long angular contact ball bearing of axial load and working life again.
The technological scheme of the utility model is achieved in that
Angular contact ball bearing; Comprise outer ring, inner ring and spin; Said spin is installed between said outer ring and the said inner ring through retainer, it is characterized in that, said inner ring has the concave arc surface raceway; The line of the point of contact of said spin and said outer ring and inner ring with radially form angle, the scope of said angle is 0 °-45 °.
Above-mentioned angular contact ball bearing, the line of the point of contact of said spin and said outer ring and inner ring is 34 °-43 ° with the angular range that radially forms.
Above-mentioned angular contact ball bearing has the pocket hole on the said retainer.
Above-mentioned angular contact ball bearing, the quantity in said pocket hole is identical with the quantity of said spin.
Above-mentioned angular contact ball bearing, the quantity of said spin are at least three.
Above-mentioned angular contact ball bearing, each said spin corresponding setting is in a pocket hole.
Above-mentioned angular contact ball bearing, the quantity of said spin are 23.
The beneficial effect of the utility model is: angular contact ball bearing is bearing radial force and axial force simultaneously; According to different Environmental Conditions; According to axially with the different axis directions of regulating tapered roller that radially bear pressure; The most reasonably distribution shaft to radially load-carrying ability, in the working life of having improved bearing greatly, reduced cost of production.
Description of drawings
Fig. 1 is the overall structure schematic representation of the utility model angular contact ball bearing,
Fig. 2 is the retainer subdivision structural representation of the utility model angular contact ball bearing,
Fig. 3 is the retainer structural representation of the utility model angular contact ball bearing.
Among the figure: 1-outer ring, 2-inner ring, 3-spin, 4-concave arc surface raceway, 5-retainer, 6-pocket hole.
Embodiment
In conjunction with accompanying drawing the utility model is done further explanation:
As shown in Figure 1; Angular contact ball bearing; Comprise outer ring 1, inner ring 2 and spin 3; Said spin 3 is installed between said outer ring 1 and the said inner ring 2 through retainer 5; Said inner ring 2 has concave arc surface raceway 4, and the line of the point of contact of said spin 3 and said outer ring 1 and inner ring 2 is 34 °-43 ° with the angular range that radially forms, and when spin 3 is in 34 °-43 ° scope with the line of the point of contact of inner ring 2 and outer ring 1 with the angular range that radially forms, can give full play to its axial load resistant ability; And the line that can also regulate spin 3 and the point of contact of inner ring 2 and outer ring 1 according to different applying working conditions and the angle of the angle that radially is thought of as change the distribution of radial and axial load-carrying ability; Make bearing when two bearing paired mounting, also can avoid causing additional axial force, and can axle is limited in the axial internal clearance scope at both direction the most perfectly to accomplish user demand.
Have pocket hole 6 on the said retainer 5; Said pocket hole 6 is 23; In each said pocket hole 6, lay a spin 3; Retainer 5 makes that through high-precision processing the distance between adjacent two pocket holes 6 all equates, makes spin 3 can stablize flexibly running in pocket hole 6 and the situation of spin displacement can not take place.
The foregoing description only be for clearly explain the utility model create done for example, and be not the qualification of the utility model being created embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all mode of executions.Any conspicuous variation of being extended out within all spirit and principles at the utility model or change still are in the utility model and create among the protection domain of claim.
