Description
Technical field
The utility model relates to a kind of double-row angular contact bal bearing, particularly the miniature double-row angular contact bal bearing of a kind of refrigerator.
Background technique
Single-groove grooved ball bearing, is the representational structure of most in rolling bearing, except bearing radial load, can also bears the axial load in two directions, of many uses.At present, single-groove grooved ball bearing product is generally adopted in general refrigeration agent, although single-groove grooved ball bearing is easy for installation, but use the refrigeration agent life-span of single-groove grooved ball bearing not long, vibration is comparatively large and create very large noise, because above reason can suppress the development of thermovision core devices, therefore improvement is carried out for the bearing used in refrigeration agent and be necessary.
Summary of the invention
The purpose of this utility model, the miniature double-row angular contact bal bearing of a kind of refrigerator is provided exactly in order to solve the problem, this double-row angular contact bal bearing not only can make bearing life increase and make the life-span of refrigerator elongated, and greatly reduces the vibration of bearing thus reduce the noise of refrigerator.
The purpose of this utility model is achieved in that
The miniature double-row angular contact bal bearing of a kind of refrigerator, comprising one is integral structure outer ring, an annular cushion block, two inner rings, two retainers and two row steel balls, the outer wall center of described outer ring is provided with a circular groove, and described often row steel ball is made up of 8 steel balls;
Described two inner rings are parallel to be arranged in described outer ring, and is provided with described annular cushion block between described two inner rings, and described two row steel balls are arranged between described inner ring and the raceway groove of outer ring by the described retainer that two be arranged in parallel uniformly;
Described retainer is arranged and described steel ball spherical packet hole one to one, described steel ball is placed in described spherical packet hole, described spherical packet hole and steel ball surface of contact are coated with wearing layer, the material of described wearing layer is high manganese steel, and the diameter of described spherical packet hole is 1.1-1.8 times of described steel ball size.
The above-mentioned miniature double-row angular contact bal bearing of a kind of refrigerator, wherein, even spread one deck fluorographite on the raceway groove of described inner ring and outer ring, described retainer adopts self-lubricating composite manufacture to form.
The above-mentioned miniature double-row angular contact bal bearing of a kind of refrigerator, wherein, the cross section of described self-lubricating composite comprises steel base layer, spherical bronze bisque, bronze wire spiral layers and modified polyacetal layer successively.
Compared with prior art, what the utility model was breakthrough has used miniature double-row angular contact bal bearing in refrigerator, and the life-span of this bearing is longer compared to existing technology and its vibration is very low; Meanwhile, an annular cushion block is set between two inner rings of this bearing, by this annular cushion block adjust outer ring, inner ring ditch position thus rotation flexibility and the rigidity of whole bearing can be adjusted.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, there is shown the miniature double-row angular contact bal bearing of a kind of refrigerator of the utility model, comprise one in 1, two, integral structure outer ring inner ring 2 and two row steel balls, the outer wall center of outer ring 1 is provided with a circular groove 3, and often row steel ball is made up of 8 steel balls 4.
The miniature double-row angular contact bal bearing of refrigerator also comprises an annular cushion block 5 and two retainers 6, two inner rings 2 walk abreast and are arranged in outer ring 1, and being provided with annular cushion block 5 between two inner rings 2, two row steel balls are arranged between the raceway groove of inner ring 2 and outer ring 1 by two retainers be arranged in parallel 6 uniformly; Even spread one deck fluorographite on the raceway groove of inner ring 2 and outer ring 1; Retainer 6 adopts self-lubricating composite manufacture to form, and the cross section of self-lubricating composite comprises steel base layer, spherical bronze bisque, bronze wire spiral layers and modified polyacetal layer successively.
Two retainers 6 are all arranged and steel ball 4 spherical packet hole 7 one to one, steel ball 4 is placed in spherical packet hole 7, spherical packet hole 7 and steel ball 4 surface of contact are coated with wearing layer, and the material of wearing layer is high manganese steel, and the diameter of spherical packet hole 7 is 1.5 times of steel ball 4 diameter.
Advantage for this model utility is as follows: due to spherical packet hole 7 and steel ball 4 surface of contact being coated with wearing layer, even spread one deck fluorographite on the raceway groove of inner ring 2 and outer ring 1 and retainer 6 adopts self-lubricating composite manufacture to form, so the wearing and tearing that bearing causes due to friction will reduce greatly, thus its life-span just improves.Meanwhile, an annular cushion block 5 is set between two inner rings 2 of this bearing, by this annular cushion block adjust outer ring 1, inner ring 2 ditch position thus rotation flexibility and the rigidity of whole bearing can be adjusted.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technological schemes also should belong to category of the present utility model, should be limited by each claim.
