Description

Cold punching once-through bearing chamber bearing support

Technical field

The utility model belongs to field of mechanical technique, is specifically related to a kind of cold punching once-through bearing chamber bearing support.

Background technique

Bearing support is used comparatively extensive in mechanical field, is mostly the cast bearing seat at present, and the blank behind the very complicated casting of cast bearing seat production process also need pass through lathe, and repeatedly deep processing is just qualified, and manufacturing efficiency is low, has also increased cost of production simultaneously.Cast bearing seat fragility Da Yi fragmentation, the volume heaviness is used dumb and casting is generally used coalification iron, and the dust of Chan Shenging, harmful gas and noise etc. have caused the harm of environmental pollution and health in process of production.Existing ram axle bearing, only simplify production process and reduced cost, but lost the most basic robustness and the accuracy of bearing support, the working life of having reduced bearing and bearing support, in the small-sized basic machinery that can only be applied at a slow speed, precision is very low and load is lighter, utilization ratio is lower.The traditional bearing seat combines need and also bothers very much with bolt after boring, tapping with seal ring.

The model utility content

In order to overcome the above-mentioned defective that the known technology field exists; The purpose of this utility model provides the wider cold punching once-through bearing chamber bearing support of a kind of compared with prior art more reasonable Applicable scope, this bearing support not only in process of production environmentally safe health is not had injury, the protection environment; The operation that can have simultaneously the solidness of conventional cast bearing support and precision and existing ram axle bearing is simple, has reduced cost of production, has improved manufacturing efficiency, has saved the energy.And adopt the unique design scheme to have bearing chamber and sealing cover, and increased precision, the solidness of bearing support, prolonged bearing working life, the split-type structural of employing is flexible for installation, convenient, fast.

Cold punching once-through bearing chamber bearing support of the present utility model is made up of bearing support loam cake, base, bearing chamber, sealing cover, fixing bolt etc. by the following technical solutions.Described bearing chamber 4 adapts with bearing support cavity 11, is placed in the bearing support cavity 11 that bearing support loam cake 1 and base 2 surrounded; Described sealing cover 3 matches with bearing chamber 4, and closely buckles in bearing chamber 4; Described sealing cover 3 edges 13 adopt the groove of low structure between the senior middle school of both sides, make sealing cover 3 be easy to withhold closely in bearing chamber 4, but difficult drop-off; Described bearing support loam cake, base, fastening by clamping bolt 5 and nut 6 can make bearing support cavity 11 and bearing chamber 4 form Spielpassung; The degree of depth of the groove at described sealing cover edge 13 is the 0.2-0.3 millimeter; Sealing cover edge 13 adopts low structure between the senior middle school of both sides; Make sealing cover 3 withhold in original creation bearing chamber 4 difficult drop-off closely.Bearing chamber 4 is positioned over 11 li of the bearing support cavitys that bearing support loam cake 1 and base 2 surrounded closely, and described bearing chamber (4) can be placed bearing with sealing cover (3) center portion; Bearing support loam cake 1 and base 2 are provided with bolt hole; Can fix with the bolt hole of corresponding machinery.

Its beneficial effect of cold punching once-through bearing chamber bearing support that the utility model provides is that materials are in light weight less, robustness good, and solidness is raw-material 5-6 times; And the bearing chamber and the seal ring of design original creation, bearing chamber is the important accurate position that bearing support cooperates with bearing, traditional bearing seat and bearing chamber be connected need behind the casting of one lathe repeatedly precision machining form; The split type bearing chamber of this original creation adopts precise cold towards the drawing composite die once drawing and forming, real raising productivity guaranteed precision.The design of this seal ring is very perfect, is easy to put into need not in the bearing chamber also to be difficult for dropping out coming off with bolt; Solved that the traditional bearing seat need be holed with seal ring, tapping could ready-made the cooperation; The solidness that the stiffening rib at loam cake back has more been strengthened the solidness of bearing support and integral frame makes bearing support precision and solidness, stability, dustproof, convenient performance, settles at one go.

Embodiment

Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is described in further details.

With reference to Fig. 1 is the utility model cold punching once-through bearing chamber bearing support, and it comprises that compositions such as bearing support loam cake 1, base 2, sealing cover 3, bearing chamber 4, fixing bolt and above-mentioned part combine the stereogram of embodiment.By Fig. 1-3 as can be seen sealing cover 3 be held in the bearing chamber 4; The flange 9 that matches with the bearing support inner ring is arranged on the sealing cover 3; The flange 12 that matches with the bearing support inner ring is arranged on the bearing chamber 4; Bearing chamber 4 is positioned over 11 li of the bearing support cavitys that bearing support loam cake 1 and base 2 surrounded closely, and bearing is placed in bearing chamber 4 and the corresponding turning axle gauge hole of bearing inner race that sealing cover 3 central parts form; Bearing support loam cake 1 and base 2 are provided with

bolt hole

8 and 10; Can fix with the bolt hole of corresponding machinery.

When bearing is installed, earlier bearing is arrived bearing chamber 4 middle cover top cover labyrinths 3 down; Then the bearing chamber that has bearing is installed to 11 li of the bearing support cavitys that bearing support loam cake 1 and base 2 surrounded, bearing support is fixed on the position that to fix by bolt then, behind the clamping bolt, because the fastening effect of bolt makes the space of bearing support cavity 11 reduce to make bearing chamber 4 to be fastened on firmly in the bearing support cavity 11, from and can increase the steadiness of bearing, reduce because of bearing at work because of unstable unnecessary the beating that bring, prolonged the working life of bearing.

The utility model bearing chamber can match its mode of execution with the cast bearing seat for earlier bearing being placed into bearing chamber middle cover top cover labyrinth; Then the bearing chamber that has bearing is installed in the cast bearing seat cavity; bearing support is fixed on the position that to fix by bolt then; because the special manufacturing of bearing chamber and bearing cap; make 4 other forms of cooperations of cooperate degree of bearing support and bearing chamber; certainly the utility model bearing chamber bearing support that can cooperate is not limited only to above-mentioned bearing support, with its those skilled in the art that can adapt can expect all in protection domain.

As mentioned above, the utility model cold punching once-through bearing chamber bearing support is combined by bearing support loam cake 1, base 2, sealing cover 3, bearing chamber 4, fixing bolt etc. and is constituted, assembling has easily improved efficient between the each several part because reasonable in design makes, bearing also is installed to wherein easily, and because bearing chamber unique design, make its precision very high, the production method of cold-punching molding is that manufacturing efficiency improves, and has reduced cost.The combination of the sealing cover of original creation improves bearing support sealing level, has arrived good dustproof effect, has prolonged the working life of bearing simultaneously.

Although embodiment of the present utility model has been done detailed description above, but mode of execution of the present utility model is not limited to above-mentioned description, as long as can also make various variations to the utility model in the scope that does not break away from the utility model claim from the mode of execution that the utility model is expected to those skilled in the art.
