Description
Technical field
The utility model relates to field of bearings, particularly a kind of radial needle roller with two rib punching press inner ring and retainer assembly.
Background technique
Bearing is the important foundation component of all kinds of mechanized equipment, and its precision, performance, life and reliability play conclusive effect to the precision of main frame, performance, life and reliability.In engineering goods, bearing belongs to high-precision product, not only need the comprehensive support of the subjects such as mathematics, physics theory, and need materials science, heat treatment technology, precision machining and surveying, Numeric Control Technology and the effective subjects such as numerical method and powerful computer technology to serve for it, therefore bearing is again a product representing national science and technology strength.
What the inner ring radial needle roller of prior art and the inner ring of retainer assembly adopted is Vehicle Processing, and this processing mode not only low error of precision is large, and processing is inconvenient, and manufacturing efficiency is low.
Minimum wall thickness (MINI W.) >=the 2mm of the inner ring radial needle roller of prior art and the inner ring of retainer assembly, the space at shared use position is comparatively large and compare consume material, increases cost of material.
The roller end face of the bearing unit of the two rib inner ring of band of prior art contacts with inner ring rib, and this structure not only can not be carried out effectively spacing to bearing, and easily weares and teares, and maintaining cost increases.
Model utility content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, there is provided a kind of easy to process, working efficiency is high, saves and uses space, position, bearing is carried out effectively spacing, the radial needle roller of the two rib punching press inner ring of nonabradable band and retainer assembly.
The utility model solves the technological scheme that its technical problem adopts: a kind of radial needle roller with two rib punching press inner ring and retainer assembly, comprise inner ring, radial needle roller and retainer, described inner ring outer circumferential face two edges are equipped with the limited ring vertical with inner ring outer circumferential face, described radial needle roller is arranged between two limited rings, be equipped with retainer between described radial needle roller two ends and two limited rings, described retainer and radial needle roller against.
In order to increase the soundness of total, increase working life, described limited ring and inner ring one-body molded
Design.
Conveniently process, increase work efficiency, described limited ring and inner ring are integrated punch process and form.
In order to effectively save the space using position, described inner ring wall thickness < 1mm.
The beneficial effects of the utility model are: the radial needle roller of the two rib punching press inner ring of this band and retainer assembly are by adopting integrated punching processing, improve manufacturing efficiency, add the fastness of structure, by reducing the wall thickness of inner ring, effectively save the space using position, retainer is arranged between limited ring and radial needle roller, effectively carries out spacing to needle bearing, reduce friction, increase working life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the two radial needle roller of rib punching press inner ring of the utility model band and the structural representation of retainer assembly;
In figure: 1. inner ring, 2. radial needle roller, 3. retainer, 4. limited ring.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of radial needle roller with two rib punching press inner ring and retainer assembly, comprise inner ring 1, radial needle roller 2 and retainer 3, described inner ring 1 outer circumferential face two edges are equipped with the limited ring 4 vertical with inner ring 1 outer circumferential face, described radial needle roller 2 is arranged between two limited rings 4, be equipped with retainer 3 between described radial needle roller 2 two ends and two limited rings 4, described retainer 3 and radial needle roller 2 against.
In order to increase the soundness of total, increase working life, described limited ring 4 and inner ring 1 one
Molded design.
Conveniently process, increase work efficiency, described limited ring 4 and inner ring 1 be integrated punch process and
Become.
In order to effectively save the space using position, described inner ring 1 wall thickness < 1mm.
In fact, limited ring 4 is the rib of conventional bearings, is used for carrying out spacing to radial needle roller 2, and not only in this, simultaneously in bearing working process, limited ring 4 can also play the effect guiding retainer 3.
When inner ring 1 wall thickness reduces, by adjusting structurally, reduce the pressure of radial needle roller 2 pairs of inner rings, thus do not make integrally-built fastness reduce.
Compared with prior art, the radial needle roller of the two rib punching press inner ring of this band and retainer assembly are by adopting integrated punching processing, improve manufacturing efficiency, adding the fastness of structure, by reducing the wall thickness of inner ring 1, effectively saving the space using position, retainer 3 is arranged between limited ring 4 and radial needle roller 2, effectively carry out spacing to needle bearing, reduce friction, increase working life.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
