Abstract
The utility model belongs to the technical field of machine elements, relates to a groove rolling hub cover, and aims to solve the problem that the service life of the existing groove rolling hub cover is influenced as the streamline bends toward the inner wall of the groove rolling hub cover, and grooves sunken on the inner wall are hard to avoid cutting off the streamline. The groove rolling hub cover disclosed by the utility model is provided with arc grooves on the inner wall, and the axial cross section thereof is distributed with the streamline which is consistent with the arc grooves in the bending direction. The above technical problem can be solved by the mentioned technical scheme.
Description
Technical field
The utility model belongs to the mechanical component technical field, relates to a kind of rolling ditch wheel hub overcoat.
Background technology
The fiber structure that metal forms in forging process is commonly referred to streamline; For the rolling ditch wheel hub overcoat that forms by metal forging; The concrete form of streamline can find out that streamline is the important indicator that the ditch wheel hub overcoat life-span is rolled in an influence from the shaft section of rolling over ditch wheel hub overcoat.
Roll over ditch wheel hub overcoat and be by processing after ditching is handled carrying out on the inwall of wheel hub overcoat; See Fig. 1, make the groove 4 of a depression of said inwall generation, because the streamline 3 general inwall directions of bearing ring are crooked; Therefore; When the wheel hub overcoat being carried out the ditching processing, can many streamlines 3 be blocked unavoidably, thus the service life of having reduced the stone roller ditch wheel hub overcoat of processing to a great extent.
The utility model content
The utility model technical matters to be solved is that the existing streamline that grinds in the ditch wheel hub overcoat is generally crooked to rolling over ditch wheel hub outer casing inner wall direction; And can streamline be blocked unavoidably to the groove that grinds ditch wheel hub outer casing inner wall depression; The service life of ditch wheel hub overcoat is ground in influence, and to this problem a kind of stone roller ditch wheel hub overcoat is provided.
The utility model solves the problems of the technologies described above through following technical scheme:
A kind of rolling ditch wheel hub overcoat, said rolling ditch wheel hub outer casing inner wall is provided with the arc raceway groove, it is characterized in that said rolling ditch wheel hub overcoat shaft section is distributed with and the consistent streamline of arc raceway groove bending direction.
After said structure is provided with; The profile of arc raceway groove is basic identical with the shape of streamline, and the arc channel profile is substantially parallel with streamline, can avoid the arc raceway groove to block the appearance of the situation of streamline as much as possible; Compared to the ruined stone roller ditch of streamline wheel hub overcoat, improve a lot service life.
Those skilled in the art can be easy to obtain above-mentioned streamline, for example roll over ditch technology with the cold rolling of conventional wheel hub overcoat and can obtain above-mentioned and the consistent streamline of arc raceway groove bending direction.
Further, the radius of said arc raceway groove is 5.65mm-6.65mm.
Description of drawings
Fig. 1 is the said a kind of wheel hub overcoat section drawing of not rolling over ditch of background technology;
Fig. 2 is the said a kind of section drawing of rolling over ditch wheel hub overcoat of embodiment.
The specific embodiment
Embodiment
See Fig. 2; A kind of rolling ditch wheel hub overcoat; Be provided with arc raceway groove 2, said rolling ditch wheel hub overcoat shaft section is distributed with the streamline 1 consistent with arc raceway groove 2 bending directions, and said streamline 1 can be manifested by conventional streamline process for show; For example can get wheel hub overcoat cross-sectional plane, polish then, polish, get final product with the picric acid corrosion.
The utility model is found according to long-term practice; If the radius of said arc raceway groove 2 is set to 5.65mm-6.65mm; Said streamline can not blocked by raceway groove; Thereby the life-span of rolling over the ditch bearing ring can obtain cooresponding raising, and for present embodiment, said arc lasso raceway groove 2 radiuses are 6.45mm.
More than show and described the advantage of groundwork, principal character and the utility model of the utility model.The technical personnel of the industry should be understood; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
