Abstract
The utility model discloses a groove type star-shaped rotor. A groove is formed at a 1/4 part of an internal spherical surface of the star-shaped rotor. The structure is simple and ingenious, and a lubricating effect between the star-shaped rotor and an internal spherical surface of a retainer is greatly improved, so that wear of the star-shaped rotor is reduced, and the service life of the star-shaped rotor is greatly prolonged; and meanwhile, the star-shaped rotor is easy and convenient to produce and manufacture, which is good for the long-term development and widens the application range.
Description
Technical field
The utility model relates to a kind of groove type star rotor.
Background technique
Star rotor of the prior art, structure arranges Shortcomings, its outer spherical surface in constant velocity universal joint with the contact friction of retainer inner ball surface, in the working life of greatly reducing star rotor, be unfavorable for long-run development.Such star rotor also could satisfy the demand of existing market, haves much room for improvement!
Addressing these problems is extremely urgent as from the foregoing!
In view of this, the inventor has done deep research to this, designs a kind of groove type star rotor, exquisiteness simple in structure, greatly strengthen the lubrication effect of star rotor and retainer inner ball surface, thereby reduce the wearing and tearing of star rotor, and increase substantially the working life of star rotor, simultaneously, on manufacturing, simple and convenient, be beneficial to long-run development, also enlarge simultaneously using scope, this case produces thus.
The model utility content
The purpose of this utility model is for a kind of groove type star rotor is provided, exquisiteness simple in structure, greatly strengthen the lubrication effect of star rotor and retainer inner ball surface, thereby reduce the wearing and tearing of star rotor, and increase substantially the working life of star rotor, simultaneously, on manufacturing, simple and convenient, be beneficial to long-run development, also enlarge simultaneously using scope.
For achieving the above object, the technical solution of the utility model is:
The groove type star rotor, its characteristics are: 1/4 place is provided with a groove at the star rotor outer spherical surface.
Further, the oral area width of described groove is less than the width of bottom.
Further, the width of described groove is at 0.15-0.2mm.
Further, the width of described groove is at 0.15mm.
Further, the width of described groove is at 0.2mm.
Further, the degree of depth of described groove is at 0.2-0.5mm.
Further, the degree of depth of described groove is at 0.2mm.
Further, the degree of depth of described groove is at 0.5mm.
The beneficial effects of the utility model: the structure setting that the utility model is such, in actual use, can be when retainer contacts with star rotor, storage butter in the outer channel, greatly strengthen the lubrication effect of retainer and star rotor, thereby increase substantially the working life of retainer and star rotor.
In addition, the oral area width of groove can delay the time that the butter in the groove exosmose like this less than the width of bottom, prolongs whole working life.
Simultaneously, the utility model is on manufacturing, and is simple and convenient, is beneficial to long-run development, also enlarges simultaneously using scope.
As from the foregoing, the utility model exquisiteness simple in structure, greatly strengthen the lubrication effect of star rotor and retainer inner ball surface, thereby reduce the wearing and tearing of star rotor, and increase substantially the working life of star rotor, simultaneously, on manufacturing, simple and convenient, be beneficial to long-run development, also enlarge simultaneously using scope.
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to the accompanying drawings 1, present embodiment discloses a kind of groove type star rotor, and its characteristics are: 1/4 place is provided with a groove 2 at star rotor 1 outer spherical surface.
Further arrange, the oral area width of described groove 2 is less than the width of bottom.
Wherein, the width of described groove 2 is at 0.15-0.2mm, and the width of described groove 2 is preferably 0.15mm or 0.2mm.
The degree of depth of described groove 2 is at 0.2-0.5mm, and the preferred depth of described groove 2 is at 0.2mm or 0.5mm.
Such structure setting, in actual use, can be when retainer contacts with star rotor, the storage butter are greatly strengthened the lubrication effect of retainer and star rotor, thereby are increased substantially the working life of retainer and star rotor in the outer channel.Simultaneously, simple and convenient on manufacturing, be beneficial to long-run development, also enlarge simultaneously using scope.
As from the foregoing, the utility model exquisiteness simple in structure, greatly strengthen the lubrication effect of star rotor and retainer inner ball surface, thereby reduce the wearing and tearing of star rotor, and increase substantially the working life of star rotor, simultaneously, on manufacturing, simple and convenient, be beneficial to long-run development, also enlarge simultaneously using scope.
The above only is an embodiment of the present utility model, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
