Abstract
The utility model relates to a bearing retainer with the function of storing grease lubricant, which includes steel balls (1) and a keeper (2); the steel balls (1) are arranged in the keeper (2); the keeper (2) is a sphericity; and a section of ring (3) is arranged at left and right symmetric positions inside the sphericity. The utility model has the advantages that the lubricating condition of the bearing can be improved and the service life of the bearing can be prolonged because certain grease lubricant is arranged in a ball bag of the retainer. Experiments show that the service life of the whole bearing can be prolonged by 30-50%, and the life of quality assurance can be prolonged to three years from two years.
Description
Technical field
The utility model relates to a kind of bearing, relates in particular to the retainer of this bearing.
Background technique
The retainer function of bearing is that rolling element is partly surrounded, and makes it keep certain interval at circumferencial direction, can be divided into pressing cage, car system retainer, shaping retainer and pin formula retainer by the technology difference; And can be divided into steel retainer, copper cage, nylon cages and phenolic resin retainer according to the difference of material.
The form nylon cages has long low noise of life-span, easily processing, cost is low, manufacturing efficiency is high owing to become, and the characteristics that the use field is wide are used more and more widely.
Lubricating system commonly used is divided into oil lubrication and grease lubrication.
Fig. 1 is the schematic representation that grease lubrication becomes the form nylon cages in the prior art, because shape and steel ball basically identical in the ball pocket, when steel ball rotates in retainer, lubricating grease in the ball pocket is difficult to maintain, because the real effective lubricating of bearing of grease lubrication mode is exactly the lubricated of steel ball surface, therefore, have influence on the lubricated of steel ball surface because the lubricating grease in the ball pocket is difficult for keeping, also just have influence on the life-span of bearing, cause working life less than mathematic(al) expectation.
Among the figure: steel ball 1, retainer 2.In the bearing working process, steel ball is rotation and revolution motion simultaneously, and when high rotation speed operation, grease self is because action of centrifugal force, all be outwards to throw away, behind the remaining one deck oil film of steel ball surface, the ball spoon of retainer can slowly scrape off grease in the revolution process.
Summary of the invention
The utility model technical issues that need to address have provided a kind of retainer with storage lubricating grease function, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: steel ball, retainer; Described steel ball is placed in the retainer; Retainer be shaped as sphere; There is one section annular at the bilateral symmetry place in described sphere.
Compared with prior art, the beneficial effects of the utility model are: owing to can have certain lubricating grease in the retainer ball pocket, improved the lubricating condition of bearing, prolonged bearing life.Through overtesting, the solid bearing life-span can be improved 30-50%, by rising to 3 year quality guarantee period 2 year original quality guarantee period.
Description of drawings
Fig. 1 is a prior art middle (center) bearing retainer structural representation;
Fig. 2 is the utility model structural representation;
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: steel ball 1, retainer 2; Described steel ball 1 is placed in the retainer 2; Retainer 2 be shaped as sphere; There is one section annular 3 at the bilateral symmetry place in described sphere;
Described annular 3 be arranged on spherical about, four side places up and down.
Principle of the present utility model is: the shape in the ball pocket is changed into by original sphere be with one section annular on the sphere, steel ball is contacted with spherical, but can preserve a certain amount of lubricating grease in annular and spherical contacting point: when steel ball revolve round the sun at a high speed and the rotation process in, there is grease to be thrown out of, at this moment understand some grease on the retainer and stored, stored position is the annular place.
After adopting the utility model, in the life-span of having improved bearing, the cycle that auto parts machinery is changed has obtained prolongation, has better met the needs in market.Test shows: adopt the bearing life of new structure retainer can improve 30-50%.
Claims (2)
1. the retainer with storage lubricating grease function comprises: steel ball (1), retainer (2); Described steel ball (1) is placed in the retainer (2); Retainer (2) be shaped as sphere; It is characterized in that: there is one section annular (3) at the bilateral symmetry place in described sphere.
2. the retainer of band according to claim 1 storage lubricating grease function is characterized in that: described annular (3) be arranged on spherical about, four side places up and down.
