Abstract
The utility model discloses a wear-resisting bearing compising a steel ball, an inner steel bushing, an external steel bushing, steel ball clamp, etc. The utility model is characterized as follows: the inner wall of the external steel bushing is added with a boron carbide external steel bushing internal layer; the external wall of the inner steel bushing is added with a boron carbide inner steel bushing external layer; the inner wall of the steel ball clamp is added with a boron carbide steel ball clamp internal layer; the surface of the steel ball is added with a boron carbide steel ball external layer. The utility model overcomes defects of bearing used in current community: the abradability of direct friction rotation between the steel ball and the steel bushing is bad and service life is short, etc. The utility model adapts to various mechanical rotary mechanism installation and use, like bearings, rollers, etc.
Description
Technical field
The utility model relates to the support field of axle, roller rotation, a kind of specifically bearing that is used for fixing rotations such as axle, roller.
Background technique
At present, employed bearing in the society all is with the rotation that directly rubs of steel ball and steel bushing, its shortcoming be wear no resistance, the life-span is short.
Summary of the invention
The utility model is for solving present bearing, and steel ball and steel bushing directly rub, and rotation wears no resistance, the problem of life-span weak point, and a kind of bearing that is added with wearing layer is provided.
The utility model is for solving the problems of the technologies described above, the technological scheme that is adopted is, a kind of anti-friction bearing is to be made of steel ball, interior steel bushing, outer steel sleeve, steel ball card etc., its special way is: be added with boron carbide outer steel sleeve internal layer on the inwall of outer steel sleeve, be added with steel bushing skin in the boron carbide on the outer wall of interior steel bushing, be added with boron carbide steel ball card internal layer on the inwall of steel ball card, be added with boron carbide steel ball skin on the surface of steel ball.
During work; rub between the boron carbide steel ball card internal layer in boron carbide outer steel sleeve internal layer by the lip-deep boron carbide steel ball of steel ball on the outer and outer steel sleeve inwall, the boron carbide on the interior steel bushing outer wall on steel bushing skin, the steel ball card inwall, protected steel ball, interior steel bushing, outer steel sleeve, steel ball card.Utilize the wear resistance of boron carbide, improved the working life of bearing.
Technique effect of the present utility model is, adopts above-mentioned technological scheme, can realize a kind of durable novel bearing.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further specified.
Fig. 1 is a structure longitudinal section of the present utility model, and the accompanying drawing that makes an abstract.
In the drawings, steel bushing skin, 4 interior steel bushings, 5 steel ball cards, 6 pearl card internal layers, 7 steel ball skins, 8 steel balls in 1 outer steel sleeve, the 2 outer steel sleeve internal layers, 3.
Embodiment
As shown in the figure, be added with boron carbide outer steel sleeve internal layer 2 on the inwall of outer steel sleeve 1, be added with steel bushing skin 3 in the boron carbide on the outer wall of interior steel bushing 4, be added with boron carbide steel ball card internal layer 6 on the inwall of steel ball card 5, be added with boron carbide steel ball skin 7 on the surface of steel ball 8.
During work; by rubbing between the boron carbide steel ball card internal layer 6 on steel bushing skin 3, steel ball card 5 inwalls in the lip-deep boron carbide steel ball outer 7 of steel ball 8 and the boron carbide outer steel sleeve internal layer 2 on outer steel sleeve 1 inwall, the boron carbide on interior steel bushing 4 outer walls, steel ball 8, interior steel bushing 4, outer steel sleeve 1, steel ball card 5 have been protected.
Claims (1)
1, a kind of anti-friction bearing is to be made of steel ball, interior steel bushing, outer steel sleeve, steel ball card etc., it is characterized in that: be added with boron carbide outer steel sleeve internal layer on the inwall of outer steel sleeve, be added with steel bushing skin in the boron carbide on the outer wall of interior steel bushing, be added with boron carbide steel ball card internal layer on the inwall of steel ball card, be added with boron carbide steel ball skin on the surface of steel ball.
