Abstract
The invention provides a bearing which comprises a bearing inner ring and a bearing outer ring; metal balls capable of rolling are arranged between the bearing inner ring and the bearing outer ring; a shaft hole is arranged in the center of the bearing inner ring; an oil hole is arranged in the shaft hole; the oil hole forms an oil channel, is communicated with the outer side of the shaft hole and is also communicated with the inner wall of the bearing outer ring; and a lubricating agent or lubricating oil can be added through the oil hole, so that better lubricating effect is realized among the metal balls, the service life is prolonged, and the noise generated in the operation of the bearing is reduced. Meanwhile, the bearing has the advantages of simple structure and reliability in use.
Description
Technical field
The present invention is specifically related to a kind of bearing.
Background technique
General bearing all comprises outer race and bearing inner ring, and the Metal Ball that can roll is arranged between bearing inner ring and outer race.If get rusty easily or wear and tear but grown back Metal Ball service time, cause the noise of bearing big, Metal Ball shortens working life.
Summary of the invention
The object of the present invention is to provide high lubricating effect, Metal Ball long bearing service time.
The technological scheme that realizes above-mentioned purpose is following:
A kind of bearing comprises bearing inner ring and outer race, is provided with the Metal Ball that can roll between bearing inner ring and the outer race; Said bearing inner ring center is provided with axis hole; Axis hole is provided with oilhole, and oilhole forms oil duct and communicates and communicate with the outer race inwall with the axis hole outside, can add oiling agent or lubricant oil through oilhole; Make to have better lubrication effect between the Metal Ball, increase the service life and the noise when reducing bearing operation.
Wherein, said oilhole is one or more, can add lubricant oil through a plurality of holes, reaches better effect.
Wherein, said oilhole and oil duct equal diameters, the convenient lubricant oil that adds.
Beneficial effect of the present invention: the present invention can pass through to add between lubricant oil to bearing inner ring and the outer race from oilhole, and high lubricating effect is simple in structure, uses reliable.
Description of drawings
Fig. 1 is a structural scheme of mechanism of the present invention.
Description of reference numerals
The 1-outer race; The 2-bearing inner ring; The 3-oilhole; The 4-oil duct; The 5-Metal Ball; The 6-axis hole.
Embodiment
See also Fig. 1; A kind of bearing; Comprise bearing inner ring 1 and outer race 2, be provided with the Metal Ball 5 that can roll between bearing inner ring 1 and the outer race 2, said bearing inner ring 2 centers are provided with axis hole 6; Axis hole 6 is provided with oilhole 3, and oilhole 3 forms oil duct 4 and communicates with axis hole 6 outsides and communicate with outer race 1 inwall.
Preferably, said oilhole 3 is a plurality of, can add lubricant oil from a plurality of holes, reaches better lubrication effect.
Preferably, the equal diameters of said oilhole 3 and oil duct 4, the convenient lubricant oil that adds.
The present invention can pass through to add between lubricant oil to bearing inner ring and the outer race from oilhole, and high lubricating effect is simple in structure, uses reliable.
More than having described structure of the present invention forms and the preparation method; The present invention is not restricted to the described embodiments; Under the prerequisite that does not break away from spirit and scope of the invention; The various changes and modifications of being done according to the present invention, all within protection scope of the present invention, protection scope of the present invention limits with claims and equivalent thereof.
