Abstract
The utility model provides a bearing. The bearing 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 bearing hole is arranged in the center of the bearing inner ring, and an oil hole is arranged in the bearing hole. The oil hole forms an oil channel and is communicated with the outside of the bearing hole and the inner wall of the bearing outer ring, lubricating agent or lubricating oil can be filled in through the oil hole, and therefore good lubrication effect between the metal balls can be achieved, service life can be prolonged and noise of the bearing in the process of operation can be reduced. In addition, the bearing has the advantages of being simple in structure and reliable to use.
Description
Technical field
The utility model 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 rear Metal Ball service time, cause the noise of bearing large, Metal Ball shortens working life.
The model utility content
The purpose of this utility model is to provide high lubricating effect, Metal Ball long bearing service time.
The technological scheme that realizes above-mentioned purpose is as follows:
A kind of bearing, comprise bearing inner ring and outer race, be provided with the Metal Ball that to roll between bearing inner ring and the outer race, described 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 by oilhole, so that have better lubrication effect between the Metal Ball, increase the service life and the noise when reducing bearing operation.
Wherein, described oilhole is one or more, can add lubricant oil by a plurality of holes, reaches better effect.
Wherein, described oilhole and oil duct equal diameters, the convenient lubricant oil that adds.
The beneficial effects of the utility model: the utility model can pass through to add lubricant oil between 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 the utility model structural scheme of mechanism.
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 to roll between bearing inner ring 1 and the outer race 2, described 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, described oilhole 3 is a plurality of, can add lubricant oil from a plurality of holes, reaches better lubrication effect.
Preferably, the equal diameters of described oilhole 3 and oil duct 4, the convenient lubricant oil that adds.
The utility model can pass through to add lubricant oil between 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 utility model forms and the preparation method; the utility model is not restricted to the described embodiments; under the prerequisite that does not break away from the utility model spirit and scope; the various changes and modifications of doing according to the utility model; all within protection domain of the present utility model, protection domain of the present utility model limits with claims and equivalent thereof.
