Abstract
The utility model relates to a bearing bush, which comprises a bearing bush body, wherein the bearing bush body is in an arc shape, an oil duct is arranged on the inner surface of the bearing bush body, and the bearing bush is provided with a plurality of through holes which are communicated with the oil duct. With the adoption of the technical scheme, the service life of the bearing bush is prolonged.
Description
Technical field
The utility model relates to a kind of bearing shell.
Background technique
Bearing shell is the part that sliding bearing contacts with rotating shaft, and the general high-abrasive materials such as bronze, antifriction alloy that adopt are made.Existing a kind of bearing shell, include the bearing shell body, described bearing shell body is a circular arc, the bearing shell body internal surface of this structure directly contact with the rotating shaft outer surface and area of contact big, thereby make that the frictional ratio between bearing shell body and the rotating shaft is bigger, when the rotating shaft high speed rotating, can produce a large amount of heats, if long-time use may burn out bearing shell, make that the working life of bearing shell is short.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of bearing shell of long service life.
The technical solution of the utility model: a kind of bearing shell, include the bearing shell body, described bearing shell body becomes circular-arc, and described bearing shell body internal surface is provided with oil duct, also is provided with some through holes that are communicated with oil duct on the described bearing shell body.
Adopt technique scheme, in the bearing shell body internal surface oil duct is set, on the bearing shell body, through hole is set, can in this oil duct, add certain lubricant oil by this through hole, make described bearing shell body and rotating shaft when work, can form certain oil film between them, thereby can not produce a large amount of frictions, prolong the working life of bearing shell effectively.
Further improvement of the utility model: described oil duct two ends extend to the both ends of the surface of bearing shell body.
Adopt above-mentioned further improvement, described oil duct two ends extend to the both ends of the surface of described bearing shell body respectively, when the lubricant oil in the described oil duct is changed, lubricant oil can directly flow out bearing shell from the two ends of oil duct, and this is external, because if lubricant oil uses for a long time, can make that its effect is bad, make that the friction between described bearing shell body and the rotating shaft increases gradually, be unfavorable for prolonging the working life of described bearing shell.
Of the present utility modelly further improve: described oil duct is and coaxial circular-arc of described bearing shell body again.
Adopt above-mentioned further improvement again, described oil duct and the coaxial setting of bearing shell body, the sense of rotation that is oil duct and described rotating shaft is provided with in the same way or oppositely, can make things convenient for contacting of lubricant oil and rotating shaft in the oil duct, guarantees that better lubricant oil is mobile more smooth and easy in oil duct.
Further improvement more of the present utility model: described through hole is 2.
Adopt and above-mentionedly further improve again, described through hole is provided with two can be conveniently to the perfusion of lubricant oil in the oil duct, practical more.

Fig. 2 is the worm's eye view of the utility model specific embodiment.
Embodiment
As shown in Figure 1, 2, a kind of bearing shell, include bearing shell body 1,1 one-tenth of described bearing shell body is circular-arc, described bearing shell body 1 internal surface is provided with oil duct 2, wherein, internal surface is the surface that bearing shell contacts with rotating shaft, also is provided with some through holes 3 that are communicated with oil duct 2 on the described bearing shell body 1, in the utility model specific embodiment, described through hole 3 is 2, certainly, more through hole 3 also can be set, still, more through hole 3 is set reduces the intensity of bearing shell, and then influence the working life of bearing shell.
In the utility model specific embodiment, described oil duct 2 two ends extend to the both ends of the surface 11 of bearing shell body 1, and described oil duct 2 is and coaxial circular-arc of described bearing shell body 1.Certainly, oil duct 2 also can be set to alternate manner, and still, the oil channel structure that provides in the utility model specific embodiment can conveniently be changed the lubricant oil in the oil duct 2, use is very convenient and can guarantee that lubricant oil is mobile more smooth and easy in oil duct 2, and then has prolonged the working life of bearing shell.
Claims (4)
