Abstract
The utility model discloses a self -lubricating connecting rob bushing, including the bush body, be equipped with a plurality of independent pits on the internal surface of bush body. This bush can keep the whole oil film of connecting rob bushing surface of the work, guarantees that piston pin and connecting rob bushing do not have the dry friction to improve the piston pin, the reliability of connecting rob bushing.
Description
Technical field
The utility model relates to the field of accessories of internal-combustion engine, particularly a kind of selflubricating connecting rob bushing.
Background technique
In order to meet the sufficient lubrication between wrist pin and connecting rod, as shown in Figures 1 to 4, normally connecting rob bushing is set up a herringbone a, the lubricant oil being splashed to connecting rod small end by herringbone a drainage (herringbone a is communicated with oil inlet hole b), ooze into connecting rod small end and wrist pin contact surface to reach the effect of lubrication.
But above-mentioned conventional linkage lining has some problem following: 1, offer " people " word groove, lining pressure-bearing surface discontinuity can be caused; 2, lubricant oil skewness, the difficult overall formation of oil film; 3, away from the region of " people " word groove, lubricant oil is difficult to arrive, and there is the risk of dry friction.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Model utility content
The purpose of this utility model is to provide a kind of selflubricating connecting rob bushing, can keep the overall oil film of connecting rob bushing working surface, guarantee that wrist pin and connecting rob bushing are without dry friction, thus improve wrist pin, the reliability of connecting rob bushing.
For achieving the above object, the utility model provides a kind of selflubricating connecting rob bushing, comprises bush body, and the internal surface of bush body is provided with some independently pits.
Preferably, pit is covered with the internal surface of bush body.
Preferably, pit arranges in the form of a ring along the circumference of bush body.
Preferably, the sidewall of bush body is at least provided with an oil inlet hole.
Preferably, pit is rectangular slot.
Preferably, the degree of depth of pit is 0.005-0.008mm.
Preferably, the length of pit is not more than 2.5mm.
Preferably, the width of pit is 0.015-0.02mm.
Compared with prior art; the utility model has following beneficial effect: by designing some independently pits; when not affecting connecting rob bushing bearing capacity; the overall oil film of connecting rob bushing working surface can be kept; guarantee that wrist pin and connecting rob bushing are without dry friction; thus raising wrist pin, the reliability of connecting rob bushing.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Fig. 5 to Fig. 8, according to a kind of selflubricating connecting rob bushing of the utility model embodiment, comprise bush body, the internal surface of bush body is provided with some independently pits 2.Selflubricating connecting rob bushing described by this patent and the maximum difference of existing lining are exactly (see Fig. 1 to Fig. 4 by herringbone a, herringbone a is communicated with oil inlet hole b) change some independently pits 2 into, by lubricant oil being stored in these pits 2, lubricant oil and then spread to connecting rob bushing working surface, form oil film overall continuously, effectively prevent wrist pin and connecting rob bushing surface from occurring dry friction, thus improve the reliability of wrist pin and connecting rob bushing.Pit 2 in the present embodiment can effectively oil storage, contributes to the formation of overall oil film and keeps, and not affecting connecting rob bushing bearing capacity, uniform force, and processing is simple, performs convenience, is easy to popularization.
As a kind of preferred embodiment, pit 2 is covered with the internal surface of bush body.Guarantee that the surface of whole connecting rob bushing is lubricated.
As a kind of preferred embodiment, pit 2 arranges in the form of a ring along the circumference of bush body.
As a kind of preferred embodiment, the sidewall of bush body is at least provided with an oil inlet hole 1.The present embodiment is for 2.
As a kind of preferred embodiment, pit 2 is rectangular slot.As a kind of embodiment, the degree of depth of pit 2 can be designed as 0.005-0.008mm, and the length of pit 2 is not more than 2.5mm, and the width of pit 2 is 0.015-0.02mm.
To sum up, the selflubricating connecting rob bushing of the present embodiment, in actual application, can keep the overall oil film of connecting rob bushing working surface, guarantee that wrist pin and connecting rob bushing are without dry friction, thus improve wrist pin, the reliability of connecting rob bushing.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
