Abstract
The utility model discloses a gear shaft sleeve, which comprises a cylindrical shaft sleeve body, wherein the shaft sleeve body is provided with a shaft sleeve through hole for inserting a bearing on a gear; the side wall of the shaft sleeve body is provided with an oil addition hole which penetrates through the side wall of the shaft sleeve body; the oil addition hole is used for communicating the shaft sleeve through hole with the outer side of the shaft sleeve body; the shaft sleeve body comprises a steel outer layer and a copper inner layer; the inner side wall of the steel outer layer is attached to the outer side wall of the copper inner layer; and the inner side wall of the shaft sleeve through hole is provided with an annular groove. The outer layer of the gear shaft sleeve is a steel outer layer, the inner layer is a copper inner layer, the friction resistance performance of the inner side of the gear shaft sleeve is high, and the strength of the outer side is high, so that the gear shaft sleeve is more durable and the service life is longer.
Description
Technical field
The utility model relates to technical field of automobile parts, is specifically related to a kind of gear bush.
Background technique
Axle sleeve also is " axle bush ", is sliding bearing and the tactile part that is coupling, and the surface of axle sleeve is very smooth, generally makes with high-abrasive materials such as bronze, antifriction alloys, under special circumstances, also can make with timber, plastics or rubber.Be shaped as the semi-cylindrical of watt shape.During sliding bearing work, be provided with the very thin oil film lubricate of one deck between axle sleeve and the rotating shaft.If but because insufficient lubrication just have directly friction between axle sleeve and the rotating shaft, and existing gear bush adopts generally homogenous material to make, combination property is poor, generally can only reach single performance requirement.
Summary of the invention
The purpose of this utility model is: for the deficiencies in the prior art, the utility model provides the gear bush that a kind of rub resistance is effective, intensity is high.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of gear bush, comprise cylindrical axle sleeve body, described axle sleeve body is provided with the axle sleeve through hole that inserts for the gear upper bearing (metal), the sidewall of described axle sleeve body is provided with the charging hole that runs through axle sleeve base side wall, described charging hole is communicated with the outside of axle sleeve through hole and axle sleeve body, described axle sleeve body comprise the outer and copper internal layer of steel, the outer side wall of the outer field madial wall of described steel and copper internal layer is fitted, the madial wall of described axle sleeve through hole is provided with circular groove.
As preferably, plane, described circular groove place and described axle sleeve body shaft are to the perpendicular direction setting.After adopting above-mentioned preferred version, circular groove of the present utility model can better play the effect of temporary transient storage medium oil body, and fuel-displaced effect is better.
As preferably, described axle sleeve body is bent to form by steel disc and copper sheet, and forms the axle sleeve joint at the axle sleeve body, and a side of described axle sleeve body joint is provided with lug, and opposite side is provided with the lug groove that can embed for lug.After adopting above-mentioned preferred version, the connection effect at the two ends of gear bush is more firm.
As preferably, the edge of described axle sleeve body outer side wall is provided with outside chamfering, and the edge of described axle sleeve body madial wall is provided with inboard chamfering.After adopting above-mentioned preferred version, can effectively avoid the sharp-pointed place of gear bush to using installation personnel to damage, improve the Security of gear bush.
The skin of gear bush of the present utility model adopts steel outer as steel, and described copper internal layer adopts the copper internal layer, and the inboard crocking resistance of gear bush is high, and the intensity in the outside is high, makes gear bush more durable, longer service life.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
As shown in Figure 1, embodiment of the present utility model is a kind of gear bush specifically, comprise cylindrical axle sleeve body 1, axle sleeve body 1 is provided with the axle sleeve through hole 11 that inserts for the gear upper bearing (metal), the sidewall of axle sleeve body 1 is provided with the charging hole 12 that runs through axle sleeve body 1 sidewall, and charging hole 12 is communicated with the outside of axle sleeve through hole 11 and axle sleeve body 1.Axle sleeve body 1 comprise steel outer 13 and copper internal layer 14, the outer side wall of the madial wall of steel skin 13 and copper internal layer 14 is fitted, the madial wall of axle sleeve through hole 11 is provided with circular groove 15.
The vertical setting of axial direction of plane, circular groove 15 place and axle sleeve body 1.Axle sleeve body 1 is bent to form by steel disc and copper sheet, and forms axle sleeve joint 16 at axle sleeve body 1, and a side of axle sleeve body joint 16 is provided with lug 161, and opposite side is provided with can be for the lug groove 162 of lug 161 embeddings.The edge of axle sleeve body 1 outer side wall is provided with outside chamfering 17, and the edge of axle sleeve body 1 madial wall is provided with inboard chamfering 18.
The working principle of the working principle of gear bush of the present utility model and the gear bush of prior art is basic identical, and difference is: gear bush of the present utility model adopts different materials mixing manufacture internal layer and skin, has improved the combination property of gear bush.
