Abstract
The invention discloses a bimetallic balance bearing which has the advantages of good lubrication condition, long service life and reduced manufacturing cost. The bimetallic balance bearing comprises a cylindrical base body, namely a steel sleeve layer, wherein a copper alloy layer is arranged at the inner periphery of the steel sleeve layer, a plurality of grooves are formed in the steel sleeve layer, bulges are formed on the copper alloy layer, the grooves and the bulges are intermeshed, the steel sleeve layer has the thickness of 6mm, and the copper alloy layer has the thickness of 3mm; as a further improvement, a plurality of oil holes, a plurality of annular oil grooves and a plurality of oblique oil grooves are formed in the internal wall of the copper alloy layer, and the annular oil grooves and the oblique oil grooves are communicated with the oil holes. The technical scheme provided by the invention is applicable to automobile balance bearings.
Description
Technical field
The present invention relates to a kind of automobile component, relate in particular to a kind of bimetal equalizer bearing for automobile suspension system.
Background technique
Bearing works to fix and reduce load friction factor in mechanical-force-transmission process, bearing can not only bear the load of axle, and there is the effect of anti-attrition and vibration damping, and for the equalizer bearing using in heavy-load automobile, because vehicle capacity is large, road conditions complexity, work under hard conditions, thereby the power acting on balance shaft bearing not only has axial force, radial force, and also have various composite force and impact force, especially common equalizer bearing lubricating condition is poor, when work, friction factor is large, bearing inner wall easily weares and teares, thereby cause balance shaft bearing frequent breakage, in addition because the equalizer bearing size of applying on heavy-load automobile is relatively large, and material generally adopts Cuprum alloy, thereby causes manufacture cost higher.
Summary of the invention
The bimetal equalizer bearing that the technical problem to be solved in the present invention is to provide that a kind of lubricating condition is good, long service life, manufacture cost are economized.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The present invention includes cylindrical base, described matrix is steel bushing layer, in described steel bushing layer, week be provided with copper alloy layer, described steel bushing layer is provided with some grooves, described copper alloy layer is provided with projection, described groove and projection are intermeshing, and the thickness of described steel bushing layer is 6 millimeters, and the thickness of described copper alloy layer is 3 millimeters.
As preferably, described copper alloy layer inwall is provided with some oilholes and some annular oil grooves, is also provided with some oblique oil grooves, and described annular oil groove and oblique oil groove and oilhole are interconnected.
The present invention compared with prior art, has following obvious advantage and beneficial effect:
1, lubricating condition is good.Because the present invention adopts inwall, oilhole is set, and the annular oil groove being communicated with oilhole and oblique oil groove, thereby guarantee that grease is covered with inwall of the present invention, thus lubricating condition effectively improved.
2, long service life.Because the present invention is by increasing oil groove quantity, improve working surface lubricating condition, be conducive to reduce friction factor, improve working life.
3, manufacture cost is economized.The present invention adopts steel bushing and the combination of Cuprum alloy cover, thereby has reduced the consumption of Cuprum alloy, effectively reduces manufacture cost.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is A-A cut-away view in Fig. 1.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the present invention is described in further detail:
As shown in Figure 1 and Figure 2: the present invention includes cylindrical base 1, described matrix 1 is steel bushing layer, in steel bushing layer, be provided with copper alloy layer 2 week, steel bushing layer is provided with groove 3, copper alloy layer 2 is provided with projection 5, groove 3 is intermeshing with projection 5, be conducive to like this improve the combination fastness of steel bushing layer and copper alloy layer, the thickness of steel bushing layer 2 is 6 millimeters, the thickness of copper alloy layer 2 is 3 millimeters, copper alloy layer 2 inwalls are provided with oilhole 6 and annular oil groove 7, are also provided with oblique oil groove 8, and annular oil groove 7 and oblique oil groove 8 are interconnected with oilhole 6.
