Abstract
The utility model discloses a bimetallic sliding bearing with a rhombic lubrication indentation, aims at providing a bimetallic sliding bearing with a rhombic lubrication indentation which has a low manufacture cost, a simple structure, a good lubricating property and a reasonable material. The utility model cranks out a shaft housing with a quilt by using a metal plate with a sintering aldary on the surface of a steel plate, which is characterized in that the aldary is a bronze alloy, the bronze alloy surface of the inner circumference or the outer circumference of the shaft housing is pressed with uniform distributed rhombic blind holes. The utility model can store lubricants in the rhombic bind holes and has the advantages of a large lubricant reserve, a uniform lubricant distribution, a full lubrication, a convenient use and maintenance, a good heat transfer effect, a high copper operation factor as a lubrication indentation.
Description
Technical field
The utility model relates to a kind of sliding bearing, relates in particular to a kind of bimetal sliding bearing that is shaped on rhombus oil cave.
Background technique
Bell metal is used widely as antifriction metal because its wear resistance is good, plasticity is high, running-in characteristic good, the good and anti-bonding property of thermal conductivity reaches well and the excellent adsorption of oil.In order to reduce the friction of axle sleeve and journal surface, add lubricant oil on the sliding pair surface, make between axle sleeve and the axle journal and form oil film, the surface of part slide relative is spaced, thereby reduces the wearing and tearing of the friction factor and the part of sliding pair.And the sliding bearing of general bell metal is to make with bell metal all over, the cost of making is higher, be shaped on oil groove at slidingsurface on the structure, oil reserve is little, often can not in time add lubricant oil in actual use and cause oil-break " interlock ", or owing to needing often to refuel to reduce machine work efficient.
The model utility content
The purpose of this utility model be to provide a kind of low cost of manufacture, simple in structure, greasy property good, with material reasonably with the bimetal sliding bearing in rhombus oil cave.
In order to reach above-mentioned requirements, this structure is: being used in the surface of steel plate sintering has the bimetal plate of Cuprum alloy to make the axle sleeve of being with open seam, it is characterized in that described Cuprum alloy is a bell metal, on the bell metal surface of axle sleeve inner circumference or excircle, be suppressed with equally distributed rhombus blind hole.
According to the bimetal sliding bearing in above-mentioned band rhombus oil cave, can oil storage in the rhombus blind hole, as oily cave, it is big to have oil reserve, cloth oil evenly, lubricated fully, working service convenience, good heat dissipation effect, advantage that the copper material utilization ratio is high.

Fig. 2 is the A-A cutaway view Amplified image of Fig. 1;
Fig. 3 is the plan view of the bimetal sliding bearing in the band rhombus oil cave after being shaped;
Fig. 4 is the plan view of Fig. 3.
Wherein: 1, steel plate; 2, bell metal layer; 3, rhombus blind hole; 4, open seam; 5, internal surface.
Embodiment
Below in conjunction with accompanying drawing the utility model content is further described.
Fig. 1, Fig. 2 are the structural drawing of the bimetal plate in band rhombus oil cave.It is the bimetal plate at the bell metal layer 2 of steel plate 1 surperficial sintering QSn6.5-0.1, is suppressed with into the interrupted rhombus blind hole 3 of arranging of inclination on the surface of bimetal plate bell metal layer 2.Again according to the specification blanking of sliding bearing, bell metal layer 2 is rolled internal surface at sliding bearing, the bimetal sliding bearing that the spirality that is formed with open seam 4 is intermittently arranged rhombus oil cave as shown in Figure 3, Figure 4, wherein the gross area of rhombus blind hole 3 be band rhombus oil cave bimetal sliding bearing internal surface 5 gross areas 25%.Also can oppositely roll, be shaped according to usage requirement, make the bell metal layer roll outer surface at sliding bearing, the gross area of rhombus blind hole 3 be 30% of total outer surface area.Used bell metal can also be made the bimetal sliding bearing in band rhombus oil cave of QSn8-0.3 or CuZn6Sn6Pb3 or CuPb10Sn10 except QSn6.5-0.1.
Claims (5)
1, the bimetal sliding bearing in band rhombus oil cave, being used in the surface of steel plate sintering has the bimetal plate of Cuprum alloy to make the axle sleeve of being with open seam, it is characterized in that described Cuprum alloy is a bell metal, on the bell metal surface of axle sleeve inner circumference or excircle, be suppressed with equally distributed rhombus blind hole.
2, the bimetal sliding bearing in the oily cave of band rhombus according to claim 1 is characterized in that described bell metal is meant QSn8-0.3 or QSn6.5-0.1 or CuZn6Sn6Pb3 or CuPb10Sn10.
3, the bimetal sliding bearing in band rhombus according to claim 1 and 2 oil cave, the gross area that it is characterized in that described rhombus blind hole account for axle sleeve internal surface or total outer surface area 20% to 35% between.
4, the bimetal sliding bearing in the oily cave of band rhombus according to claim 1 and 2 is characterized in that described axle sleeve is the thin-walled axle sleeve through rolling of band open seam.
5, the bimetal sliding bearing in the oily cave of band rhombus according to claim 1 and 2 is characterized in that the helical pattern that being scattered in of described rhombus blind hole is interrupted.
