Abstract
The invention discloses an aluminum-titanium-magnesium alloy acupressure bearing bush which comprises a steel back material layer (1) and an aluminum-titanium-magnesium alloy layer (2), wherein a laser acupressure pit layer (3) is arranged on the aluminum-titanium-magnesium alloy layer (2); the thickness of the aluminum-titanium-magnesium alloy layer (2) is 0.25-2.05mm; and the diameters of the outer circles of the pits of the laser acupressure pit layer (3) are 0.005-0.022mm, and the depths of the pits are 0.005-0.022mm, and the density of the pits is 3/mm. Since the aluminum-titanium-magnesium alloy acupressure bearing bush is prepared from the novel alloy material, the contact area between the inner circle of the inner circle and the shaft diameter is dropped from 80% to 43% or so, thereby enhancing the linear slide speed of the inner circle surface of the bearing bush, eliminating the dry friction between the internal surface of the bearing bush and the shaft diameter due to lack of lubricating oil when starting the engine, and prolonging the service life. When starting the engine, the bearing bush can not be burnt; and when in use, the bearing can not be seized, and electroplating is not needed, so that the invention is completely environment-friendly.
Description
Technical field
The present invention relates to a kind of motor with the aluminum magnesium titanate alloy bearing shell of attacking a vital point.
Background technique
The copper lead alloy bearing shell that existing motor car engine is used; Though bearing capacity is preferably arranged; But its bearing shell surface must remedy through the way that increases electroplating surface, could satisfy the performance requirement of present motor, causes the higher and environmental pollution of cost thus; Follow the research and development of high-power, high rotating speed, high-performance, low emission level engine, its product can't satisfy the technical need of following power.
Summary of the invention
The technical problem that the present invention solves is: a kind of aluminum magnesium titanate alloy bearing shell of attacking a vital point is provided; Adopt the laser technology of attacking a vital point; Replace original Microsoft's layer with electrodeposited coating circle manufacturing in bearing shell; Process one deck pit Microsoft layer at inner surface of bearing bush, thereby improved bearing capacity, line Sliding velocity and the working life of bearing shell internal circular surfaces.
The technological scheme that the present invention takes is: this aluminum magnesium titanate alloy bearing shell of attacking a vital point comprises the steel backing material layer, and the aluminum magnesium titanate alloy-layer has the laser pit layer of attacking a vital point on the aluminum magnesium titanate alloy-layer;
Further, the aluminum magnesium titanate alloy layer thickness is 0.25～2.05mm;
Further, aluminum magnesium titanate alloy the attack a vital point pit outside diameter of pit layer of the laser of bearing shell of attacking a vital point is 0.005～0.022mm, and pit depth is 0.005～0.022mm, and pit density is 3/mm;
Further, the aluminum magnesium titanate alloy bearing shell of attacking a vital point comprises crankshaft bearing liner, connecting rod bearing shell, camshaft bush and balance bearing shell.
The technique effect that the present invention reaches is: this motor is with the aluminum magnesium titanate alloy bearing shell of attacking a vital point; Adopted the novel alloy material manufacture, made the area of contact of circle and the diameter of axle in the bearing shell be reduced to about 43%, improved the line Sliding velocity of bearing shell internal circular surfaces by original 80%; Eliminated motor when starting because of lacking inner surface of bearing bush that lubricant oil produces and dry friction between the diameter of axle; Prolonged the use birthday noodle, reduced requirement engine oil pressure, during startup not tile kilning, use in not seize, need not electroplate; Fully environmental protection is for the research and development of high-power, high rotating speed, high-performance, low emission level engine provide reliable bearing shell guarantee.

Embodiment
Below in conjunction with accompanying drawing principle of the present invention and characteristic are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
To shown in Figure 6, this aluminum magnesium titanate alloy bearing shell of attacking a vital point comprises steel backing material layer 1 according to Fig. 1, and aluminum magnesium titanate alloy-layer 2 has the laser pit layer 3 of attacking a vital point on aluminum magnesium titanate alloy-layer 2; Aluminum magnesium titanate alloy-layer 2 thickness are 0.25～2.05mm; The inner surface of bearing bush processing laser that matches with the diameter of axle at bearing shell 0.005～0.022mm pit of attacking a vital point; The attack a vital point pit outside diameter of pit layer 3 of laser is 0.005～0.022mm; Pit depth is 0.005～0.022mm; Pit density is 3/mm, and the aluminum magnesium titanate alloy bearing shell internal circular surfaces behind the processing pit does not need to do surface treatment again; The aluminum magnesium titanate alloy bearing shell of attacking a vital point comprises crankshaft bearing liner, connecting rod bearing shell, camshaft bush and balance bearing shell.
The attack a vital point steel backing material of bearing shell of aluminum magnesium titanate alloy adopts high-quality low carbon steel (HFST37/38-2G/3G); Alloy material adopts aluminum magnesium titanate alloy (aluminum magnesium titanate alloy material: Ti is 8～13%, Mg is 4～6%, Sn is 3～5%, Zn is 1～2.5%, Si is 0.5～1.8, Al surplus) to make; Its alloy surface not only has good line Sliding velocity, and has higher bearing load.
The attack a vital point processing technology step of bearing shell of aluminum magnesium titanate alloy is following: blank inspection → neck material → following sheet stock → towards steel seal → dash curved shaping → rough counterpart → car both ends of the surface and exterior angle in falling → towards oilhole → car oil groove → towards retention Hp → draw in counterpart plane and the interior angle of the falling the counterpart → deburring → polishing → right boring circle → laser attack a vital point processing → smart deburring → remanent magnetism processing → appearance test → wall thickness check → Checking of finished products → cleaning → immersion oil antirust → combo and packing; AlTi10Mg5 high temperature sintering or roll compacting are on HFST37/38-2G/3G the most at last, and AlTi10Mg5 thickness is 0.25～2.05mm.
The aluminum magnesium titanate alloy of the present invention bearing shell of attacking a vital point is mainly used in aeroengine, warship motor, heavy-duty car motor, large-scale engineering machinery etc.Along with standard that engine emission is constantly lowered the requirement is put into effect, the aluminum magnesium titanate alloy of the present invention bearing shell of attacking a vital point can satisfy the technical requirements of high pressure-charging, high pulling torque, high rotating speed, low emission level engine.
The above is merely mode of execution of the present invention; And unrestricted claim of the present invention; The equivalent transformation that every utilization specification of the present invention and accompanying drawing content are done directly or indirectly is used in other relevant technical field, all in like manner is included in the claim of the present invention.
