Abstract
The utility model discloses an Al-Ti-Mg alloy acupoint bearing shell. The Al-Ti-Mg alloy acupoint bearing shell comprises a steel backing material layer (1) and an Al-Ti-Mg alloy layer (2), and a laser acupoint pit layer (3) is arranged on the Al-Ti-Mg alloy layer (2); the Al-Ti-Mg alloy layer (2) is 0.25-2.05mm thick; and the excircle diameter of pits of the laser acupoint pit layer (3) is 0.005-0.022mm, the depth of each pit is 0.005-0.022mm, and the pit density is 3 per square meter. The Al-Ti-Mg alloy acupoint bearing shell is made of alloy materials, so that the contact area of the inner circle of the bearing shell and the shaft diameter is reduced from original 80% to about 43%. The line sliding speed of the surface of the inner circle of the bearing shell is improved, dry friction between the inner surface of the bearing shell and the shaft diameter generated due to lack of lubricating oil when an engine is started is eliminated, the service life is prolonged, the burning of the bearing shell in starting, and journal sticking in use can not occur, electroplating is not needed, and complete environment friendliness can be realized.
Description
Technical field
The utility model relates to a kind of motor with the aluminum magnesium titanate alloy bearing shell of attacking a vital point.
Background technique
The Cu-Pb Alloy Bearing that existing motor car engine is used, though preferably bearing capacity is arranged, but its bearing shell surface must be remedied by the way that increases electroplating surface, could satisfy the performance requirement of present motor, cause thus high expensive and environmental pollution, 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.
The model utility content
The technical problem that the utility model 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 of using electrodeposited coating to make in the bearing shell inner circle, make 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 utility model is taked 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 at 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 utility model reaches is: this motor is with the aluminum magnesium titanate alloy bearing shell of attacking a vital point, adopted the manufacturing of novel alloy material, so that the area of contact of bearing shell inner circle and the diameter of axle is reduced to about 43% by original 80%, improved the line Sliding velocity of bearing shell internal circular surfaces, eliminated motor when starting because lacking inner surface of bearing bush that lubricant oil produces and dry friction between the diameter of axle, the use birthday noodle have been prolonged, reduced the requirement to engine oil pressure, tile kilning not during startup, seize not in the use, need not electroplate, fully environmental protection is for high-power, high rotating speed, high-performance, the research and development of low emission level engine provide reliable bearing shell guarantee.

Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
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 at 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 liner internal circular surfaces behind the processing pit does not need to do surface treatment again; Aluminum magnesium titanate platform gold point cave bearing shell 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 (HFST37/38-26/3G), 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 as follows: blank inspection → neck material → lower sheet stock → rush steel seal → rush curved shaping → rough counterpart → car both ends of the surface and fall in exterior angle → rush oilhole → car oil groove → rush retention Hp → draw counterpart plane and the interior angle of falling the counterpart → deburring → polishing → right boring inner 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 HFST37/38-26/3G the most at last, and AlTi10Mg5 thickness is 0.25～2.05mm.
