Abstract
The utility model relates to the field of motor vehicle engines, in particular to an aluminum bronze bearing bush for a motor vehicle engine, comprising a steel backing, and the aluminum bronze bearing bush is characterized in that a layer of aluminum bronze alloy is attached on the steel backing. The thickness of the aluminum bronze alloy layer of the aluminum bronze bearing bush for the motor vehicle engine is 1-3 mm, and the mass percentage of aluminum in components is 7-10 percent, and the balance of copper. The aluminum bronze bearing bush for the motor vehicle engine has long service life and higher abrasive resistance and anti-fatigue performance, and is free from lead and is environment-friendly.
Description
Technical field
The utility model relates to the motor car engine field, particularly a kind of motor car engine aluminum bronze bearing shell.
Background technique
Existing motor car engine bearing shell, in order to improve the frictional property on bearing shell surface, be everlasting its aperture surface top pouring one deck or two-layer antifriction material, for improving its wear resistance, usually adopt leaded tin bronze alloys, bearing capacity is less, and because of toxicity plumbous in the alloy is bigger, its application area is restricted day by day.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of unleaded, wear and corrosion behavior and the good motor car engine of anti-fatigue performance aluminum bronze bearing shell.
Solving the problems of the technologies described above the technological scheme that is adopted is: motor car engine of the present utility model aluminum bronze bearing shell is characterized in that having adhered to layer of aluminum bell metal layer on steel backing.
Described motor car engine is 1 to 3 millimeter with the thickness of the aluminium bronze layer of aluminum bronze bearing shell.
Use the thickness of the aluminium bronze layer of aluminum bronze bearing shell to be 1,2 or 3 millimeter for above-mentioned motor car engine.
Described motor car engine is that aluminium content mass percent is 7-10% with the composition of the aluminium bronze layer of aluminum bronze bearing shell, and all the other are copper.
Can be 7,8,9,10% for above-mentioned motor car engine with aluminium content mass percent in the composition of the aluminium bronze layer of aluminum bronze bearing shell, all the other are copper.
The beneficial effects of the utility model are:
At first, motor car engine of the present utility model effectively raises working life with the aluminum bronze bearing shell; Secondly, motor car engine of the present utility model is unleaded with the aluminum bronze bearing shell, has the environmental protection advantage;
Once more, motor car engine is good with aluminum bronze bearing shell wear resistance, the anti-fatigue performance excellence.
Description of drawings:
Fig. 1 is a sectional view of the present utility model;
Label declaration in the accompanying drawing:
The 1-steel backing; 2-aluminium bronze layer.
Embodiment
As shown in Figure 1, aluminum bronze bearing shell lining of the present utility model comprises steel backing 1 and aluminium bronze layer 2.The composition of aluminium bronze layer is: the content of aluminium is 8%-10%, and copper content is 92%-90%.Aluminium bronze layer 2 is that the method by the powder loose sintering is cured on the steel backing 1.Concrete preparation process is: steel backing 1 is carried out the oil removing cleaning; Evenly the layer overlay particle size is the mixed-powder of-200 purpose aluminium and copper on steel backing 1, and wherein aluminium accounts for 9% of mixed-powder gross weight, and steel backing 1 and mixed-powder is sent into together carry out sintering in the stove; Described sintering process parameter is: sintering temperature is that 950-980 ℃, sintered heat insulating time are that 1-2 hour, sintering atmosphere are that purity surpasses 99.95% hydrogen; Sintering carries out roll extrusion with the material that adheres to the aluminium bronze layer on the gained steel backing 1 after finishing, and promptly makes motor car engine aluminum bronze bearing shell.
