Description
Technical field
The utility model relates to a kind of bearing shell with black composite coating, belongs to bearing parts technical field.
Background technique
Bearing shell is one of important component of sliding bearing, sliding bearing and the tactile part that is coupling, be shaped as the semi-cylindrical of watt shape, generally formed by steel backing, liner, steel backing mainly adopts steel material, in order to improve the frictional property on bearing shell surface, its inner lining surface of being everlasting powers on and plates one deck antifriction material, is commonly referred to electrodeposited coating.When sliding bearing work, bearing shell and axle journal form friction pair, and main failure forms is wearing and tearing and gummed.So to bearing shell, main basic demand is: have good antifriction quality, wear resistance, antiseizing; Good compliance, embeddability and running-in; Good thermal conductivity, thermostability; There is enough intensity; To lubricant oil have stronger adsorptive power, corrosion-resistant and be convenient to processing etc.And the coating of bearing shell mainly adopts ternary and quaternary alloy material at present, add and electroplate man-hour on bearing shell liner face, form thinner coating.
Along with the strengthening of power of IC engine and the raising of rotating speed and operating reliability and low-carbon environment-friendly standard raising, the important friction pair group of combustion motor (as connecting rod bearing shell, crank spindle watt etc.) has higher requirement, but above-mentioned ternary and quaternary alloy cannot further improve on bearing capacity, tribological property as the bearing shell of lining coating, and because they contain lead composition, also can pollute destruction to environment.To in the research of tiling corrosion, it is abnormal that spectrum analysis finds that there is non-ferrous metal concentration of element in addition; In spectrum, there is the submicron order wear particle of many non-ferrous components; Lubricant oil Moisture high UCL, acid number exceed standard, and have caused tiling corrosion.
Model utility content
The purpose of this utility model is just to provide the bearing shell with black composite coating that a kind of bearing capacity is high, tribological property is excellent, also has the advantage such as leadless environment-friendly, acid resistance corrosion simultaneously.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of bearing shell with black composite coating, formed by steel backing, liner, steel backing, liner are a watt shape, liner material is copper-based alloy material, liner sintering is on the inner headed face of steel backing, on the inner headed face of liner, also have a composite coating, this composite coating is made up of black MoS2+C composite material, and the thickness of composite coating is 0.005 ~ 0.025mm.
The bearing shell with black composite coating that adopts such technological scheme to make, due to MoS
2+ C composite coating is very thin, and load is mainly born by liner and steel backing, and bearing capacity can be guaranteed; Due to the MoS of Nano Particle
2the structural characteristics of+C composite coating all belong to stratiform hexagonal respectively to alienation, particularly MoS
2strong polarity S-Mo key of+C material has fabulous antifriction quality, due to the MoS of Nano Particle
2+ C composite coating is a kind of microcellular structure, has good lipophile, self-enrichment, can possess all the time the stable physical absorption film of one deck at surface of friction pair, avoids adhesive wear, and therefore it has outstanding tribological property; Experiment shows, MoS
2+ C composite coating also has stability to acidity and radioactive ray, and corrosion resistance is stronger; MoS2+C composite coating is not leaded, therefore has advantages of environment friendly and pollution-free.
