Description
Technical field
The present invention relates to coated material field, particularly a kind of for the anti-lock material for engine crankshaft.
Background technology
Piston, linkage assembly are connected on bent axle, the pressure produced when bent axle subjects fuel mixture burning by piston and connecting rod, and change the to-and-fro movement of piston into rotary motion.A slide unit between crankshaft-and-connecting-rod, becomes bearing shell, and it forms a sliding surface bearing together with machine oil.Adopt sliding friction between the bent axle of Otto cycle engine and big end, in crank pin end pore, have upper and lower two semicircular tiles (namely bearing shell), tile and machine oil form a sliding surface bearing jointly.Tile is made up of stalloy, and inside steel disc, be cast with the alloy layer reducing friction, and this alloy layer can play the effect keeping oil film, reduce friction.The inner side of tile is also processed with oil groove, in order to store machine oil, ensures to lubricate reliably.One end of tile is fixed on the inwall of big end, and the other end is then connected with bent axle by oil film.Gap between tile and bent axle is very little, and by after suitable break-in, this gap can be very even.Have the uniform oil film of one deck in this minimum gap, these machine oil oil films just serve as the effect of steel ball in two-cycle engine rolling bearing.We know, the normal idling of engine generally to turn left the right side at 800-900, and that is between engine crankshaft and connecting rod, per minute will rotate about 800-900 time.This is still at idling mode, if it is even higher that high engine speeds running per minute at least will reach the rotating speed that 4000-5000 turns, in the face of so high rotating speed, the friction between tile and neck of bent axle is very violent, and the machine oil now bearing lubrication just seems abnormal important.Once engine lacks oil lubricating, just general without steel ball in rolling bearing seemingly, metal to-metal contact can be produced between tile and neck of bent axle, this situation is very terrified: so rub fast, also amount of heat can be produced while the wearing and tearing of extreme aggravation tile, thus cause tile to burn, Here it is our Bearing score of often saying.Once not only not have machine oil between crankshaft-and-connecting-rod, and the alloy layer lubrication of antifriction all loses, and can cause locking between crankshaft-and-connecting-rod.And when temperature is too high, the radial radius of bent axle increases, and with bearing shell (tile) swelling, is also one of reason causing locking between bent axle and connecting rod, and the lubrication that machine oil inferior in addition causes also easily causes the generation of locking situation not.
Therefore, need to solve be when engine motor oil poor quality effectively lubricating or engine motor oil can not be provided to reduce and can not to crankshaft-and-connecting-rod between provide enough lubricate, how to avoid producing metal to-metal contact between tile and bent axle and the generation that finally causes locking phenomenon between crankshaft-and-connecting-rod.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of anti-lock material for engine crankshaft, effectively lubricating or engine motor oil can not be able to be provided to reduce in engine motor oil poor quality and can not to crankshaft-and-connecting-rod between provide when enough lubricating, effectively avoid producing metal to-metal contact between tile and bent axle and the generation that finally causes locking phenomenon between crankshaft-and-connecting-rod.
Anti-lock material for engine crankshaft of the present invention, coated material raw material is composed of the following components by weight: PAG polyethers base oil 50-70 part, improved plant base synthetic ester oxidation sunflower seed oil 15-30 part, tetrafluoroethylene 3-8 part, curing tungsten powder 1-5 part, carborundum powder 5-10 part, fluorographite powder 5-15 part, soft metal 5-10 part, fire retardant 1-3 part, melamine cyanuric acid adducts 1-5 part, oxidation inhibitor 0.1-0.5 part;

Further, described soft metal is one or more mixtures in nickel powder, aluminium powder, copper powder, silver powder, zinc powder, bronze, glass putty, magnesium powder, indium powder;
Further, described oxidation inhibitor is alkylated diphenylamine;
Further, described fire retardant is one or more mixtures in antimonous oxide, zinc borate, red phosphorus; For fire-retardant, there is extraordinary synergy, strengthen flame retardant effect.
Further, described red phosphorus is microencapsulated powder oil.
Further, the granularity of described curing tungsten powder, carborundum powder, fluorographite powder is 0.1 ~ 1um.
Anti-lock material for engine crankshaft of the present invention can be prepared by the following method and obtain.
By setting weight part each component added mixing and stirring in reactor and be warming up to 180-200 DEG C, insulation 2-3 hour, take out mixture after cool to room temperature, obtain the anti-lock material for engine crankshaft of the present invention through fully grinding, anti-lock material of the present invention is paste.
The present invention also discloses a kind of using method of the anti-lock material for engine crankshaft, directly can spread upon the crankshaft journal surface between neck of bent axle and bearing shell (tile) or/and bearing shell is surperficial, has excellent corrosion-resistant, high-temperature-resistant anti-lock performance.
Beneficial effect of the present invention: the anti-lock material for engine crankshaft of the present invention, spread upon the crankshaft journal surface between neck of bent axle and bearing shell (tile) or/and bearing shell is surperficial, effectively lubricating or engine motor oil can not be able to be provided to reduce in engine motor oil poor quality and can not to crankshaft-and-connecting-rod between provide when enough lubricating, enough lubrications are provided, before the load that reaches capacity, the viscous deformation of friction surface is born by coated material entirely, avoid under the condition of lubricating oil wretched insufficiency, the direct contact of friction surface, very high temperature can be born, the supercoat not easily washed off and burn, there is good antioxidant property, not carbonization under high temperature, noncoking, do not run off, and have outstanding high temperature lubricating, to metal parts, there is fabulous waterproof, antirust, protection against corrosion, anti-Fretting Wear Behavior, solid dry film lubrication can be formed at the environment higher than more than 200 degree, the effect of lubricating and preventing metal sintering stuck is played at up to the temperature of 800 DEG C, effectively avoid producing metal to-metal contact between tile and bent axle and the generation finally causing locking phenomenon between crankshaft-and-connecting-rod, improve the work-ing life of engine, and the coated material being coated in the surface between crankshaft-and-connecting-rod can not affect the fuel feeding of oil circuit, engine can provide normal fuel injection to crankshaft-and-connecting-rod, therefore, coated material of the present invention provides double insurance to engine undoubtedly, the generation of effective minimizing fault.
