Summary of the invention

The invention solves in the existing in prior technology toothing operation process and have noise, thereby influence the technical problem of service life of gear etc., provide in a kind of gear operation process noise less, can prolong the lubricating grease of service life of gear.

The present invention has also solved the technical problem of the aspects such as roughened metal surface reparation of existing in prior technology gear, and a kind of lubricating grease that can repair the roughened metal surface of gear is provided.

Above-mentioned technical purpose of the present invention solves by the following technical programs: the used lubricating grease of a kind of motor gearbox is characterized in that the each component and the content (weight percent) that are comprised are respectively: lithium 12-hydroxy stearate: 12%～16%; Lithium salicylate: 2.6%～3.3%; Phenyl-2-aminonaphthaalene: 0.9%～1.1%; Barium mahogany sulfonate: 1.7%～2.3%; Molybdenumdisulphide: 6.2%～7.6%; Sulfur fluoride is for boric acid fat amine salt: 2.7%～3.3%; How pure glucosides is: 9.2%～10.5%; All the other are synthetic base oil.

Lubricating oil is that several additives modulation that the base oil by the different grades viscosity is equipped with different ratios form.The base oil quality is most important for lubricants performance, and it provides most basic lubricated, the cooling of lubricating oil, performance such as anti-oxidant, anticorrosive.But, in lubricating oil, also comprised the additive that improves its over-all properties in order to improve the performance of lubricating oil.The synthesis type base oil is just refined into the base oil that macromole is formed through complicated chemical reactions such as polymerization, catalysis again from the coal mine gas in the crude oil or ethene, propylene that Sweet natural gas disperseed out.In itself, its uses is composition preferably in the crude oil, chemical reaction and see through the molecular conformation that artificial control is issued to expection in addition, its molecular arrangement is neat, the ability of opposing extraneous variable is very strong naturally, therefore the synthetic oil quality is better, and it is more much better than than mineral oil naturally to the ability that thermally-stabilised, anti-oxidant reaction, anti-viscosity change.

Lithium 12-hydroxy stearate wherein can play certain densification to base oil.Barium mahogany sulfonate is the most basic, a most frequently used inhibiter of producing slushing oil.The oil soluble of this product is good, can form firm adsorption film in the metallic surface, and corrosion takes place to suppress metal to contact with airborne oxygen and moisture.Under wet heat condition and under the salt fog condition, this product all has good anti-rust properties to ferrous metal and non-ferrous metal, acidic medium such as carbonic acid gas, sulfurous gas, hand perspiration etc. all there is neutralizing effect preferably, can be in order to the preparation replacement slushing oil, rust prevention during manufacture oil is sealed up for safekeeping with oil and the dual-purpose wet goods of lubricating and antirust.Generally be: 3～15% with reference to consumption.The highly purified solid lubrication powder of molybdenumdisulphide has anti-friction wear-resistant, and is anti-oxidant, with the metallic surface splendid adhesivity arranged, and can bear high pressure, and operating temperature range is wide.The beautiful light of molybdenumdisulphide tool look has silver grey pool, with graphite the laminate structure of hexagonal is arranged equally, and its crystal is sulphur, molybdenum, three atomic building thin layer elements of sulphur.The coefficient of sliding friction between sheet and sheet can hang down to 0.04, and all more stable to heat or chemistry.Fusing point is more than 1400 ℃, resistance to pressure 2750MPa, and about 270,000 normal atmosphere, low temperature-180 is ℃ lubricated good.Because the character of molybdenumdisulphide physics will not be combined into bigger particle each other, behind the formation molybdenumdisulphide plated film, lubricating oil only plays the effect of molybdenumdisulphide carrier.Before forming the molybdenumdisulphide plated film, molybdenumdisulphide suspends therein, and its lower frictional coefficient has further strengthened the performance of lubricating oil.

Sulfur fluoride plays the friction amendment for boric acid fat amine salt, as long as add a little, nanometer particle can machine oil be a carrier just, is activated under the effect of heat and pressure, infiltrates metallic surface, filling chink and pit.Time is of a specified duration more, and metallic surface is smooth more firm more, and frictional force reduces more than 75%, this smooth firm top layer, and making resistance to wears renders a service lastingly.The many alcohol of glucosides wherein play the structure amendment.
