Abstract
The present invention discloses an opening type rotor engine bearing lubricating grease composition, wherein 50% by mass of a pentaerythritol ester and 50% by mass of metallocene PAO (full-synthetic base oil) are compounded to serve as a base oil, and a variety of additives including a thickener, an antioxidant, a rust inhibitor, an extreme pressure agent, an anti-wear agent, an anti-metal fatigue agent, a metal deactivator, an adhesive, a friction modifier, an anti-oxidation preservative and a reinforcing agent are matched. The lubricant composition of the present invention has characteristics of excellent lubrication, sealing property, friction reducing, bearing property, rust resistance, water resistance, dust resistance, shear resistance, throwing resistance, low noise, and wide temperature use range.
Description
Technical field
The invention belongs to lubricating grease field, particularly open rotor motor bearing grease composition.
Background technology
Because open rotor motor bearing mostly adopts spot contact bearing and ball bearing, its use temperature scope required is-54 DEG C ~ 180 DEG C, and short-term can reach 270 DEG C.And there is good supporting capacity, wear-resistant, antifriction, waterproof, antirust, dust-proof, sealing, noise reduction, oilness and anti-ly fall the ability of getting rid of.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of have excellent lubrication, sealing, anti-attrition, carrying, antirust, waterproof and dustproof, anti-shearing, anti-fall get rid of, the open rotor motor bearing grease composition of low noise properties and wide temperature use range.
The present invention adopts following technical scheme to solve the problems of the technologies described above:
Open rotor motor bearing grease composition, adopt the pentaerythritol ester of mass ratio 50% and the metallocene PAO (complete synthesis base oil) of 50% to be complex as base oil, coordinate multiple additives, its each component and mass percent thereof are:
| Component | Mass percent content |
| Base oil | Surplus |
| Viscosifying agent | 17％～19％ |
| Oxidation inhibitor | 0.6％～1％ |
| Rust-preventive agent | 0.1％～1％ |
| Extreme pressure agent | 2％～4％ |
| Anti-wear agent | 2％～5％ |
| The tired agent of anti-metal | 0.3％～1％ |
| Metal passivator | 0.3％～0.6％ |
| Adhesive agent | 2％～4％ |
| Friction improver | 3％～4％ |
| Antioxidant preservative | 0.3％～1％ |
| Strengthening agent | 1％～2％ |
Viscosifying agent is ditane-4, the 4 '-vulcabond of mass ratio 33%, the hexahydroaniline of 33% and 34% 4,4 '-benzidine compound.
Oxidation inhibitor is the phenyl-a-naphthylamine of mass ratio 50% and the N-acyl group-P-amino-phenol compound of 50%.
Rust-preventive agent is alkylphenol-formaldehyde-amine condenses Mannich alkali.Extreme pressure agent is boronation phosphoric acid ester.
Anti-wear agent is tritolyl phosphate T306.The tired agent of anti-metal is aryl boric acid.
Metal passivation is 124 Triazole derivative T551.Adhesive agent is polyisobutene T603D.
Friction improver is phosphoric acid ester.Antioxidant preservative is second, n-butyl dithiocarbamate molybdenum;
Strengthening agent is thiophosphoric acid phenyl ester T309.
Remarkable advantage of the present invention is: have excellent lubrication, sealing, anti-attrition, carrying, antirust, waterproof and dustproof, anti-shearing, anti-fall get rid of, low noise properties and wide temperature use range.
