Description
The present invention relates to urea-based lubricating grease composition and the transmission mechanism that contains said composition.After so-called oil crisis took place, oil price was risen sharply, influenced by this, in each industrial circle, the idea that economizes on resources with save energy was arranged all always.
In automotive industry, developed the micro universal automobile, increased the automobile of many employing homokinetic joints (this paper is called for short CVJ).In addition, CVJ also is used for 4 wheel drive vehicles and the four-wheel type automobile that independently suspends, and its demand is also in continuous growth.CVJ claims constant-speed universal joint again, is a kind ofly can keep constant angular velocity and the rotating joint of transmission of torque, has dissimilar according to various uses.Become when more small-sized when automobile reaches higher-wattage and fair speed and CVJ itself, the used lubricant of CVJ will stand severe condition, therefore just requires lubricating grease can reduce the friction and wear of slide unit.In addition, CVJ need load onto sealing rubber cover and reveal and avoid the impurity of outside and the intrusion of water to prevent lubricating grease.About this type of material, generally use chloroprene rubber, vibrin also often adopts.
The lubricating grease of low friction and excellent in wear resistance can suppress car body starting and quicken and travel during the vibration that produces and noise and, because its temperature retarding effect, can improve the weather resistance of rubber coating.But, if temperature rise is too high, then can impel the degraded of the aging and lubricant of rubber coating, greatly shorten the life-span of CVJ.
On the other hand, in Iron And Steel Industry, further develop the mechanical means of operate continuously.Along with technological revolution, improving the quality of products, improving throughput and guaranteeing that the requirement of aspects such as reliability of equipment is stronger.Because the used lubricating grease of these mechanical means is in the rough environment, promptly high temperature, contact, have probably the intrusion of some impurity such as iron scale with water, and can continuously under severe condition, work round the clock, so lubricating condition is very harsh.This just requires lubricating grease that fabulous anti-closure is arranged, and can reduce friction and wear and tear, and to prolong the life-span of machine part, avoids catastrophic failure as far as possible.In addition, the desire lubricating component of industrial machinery, lathe etc. stands bigger friction and excessive abrasion can cause machine, precision to reduce, and has to change machine part.As mentioned above, reduce friction and to avoid wearing and tearing are free-revving engines of the present invention.
Therefore, in above-mentioned desire lubricating component, adopt lithium soap grease traditionally, used sulfur-based compound such as sulfurized fatty and oil, olefine sulfide etc., lead naphthenate, phosphorodithioic acid metal-salt, dithiocarbamic acid metal-salt based additive etc.Recently more employing thermotolerances are better than the complex lithium grease and the urea-base grease of lithium soap grease.
Under this form, as one of prior art typical case's representative, United States Patent (USP) NO.4,514,312 disclose a kind of lubricating grease that uses the arylamine phosphate ester salt of sulfur-bearing not as organic additive in urea-base grease.In addition, United States Patent (USP) NO.4,840,740 disclose a kind of lubricating grease that comprises urea-base grease, organic molybdenum and zinc dithiophosphate.Japanese patent laid-open publication gazette (JP-B) NO.04-34590 (1992) discloses and has a kind ofly comprised that it is the urea-base grease of basal component that sulphur phosphorus base stage is pressed additive, described additive comprises: 1) sulfuration molybdenum dialkyldithiocarbamacompositions and 2) select a kind of in following one group of material or two or multiple composition: sulfurized fatty and oil, olefine sulfide, Tritolyl Phosphate, phosphorodithioic acid trialkyl ester and zinc dithiophosphate dialkyl.
Although some lubricating grease in the prior art has the effect that reduces friction and wear, do not make us very satisfied.And, also have the shortcoming that makes the seal cartridge deterioration under the high temperature.For example arylamine phosphate ester salt and lead naphthenate can make the vibrin degraded, and sulfurized fatty and oil can make the chloroprene rubber severely degrade, and olefine sulfide can make chloroprene rubber and the two severely degrade of vibrin.
In addition, in other prior arts, Japanese Unexamined Patent Publication No (JP-A) 08-157859 (1996) discloses a kind of technology of using molybdenum dialkyldithiocarbamacompositions and triphenyl-thiophosphate as additive, and the Trilithium phosphate that Japanese Unexamined Patent Publication No (JP-A) 62-2275197 (1987) discloses a kind of 12-of use hydroxy fatty acid lithium soap, formed by the phosphoric acid ester such as triphenylphosphate or trimethyl phosphite 99 is as the technology of thickening material.In addition, Japanese Unexamined Patent Publication No (JP-A) 03-231993 (1991) discloses a kind of lubricating grease that comprises phosphoric acid ester oil in carbamide compound.
