Description
Technical field
The present invention relates to aircraft maintenance professional skill field, specifically a kind of airplane wheel bearing cleaning agent.
Background technology
Airplane wheel bearing is made up of inner ring, retainer, cylindrical roller, belongs to taper roll bearing type.Install and
During dismounting etc. is safeguarded, its structure is not decomposed.Airplane wheel bearing bears larger radial and axial connected load simultaneously, is wheel
The rotation of wheel hub provides accurate guiding, keeps wheel shaft center to fix, and ensures that aircraft is parked, slided and landing safety
One of part.
During aircraft landing, the temperature that wheel bearing is born is up to 100 DEG C or so, therefore, and the maintenance of wheel bearing maintenance is carried
Higher requirement is gone out.
In order to reduce the friction of airplane wheel Bearing inner and wear and tear, prevent from burning viscous, bearing coating lubricating grease is lubricated.Machine
Wheel-bearing grease belongs to synthetic fat, is made up of components such as base oil, thickening agent, additives, intensity is formed on bearing roller high
Lubricating film, bear under larger load, normal temperature that viscosity is big, adhesive force is strong, is difficult to remove cleaning.
Airplane wheel is in brake gear inspection, re-type, and inspects periodically period, is required to dismount it.
It is also one of regular work of aircraft maintenance to dismount wheel, and is both needed to clean wheel bearing in disassembly process every time.
The clean-up performance on bearing roller surface, cleaning quality on the undulating value influences of the vibration values and bear vibration of bearing compared with
Greatly.Though the cleaning of bearing can not directly improve its precision, life-span and its property indices, cleannes will directly affect these
Index, is also the necessary condition that bearing accuracy, life-span and properties are maintained, with the raising required bearing quality,
Bearing cleaning seems more and more important.
The cleaning of airplane wheel bearing, will not only remove bearing grease and impurity, reach clean surface, it is necessary to ensure
Bearing is not caused hydrogen embrittlement etc. to adversely affect by burn into.Therefore, the requirement of harshness is proposed to cleaning agent.
At present, in aircraft maintenance, traditional manual cleaning method is still continued to use in the cleaning of airplane wheel bearing, that is, is adopted
With cleaning gasoline as cleaning agent, cleaning is implemented using the mode for cleaning gasoline immersion, hairbrush is scrubbed.Although cleaning gasoline containing virtue
Hydrocarbon, can dissolve bearing grease, but to there is flash-point low, inflammable, dangerous for cleaning gasoline；And scavenging period length, labor intensity are big
Deficiency.At present, although developed heavy oil cleaning agent, there is universal cleaning action to grease, greasy dirt and its mixed dirt,
Certain application has been obtained in industry cleaning link, due to being developed for airplane wheel bearing cleaning, practice have shown that, it is right
Airplane wheel bearing cleaning speed is slow, time length, effect are poor, it is impossible to cleaning requirement is met, therefore, in airplane wheel bearing cleaning
In be not used widely.
The content of the invention
It is dangerous in order to overcome existing cleaning agent flash-point low；Scavenging period is long, and the deficiency of effect difference, the present invention is proposed
A kind of airplane wheel bearing cleaning agent.
The present invention is made up of surfactant, nonaqueous solvents, auxiliary agent and water；Wherein surfactant, nonaqueous solvents, auxiliary agent
Mass ratio with water is the ︰ 1 of 0.02~0.1 ︰, 0.05~0.15 ︰ 0.02~0.08；Described surfactant is by detergent alkylate
Sodium sulfonate, Tween20 or Tween 40, Vinlub 73 or AEO (AEO-9) and peregal
15 or peregal 20 constitute；Described nonaqueous solvents is made up of ethanol, ethyl acetate, ethylenediamine or ether or n-hexane；It is described
Auxiliary agent be made up of sodium carbonate, sodium ethylene diamine tetracetate or sodium tartrate and sodium gluconate or sodium citrate, the water is goes
Ionized water or distilled water.
In the surfactant, neopelex, Tween 20 or Tween 40, polyoxyethylene mono laurate
The mass ratio of ester or AEO (AEO-9), peregal 15 or peregal 20 is the ︰ 0.6 of 1.0~1.5 ︰ 0.8~1.0
~0.8 ︰ 1.
In the nonaqueous solvents, the mass ratio of ethanol, ethyl acetate, ethylenediamine or ether or n-hexane is 0.6~1.0 ︰
1.0~1.5 ︰ 1.
In the auxiliary agent, the quality of sodium carbonate, sodium ethylene diamine tetracetate or sodium tartrate, sodium gluconate or sodium citrate
Than for the ︰ 1 of 1.0~1.8 ︰ 0.6~0.9.
The solubility parameters for the nonaqueous solvents that the present invention is selected is close with the solubility parameters of wheel bearing grease, meets similar
Mix principle, and dissolving bearing grease, thorough, speed is fast, and cleaning performance is good, efficiency high；Existed from hydrophilic lipophilic balance
Tween 20 or Tween 40, Vinlub 73 or AEO in the range of 12.8 to 16.7
(AEO-9), the proportion of surfactant such as peregal 15 or peregal 20, advantageously forms micella, to lubricating grease formation oil-in-water,
Solubilization is excellent, and emulsifying effectiveness is good；Auxiliary agent can form complex ion, increase the solubility of cleaning agent；The adjustment of auxiliary agent sodium carbonate is clear
The pH value of lotion is to alkalescence, it is to avoid the harm of bearing hydrogen embrittlement；The neopelex of strong detergency and other surface-actives
Agent and additive compound, have preferable herbicide interactions, further lift cleaning effect；Cleaning agent flash-point is high, nontoxic, uses
Safety.
Experiment proves that cleaning agent proposed by the present invention is using safety, to bearing non-hazardous, cleaning efficiency reach 85% with
On, meet cleaning requirement.
