Description
Invenţia se referă la lichidele de ungere şi răcire utilizate la prelucrarea pieselor din oţel, şi anume la un lichid de ungere şi răcire pentru deformarea plastică de suprafaţă a angrenajelor de oţel. The invention relates to lubricating and cooling liquids used in the processing of steel parts, namely to a lubricating and cooling liquid for the surface plastic deformation of steel gears.
Este cunoscut lichidul de ungere şi răcire, care conţine în % mas.: clorură de cupru 4,0…10,0, grafit coloidal 2,0…15,0, acetamidă 5,0…10,0, uree 0,5…1,0, acid stearic 0,5…1,0, apă 5,0…25,0, pulbere fin dispersată de cupru 3…5, precum şi glicerină restul. Acest lichid de ungere şi răcire permite de a depune o acoperire care conţine cupru la deformarea plastică de suprafaţă, în urma schimbului de ioni la contactare, prin deplasarea ionilor din soluţie pe suprafaţa piesei [1]. The lubricating and cooling liquid is known, which contains in wt.%: copper chloride 4.0…10.0, colloidal graphite 2.0…15.0, acetamide 5.0…10.0, urea 0.5…1.0, stearic acid 0.5…1.0, water 5.0…25.0, finely dispersed copper powder 3…5, as well as glycerin the rest. This lubricating and cooling liquid allows to deposit a coating containing copper upon plastic deformation of the surface, following the exchange of ions upon contact, by the displacement of ions from the solution onto the surface of the part [1].
Dezavantajul acestui lichid de ungere şi răcire este faptul că stratul de cupru depus pe suprafaţa prelucrată reprezintă în sine un liant pentru celelalte componente ale lichidului de răcire şi ungere pe suprafaţa piesei la frecare-alunecare. Însă acţiunea acestor componente asupra liantului este efectivă doar dacă stratul de cupru este destul de poros. The disadvantage of this lubricating and cooling fluid is that the copper layer deposited on the machined surface itself represents a binder for the other components of the cooling and lubricating fluid on the surface of the part during friction-sliding. However, the action of these components on the binder is effective only if the copper layer is quite porous.
Pe suprafaţa angrenajelor stratul de cupru obţinut este dens şi uniform. Componentele lichidului de ungere şi răcire pe o astfel de suprafaţă a cuprului au o aderenţă insuficientă, ce duce la un consum sporit de lichid de ungere şi răcire şi micşorează eficacitatea acestuia. The resulting copper layer on the gear surface is dense and uniform. The components of the lubricating and cooling fluid on such a copper surface have insufficient adhesion, which leads to increased consumption of lubricating and cooling fluid and reduces its effectiveness.
Cea mai apropiată soluţie este lichidul de ungere şi răcire, care conţine în % mas.: clorură de cupru 4,0…10,0, grafit coloidal 2,0…15,0, acetamidă 5,0…10,0, uree 0,5…1,0, acid stearic 0,5…1,0, apă 5,0…25,0, pulbere fin dispersată de nichel 5…10, precum şi glicerină restul [2]. The closest solution is the lubricating and cooling liquid, which contains in wt.%: copper chloride 4.0…10.0, colloidal graphite 2.0…15.0, acetamide 5.0…10.0, urea 0.5…1.0, stearic acid 0.5…1.0, water 5.0…25.0, finely dispersed nickel powder 5…10, as well as glycerin the rest [2].
Acest lichid permite de a obţine acoperiri prin aplicarea acestuia pe suprafeţele prelucrate, însă utilizarea în practică a lui arată că rezistenţa la uzură şi calitatea suprafeţelor prelucrate depind de aderenţa stratului depus pe piese şi grosimea acestuia. Cu creşterea grosimii acoperirii, aderenţa se micşorează, cauzând uzura sporită a sculei de netezire, în consecinţă durata de funcţionare a transmisiei (a cuplelor cinematice, ansamblurilor de frecare) devine mai mică. This liquid allows to obtain coatings by applying it to the machined surfaces, but its practical use shows that the wear resistance and quality of the machined surfaces depend on the adhesion of the layer deposited on the parts and its thickness. With increasing thickness of the coating, the adhesion decreases, causing increased wear of the smoothing tool, consequently the service life of the transmission (kinematic couplings, friction assemblies) becomes shorter.
Utilizarea acestuia în cuple este ineficientă. Acţiunea acestor componente faţă de cele de legătură (sporirea adeziunii de stratul cuprat) este efectivă doar dacă stratul de cupru depus este destul de poros. Its use in couplings is inefficient. The action of these components on the bonding ones (increasing the adhesion to the copper layer) is effective only if the deposited copper layer is quite porous.
Problema pe care o rezolvă prezenta invenţie constă în extinderea posibilităţilor tehnologice prin netezirea dinţilor angrenajelor şi acoperirea simultană de protecţie a acestora, sporirea randamentului şi a rezistenţei la uzură a transmisiei. The problem solved by the present invention consists in expanding technological possibilities by smoothing the gear teeth and simultaneously coating them with protective coating, increasing the efficiency and wear resistance of the transmission.
Lichidul de ungere şi răcire pentru deformarea plastică de suprafaţă a angrenajelor de oţel conţine clorură de cupru, grafit fluorurat, acetamidă, uree, acid stearic, apă, pulbere fin dispersată de cupru şi nichel, precum şi glicerină în următorul raport al componentelor, % mas.: The lubricating and cooling liquid for surface plastic deformation of steel gears contains copper chloride, fluorinated graphite, acetamide, urea, stearic acid, water, finely dispersed copper and nickel powder, as well as glycerin in the following component ratio, % wt.:
clorură de cupru 3…12 grafit fluorurat 2…16 acetamidă 4…10 uree 0,25…1,0 acid stearic 0,5…1,0 apă 2,5…25,0 pulbere fin dispersată de cupru şi nichel, în raport de 1:1 1…6 glicerină restul.copper chloride 3…12 fluorinated graphite 2…16 acetamide 4…10 urea 0.25…1.0 stearic acid 0.5…1.0 water 2.5…25.0 finely dispersed powder of copper and nickel, in a ratio of 1:1 1…6 glycerin the rest.
Rezultatul constă în extinderea posibilităţilor tehnologice prin netezirea dinţilor angrenajelor şi acoperirea simultană de protecţie a acestora, sporirea randamentului şi a rezistenţei la uzură a transmisiei. The result is the expansion of technological possibilities by smoothing the gear teeth and simultaneously coating them with protective coating, increasing the efficiency and wear resistance of the transmission.
Transmisiile dinţate au o destinaţie foarte largă, sunt de mai multe tipuri şi îndeplinesc diferite funcţii, de exemplu cinematice (pentru a spori momentul de torsiune). Din această cauză ele sunt executate din diferite materiale, aliaje, oţeluri de o gamă foarte largă, fontă şi pulberi metalice. Netezirea angrenajelor se face pentru a durifica stratul superficial, a micşora rugozitatea, a spori rezistenţa la uzură şi randamentul. Gear transmissions have a very wide purpose, they are of several types and perform different functions, for example kinematic (to increase the torque). For this reason they are made of different materials, alloys, a very wide range of steels, cast iron and metal powders. Gear smoothing is done to harden the surface layer, reduce roughness, increase wear resistance and efficiency.
Prin utilizarea lichidului de ungere şi răcire se protejează angrenajul roţii dinţate (mai ales în transmisii deschise) şi se netezesc fisurile care se formează în timpul prelucrării. The use of lubricating and cooling fluid protects the gear wheel (especially in open transmissions) and smoothes out cracks that form during machining.
În procesul netezirii angrenajelor, scula în timpul contactării cu semifabricatul se află în condiţii mai complicate faţă de alte suprafeţe de generare. Adică scula la netezirea dintelui la baza acestuia se află în condiţii dificile, arcul de contact al dintelui cu scula este mai mare, forţele sunt mai mari, creşte temperatura din cauza accesului limitat al lichidului de ungere şi răcire în zona de lucru. În partea de mijloc a dintelui condiţiile de prelucrare sunt normale, la vârful dintelui scula trece fără efort, condiţiile de prelucrare sunt bune. In the process of gear honing, the tool during contact with the workpiece is in more complicated conditions than other generating surfaces. That is, the tool when honing the tooth at its base is in difficult conditions, the contact arc of the tooth with the tool is larger, the forces are greater, the temperature increases due to the limited access of the lubricating and cooling liquid to the working area. In the middle part of the tooth, the machining conditions are normal, at the tip of the tooth the tool passes without effort, the machining conditions are good.
Limitele raportului componentelor din lichidul de ungere şi răcire propus este mai larg datorită condiţiilor mai dure de netezire a angrenajelor. The limits of the ratio of components in the proposed lubricating and cooling fluid are wider due to the harsher conditions of gear smoothing.
Utilizarea grafitului fluorurat este un avantaj pentru lichidul de ungere şi răcire. Grafitul coloidal este un bun component în lichidele de ungere şi răcire utilizat în prelucrări prin forjare, matriţare, pentru tragerea la rece a diferitor profile din aluminiu, alamă şi alte aliaje cu scopul de a obţine o peliculă uscată de grafit pe matriţe şi dornuri. Datorită structurii sale plastice, protejează suprafeţele care se află în frecare şi micşorează uzura lor. Grafitul coloidal dizolvat în apă şi alte componente utilizate în lichidele de ungere şi răcire, intrând în contact cu suprafaţa prelucrată, devine suprasaturat, absorbind particule minerale şi cade în baie, unde se stochează lichidul de ungere şi răcire şi nu mai participă în proces, adică grafitul coloidal este mai puţin stabil în apă faţă de grafitul fluorurat. Grafitul fluorurat are proprietăţi mai bune de lubrifiere decât grafitul coloidal, este mai stabil în diferite medii (temperaturi ridicate, vacuum, apă). În aceste medii coeficientul de frecare a grafitului coloidal scade. Utilizarea grafitului fluorurat sporeşte randamentul procesului de netezire a angrenajelor. The use of fluorinated graphite is an advantage for the lubricating and cooling fluid. Colloidal graphite is a good component in lubricating and cooling fluids used in forging, die-casting, cold drawing of various profiles made of aluminum, brass and other alloys in order to obtain a dry graphite film on dies and mandrels. Due to its plastic structure, it protects surfaces that are in friction and reduces their wear. Colloidal graphite dissolved in water and other components used in lubricating and cooling fluids, coming into contact with the processed surface, becomes supersaturated, absorbing mineral particles and falls into the bath, where the lubricating and cooling fluid is stored and no longer participates in the process, i.e. colloidal graphite is less stable in water than fluorinated graphite. Fluorinated graphite has better lubricating properties than colloidal graphite, it is more stable in different environments (high temperatures, vacuum, water). In these environments the friction coefficient of colloidal graphite decreases. The use of fluorinated graphite increases the efficiency of the gear smoothing process.

În zona de frecare s-au realizat condiţii de ungere limită. Uzura probelor se determină prin profilarea grafică discretă a suprafeţei de frecare prin metoda standard. The wear resistance was determined on a reciprocating grinding machine. The tests were carried out at static loads: the specific pressure was 25 MPa, at a normal force of 400 N and at 1400 double strokes/min. In the friction zone, boundary lubrication conditions were achieved. The wear of the samples is determined by discrete graphic profiling of the friction surface using the standard method.
Rezistenţa la gripare se determină la tribometru, prin metoda standard în condiţiile frecării limită: presiunea specifică de 7 MPa, viteza de rotire 8 m/min. The resistance to seizure is determined on a tribometer, by the standard method under the conditions of limit friction: specific pressure of 7 MPa, rotation speed 8 m/min.
