Повышение износостойкости подшипников качения на основе применения полифункциональных пластических смазок

Аннотация

Subjects of the inquiry: bearing of the swing and new swabbing material on base gudrone of vegetable oils. Aim of the inquiry: development methods theoretical estimation factor, influencing upon wear capability element bearings of the swing and increasing to their wear capability with using designed multifunctional of the plastic lubrificants. Methods of inquiry: used methods comparative analysis result theoretical and experimental studies of the wear-out element bearing of the swing. The results achieved and their novelty: They are received analytical dependencies of the calculation geometric and kinematic parameter, influencing upon of wear element bearing swings and determination of the factor of friction between element of the bearing and abrasive particle; the designed methods of the theoretical estimation to velocities of wear and sizes of the abrasive particles, participating in process wear element bearing of the swing; high wear capability plastic lubrificant is designed on base gudrone of vegetable oils; designed stand for test bearing swings with new constructive decision, allowing value wear capability of the designed lubrificants. Practical value: The new lubrificant is designed on base gudrone of vegetable oils received on base resource local secondary cheese and is determined that he has high efficiency than traditionally applicable lubrificants. Degree of embed and economic affectivity: The Designed lubrificants on base gudrone of vegetable oils passed production test on agricultural machine of SjsC Yakkabag machine-tractor park of Kashkadarya region (the act about introduction result test from april 13, 2010) and excavators ore management «Kalmakir» Almalik blazed-metallurgical combine (the act about result of the production test from august 20, 2010) and have shown that these lubrificants have high wear capability. The designed lubrificants are recommended for broad using in machine and mechanism data enterprise. Using designed swabbing material at usages tractor for 1000 conditional tractors costperformance forms 94 432 thousand sum, made for 834 tractors cost-performance forms 55 544 thousand sum. Sphere of usage: machine-building, tractor-manufacturing, agriculture.
