Zamota T. The optimization of the technological factors of rings' sided electrochemical- mechanical running in (grinding in) of piston surfaces in the connections of bush-rings during repair of tractors and combines' engines.

Object of research - technological process of macrogeometrical running in of a piston ring to a mirror of the sleeve of the cylinder. The purpose of a research - to install optimum modes running in of a lateral area of piston rings. Methods and Means of a research - methods of mechanic-mathematical modelling, multifactor planning of experiment. Theoretical outcomes and the novelty - is obtained mathematical. The description of a radial gleam between a ring and sleeve, the formula of a velocity of a diminution of a gleam is introduced, the method of operational development of piston rings is developed new, the best value of technology factors ECMR(G) Practical outcomes and novelty - practical Methods of an evaluation of gleams between a ring and sleeve, is established optimum combinations of the factors running in of rings, the new method of operational development of rings is developed, the improved technology is introduced into production. A degree of introduction - the positions are discussed on 11 conferences, are published in 10 works and are introduced in high school and into production. An orb of use - Repai
