Аннотация

Subjects of research: springs, methods and technological processes of restoration of cylindrical coil springs used in agricultural, land reclamation and construction machines, tractors, automobiles and manufacturing equipment. Purpose of work: To upgrade the resource recovery technologies of cylindrical coil springs used in agricultural, land reclamation and construction machines, tractors, automobiles and manufacturing equipment. Methods of research: Theoretical studies were performed using the basic tenets of the theory of mechanics, plastic deformation, heat balance and mathematical analysis, and an experimental study in the laboratory, laboratory-production and production conditions, using respectively test and measurement instrument. The results obtained and their novelty: modernized the method and equipments for restoring springs arc derived to determine the dependence of processing modes in view of reducing the elasticity of the springs Practical value: modernized method and arrangement and technological process for restoring springs. Degree of installation and economic effectivity: research and technological process adopted for the implementation of the production process of "TashOR 'and the ICC Yukori Chirchik fog Tashkent region of the association" Uzagromashservis "and the learning process of the Tashkent Institute of Irrigation and Land Reclamation. Cost of restoration of valve springs is 664,73 or the sum of 33% of the cost of a new spring. The expected economic effect of the sum at 6454238 recovery program 5000 units per year. Payback period of investment is 2 years. Field of application: Recommended for specialized repair services associations "Uzagromashservis" and repair shops of machine-tractor parks.
