Jurchishin O. It is elastic-damping performances and prediction of boundaries of use of wide-range collet chuks

The thesis is devoted examination is elastic-damping performances and to prediction of boundaries of use wide-range collet chuks with multiplication for lathes. On the basis of the analysis of achievements of science and technology examination of known constructions wide-mange collet chuks and an existing state of procedures of their examinations is carried out. Theoretical examinations of dynamic system a spindle- collet chuks-detail are carried out, procedures of experimental researches are developed for definition is elastic-damping properties of gripping sockets of different types. Taking into account damping coefficient and model of process of contact interacting of perform the mathematical model of an elastic-system "spindle- collet chuks-detail" is developed for existing and new constructions wide-range-collet chuks. Experimental researches and commercial tests of constructions wide- collet chuks with the refined damping properties are spent. The experiment plot behind four factors is developed and on the basis of experimental data the mathematical model of elastic releases of system collet chuks-detail is gained. The observational measurings of a dynamic- characteristic of damping were spent by definition a natural resonant frequency mounting clamped in a wide-range-collet chuks.
