The results of the comparative analysis of wear process of wheelpairs of electric locomotives VL11 which has passed plasma hardening of ridges of bandages are given. On the basis of methods of the theory of probability and the mathematical statistics after processing of the assembled statistical information of deterioration of a bandage and a ridge the conclusion is drawn on efficiency of application gas-flame hardening the resource before turning of wheel pairs of electric locomotives has increased by 25 %.
Key words: locomotive, wheel pair, bandage, deterioration, hardening, resource

Belousov V. P., Dianova N. G. Improvement of the design formulae to determine sewing needle cross-section

Design formulae for determining sewing needle cross-section are obtained and formulae are improved, by which moment of inertia of the needle cross-section, inertia moment radius of the needle cross-section, needle flexibility and cross-sectional area of the needle eye are determined.
Key words: sewing needle, moment of inertia, cross-section area


Boyko A. V., Puzacheva Ye. I. Microhole electrospark broaching precision

The main fault in micro holes EDM flashing is an error of round form. The reason for this error is that electrodes axis is not parallel to the line feed. Roundness equation was found through research. Also, other errors found: local one-sided cone breaking of micro holes and unilateral lowering the nominal diameter of the hole due to wear of electrode in the processing of blind holes.
Key words: EDM flashing, micro hole, hole roundness, cone breaking, wear of electrode
