Object of research -tread of connection of mountain machines. The purpose of research - increase of reliability of mountain machines, development of probablis methods of an evaluation of strength tread of connection. Methods of research and the instrumentation - theoretical, experimental researches, in particular, is polarizable - optical by methods. Theoretical outcomes and novelty - offered ways of redistribution of a load between orbits of a thread, evaluation of a pliability tread of detailses; a method of calculation tread of connections of mountain machines. The practical outcomes and novelty - developed designs tread of connections of mountain machines with increased uniform of distribution of a load between orbits, engineering technique of their calculation, in which are taken into account changes of a pliability of a thread. Subject and degree of introduction - "Technique of calculation tread of connections with improved by distribution of a load between orbits at a constant and variable load" TOC "Research Industrial Institute Mineof Engineering c. Curved Horn" and TOC " Tube a Plant c. Curved Horn" КОNSTAR ". Efficiency of introduction - increase of a reserve of fatigue power tread of connections of mountain machines on 6-23%. An orb of use - mountain industry
