Khomenko V. The Substantiation Of Design Data Of Planetary Bit Unaccented Action.

Regularity of deterioration in pair "planetary bit-rock". The substantiation of design data of planetary bits of shock-free operating having a high wear resistance. An all-up method of studies, treating of outcomes on a computer; the standard labware. For the first time: is showed, that, operating coefficient of gas bypassing concerning working face and hole walls, the decrease of deterioration of planetary bits of shock-free operating is reached; the mathematical dependence for definition of a profile of butt end of the satellite of an planetary bit of shock-free operating is proposed, which one provides even deterioration of all members, shattering soil. The planetary bit, made pursuant to the designed method of application, is tested under production conditions. Mining.
