CONSISTENT LUBRICANT USED FOR THE ROCK CUTTER DRILLING BITS SEALED BEARING SUPPORTS Russian patent published in 2007 - IPC C10M135/04 C10M133/22 C10M129/74 C10N30/06 

FIELD: mining industry; petroleum industry; natural gas industry; metallurgy industry; production of the consistent lubricant used for the rock cutter drilling bits sealed bearing supports.

SUBSTANCE: the invention may be used in mining, oil, gas and metallurgical industries. The consistent lubricant contains (in mass %): the synthetic oil 3V - 13-22, caroflux - 3-5, the powder of copper phthalocyanine and cobalt phthalocyanine - (1:1) 1.5-2.3, sulfuric additive - 1.3-2.1, the cylinder oil - 52 ( the rest). The sulfuric additive represents the product of telomerization of sulfur and piperyilene. The technical result of the invention is the increased wear resistance of the friction units of the rock cutter drilling bits sealed bearing supports in 3.2 times, the improved low-temperature properties of the consistent lubricant.

EFFECT: the invention ensures the increased wear resistance of the friction units of the rock cutter drilling bits sealed bearing supports - in 3.2 times, the improved low-temperature properties of the consistent lubricant.
