Abstract
Sposób regeneracji styczno - obrotowych noży kombajnów górniczych polega na tym, że stosuje się podwójne słupkowe ostrza skrawające lub podwójne pierścieniowe ostrza skrawające lub podwójne ostrza pierścieniowe (9), które po wymontowaniu z trzonków noży (13) i uzupełnieniu ubytków zużyciowych elementem kompensującym zużycie ostrza lub pierścieniem kompensującym zużycie ostrza, odwraca się o 180° w układzie przód-tył, po czym osadza się je ponownie w trzonkach noży (13) poprzez twarde lutowanie mosiądzem lutowniczym w postaci krążka lub pierścieniowej podkładki lub przez połączenie gwintowe (10).The method of regeneration of tangential-rotary knives in mining combines is based on the use of double bar cutting blades or double ring cutting blades or double ring blades (9), which, after removing from the handles of the knives (13) and supplementing wear losses with the element compensating the blade wear, or the blade wear compensating ring, is turned by 180 ° in the front-back configuration, and then reseated in the knife handles (13) by brazing with brass soldering in the form of a disc or ring washer or by a threaded connection (10).
