Abstract

Zespół urabiający jest skonfigurowany do połączenia z bębnem, który może obracać się wokół osi. Zespół urabiający zawiera blok mający powierzchnię prowadzącą oraz powierzchnię wewnętrzną. Powierzchnia wewnętrzna tworzy otwór bloku biegnący wzdłuż osi przechodzącej przez powierzchnię prowadzącą i co najmniej częściowo przez blok. Zespół urabiający zawiera również tuleję (78) mającą trzon tulei z powierzchnią zewnętrzną, kołnierz oraz otwór tulei biegnący przez kołnierz i co najmniej częściowo przez trzon tulei. Podczas montowania tulei w bloku, sprzęgnięcie między powierzchnią zewnętrzną trzpienia tulei a powierzchnią wewnętrzną otworu bloku przechodzi od pasowania na wcisk do pasowania luźnego.The cutting assembly is configured to be coupled to a drum that is rotatable about an axis. The cutting assembly includes a block having a guide surface and an interior surface. The inner surface forms a block opening along an axis passing through the guide surface and at least partially through the block. The cutting assembly also includes a sleeve (78) having a sleeve shank with an outer surface, a collar, and a sleeve bore extending through the collar and at least partially through the sleeve shank. When mounting a bushing to a block, the engagement between the outer surface of the bushing pin and the inner surface of the bore of the block varies from an interference fit to a loose fit.
