Abstract

Przedmiotem zgłoszenia jest zębatka bezcięgnowego mechanizmu posuwu górniczego kombajnu ścianowego. Zębatka współpracuje z pionowym kołem zębatym trakowym tworząc bezcięgnowy system posuwu górniczego kombajnu ścianowego. Zębatka składa się z powtarzalnych segmentów, z których każdy ma tylko jeden ząb, przy czym zarys zęba (2) zębatki ma w przekroju poprzecznym kształt zbliżony do trapezu, a zarys flanki zęba jest połączeniem górnej walcowej powierzchni wypukłej (4), dolnej walcowej powierzchni wypukłej (6) oraz łączącej je centralnej powierzchni płaskiej (5). Flanka zęba (2) zębatki wystaje powyżej górnej płaszczyzny ścian bocznych segmentu zębatki.The subject of the application is a rack of the chained mining feed mechanism of a longwall shearer. The rack cooperates with the vertical rack gear wheel, creating a chain-less mine feed system of a longwall shearer. The rack consists of repetitive segments, each of which has only one tooth, the shape of the tooth (2) of the rack having a cross-sectional shape similar to a trapezoid, and the outline of the tooth flank is a combination of the upper cylindrical convex surface (4), the lower cylindrical convex surface (6) and the central flat surface (5) connecting them. The tooth flank (2) of the rack extends above the top plane of the side walls of the rack segment.
