1. An advancing drive assembly for longwall coal shearers. It is characterised in that the housing (1) is divided with internal walls (11, 12) into three chambers. Two of them, namely the dry chamber (2) and the wet chamber (3), are parallel to each other and located transversally with respect to the longitudinal axis (5) of the housing (1). The longitudinal chamber (4) is located at the front of the dry chamber (2) and the wet chamber (3), parallel to the longitudinal axis (5) of the housing (1). The toothed reduction gear between the engine (6) and the advancing gear (7) is divided into at least two modules (8, 9,10). The modules are separate assembly units, connected to each other in series. |
