ABSTRACT:
A mine working machine employs a main drive transmission with a vertical driven output shaft carrying a gearwheel which can be interchanged with a chain wheel for effecting a chain drive. For a chainless drive, an auxiliary transmission with a housing covering the gearwheel is attached to the machine body or the housing of the main drive transmission. The auxiliary transmission employs rotatable upstanding shafts located at the goaf side of the machine and in the auxiliary housing. The shafts carry gearwheels at their upper ends meshing with the driven gear wheel and pinions at their lower ends meshing with a multi-part rack extending along the path of movement of the machine.
