ABSTRACT:
A sprocket wheel arrangement adopted particularly for drives in mining machines as, for example, push-plate conveyors and mining equipment. The number of teeth on the sprocket wheel is smaller than the number of seats between the working surfaces of the teeth and cooperating with chain links passing over the sprocket wheel. The seats are open from one side, and are provided with retaining walls only from the side of the teeth. The planes of bottom lands of adjacent seats intersect and form, thereby, an edge. The sprocket wheel arrangement may be used in driving systems of both coil chains and fish-plate chains.
