ABSTRACT:
Sprocket wheels for use in chain conveyors, for instance, are preferably of a divisible construction so as to enable each wheel to be removed from the shaft separately. Also, on the basis of considerations of hygiene, the outer side surface of such a wheel is preferably entirely flat when used in the food or beverage industry. Existing divisible wheels are either flat on the outside, but expensive, or not flat and cheap because they are made by injection molding. The synthetic sprocket wheel according to the invention is flat and cheap and comprises two wheel halves with axial planes abutting against each other, each wheel half consisting of two interconnected parts, made by injection molding, abutting against each other through a radial side face, with the cavities and ribs necessarily present for the injection molding process being located in the interior of the wheel half.
