Abstract
The invention relates to a pocket-type chain wheel () for link chains (), in particular round or profile steel chains. A circumferential surface () of said pocket-type chain wheel is provided with pockets () having alternately different shapes in the circumferential direction (U) and extending radially into the pocket-type chain wheel. In order to diminish noise generation in operation, reduce vibrations generated during operation and simultaneously cut production costs, the present invention discloses that the pocket-type chain wheel () is produced in one piece from a fiber-reinforced plastic by means of an injection molding process. Preferably, a main fiber direction () extends in a central area between the pockets () and a hub () in the radial direction.
