  • Injection-molded pocket-type chain wheel made of fiber-reinforced plastic
    Patent number: 9512913
    Abstract: The invention relates to a pocket-type chain wheel (1) for link chains (22), in particular round or profile steel chains. A circumferential surface (2) of said pocket-type chain wheel is provided with pockets (3, 4) 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 (1) is produced in one piece from a fiber-reinforced plastic by means of an injection molding process. Preferably, a main fiber direction (30) extends in a central area between the pockets (3, 4) and a hub (8) in the radial direction.
