ABSTRACT:
In a pocket chain wheel having two groups of pockets (1) for chain links (5) passing the wheel at a tilt, said groups of pockets being arranged side by side in a view perpendicular to the wheel axis (3), the bases (2) of the pockets (1) are shaped such that those legs (4) of the chain links (5) which face the wheel axis (3) are supported, within the pockets (1), only in the curved regions of the transition of the nose ends (6) of the chain links (5) into their legs (4) respectively facing the wheel axis (3). In this way, the stress upon those legs (4) of the chain links which face the wheel axis (3) is significantly relieved and an increase achieved in the service life of said chain links.
