Abstract
A deflecting roller for link chains, for example, round link chains or profiled steel chains, presents, on the periphery, chain pockets for lying chain links. Furthermore, chain pockets for standing chain links are provided. The chain pockets for the standing chain links are separated from each other by teeth. The tooth flank surfaces of the teeth, against which a standing chain link bears under the action of a load, are dimensioned and profiled in a specific way. The dimensioning is carried out so that, up to a certain chain loading, the standing chain link does not bear with its nose against the tooth flank. A contact between the tooth flank surface and the nose of the standing chain link concerned occurs only starting at a certain chain loading.
