Abstract

A plate link chain of the present invention has rocker link elements configured such that the frictional end surfaces have a profile, which deviates from a planar surface in both circumferential and radial orientations. In a preferred embodiment the end surface profiles are defined by radii of predetermined dimensions in the range of 5 to 50 millimeters with the radius formed in the radial plane being larger than the radius formed in the circumferential plane. The radii originate from midpoints, which are located at predetermined distances from the rocking surfaces, to form substantially spherical end surfaces that are either symmetric or asymmetric for selected applications. The substantially spherical end surfaces are designed to reduce the edge transfer forces and tracking error of the rocker link elements and to improve wear characteristics and the stability of frictional engagement of the transmission in operation.
