Abstract:
1. A belt tracking mechanism for use in a belt conveyor, comprising: a pulley support yoke adapted for at least limited rotational movement within a frame of the conveyor, the pulley support yoke further adapted to support and retain a conveyor pulley; an angular linkage having a first leg and a second leg between which resides a flexure pivot that creates a weak point within the linkage and permits an angular change to occur between the first and second linkage legs, a free end of the second linkage leg coupled to the pulley support yoke; and a single adjustment element coupled to a free end of the first linkage leg at a point away from a pulley support location of the pulley support yoke; wherein, the single adjustment element is adapted such that adjustment thereof will produce a linear displacement of the first angular linkage leg, said linear displacement causing a pivoting in a selected direction of the second linkage leg and the coupled pulley support yoke.
