CONVEYOR BELT TRACKING MECHANISM AND CONVEYOR EMPLOYING THE SAME

摘要

Exemplary embodiments described herein are directed to conveyor belt tracking mechanisms with a single adjusting element and to conveyors having conveyor belts whose tracking may be adjusted in both directions using such conveyor belt tracking mechanisms. One exemplary conveyor belt tracking mechanism embodiment employs a pulley support yoke coupled to a specialized angular linkage having a linkage flexure pivot that translates linear motion into angular motion.

主权项

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.
