摘要

Improvements in the transport devices by pulleys with eccentric support and planetary movement, characterized in that they comprise a suspension plate whose shape conforms to the particular requirements of each application case, and carrying riveted in a conically embossed print in its central part, a annular seat secured to a vertical pivot with a conical seat at its free end and a collete turned at its average height; a half hollow hemispherical hollow ball joint cast in one piece with a cylindrical vertical bearing with which it is eccentrically coupled to the vertical pivot and adopting the plane that forms its circular edge a certain declination of the vertical; its inner central part is fused with reinforcement and is integral with a diametrical axis that runs at a right angle with respect to said plane of its circular edge, that is, with the same angular deviation from the horizontal, which has said plane from to vertical ; it also has, in internal reinforcements, a key-pin that couples both this half-ball joint to the vertical pivot, and the second half-ball joint to the axis of the first half-ball joint. A second hollow half-socket sunk with internal radial reinforcements and, at its center, with a bearing bushing that adapts to the axis of the first half-ball on which it freely rotates, and provided with a circular retaining cylinder by the key-pin; the part of its greater diameter forms a rolling path of greater diametrical extension than the remaining parts of both half-joints and covering or overlapping the free edge of said rolling path, the outer edge of the first half-ball around which it freely rotates.
