FIELD: mechanical engineering. SUBSTANCE: proposed roller support relates to transport mechanical engineering and can be used in pipe conveyor belts intended for moving dust-producing bulk materials. The support comprises n rollers installed on a common base around a belt rolled into a pipe, the axes whereof are perpendicular to the radius of the pipe and located in a plane perpendicular to the axis of the pipe. Each of the n-1 rollers of the support is made in the form of right and inverted truncated cones interconnected by the smaller-diameter ends, and the nth roller, placed above the joint of the edges of the belt, is made in the form of right and inverted truncated cones facing each other with the smaller-diameter ends and connected by a cylindrical insert, whereon a cylindrical sleeve is installed, configured to rotate relative to the insert. EFFECT: more uniform distribution of the load retaining the belt in the rolled state than in the analogue, leading to a reduction in the wear of said belt and an increase in the longevity of the conveyor. 1 cl, 3 dwg.
