Abstract
A vibrator roller frame for supporting a vibrator roller on a horizontal axis of rotation and for transferring static and dynamic forces, comprises, a closed annular one-piece frame member, preferably made of cast steel, having side, end and corner parts, connected to the vibrator roller and annularly surrounding it. The side, end and corner parts are shaped in accordance with the static or dynamic forces they will receive. The corner parts have inside and outside relatively large radii of curvature and connect the side and end parts. The side and end parts have increasing width from a median axis toward the corner portions.
Claims6
A vibrator roller assembly and frame comprising a vibrator roller with a horizontal axis of rotation and an unbalance generator, a closed angular one-piece vibrator roller frame member having a pair of side portions, a pair of end portions and four corner portions connected between said side portions and said end portions respectively, said axis of said vibrator roller connected between said end portions so that static and dynamic forces are transferred from said vibrator roller to said frame member, said four corner portions being internally and externally rounded, said side portions having increasing widths from a median axis of said frame extending perpendicularly to said axis of rotation, said end portions having increasing widths from said axis of rotation, and from the median and horizontal axes to each corner portion, each side and end portion being trapezoidal in shape.
