Abstract

A vibrating screen supported by springs and vibrated via rotating gear sets. The gears are provided with off center weights synchronized to produce angularly directed vibration for moving the material from end to end on the screen. The gears are lubricated with a bath of low viscosity lubricant which is vibrated to form lubricant spikes that extend into the path of the weights to be propelled by the weights into the gears. The weights are substantially crescent shaped at their leading end to avoid hammer like impact of the lubricant and to thereby reduce heat generation.
