an eccentric shaft is used in the inclined vibrating screen. there is an advantage of using this method of vibration generation over the unbalanced flywheel method first mentioned. the vibration of an unbalanced flywheel is very violent. this causes mechanical failure and structural damage to occur. the four-bearing system greatly reduces this problem.,soil compaction handbook - multiquip,vibratory force uses a mechanism, usually engine-driven, to create a downward force in addition to the machine’s static weight. the vibrating mechanism is usually a rotating eccentric weight or piston/spring combination (in rammers). the compactors deliver a rapid sequence of blows (impacts) to the surface, thereby affecting
