External vibrator with unbalanced weight and weight fixture constructed so centre of gravity of weight can be adjusted in radial direction, to be used in machine for loosening, compacting, or cleaning

摘要

Outer vibrator is attachable to mechanism to be actuated by external vibrations. It contains rotary, motor driven shaft (1) with inserted unbalanced weight (2), coupled non-rotatably to shaft by releasable fastener. Unbalanced weight and its fastener to shaft are so designed that gravity centre of unbalanced weight is displaceable radially, pref. using adjustable displacement mechanism. Unbalanced weight contains shaft retainer (3), while weight motion is limited by radial path limiter(s) (5).
