Vibratory Drum Assembly
Vibrator Drum Assembly.
(1) Eccentric weight. (2) Eccentric weight. (3) Drive shaft. (4) Coupling. (5) Vibratory motor.
Vibratory action for the machine occurs at the drum assembly.
Drive shaft (3) is connected to vibratory motor (5) with coupling
(4).
When the operator turns the vibratory system ON, the vibratory
motor causes drive shaft (3), eccentric weights (1) and (2) and
coupling (4) to rotate. The rotation of the eccentric weight
creates the desired vibratory action of the drum assembly.
