VIBRATOR

摘要

The machine proposed has a vibrating plate (1) with unbalanced shafts (W1 to W4) mounted in pairs in it. Each shaft (W1 a W4) is individually driven by a motor (M1 to M4) which runs at a given speed; in synchronization with the other motors. Each shaft (W1 to W4) is fitted with an eccentrically disposed body (U1 to U4). Each motor (M1 to M4) can be controlled, with angular synchronization; by an electronic control unit in such a way that the speed of rotation of the shafts (W1 to W4) can be changed for a short period to alter the vibration frequency; and the speed of rotation of at least one of the two shafts, (W1 to W4) in each pair can be changed for a short period to alter the angular positions of the eccentrically disposed bodies (U1 to U4) with respect to each other.
