Method of Repositioning Bearing Wear in an Industrial Eccentric Weight Vibrator Via Power Inversion and Vibrator Therefore

A vibratory device comprising a rotor and an eccentric weight, the rotor having a shaft, the shaft having a shaft axis about which the rotor is configured to rotate, the eccentric weight being mounted to the shaft and having a center of mass that is offset from the shaft axis, the vibratory device being configured such that the eccentric weight is in a first rotational orientation relative to the shaft and rotates with the shaft when the shaft rotates in a first direction about the shaft axis and such that the eccentric weight is in a second rotational orientation relative to the shaft when the shaft rotates in an opposite second direction about the shaft axis, the vibratory device being further configured such that the eccentric weight automatically transitions from the first rotational orientation to the second rotational orientation when the shaft is switched from rotating in the first direction to rotating in the second direction.

A method of adjusting a vibratory device, the vibratory device comprising a rotor and an eccentric weight, the rotor having a shaft, the shaft having a shaft axis about which the rotor is configured to rotate, the eccentric weight being mounted to the shaft and having a center of mass that is offset from the shaft axis, the vibratory device being configured such that the eccentric weight is in a first rotational orientation relative to the shaft and rotates with the shaft when the shaft rotates in a first direction about the shaft axis and such that the eccentric weight is in a second rotational orientation relative to the shaft when the shaft rotates in an opposite second direction about the shaft axis, the method comprising:

• reversing the direction in which the shaft of the rotor and the eccentric weight rotate about the shaft axis in a manner causing the eccentric weight to move from the first rotational orientation to the second rotational orientation.
