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

摘要

A vibratory device comprises a rotor and an eccentric weight. The eccentric weight is mounted to the shaft and has a center of mass that is offset from the shaft axis. The vibratory device is 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 is 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.

1. A vibratory device comprising:
a rotor having a shaft and a rotation limiter, the shaft having a shaft axis about which the rotor is configured to rotate; a first eccentric weight pivotally mounted to the shaft, the first eccentric weight having a center of mass that is offset from the shaft axis, the first eccentric weight comprising a rotation limiter that cooperates with the rotation limiter of the rotor in a manner such that the eccentric weight is able to pivot about the shaft axis relative to the shaft only through an arc of rotation that is less than 360 degrees.
