ABSTRACT:
This invention pertains to induced vibration and the dampening of these vibrations in the motor means. Vibration induced by rotating a shaft having eccentric weight thereon has been used to produce all kinds of shaking apparatus including large car shakers in which the induced force may be as much as eight thousand two hundred pounds. These vibrations can be as much as five thousand six hundred vibrations per minute and can be used for huge bins and hoppers in which the capacity may be as much as one hundred fifty thousand pounds. Vibrators using air, electric or hydraulic motors can be tuned or adjusted to provide the desired results. Most of these vibrators using a tuned motor may be temporarily or permanently attached. Motor driven vibrators, as far as is known, transmits the vibrational force into the shaft of the motor. Said motors, which are usually standard off-the-shelf units have their rotor bearings designed for rotary motion rather than combined with or added vibratory force. This added vibratory force reduces the life expectancy of these motor bearings. This invention employs a rubber dampener and coupling device used between the motor output shaft and the support shaft carrying at least one eccentric weight. This resilient connector substantially eliminates all vibration transfer in the shafts. A vibration dampening apparatus device is also provided to prevent transmission of vibration forces from the independent housing to the motor housing.
