How to Adjust the Eccentric Weight on Cleveland Vibrator

The rotary electric vibrators are designed with two sets of weights mounted on each end of the motor’s shaft (see the cutaway photo below for the basic design). These weights become the “unbalanced” mass that is used to generate vibratory force as the vibrator rotates.

W. Brian Rowe DSc, FIMechE, in Hydrostatic, Aerostatic and Hybrid Bearing Design, 2012. Inter-Recess Flow and Bridge Angle. For an eccentric shaft, each recess pressure is different, as illustrated in Figure 1.3.Differences in recess pressures cause circumferential flow from one recess to another. Circumferential flow reduces bearing load support and also reduces film stiffness, particularly

Mechanical vibration Eccentric force vibration

Dec 05, 2017 2. Eccentric Force Vibration The presence of an eccentric or unbalanced mass in a rotating disc causes vibration, which may be acceptable up to a certain level. All rotors have some eccentricity. Eccentricity is present when geometrical center of the rotor and the mass center do not coincide along their length. 3.
