  • AB027 : Eccentric Mass Parameters for Vibration Motors

    Typically we see two different types of eccentric masses on ERMs: Offset Disc – Simply a cylinder with a hole for the shaft, which is offset from the centre of the disc This creates an eccentricity which in turn produces the vibration when rotating about the shaft For an eccentric shaft, each recess pressure is different, as illustrated in Figure 13 Differences in recess pressures cause circumferential flow from one recess to another Circumferential flow reduces bearing load support and also reduces film stiffness, particularly for L / D > 1Eccentric Shaft an overview ScienceDirect TopicsIn the righthand image, the runout is caused by eccentric rotation These factors, and other factors such as bearing clearance and load induced shaft flexure, can combine to produce complex lateral shaft motion during rotation Shaft deflection, runout, vibration, and axial motionChapter D4 Page 2 Contact Kalsi Engineering this handbookHandling shaft deflection, runout, vibration, axial motion
