Shaft Seals for Rotating Shafts - Vacaero

Aug 13, 2013 · Fig. 1 Stuffing Box with packing rings. On any machine that has a rotating shaft there will be a shaft seal of one type or another. If the machine is a simple electric motor, for example, the seal may be used just to retain the lubricant in the bearings and to prevent dust and dirt from entering the bearing.

ALIGNMENT OF VERTICAL SHAFT HYDROUNITS

On a vertical shaft hydrounit, the thrust bearing supports the entire rotating weight of the unit, as well as any hydraulic down thrust from the turbine. There are typically three types of thrust bearings used in hydroelectric units: the adjustable shoe, the spring loaded bearing, and the self equalizing.

Motion 101: The dynamics of shafts and axles | Machine Design

Motion 101: The dynamics of shafts and axles. As speed increases, centrifugal force exaggerates the eccentricity, pulling outward on the shaft. At critical speed, the shaft resonates, vibrating over or even whirling around the rotation axis, and the displacement amplitude can rapidly become destructive.

Using thrust bearings to support a vertical shaft? - reddit

Nov 10, 2014 · First, analyse your forces on the shaft. Depending on the teeth of your gears, you might get additional axial force or reduce the weight force. (This won't be an issue with straight-cut teeth.) Pure thrust bearings (axial bearings) can take very little radial forces,...

inch of spacer shaft length. For example, a machine running at 1800 RPM with 12 inch of spacer shaft length would allow a maximum offset of: 0.6 mils/inch x 12 inches = 7.2 mils at either coupling at the ends of the spacer shaft. Rigid couplings have no tolerance for misalignment, they should be aligned as accurately as possible.
