"The selection of a water-lubricated solution for the lower
guide bearing instead of the more traditional oil-lubricated design allowed the bearing to be cooled and lubricated with the same river water that is powering the Voith turbine."
Vibration inbearings was measured using industrial accelerometers at positions [B.sub.1] and [B.sub.2] in the
guide bearing nearest to impellerrunner in radial direction.
Thanks to its levitation there is no direct contact between the female rotating bearing and the stationary male
guide bearing. Drive is provided by a motor mounted externally and operated via a frequency converter.
* Sand the edge of boards before routing them so the
guide bearing will ride on a smooth surface.
The patent-pending design of the 8-winged Ultra Clean Mixer causes the impeller to levitate so there is no direct contact between the impeller and the stationary
guide bearing. This design creates less friction which reduces wear on the bearings, reduces particle generation for a cleaner process, and allows the mixer to run in excess of 750 rpm.
Furthermore, the new very high precision
guide bearing, used for shifting the knives and counterknives, assures extreme accuracy in positioning with minimum tolerance and at the same time, is completely unaffected by dust.
Installation and operation largely determine the service life of a mast
guide bearing. Lift truck mechanics should follow the truck manufacturer's installation instructions carefully, taking special care not to damage bearing seals.
