COAL-FIRED POWER plants use gearboxes located on the top of each coal pulverizer to drive the rotating classifier. Rotating classifiers ensure that the coal is of the appropriate size for proper ...

Machine tool spindles serve as the backbone to numerous manufacturing sectors, enabling creation of precision-engineered components with exceptional accuracy. However, there is a persistent problem at ...

Just weeks before the commissioning deadline at a new power plant, problems with one of a pair of steam turbine/generator sets surfaced. Hundreds of thousands of dollars per day in liquidated damages ...

What do clocks, skateboards, and industrial machinery have in common? They all rely on bearings to maintain their smooth rotational movements. However, to achieve reliability, they must be maintained ...

A minor coal train derailment in Virginia in early July prompted Norfolk Southern to rethink the way it responds to problems with overheating bearings, but it’s not clear why the railroad didn’t make ...

The difference between good and bad in the wheel bearing world is a very fine line — about the width of a couple of human hairs, to be imprecise. That's not much of a margin considering the potential ...

There are three important factors forproper bearing installation. First, you should use an arbor press to press-fitthe bearings. This is the most efficient installation method and will preservethe ...

Journal bearing design is complex. It involves optimizing clearances, bearing length, minimum film lubricant, viscosity, flow rate, and inlet slots. Design equations are available, but their solution ...
