Lovejoy® ROSTA® Tensioner - Power Plant’s Driving Force
|
| Power has no season. Whether summer heat demands air
conditioning or dusky winter evenings call for extra lights
and electric blankets, consumers use electricity. In a coalfired
power plant, equipment must operate 24 / 7. Coal-fired
power plants utilize multiple coal pulverizers to generate
this electricity. Pulverizing coal results in less emissions and
is more efficient use of fuel. Constellation Energy’s H.A.
Wagner power plant in Baltimore, MD, was experiencing
costly downtime, maintenance and material expenses
associated with V-belts on a coal pulverizer drive system. |

Torque Arm Design Considerations for Shaft Mounted Speed Reducers
|
| In the power transmission industry, shaft mounted speed reducers provide one possible solution to meet the speed
reduction/power generation needs for an application. As the name implies, a Shaft Mounted Speed Reducer (also
known more simply as SMSR) is a speed reducer mounted directly onto, and statically supported by, a driven shaft -
that may be found on a conveyor. Typically, the SMSR incorporates a hollow bore (keyed, Taper-Grip® bushing, etc.) to
facilitate mounting onto the driven shaft. |
