Fluid Drive Upgrades

April 25, 2017

TRI has new tilt pad bearing designs for upgrades to the Size 270 Dual Circuit Fluid Drive. These bearings replace fixed bore pressure dam bearings and are essential for vibration control under high torque conditions.

The image below replace the bearing and the bearing housing on the output-outboard end of the fluid drive. It’s a 6 pad bearing with 2 thermocouples in the bottom pad and vibrations probes at 45┬░ off of the vertical center-line.

New Tech Note

February 8, 2013

It has been nearly two years since our last Tech Note, but today we have released the latest write up. This month’s topic is about bearings for turbine-generators found in nuclear electric generation plants.

Many nuclear plants run at 1800 RPM where many fossil fueled steam plants run at 3600 RPM. Considering the generator, half the speed means twice the poles dramatically increasing the weight of the rotor.

The new Tech Note focuses on heavily loaded bearings.
