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.
