ABSTRACT:
A device for accommodating and measuring thrust loads on a rotatably mounted shaft wherein the thrust loading is in either axial direction. The rotatably mounted shaft has two shoulders facing in opposite axial directions which cooperate with a pair of thrust bearings to constrain the shaft to a limited range of axial movement. Thrust rings associated with the shoulders are positioned between the shoulders and the bearings and are biased toward the bearings by resilient members to resist the axial movement of the shaft between the bearings. Sensing systems are arranged to measure the axial displacement of the shaft and provide input to thrust monitoring and control systems. A method for preventing damage to labyrinth seals on the shaft during start up of the equipment is also provided.
