Measurement system for adjusting trunnion bearing assemblies for a rotary drum

A trunnion roller thrust measurement assembly, comprising:

• a trunnion roller assembly, including:
• a roller configured to provide rotary support of a rotary drum;
• a shaft attached to the roller, the shaft being aligned with an axis of rotation of the roller;
• and
• a bearing housing configured support an end of the shaft;
• a thrust measurement assembly, including:
• a bearing housing end cap attachable to an end of the bearing housing;
• and
• a set of thrust sensors disposed on an outer surface of the bearing housing end cap,
• wherein the set of thrust sensors are configured to sense a thrust force exerted on the bearing housing end cap by an axial displacement of the shaft, and
• wherein an adjustment mechanism is utilized to skew the roller based on the sensed thrust force;
• and
• a distance sensor disposed on the bearing housing end cap,
• wherein the distance sensor is configured to sense a distance between the end of the shaft and a thrust bearing disposed on the bearing housing end cap.
