Creep indication system and method for determining creep amount

摘要

A creep indication system and a method for determining a creep amount are disclosed. The system includes a first creep indicating member on a first rotating component and a second creep indicating member on a second rotating component. The second creep indicating member has at least one different creep characteristic from the first creep indicating member. The system further includes at least one measurement device configured to measure a change in radial position of at least one of the first creep indicating member or the second creep indicating member. The method includes measuring a first creep amount of a first creep indicating member and measuring a second creep amount of a second creep indicating member. The method further includes estimating a temperature of a rotating component using the first creep amount and the second creep amount.

主权项

1. A creep indication system, the system comprising:
a first creep indicating member on a first rotating component; a second creep indicating member on a second rotating component, the second creep indicating member having at least one different creep characteristic from the first creep indicating member, wherein the first creep indicating member and the second creep indicating member each includes a cantilevered element initially extending substantially parallel to a longitudinal axis of the respective first rotating component and second rotating component; and at least one measurement device configured to measure a change in radial position of at least one of the first creep indicating member or the second creep indicating member.
