Abstract

See full text

A recorder for documenting that a shaft in a rotating machine has been rotated while the rotating machine is stored or otherwise out of service. The recorder includes an elongated strip that is wound on a reel disposed adjacent the shaft. The reel is rotatable about an axle that is spaced away from the shaft. A free end of the strip is secured to an outer surface of the shaft and spools onto the shaft as the shaft is rotated, and which unwinds the strip from the reel. Markings are on the strip representing distance from the free end, which visually indicate occurrence and amount of shaft rotation. Types of markings include different colors or patterns, and which change at distances corresponding to shaft circumference. Alternatively, the markings are metered increments illustrating linear distance.
