Abstract
Axial alignment detection apparatus for a shaft rotatable about an axis includes alignment indicating means rotatable by the shaft and comprising a plurality of detectable elements; and detector means for detecting the elements and alignment of the shaft as a function of the elements; the elements comprising at least one reference element and at least one alignment dependent element, wherein the reference and alignment elements have a detectable alignment dependent relationship to each other.
Claims11
Apparatus for determining set-up alignment of an axially rotatable shaft, comprising:
- at least two detectable elements disposed on a perimeter rotatable by the shaft for rotation therewith and having a shaft axial position and axial alignment dependent relationship to each other;
- a plurality of sensors radially spaced from said perimeter for detecting the elements as they rotate past the sensors;
- the sensors producing one combined to indicate outputs that the shaft axial position and axial alignment as the shaft is rotated at slow rotation speeds relative to the shaft operating rotational speeds.
