Abstract: Based
on the review of international patent technology on two shafts
alignment, the important issues related with two shafts alignment in
terms of three-dimensional coordinates are conducted. The laser
alignment project plane of synchronous circumrotated shaft is described
in three-dimen- sion. Analysis geometric problem of coaxiality error
measurement is solved in terms of synchronous circumrotating posi- tion
coordinates. Spatial coordinate changes of an electro-op- tical
measuring device are demonstrated using experiments. Original oval curve
which laser light spot on plane of perpendicular one shaft, has been
changed on the plane of electro- optical measuring device. It is very
clear that the angle and coaxiality error between two shafts influences
the curve on plane of electro-optical measuring device.
