Abstract: Method and apparatus for automatically dynamically adjusting prestressed bearings of shaft are provided. The apparatus comprises a sleeve assembly having outer and inner sleeves sandwiched between the bearings. An inner diameter of outer sleeve is smaller than an outer diameter of inner sleeve. Hence, outer and inner sleeves are fitted together after cooling. Further, inner sleeve is compressed by the outer sleeve to extend axially. During rotation of shaft, the axial extension of inner sleeve is reduced because the radial expansion of outer sleeve is larger than that of inner sleeve due to an thermal expansion coefficient of outer sleeve larger than that of inner sleeve. This can reduce prestress of bearings without degrading a rigidity thereof.

Abstract: A galvanometer unit comprises a limited-rotation motor, which has axial symmetry of the major motor components including axial placement of the bearings, stator drive coils, and stator back iron with respect to the magnetic center of the rotor, and which employs a cylindrical magnet having significantly uniform properties along its length. The galvanometer employs independently “hard” and “soft” preloaded bearings, which simultaneously minimize axial displacement and account for thermal expansion of the rotor assembly and which improve the overall efficiency of the galvanometer and extend the service life of the bearings.
