Focus drive mechanism for the International Ultraviolet ExplorerThe mechanical design of the compact and robust focus drive apparatus developed for the IUE's scientific instrumentation is based on a novel planetary drive that converts the angular increments of a permanent magnet stepping motor into simultaneous linear displacements of three ball screws supporting the secondary mirror. Significant torque margins are thus produced while yielding exceptionally smooth and reliable operation. Attention is given to mechanical drive materials-selection criteria.
