Abstract

The ATST Telescope Mount Assembly uses for the Azimuth axes mechanisms bearing and drive technologies as developed for the machine tool industry. An overview on the ATST mount project and design and its verification by analysis, simulation and tests are given in two separate papers of this conference. This paper describes the main design and accuracy features of the bearing and drive subsystems, their adaption to the ATST mount and their influence on the telescope structural design, and gives a hint to the challenges in the upcoming manufacturing, installation and commissioning phases.
