Altazimuth photoelectric theodolite level shaft U-type and T-type structure  but with the expanding field of applications of photoelectric theodolite  the horizontal shaft structure occur great changes. For example  in the marine environment  shipboard conditions  the instrument has a waterproof  corrosion-resistant  easy maintenance and other functions  while carrier-based optoelectronic devices from a single visible television configure the development of integrated infrared system and ranging system as one of the single-station measurement system  due to the spherical structure has sufficient internal space exactly adapted to this need. In this paper  the horizontal axis of a spherical four-way structure. From aspects of the spherical four-way split in the form and shafting design and finite element analysis of the detailed design. A spherical four-way horizontal axis system  diameter 550mm  weight 19kg sphere  in the 40kg load  the maximum deformation of 3.3m  fully meet the requirements. The shaft of the structure of the shaking is less than 2 arc seconds  the vibration test  the re-examination instrument accuracy change is less than 1 arc seconds. Verify that the structure is stable and reliable. 2012 IEEE.
