Study of horizontal shafting with spherical four-way structure
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 3.3 μ m, 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.
