采用标准轴承的光电经纬仪轴系误差修正
Elimination of shafting errors in photoelectrical theodolites with standard-bearings
摘要
Abstract
In order to meet the requirements of a tracking gimbal for the lower cost,shorter manufacture periods and higher interchangeable property,a new way of shaft transformation by using standard-bearings to replace thrust bearings was proposed. The axis error sources of using standard-bearings were explained, then according to the principles and characters of the tracking gimbal, an error eliminating method to make the axis sloshing become parallel moving was given. Finally, an experiment model of horizontal axis was designed, and the error of axis adopting zero level deep groove ball bearings was tested and analyzed by the Fourier harmonic analysis method. The experimental results indicate that the maximum error of shafting sloshing has been reduced from 6. 126" to 2. 430", which proves the the feasibility of the proposed error eliminating method. It concludes that the higher level bearings and right fixing plans can meet the precision requirements of small-scale tracking gimbals.关键词
