Abstract

The embodiment of the invention provides a shafting error measurement method and system, and the method comprises the steps: carrying out the N equal division and N + 1 equal division of a dial disc through a plurality of reading heads, and enabling the reading heads which carry out the equal division of the dial disc to comprise a common reading head; in the movement process of the rotating shaftsystem, obtaining the output angle values of the reading heads, and obtaining a static error compensation curve according to the output angle values; arranging at least two groups of reading heads onthe dial disc, obtaining the reading of the reading heads at the preset moment, obtaining multiple groups of measurement data, wherein each group of reading heads comprises two reading heads, and theincluded angle of each group of reading heads relative to the circle center of the dial is equal; according to the multiple sets of measurement data, arranging the measurement data in sequence, obtaining the shafting dynamic error of the whole-cycle shafting according to the static error compensation curve and the measurement data, performing grouping, translation and difference processing on theshafting dynamic error to construct a shafting error curve.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of precision turntable error compensation, and in particular to a method and system for measuring shaft error. Background technique [0002] The angle measurement system is a key functional component in the fields of national defense equipment, aerospace, advanced manufacturing, test measurement and precision instruments, such as various turntables, tracking, maritime patrol searchlights, astronomical telescopes and precision measuring instruments. [0003] The errors of the angle measuring system mainly include engraving error, installation error, electronic subdivision error and error caused by shaft runout, among which the most influential one is the error caused by shaft runout. Compared with other factors, the mechanical shaft runout has a greater impact on the angle measurement error, and more importantly, it is variable and difficult to eliminate. Therefore, if the angular accur...
