DEVICE OF ERROR CONTROL OF SHAFT ROTATION TO CODE CONVERTER Russian patent published in 2015 - IPC G01D18/00 G08C25/00 G01B11/26 

FIELD: instrumentation.

SUBSTANCE: invention relates to the device to control error of conversion of the shaft rotation angle to the code. The device contains reference converter of shaft rotation to code, block interfacing the monitored and reference converters, comprising assembly of rigid connection of shafts of the reference and monitored converters, assembly limiting casing rotation of the monitored or reference converter with installed autocollimating mirror, which angular position is measured by the digital autocollimator. The autocollimator output and outputs of the controlled and reference converters via the electronic block are connected with PC. Assembly limiting casing rotation of the monitored or reference converters provided the casing with all degrees of freedom excluding rotation around the axis of the own shaft, and can be made in form of parallel-link mechanism with spherical linkages.

EFFECT: assurance of the possibility tom increase number of the monitored positions of the converter.
