DYNAMIC BIAXIAL BENCH Russian patent published in 2014 - IPC G01C25/00 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of measurement equipment, in particular, to testing equipment for calibration of instruments of a navigation and survey control. In a mounting site of the inner frame of the dynamic biaxial bench there are cylindrical sectors with through slots made along arcs of circumference concentrically to external and internal surfaces. Each sector is installed on a pin as capable of movement in a circumferential direction, on the internal surface of each sector there is a cylindrical groove, by means of which sectors are coupled with the external surface of the ring, the axis of which is perpendicular to the axis of rotation of the external frame. One end of the pin is installed into a fastening hole of the tested device, and the other end is screwed into a threaded hole of the mounting site of the inner frame.

EFFECT: higher accuracy of a dynamic biaxial bench.
