Design and Measurement of Wheel Assembly for a Wheel-rail Type Pedestal

According to the cone wheel structure of a high-precision phased array radar antenna pedestal system, the spatial relationships between the wheel and track are studied, the computation formulas are concluded and the design scheme for wheel and track is confirmed on this basis. During the installation and adjustment of the wheel on track, the point position coordinate measurement is carried out according to the polar coordinate principle of the laser tracker. The plane is measured directly by the spherically mounted retroreflectors (SMR) to find the normal line direction of the wheel inner plane and the wheel cone plane is measured by SMR together with the fixture to find the center of the circle. The axis and position of the wheel are thus obtained with this method. The result shows that the method can direct the installation and adjustment effectively and meet the centrality and position design requirements of the wheel.
