Axial clearance detection device for large-scale double-row tapered roller bearing

The large-scale double-row tapered roller bearing axial clearance detection device comprises a pedestal, columns, a support frame, a support block and a gauge stand, the pedestal is an annular flat plate, N columns are arranged on the upper surface of the pedestal in an annular array, the support frame is located at the upper parts of the N columns and is respectively connected with the top ends of the N columns, and the support block is connected with the gauge stand. N sliding grooves are formed in the upper surface of the supporting frame, each sliding groove is internally provided with a supporting block, the upper surface of each supporting block is provided with a positioning step, and the positioning steps of the N supporting blocks jointly position the height and the circle center of the measured bearing inner ring; the meter frame is installed in the middle of one stand column, and a measuring meter is installed on the meter frame. The axial clearance detection device can directly detect the axial cl
