UNIVERSAL WHEEL RUNOUT MEASUREMENT DEVICE

Abstract

This invention relates to a universal wheel runout measuring device that enables the simultaneous measurement of radial runout on the inner and outer tire seating surfaces and axial runout on the inner and outer wheel lugs of wheels of different diameters and widths. The device comprises a wheel fixing rotary table (7) that rotates on bearings (10, 11), a centering shaft (8), and a centering hub (6) whose conical surface is clamped into the wheel center hole. Each of the two opposing comparator holder arms (3) that can be adjusted in slots on the table (2) has a rotating shaft (4) carrying two comparators (5) that can be positioned according to the wheel width. In the front view of the device, the comparators in the left group measure the radial runout, and those in the right group measure the axial runout of the wheel lugs. The rotating shafts (4) can be moved a minimum of 45 degrees forward or backward from the measuring position; they are locked by a spring ball only when the opposing comparator groups are in the parallel measuring position.Thus, the four runout values ​​are measured simultaneously during one rotation of the rim.
