Abstract:
A high speed uniformity measurement device comprising:a pair of rim shafts, one rim shaft of the pair of rim shafts being able to be disposed above and another rim shaft of the pair of rim shafts being able to be disposed below a conveyor which conveys a tire such that the pair of rim shafts sandwiches the conveyor, and each rim shaft of the pair of rim shafts is provided with a half rim for sandwiching the tire, and the pair of rim shafts sandwich or release sandwiching of the tire being conveyed on the conveyor; a load drum which is movable in directions of approaching and moving away from the tire, the load drum applying a load to the tire which is sandwiched between the half rims, while the load drum is pushed against the tire and rotates together with the tire; an air filling and releasing portion for filling the tire sandwiched between the half rims with air, and for releasing air from the tire; and a high speed uniformity measuring portion which measures high speed uniformity in a state in which load is applied to the tire which is filled with air and the rotational speed of the tire is varied.
