DEVICE FOR MEASURING TREAD RING RIGIDITY AND METHOD FOR MEASURING UNIFORMITY OF TREAD RING

摘要

The apparatus for measuring the rigidity of the tread ring 100 includes a support jig 2 for holding the single tread ring 100 in a removable manner. The support jig 2 includes an opening 21 that exposes the measurement area 100A, which is a part of the tread ring 100, to the outside in a deformable manner, and an area other than the measurement area 100A of the tread ring 100. It has a restraining part 22 which constrains the non-measurement area 100B so that it cannot be substantially deformed. By suppressing the deformation of the non-measurement region 100B by the restraining portion 22, stress is not generated in the non-measurement region 100B, and the rigidity of only the measurement region 100A can be measured.
