Title:
DEVICE FOR MEASURING TREAD RING RIGIDITY AND METHOD FOR MEASURING UNIFORMITY OF TREAD RING
Document Type and Number:
WIPO Patent Application WO/2015/068850
Kind Code:
A1
Abstract:
　A rigidity measurement device of a tread ring (100) comprises a support jig (2) for detachably holding a tread ring (100) unit. The support jig (2) has an open part (21) for deformably exposing a measurement area (100A), which is one portion of the tread ring (100), to the exterior, and a restraining part (22) for essentially non-deformably restraining a non-measurement area (100B), which is an area other than the measurement area (100A) of the tread ring (100). The restraining part (22) inhibits deformation of the non-measurement area (100B), whereby stress is no longer generated in the non-measurement area (100B) and the rigidity of the measurement area (100A) alone can be measured.
