Title:
METHOD AND DEVICE FOR MEASURING SHAPE OF TREAD
Document Type and Number:
Japanese Patent JP2017009483
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for measuring the shape of a tread, capable of promptly calibrating values measured by a plurality of displacement meters even in an environment easily affected by atmospheric temperature to enhance the accuracy of measurement.SOLUTION: A method for measuring the shape of a tread, capable of measuring the surface shape of the tread part of a tire to be measured using a plurality of non-contact type displacement meters comprises: the arrangement step S1 of arranging each displacement meter at an interval in the direction of a tire shaft so that a calibration measurement region being a part of each measurement region overlap to each other; the measurement step S2 of measuring distance data from each displacement meter to the surface of the tread part of the tire to be measured, by each displacement meter; and the calibration step S4 of calibrating the distance data measured in the entire measurement region of at least one displacement meter on the basis of the distance data measured by each displacement meter in the calibration measurement region.SELECTED DRAWING: Figure 2
